Summarizing the part data in the tool sheet documentation1.4
SolidCAM2008 R12 provides you with an advanced option to summarize the CAM-Part information by generating a tool sheet documentation in PDF format.
Definition of tool sheet parameters1.4.1
The Tool Sheet command is available for the complete CAM-Part (in the right-click menu available on the CAM-Part header) or for separate operations (in the right-click menu available on the operations). The Tool Sheet Extra Parameters dialog box is displayed. This dialog box enables you to manage the content of the documentation PDF file.
In this dialog box, you can attach a logo file (in BMP format) to your tool sheet, define your own variables and values that will be inserted into the tool sheet, add comments and notes relative to your part, and decide whether you need the full version of the information sheet or only particular sections, such as Operations summary or Tool
Table.
The Show Last Tool Sheet command enables you to display the last generated tool sheet for the current part, instead of generating it anew. The Tool Sheet Extra Parameters dialog box is displayed so that you can define which sections of the last tool sheet you want to display.

Opening of PRT files by double-clicking1.5
In the previous versions of SolidCAM, it was only possible to open a PRT file by using the SolidCAM submenu in the main menu of SolidWorks, i.e. to open a CAM-Part file, you needed to load SolidWorks, click SolidCAM, Open, and then choose the required file from the CAM-Parts browser. SolidCAM2008 R12 provides you with a time-saving possibility to open a PRT file by double-clicking on the file name in any location where it is saved.
![Page 19: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/19.jpg)

3D geometry selection1.6
In previous SolidCAM versions the Select/Unselect radio button was used in dialog boxes for 3D geometry selection (solids, surfaces and faces). This radio button switches the system between selection and unselection modes.
SolidCAM2008 R12 provides you with an improvement of the selection/unselection of the 3D geometry. This improvement is based on automatic toggling between modes: a click on the model entity selects it, while the next click on the selected entity clears the selection.
The Select/Unselect radio buttons are therefore removed from the relevant dialog boxes (3D Geometry
dialog box, 3D Box dialog box, Select faces dialog box etc.)

Templates1.7
SolidCAM2008 R12 provides you with the functionality of templates that is useful for simplifying the repetitive tasks in the CNC programming. SolidCAM enables you to save the operation data as a template and load it into a new operation of the same type. SolidCAM enables you also to specify the default operation template that is used for each newly created operation of the appropriate type.
SolidCAM enables you also to define and use a Process Template, which is a template of a series of operations that executes a specific machining task.
Operation Template1.7.1
SolidCAM enables you to create an operation template by saving an already defined operation. The saved template can be later used for a new operation definition. The saved template data does not include the geometry which must be defined after loading the template. The saved template can optionally include the tool data.
The Template section is added into each SolidCAM Operation dialog box. This section provides you with the following functionality:
![Page 21: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/21.jpg)
1.General
21
Save Template
The button enables you to save all the data (except the geometry) of the current operation as a template.
The Template Manager dialog box is displayed. This dialog box enables you to choose the name for saving the template. The template is saved in the location defined by the SolidCAM Templates Directory parameter in the Part Settings dialog box (see topic 1.7.4).
The Operation Templates table displays all the Operation Templates located in the SolidCAM
Templates Directory and their types.
The Include tool data check box enables you to include the tool data in the saved template.
Type the name in the Template edit box and click on the OK button to confirm. If a template with the defined name already exists in the current location, SolidCAM displays the following warning message:
When you confirm this warning by the Yes button, SolidCAM overwrites the existing template with the new one. When you press the No button, the Template Manager dialog box is activated again providing you with the possibility to choose a different name for the template.
![Page 22: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/22.jpg)
22
SolidCAM enables you also to save an existing operation as Operation
Template from the SolidCAM Manager, using the Create Template
command from the right-click menu available on single operations.
This command displays the Template
Manager dialog box which enables you to save the template data as described earlier.
![Page 23: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/23.jpg)
1.General
23
Load Template
The button enables you to load a specific template into the current operation. The
Template Manager dialog box is displayed.
This dialog box offers you the templates located in the SolidCAM Templates Directory
determined by Part Settings (see topic 1.7.4).
The Template Manager dialog box displays only the templates whose type is suitable for the current operation.
Choose the necessary template and click on the OK button to confirm the operation. When the template is loaded, all the current operation data are substituted with the data from the template.
When a template is loaded into the operation, its name is displayed in the edit box in the Templates section. A tool tip message is available when you place the mouse cursor over the edit box; the tool tip message displays the full name of the loaded template.
When any of the operation data is modified after a template is loaded, the template name in the edit box is marked by an asterisk sign (*).
![Page 24: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/24.jpg)
24
SolidCAM enables you also to create a new operation from an existing template, directly from the SolidCAM Manager using the Add Operation from Template command from the right-click menu available on the operations header or on single operations.
This command displays the Template
Manager dialog box which enables you to choose an existing template as described earlier. In this case the Template Manager
dialog box displays all the templates existing in the SolidCAM Templates Directory
regardless of its type.
When the dialog box is confirmed by the OK button, SolidCAM inserts the chosen Operation Template into the SolidCAM
Manager tree.
The inserted operation is incomplete since the operation has no defined geometry and no tool (if the initial Operation Template used for the operation creation had no tool). The incomplete operations are marked with red color.
Since the incomplete operation has no geometry, its tool path cannot be generated. In order to completely define the operation, you have to define its machining geometry and tool (if necessary).
During the creation of a new operation from an Operation Template, SolidCAM assigns the Machine Coordinate System #1 (Position #1) for the newly created operation. During the operation editing this Coordinate System can be changed.
![Page 25: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/25.jpg)
1.General
25
Tool search
When an operation template is loaded, SolidCAM checks the existence of the tool data in the template; if the tool data was saved in the operation template, the tool search is performed according to the following rules:
• When the operation template uses a tool defined as Permanent, the tool search for this tool is performed using the tool number only. At the first stage, the tool search is performed in the Part Tool table. If the tool with the defined number is not found in the Part Tool Table, SolidCAM performs an additional search in the Current Tool Table. If a tool with the defined tool number is found in the Current Tool Table, it is copied into the Part Tool Table and chosen for the operation. If the tool is not found in the Current Tool Table, SolidCAM displays the following error message:
When you confirm this message with the OK button, SolidCAM returns you to the operation dialog box in order to define a tool.
• When the tool in the operation template is not defined as Permanent, SolidCAM performs the tool search using the tool parameters. The tool parameters used for the tool search are defined in the SolidCAM Settings in the Tool search page. The tool search is performed in the Part Tool table. If a tool with the same definition as in template is not found in the Part Tool
Table, SolidCAM performs an additional search in the Current Tool Table. If a suitable tool is found in the Current Tool Table, it is copied into the Part Tool
Table and chosen for the operation. If a tool is not found in the Current Tool
Table, a new tool with the parameters defined in the template is created in the Part Tool Table. SolidCAM automatically assigns the first not used tool number for the new created tool.
When you load a template containing tool data into an operation that already has a defined tool, SolidCAM displays the following message:
When you confirm this message, SolidCAM replaces the tool already defined in the operation with the tool defined according to the template.
![Page 26: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/26.jpg)
26
Process template1.7.2
SolidCAM2008 R12 enables you to define and use a Process Template, which is a template of a series of operations that executes a specific machining task. Such capability enables you to store a complete sequence of operations as a Process template and apply it for the machining of similar cases.
Define Process Template
To create a Process Template, select in the SolidCAM Manager all the operations intended to be included in the Process Template and choose the Create Template command from the right-click menu available on single operations.
This command displays the Template Manager
dialog box which enables you to save the chosen operations as a Process Template.
This dialog box displays all the existing Process Templates in the SolidCAM Templates Directory; the Process Templates names are listed in the Template Folders section under the Process Templates header. The sequence of operations comprising the template is displayed in the Operation Templates table.
![Page 27: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/27.jpg)
1.General
27
The Include tool data check box enables you to include the tool data into the saved Process Template.
To save the selected operations as a new Process Template, type the name in the Process Template edit box and click on the OK button to confirm the operation. If a Process Template with the defined name already exists in the current location, SolidCAM displays the following warning message:
When you confirm this warning by the Yes button, SolidCAM overwrites the existing Process Template with the new one. When you press the No button, the Template
Manager dialog box is activated again providing you with the possibility to choose a different name for the Process Template.
The Template Manager dialog box provides you with the capability to create an empty Process Template and copy to it a number of Operation Templates from different Process Templates. See topic 1.7.3 for more details.
Use Process Templates
SolidCAM enables you to insert the Operations Templates contained in a Process Template into a CAM-Part, converting them into regular SolidCAM Operations. To insert a Process Template into the CAM-Part choose the Add
Process Template command from the right-click menu available on operations header or single operations in the SolidCAM Manager.
![Page 28: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/28.jpg)
28
This command displays the Template Manager dialog box which enables you to choose an existing Process Template to be inserted.
During creation of a new operation from the Process Template, SolidCAM displays the CoordSys selection dialog box, which enables you to choose the Coordinate System to be used in the created operations.
The inserted operations are incomplete; this means that the operations have no defined geometry and no tool (if the initial Operation Template used for the operation creation had no tool). The incomplete operations are marked with red color.
Since the incomplete operations have no geometry, their tool path cannot be generated. In order to completely define the operation, you have to define the machining geometry and tool (if necessary) for each operation.

• The Browse button displays the browser dialog box that enables you to choose another location for the SolidCAM Templates
directory.
By default, the Templates directory location is ..\Tables\Metric\Templates for Metric units and ..\Tables\Inch\Templates for Inch units.
Operation default templates
The Operation default templates section enables you to assign default templates for operations.
The templates are divided between four tabs:
• The 2.5D Milling tab contains the 2.5D milling operations.
• The 3D Milling tab contains the 3D milling operations.
• The HSM tab contains the HSM operations.
• The Sim. 5-Axis tab contains the Sim. 5-Axis operations.
Each tab contains a table that enables you to define the default templates of each SolidCAM operation. When the default template use is activated for a specific operation, the Template column enables you to use the suitable template with the combo-box. When the template use is activated for an operation type, each new operation of this type will be started with the data of the specified template.
![Page 34: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/34.jpg)
34
Templates activation/deactivation
When user deactivates template use for an operation, the Template column combo-box is disabled.
When you activate template use for an operation type, SolidCAM searches in the SolidCAM Template Directory for suitable templates of this type. The combo-box is filled with the names of the found templates; the first of them is automatically chosen. In case of absence of suitable templates, SolidCAM deactivates the use of templates for this operation.
Changing SolidCAM Template Directory
When you change a SolidCAM Template Directory, SolidCAM performs a search for suitable templates for all the operations with the activated default template use. When a template for some operation is not found, SolidCAM deactivates the default template use. Found templates are inserted into the related combo box. The first found template name is displayed.
The templates search is not performed for the operations where the templates use is deactivated.
Creating templates sets (working style)
Consider a folder containing a set of templates. This set contains only one template for each specific operation; all the operations are thus covered by templates. This set is customized for a specific application (e.g. Mold machining). Consider an additional folder containing a set of templates for another application.
By switching between these folders for SolidCAM Template Directory, SolidCAM switches templates for all the operations. This enables you to quickly choose a templates set for a specific application.

Automatically synchronize geometries
The Automatically synchronize geometries option enables SolidCAM to perform the geometries synchronization automatically.
This option is enabled only when the Check synchronization always option is chosen.
When the Automatically synchronize geometries option is activated, SolidCAM performs the synchronization check and then automatically synchronizes all the unsynchronized operations and geometries. When the synchronization fails for certain operations or geometries, SolidCAM marks the operations/geometries with an exclamation mark and deletes the operations tool paths; such operations are marked with the asterisk.
Calculate operations after the synchronization
The Calculate operations after the synchronization option enables you to automatically perform the calculation of the synchronized operations.
This options is enabled only when the Automatically synchronize geometries
option is activated.
When the Calculate operations after the synchronization option is activated, SolidCAM automatically calculates all the synchronized operations; the operations marked with the exclamation mark are not calculated.

Closing geometry chains by extending chain entities2.1
The Curve option commonly used for geometry chains selection enables you to select a continuous geometry chain by picking its successive entities. During the geometry definition SolidCAM detects the gaps between selected entities and provides you with the capability to close them, taking into account the Gap Minimum and Gap Maximum parameters defined in the SolidCAM Settings.
If the detected gap is smaller than the Gap Minimum tolerance, SolidCAM automatically closes the gap by extending/shortening chosen entities up to their virtual intersection point. If the gap is greater than the Gap Minimum tolerance but less than the Gap
Maximum tolerance, SolidCAM displays a prompt message asking you if you want to close the gap. When you confirm, SolidCAM automatically closes the gap by extending/shortening chosen entities up to their virtual intersection point; if you cancel, SolidCAM does not close the gap and unselects the last entity.
When the gap is larger than the Gap Maximum tolerance, SolidCAM does not accept the chosen entity and displays a warning message.
SolidCAM2008 R12 provides you with the Curve + Close
Corners option of the chain geometry selection. This option enables you to close the gaps between successive chain entities irrespective of the Gap Minimum and Gap
Maximum values.
![Page 45: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/45.jpg)
2. Geometry
45
When a gap is detected between two successively selected entities, SolidCAM continues the chain by virtually extending the selected entities, according to the direction of the first entity, up to a virtual intersection point between the two entities.
In case several possible intersection points exist, the point closest to the last vertex of the first selected entity is chosen.
If an intersection point cannot be found by extending either one or both selected entities, the following message is displayed.
Splines and arcs are extended by lines tangential to the arc/spline at its end point.
Associativity and synchronization
When the model used for the geometry definition is modified, SolidCAM enables you to synchronize the geometry with the updated model. During the synchronization SolidCAM handles the gaps areas (closed using the Curve + Close Corners option) by regenerating the extension of the chain elements so as to close the gaps.

Geometry modification for specific operation2.2
SolidCAM enables you to share geometries between a number of SolidCAM operations. SolidCAM2008 R12 provides you with the additional capability to modify a shared geometry, specifically for each operation; this includes assigning different values to the geometry Extension, Offset and Define Start. The geometry modification also includes choosing which geometry chains are active in the operation (in case of multiple chain geometry). The modification is relevant only for the current operation and does not affect other operations where the geometry is shared. The geometry modification is supported for the Profile, T-Slot and Translated Surface operations.
The Geometry button is added to the Modify section of the Technology page of the operation dialog box.
This button displays the Modify Geometry dialog box. This dialog box enables you to perform the geometry modification for the current operation.

Synchronization when design model configuration changes2.4
In previous SolidCAM versions, SolidCAM provided you with a constant link between the geometry and the design model configuration which was used for the geometry definition (parent configuration). With such a link, switching between configurations of the design model does not affect the defined geometry; the geometry can be updated (through synchronization), only in case the parent configuration is modified.
SolidCAM2008 R12 provides you with an additional functionality that enables you to synchronize the geometry, when the configuration changes; SolidCAM discontinues the link between the geometry and its parent configuration and establishes a new link between the geometry and the new current configuration. Such functionality enables you to automatically update SolidCAM geometries according to the current configuration of the design model.
This functionality enables you for example to perform, in a single CAM-Part, the machining of a family of similar parts, based on a single design model and managed by configurations. The geometries of this CAM-Part are automatically updated for each current configuration, providing you with an updated tool path.
SolidCAM Settings
The Synchronization when design model configuration
changes section is added to the Synchronization page of the SolidCAM Setting dialog box. This section enables you to define SolidCAM behavior in case when the configuration is changed.
The SolidCAM Settings are used as the default for the Part Settings of each newly defined CAM-Part.

The Synchronization page is added to the Part Settings dialog box. This page enables you to define SolidCAM behavior in case when the configuration is changed for the current CAM-Part. The Synchronization when design model configuration changes section provides you with the following options:
The Keep the geometry associative with the parent configuration option enables you to keep the link between the geometry and the parent configuration. SolidCAM always keeps the geometry linked to the parent configuration (the configuration used for the geometry definition). When you switch between the model configurations, this does not affect the geometry; synchronization is required only in case when the parent configuration is changed.

End Mill / Bull nose mill / Ball nose mill3.1
The End/Rough Mill tool type, used is previous SolidCAM versions, is reclassified into three separate tool types: End mill, Bull nose mill and Ball nose mill, according to the Corner radius value.
End mill3.1.1
A tool of this type is defined by the parameters shown in the image. Note that the Corner radius parameter, used for the tool definition in previous versions, is not used any more for the End Mill tool definition.
The cylindrical tool arbor is added to the tool definition. The arbor diameter and length are defined by: Arbor Diameter and (Total Length - Shoulder Length). The Shoulder Length should be greater than or equal to the Cutting Length, and equal to or less than the Outside Holder Length.
When a new tool is created, the default value of the Arbor Diameter is equal to the Diameter value. The default value of the Shoulder Length is equal to the Cutting Length.

Bull nose mill3.1.2
A tool of this type is defined by the parameters shown in the image. The Corner radius of a tool of the Bull nose
mill type should be in the range from 0 to half the Diameter value.
The cylindrical tool arbor is added to the tool definition, same as for the End
mill tool.
Ball nose mill3.1.3
A tool of this type is defined by the parameters shown in the image.

Tools conversion
SolidCAM automatically converts tools of the End/Rough Mill tool type, created with previous SolidCAM versions, into one of the three tool types described above. The tools conversion is performed according to the Corner radius value:
• Tools with zero Corner radius are converted into End mill tool type.
• Tools with Corner radius equal to half the Diameter are converted into Ball
nose mill type.
• Tools with Corner radius in the range from 0 to half the Diameter value are converted into Bull nose mill type.
When an existing tool (created in a previous SolidCAM version) is converted into End mill / Bull nose mill / Ball nose mill tool, the value of the Arbor Diameter is defined as equal to the Diameter. The value of the Shoulder Length is defined as equal to the Cutting Length.
![Page 62: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/62.jpg)

In previous SolidCAM releases the flutes were considered to be only on the conical face (flutes length and cone length were defined by the Cutting Length value). In SolidCAM2008 R12, the cone length and flutes length are defined by separate parameters. The Cone Length is determined by the Diameter, Taper angle and Tip diameter parameters. The Cutting Length parameter defines the length of flutes. The flutes can be located at the conical and cylindrical faces of the tool.
You choose one of the check boxes, at the side of the Tip Diameter and Cone Length
edit boxes, in order to define the taper tool using either the Tip diameter or the Cone
Length.
When the Tip Diameter check box is selected, the Cone Length check box is unselected and the relevant edit box is disabled; the Cone Length value is thus automatically calculated.

Tool Units3.18
In previous SolidCAM versions, the tools in the tool library were saved without the units data. When a tool was loaded into a CAM-Part, its dimensions were interpreted according to the CAM-Part units; therefore it was impossible to use tools with different units than the units of the CAM-Part.
SolidCAM2008 R12 provides you with the possibility to assign units data for each tool in the tool library. The tool library can store tools of different units. Such functionality enables you to use tools, defined in different units than the units of the CAM-Part, without converting the tool parameters into the CAM-Part units. You can choose the units for the tool diameter values and tool lengths separately.
The Mm/Inch radio buttons are also added to the Default Tool data page. These radio buttons enable you to define the units used for the speed/feed definition. In the Part
Tool Table, these radio-buttons are disabled; the units of the CAM-Part are used.

The definition of the Face Milling Operation is mainly similar to the regular Pocket
operation, except for a number of parameters related to face milling.
The Technology page of the Face Milling Operation dialog box provides you with the following parameters:
Technology
SolidCAM enables you to choose the following technologies for the face milling:
• Hatch
With this strategy the machining is performed in a linear pattern. The Data button displays the Hatch data dialog box which enables you to define the hatch parameters.
The Hatch parameters used for the Face milling are similar to the parameters used for the Hatch strategy of the regular Pocket operation.
![Page 101: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/101.jpg)

4. Milling
During face milling the tool path is extended over the edges of the machined face. The Extension section enables you to define the extension both along the tool path (the Along section) and across the tool path (the Across section). The extension can be defined either by percentage of the tool diameter (the % of tool diameter option) or by value (the Value option).
• Contour
With this strategy the machining is performed in a number of equidistant contours. The Data button displays the Contour data dialog box which enables you to define the contour parameters in the same manner as for the Contour strategy of the Pocket Operation.
The Contour parameters used for Face milling are similar to the parameters used for the Contour strategy of the regular Pocket operation.

Similar to the Hatch strategy, the Contour tool path can also be extended over the machined face edges. The Extension section enables you to define the extension of the tool path, same all around. The extension can be defined either by percentage of the tool diameter (the % of tool diameter
option) or by value (the Value option).
• OnePass
With this option, SolidCAM performs the face milling in one pass. The direction and location of the pass is calculated automatically, taking into account the face geometry, in order to generate an optimal tool movement with the tool covering the whole of the geometry.
The Data button displays the One Pass data dialog box which enables you to define the machining parameters.

The Extension section enables you to define the tool path extension over the face edges. The extension can be defined either by percentage of the tool diameter (the % of tool diameter option) or by value (the Value option).
The Overlap section enables you define the tool overlapping between two successive passes. This section is enabled for Hatch and Contour strategies only.
Offsets
The Offsets section enables you to define the value of the Floor offset, the machining allowance that is left unmachined on the face during the rough machining.
The Finish check box enables you to remove the remaining offset with the last cut (if the check box is selected) or leave the offset unmachined for further operations (if the check box is unselected).
Sort cut order
The Complete Z-level option enables you to define the order of the machining Z-levels, in case more than one face is machined. The behavior of this option is similar to its behavior in the Pocket Operation.

Vertical zigzag passes in Profile operation4.5
In previous SolidCAM versions the linking of the profile machining passes, located at successive Z-levels (defined with the Step down parameter), was performed by rapid movement up to, at and down from the Clearance level. At the end of each pass the tool performs a retreat movement to the operation Clearance level, a horizontal movement at rapid feed to the beginning point of the next pass and then descends to the Z-level of the next pass. With this method SolidCAM keeps the same cutting direction (either climb or conventional) along the whole tool path.
SolidCAM2008 R12 provides you with the possibility to connect the passes, located at two successive Z-levels, directly from the end of a pass to the beginning of the next pass. With this connection method the machining is performed in a zigzag manner; the machining changes to the opposite direction from one pass to the next.
The Depth cutting type section is located in the Technology page of the Profile operation dialog box. This section enables you to switch between the One
way and Zigzag options.
When the One way option is chosen, the cutting passes are oriented in the same direction and connection between them is performed through the operation Clearance level.
When the Zigzag option is chosen, the tool path is performed in a zigzag manner, with the tool path direction changing from one pass to the next.
The Zigzag option cannot be used together with the Clear offset
technology.
![Page 105: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/105.jpg)

4. Milling
Lead in and Lead Out
When the Lead In/Out strategies are used together with the Zigzag option, SolidCAM calculates the lead in/out movements for all the cuts according to the direction of the first cutting pass, irrespective of the direction of the other cutting passes. During the tool path linking, SolidCAM connects the cuts (containing lead in and lead out movements) in a zigzag manner and changes the direction of all even cuts to the opposite. Therefore only for odd cuts, the Lead in strategy is used for the lead in and the Lead Out strategy is used for the Lead Out. For even cuts the Lead In strategy is used for the Lead Out and the Lead Out strategy is used for the Lead In.
Tool side and compensation
When the Zigzag option is used, the Tool side combo-box defines the tool location for the first cut. For each successive cutting pass, the tool position, relative to the geometry direction, is changed.
When the compensation is used for the tool path linked using the Zigzag option, SolidCAM takes into account the machining direction and the changes in the tool position, relative to the geometry direction, for each successive cut. The different compensation commands are used in the GCode output for even and odd cuts.

Equal step down in Profile and Pocket operations4.6
In previous SolidCAM versions, the machining of the Profile and Pocket operations started from the Upper level and continued on a number of successive Z-levels till the operation Depth (modified with the Floor offset and Delta depth
parameters). The distance between two successive Z-levels was determined by the Step down parameter. If the machining depth was not divisible exactly by the Step
down parameter, the depth of the last cut was less than the Step down parameter.
SolidCAM2008 R12 provides you with the Equal step down option that enables you to keep an equal distance between all Z-levels. With this option you have to specify the Max. Step down parameter (instead of the Step down parameter).

Wall Draft angle in Profile and Pocket operations4.8
In previous SolidCAM versions, it was possible to perform Profile and Pocket operations on vertical walls only.
SolidCAM2008 R12 enables you to perform the machining of walls inclined with a constant draft angle along all the geometry.
The Wall draft angle button is added to the Technology
page of the Profile and Pocket operation dialog boxes. This button displays the Wall draft angle dialog box.
When the Wall draft angle check box is activated in the dialog box, the inclined wall machining is performed.
The External wall angle parameter defines the draft angle of the wall; the angle is measured from the Z-axis direction as shown.
The Islands wall angle parameter defines the draft angle of the island walls. This parameter is relevant only within the Pocket operation; the angle is measured similar to the External wall angle parameter.
![Page 111: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/111.jpg)

4. Milling
For the inclined wall machining, each cutting pass located at a specific Z-level is generated according to the specified External/Island wall angle parameter.
The External corner type option enables you to define how the cutting passes will be connected during the external corners machining. The following possibilities are available for two possible types of corners in the geometry model:
If the geometry model has sharp corner there are two options for creating tool path at the corner:
• Sharp Corner. With this option the tool path is calculated in such a way so as to perform the machining of a sharp corner.
• Conicalfillet. With this option the tool path is calculated in such a way so as to perform the machining of the corner with a conical fillet; the radius of the tool path rounding increases from one pass to the next.
If the geometry model has filleted corner there is one option for creating tool path at the corner:
• Cylindricalfillet. The tool path is calculated in such a way so as to perform the machining of the corner with a cylindrical fillet; the radius of the tool path rounding is the same for all the cutting passes.

Profile floor machining4.9
In previous SolidCAM versions, the Profile operation enabled you to define a machining allowance in XY direction (Wall offset), leaving it unmachined during the profile roughing and removing it during the finishing passes (within the same operation or within another Profile operation).
SolidCAM2008 R12 provides you with the possibility to define a similar allowance in the Z-direction (Floor offset). This Floor offset is left unmachined during the profile roughing and removed during the finishing.
The Floor offset parameter is added to the Offsets section, located on the Technology page of the Profile operation dialog box.
The Floor offset parameter is available only when the Rough section is activated.
When the Floor offset is specified, SolidCAM performs the machining by the Z-levels defined with the Step
down parameter. The machining is performed up to the Floor offset from the Profile depth.
The Clear offset section enables you to define the parameters of the Clear
offset machining for the roughing and finishing passes.

The use of the Clear offset option for the Profile finishing enables you to perform the machining of both the Wall and Floor offsets. In this case, SolidCAM performs first the machining of the floor area and then the walls.
The floor area is machined with a single cutting pass at the Profile depth. This cutting pass is calculated using the Clear offset strategy (with the specified Offset and Step over parameters) and taking into account the specified Wall offset.
The wall finishing is performed from the Upper level till the Profile Depth in a number of steps defined with the Step down parameter.

Pocket Wall finishing4.10
In previous SolidCAM versions, the pocket walls finishing was performed with a single cut at the whole Pocket
depth.
SolidCAM2008 R12 enables you also to perform the finishing of the walls in a number of successive cuts, with the distance between them defined by the Step down parameter.
The Depth section is added to the Finish section of the Pocket operation dialog box.
This section enables you to choose how the wall finish will be performed: either at the whole depth (Total depth option) or in a number of steps at each step down (Each step down option).
The options of the Depth section are available only when the wall finishing is performed in the operation (the Wall or Floor option is used for the Finish).
When the Wall draft angle option is used in the operation, the Depth options are disabled and the Each step down option is used for the Wall finishing.

The Select section enables you to choose the selection method. When the Single entity
option is chosen, SolidCAM enables you to pick single entities in order to mark them in order to mark them as open/closed. When the From/To entities option is chosen, SolidCAM enables you to mark a segment of the pocket geometry by picking the start and the end entities.
The CAD Selection button enables you to perform the selection using the CAD tools.
Open pocket machining parameters4.11.2
The Open Pockets section is added to the Technology page of the Pocket operation dialog box. This section is enabled only when the pocket geometry contains open edges.
During the Open pocket machining the tool path is extended beyond the open edges. The Extension section enables you to define the overlapping between the tool and the open edges; the overlapping can be defined either by percentage of the tool diameter (the % of tool diameter option) or by value (the Value option).
The Use profile strategy option enables you to perform the Open pocket machining in a Profile manner. The tool path at a specific Z-level consists of a number of equidistant profiles starting from outside the model (at the distance defined by the Extension parameter). The tool moves in parallel offsets to the pocket geometry.

4. Milling
The One way/Zigzag options enable you to define the tool path direction and linking.
• With the Zigzag option, the tool finishes one profile pass and then directly moves to the next pass. The machining is performed without leaving the material, thus constantly switching between climb and conventional milling.
• With the One way option, the tool finishes one profile pass, then rapidly moves (G0) to the safety distance and then to the start of the next cutting pass. The cutting direction (either climb or conventional) is preserved for each cutting pass.
The Approach from outside option enables the tool to approach from outside of the material in the open pocket areas, if possible. Such an approach enables you to decrease the tool loading when plunging into the material. This option enables SolidCAM to perform the approach movement from an automatically calculated point outside of the material. The tool moves to the necessary depth outside of the material and then plunges into the material.
The Descend to cutting level with Rapid option enables you to avoid vertical non-machining movements outside of the material performed with the working feed by direct rapid movement down to the cutting level.
![Page 118: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/118.jpg)

When this check box is selected, the tool descends from the Clearance level outside of the material directly to the cutting level (defined with the Step down parameter) using the Rapid feed. Then the horizontal movement into the material is started with the working feed.
When this check box is not selected, the tool descends from the Clearance level down to the Safety distance with Rapid movement. From the Safety distance, the tool descends down to the cutting level (defined by the Step down value) with the defined feed and starts the horizontal cutting movements into the material with the working feed.
The Descend to cutting level with Rapid check box is available only when the Approach from outside check box is selected.

Drill Recognition operation5.1
SolidCAM2008 R12 provides you with the new Drill Recognition operation that combines the power of automatic hole feature recognition and the interactive control by the user of the machining technology. This operation provides you with two significant advantages versus the current Drilling
operation:
• The Drill Recognition operation performs powerful drill feature recognition and automatic Drill geometry creation using SolidCAM AFRM module functionality.
• While the Drilling operation enables you to define only one set of Milling
Levels parameters (Upper Level, Drill Depth, Delta Depth) that is common for all the drill positions, the new Drill Recognition operation enables you to handle separate sets of Milling Levels for each drill position. The initial values of the Milling Levels sets are automatically recognized from the model and they can be edited by the user.
The Drill Recognition operation dialog box enables you to define the geometry and the technological parameters of the operation.
![Page 127: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/127.jpg)
5. Automatic Feature Recognition and Machining (AFRM)
127
Geometry definition5.1.1
SolidCAM2008 R12 enables you to define the geometry for the Drill Recognition operation using the AFRM functionality. The geometry used for the Drill Recognition operation is automatically recognized on the Target model. Therefore the Target model should be defined in the CAM-Part before you define the Drill Recognition operation.
The geometry definition is performed using the HR Drill
Geometry Selection dialog box. This dialog box provides you control over the parameters of the drill recognition and enables you to select the specific hole features that you want to machine in the current Drill Recognition operation. The hole recognition is performed on the Target model in a direction parallel to the Z-axis of the Coordinate System chosen for the operation.
The major steps of the HR Drill Geometry selection are follows:
• Choose the model configuration used for the recognition.
• Set the selection filter options (Hole type, Hole
diameter, Hole Upper level and Hole Height).
• Perform the holes recognition and generate the recognized holes tree.
• Choose from the holes tree those holes that you want to include in the operation geometry.
• See a preview of the machining sequence.
Following is a detailed explanation of the all the sections and parameters of the HR Drill Geometry Selection dialog box.

Found holes Undo/Redo
This section provides you with the Undo/Redo buttons that enable you to go back/forward to a specific choice of holes, found with a specific set of filter parameters.
Options
• Find Holes
The Find holes button performs the holes recognition and filtering of the recognized holes according to the criteria described above. The hole features matching the specified filter criteria will be displayed in the Holes
Tree list.
Actually, the holes recognition is not performed each time when you click on the Find Holes button. When the holes recognition is performed the first time for a specific Z-axis direction, the recognized holes data is stored in the database and can be used for further geometry definition. When you click on the Find
Holes button, SolidCAM retrieves the data from the database, according to the filter settings, and checks the synchronization between the data and solid model. If the data in the database is not synchronized, a new holes recognition process is performed and filtering is re-applied.

Synchronization
Synchronization in case the model changes
During the synchronization check, SolidCAM checks the correspondence between the holes included in the geometry and the updated solid model. If a mismatch between the holes location is found, SolidCAM marks this geometry as “not synchronized” and enables you to synchronize it. During the synchronization, SolidCAM updates the holes locations. If the location of a hole included in the geometry cannot be updated from the model (the hole is missing), SolidCAM excludes this hole from the geometry. If all the holes are excluded from the geometry, SolidCAM marks this geometry with an exclamation sign; such geometry requires manual editing and re-definition.
Synchronization in case of Coordinate system change
When the Coordinate System used for the geometry definition is changed, SolidCAM tries to recalculate all the hole features included in the geometry, according to the updated Coordinate system position and orientation.
When the axis of a hole, included in the geometry, is not parallel to the Z-axis of the updated Coordinate system, SolidCAM excludes this hole from the geometry. If all the holes are excluded from the geometry, SolidCAM marks this geometry with an exclamation sign; such geometry requires manual editing and re-definition.
When the parallelism between hole axis and Z-axis of the Coordinate System is preserved after the CoordSys update, SolidCAM recalculates the hole center coordinates according to the updated origin.

Selection mode
The Selection mode section enables you to set the mode of the geometry selection. The following selection modes are available:
• SolidBody. This mode enables you to perform automatic recognition of the pocket features on the picked solid body. With this mode, SolidCAM recognizes all the planar faces with the surface normal vector oriented parallel to the Z-axis of the current CoordSys. Planar faces that cannot be machined with the current CoordSys position (undercuts) are rejected from the selection. All the through pocket areas are recognized (according to the Through pocket option state).
• Face. This mode enables you to pick single planar faces. When a face is picked, SolidCAM checks the parallelism between the surface normal vector of the picked face and the positive direction of the Z-axis of the current CoordSys. If they are not parallel, the face is not selected. The undercut faces that cannot be machined with the current CoordSys are also rejected. With the Face option, the selection is working in toggle mode: the first click on a face selects it, the next click on the selected face removes it from the selection.

Helical Machining strategy6.2
SolidCAM2008 R12 HSM Module provides you with a new Helical Machining strategy. With this strategy, SolidCAM generates a number of closed profile sections of the 3D Model geometry, located at different Z-levels, similar to the Constant-Z strategy. SolidCAM then joins these sections in a continuous descending ramp in order to generate the Helical Machining tool path.
The tool path generated by the Helical Machining strategy is controlled by two main parameters:
![Page 157: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/157.jpg)

• Stepdown. This parameter defines the distance along the Z-axis between two successive Z-levels, at which the geometry sections are generated. Since the Step down is measured along the Z-axis (similar to the Constant-Z strategy), the Helical Machining strategy is suitable for steep areas machining.
• Max.Rampangle. This parameter defines the maximum angle (measured from horizontal) for ramping. The descent angle of the ramping helix will be no greater than this value.

Offset Cutting strategy6.3
In previous versions, SolidCAM was offering you the Morph Machining strategy, where the tool path is generated between two Drive curves, that define the shape of the tool path.
SolidCAM2008 R12 HSM Module provides you with an additional Offset Cutting strategy. This strategy is a particular case of the Morph
Machining strategy; the Offset Cutting
strategy enables you to generate a tool path using a single Drive curve. The tool path is generated between a Drive curve and a virtual offset curve, generated at the specified offset from the Drive curve.
The Curve section in the Drive boundary page enables you to define the Drive curve used for the tool path definition.

The Clear direction section enables you to specify the direction in which a virtual offset of the Drive curve is created. SolidCAM enables you to generate the offset in Right, Left or Both directions from the Drive curve.
The Cutting direction section enables you to determine how the machining is performed. If the Along option is chosen, the machining is performed along the drive curve. The tool path morphs between the shapes of the drive curve and the offset curve, gradually changing shape from the first drive curve to the offset curve. When the Across option is chosen, the tool path is performed across the drive curve; each cutting pass connects corresponding points on the drive curve and offset curve.

Cut order
The Cut order option enables you to define the sequence of the cuts. SolidCAM provides you with three possibilities: Standard, From Center Away and From outside to center. With the Standard option, SolidCAM performs the machining from one side of the drive surface and continues to the other side. With the From Center Away option, the machining starts from the center of the drive surface and continues outwards. With the From
outside to center option, the machining starts from the drive surface edges and continues inwards.

Partial machining8.1
SolidCAM2008 R12 offers you a new functionality that supports rough, semi-finish and finish machining of long turning parts. In long turning parts the machining of the whole geometry all at once might cause problems due to the deformation of the workpiece under the cutting tool. The new functionality provides the capability to machine the geometry partially by dividing it into several sub-geometries.
The new Partial machining option in the Modify geometry section of the Technology page of Turning Operation dialog box enables you to machine the profile in segments.
When you choose this option and click on the Data button, the Partial machining
dialog box is displayed.
The Data button is available only when the Rough or Profile option is chosen for the Work type, and the Geometry and Tool are defined.

Select profile
The Select profile section enables you to choose the chain for which the Partial machining will be used; choose the chain by the number in the combo-box. The Next profile button enables you to automatically switch to the next chain in the geometry.
First point/Second point
The First point and Second point sections enable you to define the profile segment which will be machined by the operation and the parameters of the tool approach/retreat movements.
The generated partial cutting pass is performed between the first and second points; the cutting pass direction is determined according to the Profile direction option state.
SolidCAM automatically generates the approach and retreat passes at the First and Second points according to the machining direction. In the illustration above, the approach movement will be performed at the Second
point and the retreat movement at the First point.
The approach/retreat passes consist of an arc, tangential to the partial machining geometry, at the First/Second point and a line connected to the arc. The line direction is automatically chosen according to the Tool type, Tool tip angle and Safety angle parameters.

Modify contour to avoid collision
The Modify contour to avoid collision check box enables you to perform the modification of the partial machining geometry.
When this check box is activated, SolidCAM performs the geometry modification according to the tool shape. The modification enables you to avoid the possible collisions between the tool and geometry during the machining. During the geometry modification, the machining geometry is changed in areas where the possible collisions are detected. The geometry is changed taking into account the tool shape.
The Modify contour to avoid
collision check box affects on the finish and semi-finish only, when the Profile option is chosen for the Work type. When the Rough option is chosen, the geometry modification is automatically performed, irrespective of the state of the Modify contour to
avoid collision check box.
The Show button enables you to display the machining geometry and the updated partial geometry between the First and Second points, with the tangential arcs and connected lines.

Interoperational movements8.2
In previous SolidCAM versions, all the tool movements between turning operations were performed through a position that is located outside of the CAM-Part. This means that when the cutting passes of a specific operation are completed, the tool moves to the point mentioned above and from there continues to the start position of the next operation (if tool change is not performed). Such behavior causes a number of unwanted extra tool movements.
SolidCAM2008 R12 provides you with the capability to optimize the interoperational movements between turning operations in order to shorten them.
Interoperational tool movement optimization8.2.1
When the interoperational turning tool movement optimization is activated for the current CAM-Part, the optimization is performed as described below.
When the cutting passes of a turning operation are completed, the tool moves to the operation end position. From this point the tool moves directly to the start position of the next turning operation in the shortest possible route.
![Page 228: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/228.jpg)

During this movement a check for possible gouges is performed. If a gouge is detected during the interoperational tool movement, the tool path is modified so that the gouge will be avoided.
The optimization of the interoperational tool movements is performed between two successive operations that use the same tool.

Generation of the Material boundary solid8.4
In previous versions, SolidCAM was automatically generating the updated Material boundary after each turning operation. The Material boundary, generated after a specific turning operation, was used for the automatic rest material calculation for the succeeding operation. SolidCAM was also enabling you to generate a sketch in the CAM-component of the CAM-Part assembly, containing the Material boundary after a specific operation. SolidCAM2008 R12 provides you with the additional functionality to generate a revolved solid feature that represents the Material boundary after a number of turning operations.
The generated solid body can be used as input stock for an additional CAM-Part that continues the machining, starting from this stock. This functionality is needed in case you have a turning machine and a milling machine and you want to complete a part that has both turning and milling operations.
The Generate Material boundary as solid
command is added into the right-click menu available for single operations.
The Generate Material boundary as solid
command generates a revolved feature in the CAM-component. The revolved feature is based on sketch of the Material boundary obtained after the chosen operation.
If a previously generated revolved feature already exists in the CAM-component, SolidCAM updates it to represent the Material boundary for the chosen operation.

Tool direction and imaginary tool nose8.5
SolidCAM2008 R12 enables you to define the application direction for the turning tools. In addition to the application direction definition, SolidCAM provides you with the possibility to define the imaginary nose point of the tool that will be used for the tool nose compensation; this replaces the previous Origin definition (the necessary conversion for already defined CAM-Parts in previous versions is done automatically by SolidCAM2008 R12).
The Application direction section located in the Topology page of the Part Tool Table
dialog box enables you to set the application direction for the current tool.
The first check box enables you to choose the major direction for the tool from the list. SolidCAM provides you with the following values for the major application direction.
In addition to the major application direction, SolidCAM enables you to perform the fine tuning of the application angle with the second edit box. This edit box enables you to define the value from 0° to 89°. When the upper limit is exceeded, the next major tool direction is chosen.

For example, when the 90° is chosen for the major application direction, the following possibilities (marked by circles) are available to define the imaginary nose point:
If the defined application direction (e.g. 150°) is between the major application directions (0°,90°, 180°, 270°), SolidCAM takes the defined major application direction (in this case: 90°) for the imaginary nose point definition.
The automatically generated image displays the actual location of the imaginary nose point that is chosen, relative to the tool geometry.
The Define delta from center option enables you to define the location of the imaginary nose point, by the Z- and X- delta distances from the tool radius center.

Clamp and Material boundary synchronization8.7
SolidCAM2008 R12 provides you with the functionality that enables you to establish associativity between Material boundary and Clamp and the design model; the associativity is available if the Material boundary and Clamp are defined using sketches.
To establish the associativity and obtain the possibility to perform the synchronization between the Material boundary / Clamp and design model, the sketches used for the Material boundary / Clamp definition should each contain one closed contour, marked as non-construction geometry.
When Material boundary / Clamp are defined on sketches (the 2D Boundary mode of the Material boundary definition), SolidCAM saves the name of the sketch and associates it to the defined geometry; the sketch name will be used during the synchronization.
Synchronization
The Synchronize command is available in the right-click menu on the CAM-Part header. This command enables you to perform the synchronization of the Material boundary / Clamp geometries.
During the synchronization SolidCAM retrieves the relevant sketch, by its name saved in the geometry, and generates the chain for the closed contour, retrieved from this sketch.
If the relevant sketch is not found, the Material
boundary / Clamp geometry remains the same; the synchronization is not performed.
If the chain suitable for the Material boundary / Clamp cannot be created, SolidCAM leaves the Material boundary / Clamp unchanged; a warning message is displayed. In this case you have to repair the sketches and perform the synchronization again.
![Page 237: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/237.jpg)

237
When new suitable chains are created, SolidCAM checks the Clamp chain and Material
boundary chain for common boundaries or intersection (since in SolidCAM the clamp and material boundary must either intersect or have a common boundary). If common boundaries or intersection are found, SolidCAM substitutes the current Clamp and Material boundary with the new chains; if there are no common boundaries or intersection, the Material boundary / Clamp geometry remains unchanged (synchronization is not performed); a warning message is displayed. In this case you have to repair the sketches and perform the synchronization again.

Envelope calculation enhancements8.8
SolidCAM2008 R12 provides you with a new enhanced method for the envelope calculation. In the new method, SolidCAM determines the type of the model faces used for the envelope calculation. For regular model faces, like cylinder and cone, SolidCAM uses an analytical algorithm which generates envelope segments relevant for this type of face. For complex B-spline surfaces, SolidCAM generates the envelope segment related to this surface using the facetted model of the surface; the facets are generated according to the Facet tolerance parameter specified in the Part Data dialog box.
The Facet tolerance parameter defines the accuracy of triangulation; smaller tolerance values increase the precision of the envelope generation but increase the envelope calculation time.

Turning geometry definition by picking model entities8.9
SolidCAM2008 R12 provides you with the capability to define the geometry for turning operations, on the generated envelope/section, by picking the model entities such as faces, edges and vertices. When model entities are picked, SolidCAM automatically defines the geometry on the envelope/section segment corresponding to the selected model elements.
With this method of the turning geometry definition, SolidCAM enables you to choose two entities (faces, edges, vertices, origin and sketch points) on the solid model. The selected entities are projected on the envelope/section in the defined direction. The envelope/section segment, enclosed between the points determined by the model entities projection, is chosen as the geometry chain.
The Define button, in the Geometry page of the operation dialog box of the Turning, Grooving and Threading operations has two options:
• On Profile. This option enables you to define the turning geometry by wireframe geometry selection using the Geometry Edit dialog box. This is the default option that was available till now.

Associativity and Geometry Synchronization8.9.1
When the geometry is defined, SolidCAM saves the tags of the selected model entities; these tags are used to perform the geometry synchronization in case of model changes.
When the model is changed, SolidCAM enables you to perform the synchronization of the Target model. During the Target model synchronization, SolidCAM regenerates the envelope/section.
During the synchronization check for the geometries, SolidCAM compares the geometry with the regenerated envelope/section; if they are not exactly the same, SolidCAM enables you to perform the synchronization. During the synchronization, SolidCAM determines the model entities used for the geometry definition according to the saved tags. With these entities, SolidCAM automatically determines the envelope/section segment and updates the geometry according to the regenerated envelope/section.

SolidCAM2008 R12 provides you with a new type of CAM-Parts named Mill-Turn. This type is intended for the programming of Mill-Turn CNC machines, especially 5-axes milling CNC machines with turning capabilities (e.g. DMU FD-series of DMG).
This Mill-Turn functionality provides you with a number of significant advantages compared to the current Turn-Mill type:
• The Mill-Turn module provides you with the full functionality of the Coordinate
System definition, identical to the SolidCAM Milling.
• The Turning mode of the Coordinate System enables you to use the same coordinate system for milling as well as for turning without additional definition.
• In stock definition, you can define the Stock in the same manner as in SolidCAM Milling and the Material boundary in the same manner as in SolidCAM Turning.
• The Mill-Turn module enables you to perform Milling, Turning and Mill-Turn operations with the same post-processor.
• Using the Mill-Turn module, you do not need to learn new rules; you just work in regular milling and can add turning operations as needed.
It is recommended to use the new Mill-Turn type for all Mill-Turn machines (instead of the current Turn-Mill type) and for Turning machines where you need support for a second Coordinate System for turning. All current parts of Turning or Turn-Mill type can be automatically converted by SolidCAM2008 R12 to Mill-Turn type.

The Mill-Turn Part data dialog box is displayed. This dialog box enables you to choose the CNC-machine controller, define coordinate system, stock/material boundary, target etc.
CNC-controller definition9.1.1
Choosing CNC-controller is the first step in the Mill-Turn CAM-Part definition. The CNC-Controller edit box displays all the controllers suitable for Mill-Turn.
The new MILL_&_TURN_FULL type of CNC-Controllers is added to the controller definition file (MAC-file). The machine_type = MILL_&_TURN_FULL command in the MAC-file enables you to turn on the support of Mill-Turn machines.

9.1.2 Coordinate System definition
SolidCAM2008 R12 Mill-Turn module enables you to define the coordinate systems in the same manner as in SolidCAM Milling.
The Machine Coordinate system #1 (Position #1) can be used for turning operations as well as for all the milling operations. In the Turning mode, SolidCAM uses the Turning
Coordinate System created by rotating of the Machine Coordinate System #1 (Position #1) around the Z-axis. The turn_home_x and turn_home_y parameters in the controller definition file (MAC-file) define the orientation of the X- and Y-axes of the Turning Coordinate System respectively relative to the Machine Coordinate System #1 (Position #1):
For example:
turn_home_x = 0.0 1.0 0.0
turn_home_y = -1.0 0.0 0.0
With such parameters definition, the X-axis of the Turning Coordinate System is codirectional to the Y-axis of the Machine Coordinate System #1 (Position #1); the Y-axis is codirectional to the negative direction of the X-axis of the Machine Coordinate System #1 (Position #1).
The Turning Coordinate system is used for the definition of the turning operations, Material boundary and Clamp.
If the turn_home_x and turn_home_y variables are not specified in the controller definition file, the axes of the Turning Coordinate System are collinear to the respective axes of the Milling Coordinate System
(turn_home_x = 1.0 0.0 0.0; turn_home_y = 0.0 1.0 0.0)

CoordSys Data
In the Mill-Turn module, facial and radial machining is performed using the same Coordinate System. But since the part levels used for facial milling are measured along the Z-axis whereas those used for radial milling are measured around the Z-axis, the CoordSys data must be defined separately.
The Facial and Radial tabs are added into the CoordSys Data dialog box so that two different sets of levels can be defined.
The Facial tab contains a set of machining levels describing the planes parallel to the XY-plane and located along the Z-axis.

Stock and Machining boundary9.1.3
SolidCAM enables you to define both of the Stock and Material boundary for Mill-Turn CAM-Parts. The stock definition process is similar to the stock definition in SolidCAM Milling. The Material boundary definition process is similar to the Material boundary definition in SolidCAM Turning. The Turning Coordinate System (see topic 9.1.2) is used for the Material boundary definition.
The Material boundary definition is obligatory in order to enable the use of turning operations in the Mill-Turn CAM-Part. For the Mill-Turn CAM-Parts containing only milling operations the Stock and Material boundary definition is optional.
The defined stock model is used in the SolidVerify simulation mode. If the stock model is absent, and only the Material boundary is defined, it is used instead of the stock for the SolidVerify simulation.
Clamp definition9.1.4
SolidCAM enables you to define the clamp (the Main Spindle/Back Spindle buttons) for Mill-Turn CAM-Parts. The Clamp definition process is similar to the Clamp definition in SolidCAM Turning. The Turning Coordinate System (see topic 9.1.2) is used for the Clamp definition.
The Clamp definition is obligatory in order to enable the use of turning operations in the Mill-Turn CAM-Part. For the Mill-Turn CAM-Parts containing only milling operations the Clamp definition is optional.
Optionally, SolidCAM enables you to define the Fixture, similar to Fixture definition in SolidCAM Milling. During the SolidVerify simulation, the Clamp is displayed for Turning operations; for Milling operations, the Clamp is hidden and the Fixture is displayed.
Target definition9.1.5
SolidCAM enables you to define the Target model for Mill-Turn CAM-Parts. The Target model definition process is similar to the Target model definition in SolidCAM Turning.
The Target section of the Mill-Turn Part Data dialog box, enables you to choose Envelope or Section to be generated during the Target model definition. When the None option is chosen, SolidCAM does not perform the Section/Envelope generation.
![Page 252: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/252.jpg)

Existing CAM-Parts conversion9.2
SolidCAM2008 R12 enables you to convert existing CAM-Parts of the Milling, Turning and Turn-Mill type into the Mill-Turn type. To convert a CAM-Part you have to choose in the Part data dialog box a new Mill-Turn CNC-Controller.
The following message is displayed informing you about the CAM-Part conversion. The message enables you to choose one of the following options:
• Continue. With this option, the CAM-Part will be converted to the chosen Mill-Turn CNC-Controller.
• Backup&Continue. With this option a backup copy of the CAM-Part is created and the CAM-Part is converted to the Mill-Turn type.
• Exit. This option aborts the conversion.
Conversion of Milling CAM-Parts
During the conversion of Milling CAM-Parts into Mill-Turn, SolidCAM keeps all the Machine Coordinates Systems and related positions existing in the initial Milling CAM-Part preserving their location and orientation unchanged in order to provide seamless conversion of the geometries and operations. In addition to this, SolidCAM automatically generates the Turning Coordinate System. It is created according to the position and orientation of the Machine Coordinate System #1 (Position #1) taking into account the turn_home_x and turn_home_y parameters defined in the controller definition file (MAC-file).
Conversion of Turning CAM-Parts
During the conversion of Turning CAM-Parts into Mill-Turn, SolidCAM automatically generates the Machine Coordinate System #1 (Position #1) according to the position of the Turning Coordinate System. The axes orientation is defined according to the turn_home_x and turn_home_y parameters.
All the turning operations defined in the initial Turning CAM-Part are kept unchanged.
![Page 253: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/253.jpg)
Mill-Turn
253
Conversion of Turn-Mill CAM-Parts
During the conversion of the Turn-Mill CAM-Parts, SolidCAM considers the Machine Coordinate System #1 (Position #1) of the Turn-Mill CAM-Part as Turning Coordinate
System and automatically generates the Machine Coordinate System #1 (Position #1) according to the position of the Turning Coordinate System. The axes orientation is defined according to the turn_home_x and turn_home_y parameters.
All other Machine Coordinate Systems defined in the Turn-Mill CAM-Part (Mac #2 used for sim. 4-axis operations, Mac #3 used for indexial milling operations and Mac #4 used for milling operations in back spindle) are converted into positions of the Machine Coordinate System #1.
All the operations and geometries are converted and assigned to the relevant positions (converted from the Machining Coordinate Systems of the initial CAM-Part).
SolidCAM does not enable you to convert into Mill-Turn the Turn-Mill CAM-Parts defined using the Projections mode of the Coordinate System definition.
Conversion of Mill-Turn CAM-Parts from one CNC Machine to another
During the conversion of a Mill-Turn CAM-Part from one CNC Machine to another, SolidCAM converts the Machine Coordinate System #1, preserving the orientation of the Turning Coordinate System defined in the initial CAM-Part, according to the values of the turn_home_x and turn_home_y parameters specified in the controller definition file (MAC-file).
All the operations and geometries are converted and assigned to the relevant positions (converted from the Machining Coordinate Systems of the initial CAM-Part).
![Page 254: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/254.jpg)
254
Additional Turning Coordinate Systems9.3
SolidCAM enables you to define a number of Turning Coordinate Systems that can be used for the machining of parts using the back spindle or for the machining of parts from both sides, using the main spindle.
When a new Machine Coordinate System is defined according to the conditions listed below, the Turning Coordinate System is automatically created for this Machine Coordinate
System according to the values of the turn_home_x and turn_home_y parameters specified in the controller definition file (MAC-file). The following conditions should be maintained:
• The Z-axis of the additional Machine Coordinate System should be collinear to the Z-axis of the Machine Coordinate System #1 (Position #1); it can be the same or in the opposite direction.
• The origin of the additional Machine Coordinate System should be located on the Z-axis of the Machine Coordinate System #1 (Position #1).
In the illustration above the Turning Coordinate System will be created for the Machine Coordinate System #2, since the origin of this Coordinate System is located on the Z-axis of the Machine Coordinate System #1 (Position #1) and the Z-axes are collinear. The Turning Coordinate System is created according to the turn_home_x and turn_home_y parameters.

If the additional Machine Coordinate System is intended to be used for turning, the Back Clamp should be defined. All the turning operations defined with this Machine Coordinate System will use the Back Clamp.
The additional Machine Coordinate System can be used to perform the operations using the Back Spindle. In this case the Back Clamp describes the geometry of the clamping device mounted on the back spindle.

Pre-processor customization9.4
As described before, any Milling, Turning or Turn-Mill pre-processor file (MAC file) can be converted into Mill-Turn by setting the machine_type parameter to MILL_&_TURN_FULL. The turn_home_x and turn_home_y parameters should be defined to set the orientation of the Turning Coordinate System.
In addition to these parameters, the num_axes = 5 parameter should be defined in order to provide you with all the possibilities of 5-axis machining.
In Turning and Turn-Mill pre-processors a number of parameters should be defined to provide you with the support of the indexial 5-axis milling. For example, the _5x_rotary_axes and tilt_axis_dir parameters should be defined. The _5x_rotary_axes
parameter defines the linear axes which provides you with the possibilities to perform rotation around them. The tilt_axis_dir parameter enables you to specify the direction in which the tilting is performed.
In Milling pre-processors, a number of the parameters affecting on the turning should be defined. For example the turn_common_proc parameter which enables you to control the generation of the common geometric points procedure for several cycles and the turning_cycle / groove_cycle parameters which determine whether the machine has a turning /grooving cycles.
![Page 258: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/258.jpg)
258
Post-processor customization9.5
SolidCAM enables you to adapt any Milling, Turning or Turn-Mill post-processor for Mill-
Turn Machine.
Milling post-processor adaptation9.5.1
To adapt a Milling post-processor for Mill-Turn, the Turning functions should be added to the post-processor. For example, to add support for turning cycles in the post-processor, the @turning function should be added. The @turn_change_tool function should be added to support changing of turning tools.
For more information about turning functions, refer to GPPTool User Guide.
Some of the functions used in Mill-Turn post-processors (e.g @line, @rapid_move or @arc) are common for Milling and Turning. In this case, you can customize the GCode output for this functions according to the machining type (either milling or turning).
In the example below different GCode output is performed for milling and turning operations in @line function.
;-------------------@linegcode = 1{nb,[‘G’gcode]}if job_machine_type eq milling {[‘ X’xpos:coord_f], [‘ Y’ypos],[‘ Z’zpos], [‘ F’feed]}else ; turning {[‘ X’xpos], [‘ Z’zpos], [‘ F’feed]}endifendp;-------------------
In the example above different formats are used for the xpos output in Milling and Turning. For Milling, the coord_f format is used, for Turning, the default xpos_f format is used.
![Page 259: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/259.jpg)
Mill-Turn
259
Turning post-processor adaptation9.5.2
To adapt a Turning post-processor for Mill-Turn, the Milling functions should be added to the post-processor. For example, to add support for 4- and 5-axis output in GCode, the @line_4x and @line_5x functions should be added. The @home_data / @tmatrix
functions can be modified or added to support indexial 5-axis machining.
For more information about Milling functions, refer to GPPTool User Guide.
Some of the functions used in Mill-Turn post-processors (e.g @line, @rapid_move or @arc) are common for Milling and Turning. In this case, you can customize the GCode output for this functions according to the machining type (either milling or turning).
In the example below, different GCode output is performed for milling and turning operations in @arc function.
@arc if job_machine_type eq milling call @arc_mill else ;turning if arc_direction eq CCW then gcode = 3 else ; CW gcode = 2 endif {nb, [‘G’gcode] ‘ X’xend:xpos_f ‘ Z’zend}
if arc_size >= 180 then radius = -radius endif {‘ R’radius, [‘ F’feed]} endifendp
;-------------------
@arc_mill skipline=true ;-- arc plane -- if change(arc_plane) then if arc_plane eq XY then gcode = 17 endif if arc_plane eq YZ then gcode = 18 endif
![Page 260: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/260.jpg)
260
if arc_plane eq ZX then gcode = 19 endif {nb,’G’gcode, ‘ ‘} endif
if arc_direction eq CCW then gcode = 3 else ; CW gcode = 2 endif if change(gcode) then {nb,’G’gcode} else {nb,’ ‘} endif {[‘ X’xpos:coord_f] [‘ Y’ypos] [‘ Z’zpos]}
if arc_size eq 360 then if arc_plane eq XY then {‘ I’xcenter_rel, ‘ J’ycenter_rel} endif if arc_plane eq YZ then {‘ J’xcenter_rel, ‘ K’ycenter_rel} endif if arc_plane eq ZX then {‘ K’xcenter_rel, ‘ I’ycenter_rel} endif else if arc_size >= 180 then radius = -radius endif {‘ R’radius} endifendp;-------------------
In the example above, the @arc function contains the condition which enables you to customize the GCode output for Milling and Turning. The @arc function defines the format for Turning GCode output. For Milling, the @arc_mill function is called from the @arc function.
The method of the postprocessor programming described above, enables you to modify the @arc function in a Turning post-processor by adding conditions that define different actions for milling and turning. The @arc_mill function can be obtained by copying the contents of the @arc function from a Milling post-processor
![Page 261: What is New in SolidCAM](https://reader031.vdocuments.site/reader031/viewer/2022013110/54689705b4af9fcd688b49a0/html5/thumbnails/261.jpg)
Mill-Turn
261
Turn-Mill post-processor adaptation9.5.3
To adapt a Turn-Mill post-processor for Mill-Turn, the @home_data / @tmatrix functions should be modified in order to support work with Coordinate Systems in Mill-Turn.
The example below illustrates the @tmatrix function from a Turn-Mill post-processor. This function provides you with different handling for different Machine Coordinate Systems. For example, for the Machine Coordinate System #2, the @tmatrix function enables you to orient the tool to perform the simultaneous 4-axis milling.
@tmatrixif job_machine_type eq milling if part_home_number <> pre_part_home_number if mac_number eq 1 {NB,’#101=’rotate_angle_z} {nb,’ G91 G28 X0’} {nb,’G90’} if rot_axis_type eq axis4_none {nb,’G69’} {nb,’M212’} {nb,’G0 B0.

The @tmatrix of Mill-Turn post-processor provides you with the same handling for Positions of all the Machine Coordinate Systems. This function defines the Position location and orientation relative to the Machine Coordinate System.
@tmatrix {nb, ‘G69’} {nb, ‘G49’} {nb, ‘G91 G28 X0’} {nb, ‘G28 Y0 Z0’} {nb, ‘G90’} {nb,’M108’} {nb,’G0 B’rotate_angle_y,’ ‘chuck_axis rotate_angle_z} {nb,’M107’} {nb,’G68 X’,shift_x, ‘ Y’shift_y, ‘ Z’shift_z, ‘ I0. J1. K0. R’rotate_angle_y}endp

Geometry wrapped around axes for 4-axis machining9.6
In the previous Turn-Mill module, the definition of geometry for 4-axis machining required an additional Coordinate System suitable for radial milling. The Mill-Turn functionality enables you to perform radial milling using the same Coordinate System as for facial milling.
For Profile geometry, the Wrapping mode of the geometry definition in the Geometry Edit dialog box offers you the choice of axis around which the geometry is wrapped.

268
The Auto mode enables you to define the Upper and Lower profiles by picking on the solid model face.
When the face is picked, SolidCAM automatically determines the closed loop of the picked face and all the faces adjacent to this loop.
The first chain is defined automatically on the closed loop of the selected face. The second chain is defined automatically on the opposite edges of the faces adjacent to the picked face loop.
If only one loop is determined for the face, SolidCAM automatically defines the geometry chain along the edges of this loop. If the picked face contains more than one loop, they are highlighted; you then have to choose the necessary loop for the chain definition by picking and the chosen chain is highlighted.
The Reject button enables you to delete the chains defined by faces picking.
Defining the Connect points
Connect points are the pair of points situated on the Upper and Lower
profiles of the 4-Axis geometry. The line connecting these points provides smooth transition of the profiles.
When both of the Upper and Lower profiles are defined, SolidCAM automatically generates a number of connect points pairs on the profiles and connects them.

SolidVerify support in Machine Simulation11.1
In previous SolidCAM versions, the Machine Simulation mode provided you with the capability to simulate the tool path and CNC machine motions during the machining. SolidCAM2008 R12 provides you with an additional capability to perform the solid verification of the material cutting process using the SolidVerify mode, integrated into the Machine Simulation. With this functionality, SolidCAM enables you to display the stock model and perform the simulation by dynamic subtraction of the tool solid model (using solid Boolean operations) from the stock solid model.
The Full Machine verification option is added to the Machine Simulation page of the SolidCAM Settings dialog box.
When this option is activated, the solid verification is performed in the Machine simulation mode.

Machine Simulation for Turning, Turn-Mill and Mill-Turn11.2
SolidCAM2008 R12 provides you with the support of the Machine Simulation mode for Turning, Turn-Mill and Mill-Turn modules.
With this functionality turning operations can be verified as well as milling operations.
For more explanations on the CNC-Machine definition for the Machine Simulation refer to SolidCAM Turning User Guide.

Fixtures support within Machine Simulation11.3
SolidCAM2008 R12 enables you to display the fixtures defined for the CAM-Part in the Machine Simulation.
To use this functionality, you have to add the fixture into the CNC-Machine definition.
Since the fixture is clamping the workpiece on the CNC-Machine table and these components are always moving together, all the coordinate transformations are the same for workpiece and fixture. Therefore you do not need to define a separate coordinate transformation for the fixture; you can use the existing transformation of the workpiece. The fixture definition should be added to the CNC-Machine definition tree under the Workpiece transform.
In the CNC machine definition tree, right click on the workpiece_transform coordinate transformation item and choose the Add
Geometry command from the menu.

This command enables you to define the geometry of the fixture.
The Element properties dialog box is displayed.
Define the ID of the fixture geometry. Use the built-in name Fixture for the ID definition. This name is hard-coded in SolidCAM and cannot be changed.
Click on the Browse button and choose the fixture.stl file, containing the fixture model, from the CNC-Machine folder. During the specific part simulation this file will be overwritten with the STL-file of the actual fixture used in the CAM-Part.
If you have no fixture.stl file, you can create it by copying and renaming any other *.stl file. In this case the content of the STL-file is not important, because it will be overwritten with the relevant data during the simulation for every CAM-Part.

Solving self-intersections and noise problems in solid 11.4verification
Checking and fixing self-intersections11.4.1
Many problems occur in solid verification (SolidVerify, RapidVerify and Machine
simulation modes) if the solids used (Machined Stock model, Target model and Fixture) are not topologically valid. In particular, solid verification is likely to encounter problems with solids that contain self-intersections – that is, solids which contain pairs of polygons which overlap each other, or individual polygons whose edges cross.
Self-intersections can be encountered in the following cases:
• The model (Stock, Target or Fixture) is based on a SolidWorks assembly or sub-assembly containing a number of components.
• The model (Stock, Target or Fixture) is based on a SolidWorks part containing a number of disjointed solid bodies.
• The model (Stock, Target or Fixture) is based on a SolidWorks part with corrupted geometry (gaps, self-intersections etc.).
Such self-intersection problems can be solved during the Stock/Target/Fixture model definition.
The Check and fix button in the Self-intersections section of the
Stock model/Target model/Fixture dialog box enables you to check the model for self-intersections and, if they are found, fix them.
When the self-intersections are detected, the following message is displayed; confirm it with the Yes button to fix the self-intersections.
Note that the process of self-intersection fixing can take a long time to complete, depending on the complexity of the model.

Rounding of input data11.4.2
During the facetting of Stock and Target models, the coordinates of facets generated by SolidCAM are often calculated as numbers of the float type with many digits after the point. These numbers cause problems during the SolidVerify simulation, such as self-intersections and gaps in model.
SolidCAM2008 R12 provides you with a new functionality that enables you to avoid such problems. The Automatically remove noise from input data check box added to the Updated Stock & SolidVerify page of the Part Settings dialog box enables you use a smart rounding algorithm that removes the noise in facet coordinates so that the model is displayed properly.
Note that the process of rounding can take a long time to complete.
