Machining operation Q215: Define machining
operation:
0 : Roughing and finishing
1 : Only roughing
2 : Only finishing to finished dimension
3 : Only finishing to oversize
Set-up clearance Q460 (incremental): Distance for
retraction and pre-positioning
Reverse contour Q499: Define the machining
direction of the contour:
0 : Contour machined in the programmed direction
1 : Contour machined in reverse direction to the
programmed direction
Maximum cutting depth Q463: Maximum infeed
(radius value) in radial direction. The infeed is divided
evenly to avoid abrasive cuts.
Roughing feed rate Q478: Feed rate during
roughing. If M136 has been programmed, the
