5.6 Contour milling
X0 Reference point in X direction (abs.)
X1 Depth with reference to X0 (inc.)
DYZ Maximum infeed in the YZ plane
Plane infeed in %: Ratio of plane infeed (mm) to milling cutter diameter (mm)
UYZ Finishing allowance in plane
Retraction If more than one insertion point is necessary, specify the retraction height to which
mode the tool retracts between insertion points:
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.
