1. Introduction

GGCad is a software for g-code ( or iso ) generation. It is designed to be userfriendly. Its simplicity, compared to other software, renders it indispensable.You will control it fastly either in its CAD mode (Computer aided design) or in

its CAM mode (Computer aided manufacturing).

With its advanced CAD module, GGCad offers you traditional drawing tools thatyou can find in most of industrial softwares. You will thus be able to drawdifferent shapes such as points, lines, circles, arcs, ellipses, text and splines.Moreover, you will have the transformation tools such as rotation, symmetry,scale, translation. Its flexibility will allow your drawings to be managed easilyand rapidly.

With its CAM module, you are able to create simple tool paths as well ascomplex tool paths (contours and pocketing). Its importing and exportingcapabilities, such as DXF and HPGL, allow you to work on your files that are

already designed.

GGCad has support for any type of font and writing, left to right, right to left aswell as Asian fonts.

2. Interface

The user interface is organised in three parts. On the top left hand corner, thereis a tree that represents levels, shapes and tool paths. On the bottom left handcorner, a property window gives access to level and shape parameters. Theright side of the screen is the space designed for drawing.

8. DXF and HPGL Post-processor

9. Shapes

Each shape has its own properties. It has a starting point and an ending point.The starting point is visualised with asmallred square. The circle,however, is aparticular case where its starting point will always be the extreme left point.

The direction can be reversed with the icon

The icon displays the process direction arrows.

For each object, there exist thepossibility to specify code before Z movement[Pre-command] and code after movement [Post-command].

Line: Point 1: starting coordinates.

Point 2: ending coordinates. Length: line length. Angle: line angle with the horizontal line. Fluting in: to bring down the tool to the tool path height along a

defined distance.

GGCad 13/34

7/29/2019 ggcad.1.5.4.en

14/34

Fluting out: Like fluting in but bringing up the tool.In the previous example, the tool goes down on 10 mm, works at thetool path height, then goes up for 10 mm.

Point drill:

The operation can be a drilling, right end taping,

boring or null. The pause is the time the tool isleft down in the material. The back position is theposition the tool is lifted to remove shaving.

Arc Centre: centre coordinates Point 1: start coordinates Point 2: end coordinates Radius: arc radius Rotation: rotation direction between points 1 et 2

Ellipse Minor : minor axe Major: major axe Rotation: process direction

Circle Centre : centre coordinates Radius : arc radius Rotation : process direction

Curve Type: algorithm used to draw the curve

Pocketing tool path Diameter: tool diameter Engagement: flute over pass ( ex : a 3 mm flute, with an engagement

of 2.8 mm = over pass of 0.2 mm ) Outer edge: to generate contours Force clipping algorithm: see chapter 15 Process outers first: by default, it starts pocketing then the outers.

Generally, better resultsare obtained. This feature allows to start withouters first.

Pocketing tool path with island selection.Same as pocketing tool path. It specifies islands if automatic detectionfails.

Outside contour tool path Offset plasma starting: the job starts next to the path Direction: to set the direction, clockwise or counter clockwise.

Inside contour tool path.

Same as outside but inside instead.

10. My first project

Your first document is made of an empty level. Levels and shapes can berenamed by selecting them, clicking with right mouse button or pressing [F2]key.

Each level represents a job space, with its own parameters. The tree representsthe levels and shapes list.

When generating G-Code, the post-processor willprocess levels and shapes in a sequential order. In theleft example, the orders will be processed as: line1 line2 line3 line4 circle1.

Lines are coded with [Dfaut1] level properties. Thecircle is coded with [Dfaut2] level properties.

Level properties are :

Drawing colours

Level visible or not

Level will be generated or not

Number or name of tool

Feed rate

Plung rate

Final deep level

Max tool height in material

Z job position will start from this value

Spindle rotation speed

Spindle direction

Cooling: none, flood coolant, mist cooling

Constant velocity

Tool will be left in low position during this time

Lock level edition

Tabs are created on closed figures to let theobject attached to its support. For exampleto avoid it to be aspired by the vacuum.

GGCad 15/34

7/29/2019 ggcad.1.5.4.en

16/34

The software philosophy is very simple. Draw a line: it is generated. Toseparate drafting and machining, you can block generation of the level with the[Generate] property. In previous example, if in [Default1], the [Generate]property is unchecked, only Circle1 will be generated.

Properties for the tool can be manually set, or by means of the tool database. Ifa tool from the database is selected, [Feed rate], [Plung rate], [Max pass],[Spindle speed] fields will be automatically modified.

11. Tools database

First column is used to select tools to be deleted. [Name] column is the toolname which must be unique. Column [] stores the tool number. Thisnumberwhich will be generated by the post-processor. Column [] gives the tooldiameter. Column [Engagement] stores the max tool width which will be insidein the material. Example, if the diameter is 3 mm, and the engagement 2.8mm, the tool will pass over 0.2 mm from previous path between two parallelmovements.

12. Free drawing

To manufacture a drawing withoutusing tool path functions, do notforget to set the shapes' direction

in the same way. By clicking in theicon , arrows that show theprocess direction will be

displayed. When constructing aform, shapes' direction can beopposed. To get the sameorientation, use the tool [Organisepath] It will set all the shapeswith the same direction.

After using it, the arrows show thatshapes have the same direction.Using [Reverse path], all directions

are reversed.

Blue arrows shows starting shapes,red arrows end shapes.

13. Pocketing tool path

Tool creation through menu [Tools][Tools database].

Create a new document. Draw a square. Size does not matter. Uncheck the[Generate] level property. Create a new level. Select tool [6 mm wood]. Clickon [Pocketing path] and click on the square.

14. Text path

In order to process a created text with tool path functions, the texthas to be converted in curves with the tool [Convert to curves].

15. Pocketing tool path with island selection

Pocketing tool path uses a simple algorithm to detect island. It will as wellremove overlapped islands.

In the left example, the orange island has beenremoved. To process it, you just need to create atool path for this orange island.

Another example: in thiscase, the algorithm removesthe orange island. To forcethe selection of the orangeisland, use the [Pocketingtool path with islandselection] tool.

Click on the exterior contour, then click on a shape of both islands with the

[Control] key pressed on. Then click anywhere else in the document. Bothislands are processed.

16. Contour path

To process a contour path, select the appropriate tool. Outside or inside, andclick on a closed figure.

To remove burrs due to

plasma arc starting, adda plasma start offset.An arc or a line isautomatically added.

If the clipping algorithm does not display anything, use the [Force clippingalgorithm] property.

Left example shows a 24 mm width square. With a 18 mmdiameter flute, offsetting is not created (overlappingdetection).

Forcing the algorithm will generate the tool path..

17. Document

Project menu allows several transformations on the whole document :

Offset the document: If shapes are not centred in the document, this toolallows centring of all shapes with an offset added around.

Change the document size : Allows to change the document size. Shapes willbe computed with the new scale.

Rotate the document: to rotate all shapes. For example, to permute X and Yaxes, you just need to rotate the document to 90.

Horizontal mirror : reverse the document upside down.

Vertical mirror : reverse the document left to right.

20. External tools

The menu [Tools][External tools] opens the dialogue box to manage theexternal tools. It will create menus to access directly to other programs throughGGCad.

GGCad creates automatically a shortcut to open the generated file. In theprevious example, a shortcut to CncSimulator is created to be runned through amenu in GGCad.

The {out} code will be replaced by the generated output file path. The {ggd}code will be replaced by the currently edited file.

Example :

A program [cnc.exe] is opened with the cnc file as argument.

Column [File]: c:\program files\cnc\cnc.exe

Column [Arguments]: {out}

22. File import

Coordinates file

Open the dialogue box to import a coordinates file. The import can add

coordinates to the document as a list of points, or as a curve (default algorithm

used is Polygon). You can change it through the properties window. You canspecify whether the curve is an open curve or a closed curve.The file is a text file formatted as follows: each line is made of the Xcoordinates, a separator, Y coordinates. If the separator is the tabulation, justselect [Tabulation], or specify another separator by choosing [Other]. ex:

1.00006;0.001340.99804;0.002000.99260;0.003720.98401;0.005940.97220;0.008660.95749;0.01168

23. 4th axe

Cylinder engraving

To engrave on a cylinder, simply untie the surface of the cylinder on thedocument. On the document property window, a button [Cylindrical axe] allowsto compute the perimeter and set it to the axe. Perimeter = diameter*2*PI.

In the post-processor, change the axe name to the one chosen : example [Y] in[A]

The post-processor will replace [Y] with [A]. Example :

G1 Z-1

X20.1745 A230.0282

X20.1745 A239.7648

X17.457 A233.4678

Multiple faces

To work on a multiple face object, the 4th

axe has to be declared in the document

properties, [4th

Axe name]. Set thediameter which is materialised by thecircle that is around the object. Theorange circle shows the circle made by theobject when rotating.

GGCad 26/34

7/29/2019 ggcad.1.5.4.en

27/34

For a squared or rectangle object, the diameter ofthe circle is the diagonal length.

To operate a rotation, set the [4th axe angle]property in the level properties. The angle is indegrees. The post-processor will move the axe insafe position before processing the level.

Be careful with the tool heightand the height reference. Itmay end-up with a tool crash.

24. Special menu

Airfoil file

Open the dialogue ox to import an airfoil. You can choose the profile in the list,or specify a new one. Next just enter the chord length of the wing. If youspecify a new file, it will be transferred into the database. The database islocated in the folder [c:\Program Files\ggcad\airfoils]. Each airfoil is stored in atext file. First line contents the airfoil description. Then each line contains the Xcoordinate, a space, the Y coordinate. The coordinates are computed in the file

to have a chord of 1.

Following is the modified g-code mapping file :

G0 = "G00" // rapid motion

G1 = "G01" // linear motion

G2 = "G02" // CW circular motion

G3 = "G03" // CCW circular motion

G4 = "G04" // Dwell

G73 = "G73" // Drilling Cycle with Chip BreakingG81 = "G81" // Drilling

G82 = "G82" // Drilling Cycle with Dwell

G83 = "G83" // Peck Drilling

G84 = "G84" // Right-Hand Tapping

G85 = "G85" // Boring, No Dwell, Feed Out

G86 = "G86" // Boring, Spindle Stop, Rapid Out

G98 = "G98" // Canned Cycle Return Level

G90 = "" // Absolute Distance Mode

G94 = "" // Units per Minute Mode

G20 = "" // Inch

G21 = "" // Millimeter

G61 = "" // Exact Path Mode

G64 = "" // Best Possible Speed

PAUSE = "P" // Best Possible Speed

RETRACT = "R" // Retract position

TOOL = "T" // tool number

SPINDLE = "S" // Spindle speed

M0 = "M00" // Program break

M6 = "M6" // tool change

M3 = "M3" // start spindle CW

M4 = "M4" // start spindle CCW

M5 = "M5" // stop spindle

M2 = "%" // program stop

M8 = "M8" // Mist coolant

M7 = "M7" // Flood coolantM9 = "M9" // Stop coolant

OC = "(" // open comment

CC = ")" // close comment

CRLF = "\r\n" // line return

SL = "%" // start line

EL = "%" // end line

You can go to a new line by inserting "{crlf}" in the command.

Example : SL = "%{crlf}%"
