Exercise 2 ­ Using depth cuts, island facing, and tapered walls Depth cuts, island facing, and tapered walls are often used together on more complex pocket toolpaths. For example, tapered walls require multiple depth cuts so that the offset for the walls can be computed at each depth. Also, when you face the islands, Mastercam can automatically use the island depth as one of the depth cut values. [. . . ] To act as a boundary for a entity or surface.
