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.
Q463 Maximum cutting depth?: Maximum infeed
(radius value) in radial direction. The infeed is
divided evenly to avoid abrasive cuts. Input range
0.001 to 999.999
Q507 Direction (0=bidir./1=unidir.)?: Cutting
direction:
0: Bidirectional (in both directions)
1: Unidirectional (in contour direction)
Q508 Offset width?: Reduction of cutting length.
After clearance roughing, the remaining material
is removed with a single cut. If required, the TNC
limits the programmed offset width.
Q509 Depth compensat. for finishing?:
Depending on factors such as workpiece material
or feed rate, the tool tip is displaced during a
turning operation. You can correct the resulting
infeed error with the turning depth compensation
factor.
Q488 Feed rate for plunging (0=auto)?: Feed rate
for machining plunging elements. This input value
is optional. If it is not programmed, then the feed
rate defined for turning operations applies.
