T/F You use cutter compensation exclusively for milling operations and only when you are side milling.
True
T/F Simplifying calculations is a cutter compensation benefit for manual programmers.
True
List the three steps to program cutter radius compensation.
- instate cutter compensation
- program the tool path to be machined
- cancel cutter compensation
Describe the three motion commands needed to instate cutter compensation.
- an X/Y axis motion to the prior position
- one or more Z axis motions to the Z axis work surface
- the instating command that brings the milling cutter, in X and/or Y, to the first surface to mill
