Fixed Cycles: Cylindrical Surface | CYLINDER SURFACE (Cycle 27, DIN/ISO: G127, software option 1)

Cycle parameters

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