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).

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‐

When machining with optimized retraction, the tool travels across the workpiece

at the machining feedrate depending on the contour and with a safety clearance

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.
