CHAINING
INSTRUCTOR GUIDE
About
chaining
Definition: Chaining is a process used to select a number of entities, (lines, arcs,
points, splines etc.) Chaining is used when modifying or transforming existingentities or when creating a toolpath The entities form a chain when the distancebetween two consecutive entities is less than the chaining tolerance (.0001 in thesystem configuration)
When Chaining Geometry to create a toolpath it is important in certain
circumstances to chain the geometry in the proper direction, as it will determinethe direction the cutter travels when machining the part Below is an example ofhow to select geometry using chaining method
Note: To change the direction of the arrows just click on Reverse from the Chaining dialog box.

Analyze Chain
Click the first entity of the chain, and then click the last entity of the chain
Branch point is the position where the endpoints of two or more entities meet.
Branch points indicate where there are different paths that the chain can take.
When Mastercam encounters a branch point during chaining, it prompts you tochoose the path for the chain to follow
