 Milling depth Q1 (incremental value): Distance
between workpiece surface and contour floor.
 Finishing allowance for side Q3 (incremental
value): Finishing allowance in the working plane.
 Workpiece surface coordinate Q5 (absolute value):
Absolute coordinate of the workpiece surface
referenced to the workpiece datum.
 Clearance height Q7 (absolute value): Absolute
height at which the tool cannot collide with the
workpiece. Position for tool retraction at the end of
the cycle.
 Plunging depth Q10 (incremental value): Dimension
by which the tool plunges in each infeed.
 Feed rate for plunging Q11: Traversing speed of the
tool in the spindle axis.
 Feed rate for milling Q12: Traversing speed of the
tool in the working plane.
 Climb or up-cut ? (Up-cut = –1) Q15:
Climb milling: Input value = +1
Up-cut milling: Input value = –1
To enable climb milling and up-cut milling alternately
in several infeeds:Input value = 0
