If you are doing all the machining for the pocket at once, i.e.
centering, rough-drilling and removing stock directly in sequence, and
do not set the additional parameters for centering/rough-drilling,
ShopMill will take these parameter values from the stock removal
(roughing) machining step.

Retraction mode before new infeed
If a machining operation requires several insertion points, you can program the
retraction height:
• To retraction plane
• Z0 + safety clearance
On making the transition to the next insertion point, the tool returns to this height. If
there are no elements larger than Z0 in the pocket area, "Z0 + safety clearance" can
be selected as the retraction mode.
