Cycle parameters
8
Milling depth Q1 (incremental): Distance between
the cylindrical surface and the floor of the contour.
Input range -99999.9999 to 99999.9999
8
Finishing allowance for side Q3 (incremental):
Finishing allowance on the ridge wall. The finishing
allowance increases the ridge width by twice the
entered value. Input range -99999.9999 to
99999.9999
8
Set-up clearance Q6 (incremental): Distance
between the tool tip and the cylinder surface. Input
range 0 to 99999.9999
8
Plunging depth Q10 (incremental): Infeed per cut.
Input range -99999.9999 to 99999.9999
8
Feed rate for plunging Q11: Traversing speed of the
tool in the spindle axis. Input range 0 to 99999.9999,
alternatively FAUTO, FU, FZ
8
Feed rate for milling Q12: Traversing speed of the
tool in the working plane. Input range 0 to
99999.9999, alternatively FAUTO, FU, FZ
8
Cylinder radius Q16: Radius of the cylinder on which
the contour is to be machined. Input range 0 to
99999.9999
8
Dimension type? ang./lin. Q17: The coordinates for
the rotary axis of the subprogram are given either in
degrees (0) or in mm/inches (1).
8
Ridge width Q20: Width of the ridge to be machined.
Input range -99999.9999 to 99999.9999
