Explanation
Machining direction
40 = Center of contour (G40, approach and retract: straight line or vertical)
41 = Left of contour (G41, approach and retract: straight line or circle)
42 = Right of contour (G42, approach and retract: straight line or circle)
Contour approach movement
UNITS:
1 = Straight line
2 = Quarter-circle
3 = Semi-circle
4 = Vertical approach and retraction
TENS:
0 = Last movement, in the plane
1 = Last movement, spatial
Approach path or approach radius (inc; enter without sign)
Feedrate for intermediate paths (G94/G95 as to contour)
Contour approach movement (not vertical approach/retract)
UNITS:
1 = Straight line
2 = Quarter-circle
3 = Semi-circle
TENS:
0 = Last movement, in the plane
1 = Last movement, spatial
Retract path or retract radius (inc, to be entered without sign)
Reserved
Chamfer width (inc)
Insertion depth (tool tip) on chamfering (abs/inc), see _AMODE
Mode for evaluation of programmed geometrical data
UNITS: Reserved
TENS: Reserved
HUNDREDS: Select machining/only calculation of start point
0 = Compatibility mode
1 = Normal machining
