PL Machining plane for milling:
G17 (XY)
G18 (ZX)
G19 (YZ)
Note: The plane settings can already be defined. Ask the machine manufacturer in
order that the selection box is available.
Machining plane when turning:
G18 (ZX)
SC The safety clearance defines how close the tool can approach the workpiece in rapid
traverse.
Note
Enter the safety clearance without sign into the incremental dimension.
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.
