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
