order that the selection box is available.
Retraction plane RP
Safety clearance SC:
Planes above the workpiece.
During machining, the tool travels in rapid traverse from the tool change point to the
return plane (RP) and then to the safety clearance (SC). The machining feedrate is
activated at this height. When the machining operation is finished, the tool traverses
at the machining feedrate away from the workpiece to the safety clearance height. It
traverses from the safety clearance to the retraction plane and then to the tool change
point in rapid traverse. The retraction plane is entered as an absolute value.
The safety clearance must be entered as an incremental value (without sign).
Machining direction
When machining a pocket, a longitudinal slot or a spigot, ShopMill takes the machining
direction (down-cut or up-cut) and the spindle direction in the tool list into account.
The pocket is then machined in a clockwise or counterclockwise direction.
During path milling, the programmed contour direction determines the machining di‐
rection.

● Optimized
When machining with optimized retraction, the tool travels across the workpiece
at the machining feedrate depending on the contour and with a safety clearance
(SC).
● To RP
When retracting to RP, the tool is retracted to the retraction plane when the
machining step is complete and infeeds at the new position. Collisions with
workpiece obstacles are thus prevented when the tool is retracted and fed in, e.g.
when holes in pockets or grooves are machined at different levels and positions.
