The Roughing process creates offset, zig zag, and face milling routines designed to remove material quickly. Cut shape selection for roughing is very similar to contouring. • Selecting a closed 2D contour for the cut shape will create a roughing routine to remove material from the inside of the selected …

Contouring operations are designed to take a single finishing pass along a selected cut shape. The cut shape for a contouring operation can be a solid, a sheet, selected faces of a solid or sheet, a contour (connected 2D shape) or some combination of the above. • Selecting only a …

The stock shape is used to create machining operations and display the cut part rendered image of the part once those operations have been generated. Stock that defines a part may be set in one of three ways. These methods are the workspace stock in the Document Control dialog, a …

The Machining palette contains function tiles which are used to create machining processes, including: drilling, contouring, roughing, surfacing, and threading. Combining a function tile with a tool tile in the process list displays a machining process dialog specific to the function where all of the machining parameters are entered. This …

The Surface Tolerance affects how closely the toolpath approximates the surface to be machined. The tolerance value specifies an amount that the toolpath can deviate from the actual surface, either on the inside or the outside. The example illustrates a valid toolpath and displays the surface being machined and the …

GibbsCAM uses the Gen 3 solids toolpath engine. The Gen 3 engine provides many improvements over Gen 2, including smoother and more optimized toolpath for contouring operations. Gen 3 is optimized to produce toolpath consisting of lines and arcs. Compatibility With Earlier Versions If you open a part that was …

This section contains reference information on the multi-surface machining functions in the system. The first part describes some of the terms and concepts for using the multi-surface machining capabilities. For information on the standard machining functions provided in the Production Milling module, see Mill.

Avoid congruent face modeling The system attempts to solve co-planar congruency problems (where the faces that are congruent are planes) and is often successful. However, as a general rule you should avoid Boolean operations with congruent faces. When possible, adjust one of the bodies (by offsetting faces, etc.) so as …

You use the History, Recreate, and Rebuild functions to make the necessary changes. The History lists maintain all of the bodies that are used to create any model. Anytime a solid is created or modified, it is assigned a name and reference. If a modification is made to an existing …

In this example, you create the new extrusion with the larger diameter and then replace the old smaller extrusion with the new larger extrusion by using Replace. Replace substitutes a solid with any other solid in any stage of the tree. Then, you use the Rebuild function to incorporate the …
