Directory

Specify the location of the CAM-Part. The default directory is theSolidCAM user directory (dened in the SolidCAM Settings). You canenter the path or use the Browsebutton to dene the location.

The Use Drawing file directoryoption enables you to create CAM-Parts automatically in the same folder where the original CAD Modelis located.

CAM-Part name

Enter a name for the CAM-Part. You can give any name to identifyyour machining project. By default SolidCAM uses the name of thedesign model.

Model name

This eld shows the name and the location of the SolidWorks designmodel that you are using for the CAM-Part denition. The name is,by default, the name of the active SolidWorks document. With the

Browsebutton you can choose any other SolidWorks document to

dene the CAM-Part. In this case, the chosen SolidWorks documentis loaded into SolidWorks.

Every time the CAM-Part is opened, SolidCAMautomatically checks the correspondence of the dates ofthe CAM-Part and the original SolidWorks design model.

When the date of the original SolidWorks model is laterthan the date of the CAM-Part creation, this means thatthe SolidWorks original model has been updated. Youcan then replace the SolidWorks design model on whichthe CAM-Part is based with the updated SolidWorksdesign model.


19/13819


3. Confirm the CAM-Part creation

After the Directory, CAM-Part nameand Model name are dened, clickon the OK button to conrm theCAM-Part creation. The CAM-Part

is dened and its structure is created.The Turning Part datadialog box isdisplayed.

The structure of the CAM-Part

The CAM-Part includes the datales represented on the illustrationthat displays the data included in theCAM-Part named Turning.

The le Turning.prt is located in

the SolidCAM User directory. TheTurning subdirectory contains all thedata generated for the CAM-Part.

SolidCAM copies the original SolidWorks model to the Turninsubdirectory and creates a SolidWorks assembly that has the samname as the CAM-Part (Turning.sldasm). There are two componen

in this assembly:

DesignModel.sldprt- the copy of the SolidWorks model le.

CAM.sldprt- the le that contains SolidCAM Coordinate System datand geometry data.

The SolidCAM CAM-Part uses the assembly environment oSolidWorks. This enables you to create auxiliary geometries (e.gsketches) without making changes in the original design model. Yocan also insert some additional components into the assembly lsuch as stock model, CNC machine table, clamping and other toolinelements.

Turning Operations 3


36/138


36

SolidCAM enables you to perform the following types of turning operations.

The turning geometry has to be located in the ZX planein the Z+region and can be dened directlyon the solid model.

Turning Operation

This operation enables you to turn a longitudinal or a faceprole. The resulting tool path can either use the turning cyclesof the CNC machine, if they exist, or it could generate all thetool movements. In case the tool movements are generatedby the program, then the minimum tool movements length isgenerated taking into account the material boundary at the start

of the particular operation. The prole geometry is adjusted

automatically by the program, if needed, because of the toolshape, to avoid gouging the material.

37/13837

3. Turning Operation

Grooving Operation

This operation enables you to perform a groove either on alongitudinal geometry (internal or external) or a face geometry.

The resulting tool path can either use a single machine cycle,generate all the tool movements (G0, G1) or generate several

machine cycles.

Drilling Operation

This operation enables you to perform a drilling action at the

rotation axis. There is no geometry denition for this type ofoperation since it is enough to dene the drill start and endpositions.

Threading Operation

This operation enables you to perform a thread. The threadcould be either longitudinal (internal or external) or facial. Thisoperation can be used at present only if the CNC machine

has a thread cycle. SolidCAM will output the tool path for thethread exactly with the same length as the dened geometry

without doing any checks for material collision.

For a more detailed explanation on the turning operations, refer to the SolidCAM Turning UserGuide.
