Explanation
Retraction plane (abs)
Reference point of tool axis (abs)
Safety clearance (to be added to reference point, enter without sign)
Multiple-edge depth (abs/inc), see _AMODE
Number of edges (1...n)
Width across flats or edge length (depending on _VARI)
("SW" for width across flats, "L" for edge length)
Width across flats only if even number of edges, and single edge
Spigot reference point, 1st axis (abs)
Spigot reference point, 2nd axis (abs)
Angle of rotation, center of edge against 1st axis (X axis)
Corner rounding with _NUM > 2 (radius/chamfer, see _AMODE) (inc, to be entered without
sign)
("R1" for radius, "FS1" for chamfer)
Unmachined diameter of spigot
Maximum infeed width (for unit, see _AMODE)
Maximum depth infeed
Finishing allowance, plane
Finishing allowance, depth
Machining feedrate
Milling direction
0 = Down-cut
1 = Up-cut
