Type of starting element Q501: Define the type of
element at the start of the contour (circumferential
surface):
0
: No additional element
1
: Element is a chamfer
2
: Element is a radius
Size of starting element Q502: Size of the starting
element (chamfer section)
Radius of contour edge Q500: Radius of the inside
contour edge. If no radius is specified, the radius of
the cutting insert is generated.
Type of end element Q503: Define the type of
element at the end of the contour (face):
0
: No additional element
1
: Element is a chamfer
2
: Element is a radius
Size of end element Q504: Size of the end element
(chamfer section)
Maximum cutting depth Q463: Maximum infeed in
axial direction. The infeed is divided evenly to avoid
abrasive cuts.
Roughing feed rate Q478: Feed rate during
roughing. If M136 has been programmed, the
value is interpreted by the TNC in millimeters per
revolution, without M136 in millimeters per minute.
Oversize in diameter Q483 (incremental): Diameter
oversize for the defined contour
Oversize in Z Q484 (incremental): Oversize for the
defined contour in axial direction
Finishing feed rate Q505: Feed rate during
finishing. If M136 has been programmed, the
value is interpreted by the TNC in millimeters per
revolution, without M136 in millimeters per minute.
Contour smoothing Q506:
0
: After each cut along the contour (within the
infeed range)
1
: Contour smoothing after the last cut (complete
contour); retract below 45°
2
: No contour smoothing; retract below 45°
