As soon as machining on the rear face of a workpiece is finished,
machining on the front of the next workpiece starts. You can activate a
Work offset in the meantime for machining the front face using the
"Front face" function. You will typically use the work offset that was
active before the workpiece was gripped.
The main spindle is now the master spindle again.
5. Complete: Gripping, pulling (optinally with parting) and rear face steps
(see section 5.4.2).

"Machine". Here you can enter the paramerters for
the park position by hand also, if you fill out the pa-
ramerter fields "XP" and "ZP" (see section 5.4.3).
