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; alternatively PREDEF
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 or in mm (or inches).
