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.
Q499 Reverse contour (0=no/1=yes)?: Machining
direction:
0: Machining in contour direction
1: Machining opposite the contour direction
