Retraction
mode
If more than one insertion point is necessary, specify the retraction height to which
the tool retracts between insertion points:
To retraction plane
Z0+safety clearance (for end face/end face C and end face Y only) or
X0+safety clearance (for peripheral surface/peripheral surface C and peripheral
surface Y only)
If there are no islands larger than Z0 (X0) in the pocket area, Z0 + safety clearance
(X0 + safety clearance) can be programmed as the retraction mode.
