Q503 End element type (0/1/2)?: Define the
type of element at the end of the contour (plane
surface):
0: No additional element
1: Element is a chamfer
2: Element is a radius
Q504 Size of end element?: Size of the end
element (chamfer section)
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
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.
Q506 Contour smoothing (0/1/2)?:
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°
