Cycle parameters

Milling depth Q1 (incremental): Distance between
workpiece surface and contour floor. Input range
-99999.9999 to 99999.9999

Finishing allowance for side Q3 (incremental):
Finishing allowance in the working plane. Input
range -99999.9999 to 99999.9999

Workpiece surface coordinate Q5 (absolute):
Absolute coordinate of the workpiece surface. Input
range -99999.9999 to 99999.9999

Clearance height Q7 (absolute): Absolute height at
which the tool cannot collide with the workpiece (for
intermediate positioning and retraction at the end of
the cycle). Input range -99999.9999 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

CLIMB OR UP-CUT Q15:
Climb milling: Input value = +1
Conventional up-cut milling: Input value = –1
Climb milling and up-cut milling alternately in several
infeeds: Input value = 0
