Cycle parameters
Milling depth Q1 (incremental): Distance between
the cylindrical surface and the floor of the contour.
Input range -99999.9999 to 99999.9999
Finishing allowance for side Q3 (incremental):
Finishing allowance in the plane of the unrolled
cylindrical surface. This allowance is effective in the
direction of the radius compensation. Input range
-99999.9999 to 99999.9999
Set-up clearance Q6 (incremental): Distance
between the tool tip and the cylinder surface. Input
range 0 to 99999.9999
Plunging depth Q10 (incremental): Infeed per cut.
Input range -99999.9999 to 99999.9999
Feed rate for plunging Q11: Traversing speed
of the tool in the spindle axis. Input range 0 to
99999.9999, alternatively
FAUTO, FU, FZ
Feed rate for milling Q12: Traversing speed of
the tool in the working plane. Input range 0 to
99999.9999, alternatively
FAUTO, FU, FZ
Cylinder radius Q16: Radius of the cylinder on
which the contour is to be machined. Input range 0
to 99999.9999
Dimension type? deg=0 MM/INCH=1 Q17: The
coordinates for the rotary axis of the subprogram
are given either in degrees (0) or in mm/inches (1).
