Cycle parameters

Q215 Machining operation (0/1/2/3)?: Define
machining operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing to finished dimension
3: Only finishing to oversize
Q460 Set-up clearance?: Reserved, currently
without function
Q478 Roughing feed rate?: Feed rate for
roughing. If M136 has been programmed, the
value is interpreted by the TNC in millimeters
per revolution, without M136 in millimeters per
minute.
Q483 Oversize for diameter? (incremental):
Diameter oversize for the defined contour
Q484 Oversize in Z? (incremental): Oversize for
the defined contour in axial direction
Q505 Finishing feed rate?: Feed rate for
finishing. If M136 has been programmed, the
value is interpreted by the TNC in millimeters
per revolution, without M136 in millimeters per
minute.
Q479 Machining limits (0/1)? : Activate cutting
limit:
0: No cutting limit active
1: Cutting limit (Q480/Q482)
Q480 Value of diameter limit?: X value for
contour limitation (diameter value)
Q482 Value of cutting limit in Z?: Z value for
contour limitation
Q463 Limit to plunging depth?: Max. recess
depth per cut
448
