Explanation
Maximum plane infeed, for unit, see _AMODE
Length of premachining (inc)
Width of premachining (inc)
Depth of premachining (inc)
Radius of helical path on helical insertion
Maximum insertion angle for oscillation
Helical pitch on helical insertion
Reserved
Chamfer width (inc)
Insertion depth (tool tip) on chamfering (abs/inc), see _AMODE
Geometrical mode
UNITS: Reserved
TENS: Reserved
HUNDREDS: Select machining/only calculation of start point
0 = Compatibility mode
1 = Normal machining
THOUSANDS: Dimensioning via center/corner
0 = Compatibility mode
1 = Dimensioning via center
2 = Dimensioning of corner point, pocket position +LENG/+WID
3 = Dimensioning of corner point, pocket position -LENG/+WID
4 = Dimensioning of corner point, pocket position +LENG/-WID
5 = Dimensioning of corner point, pocket position -LENG/-WID
TEN THOUSANDS: Complete machining/remachining
0 = Compatibility mode (process _AP1, _AP2 and _AD as before)
1 = Complete machining
2 = Remachining
Display mode
UNITS: Machining plane G17/G18/G19
0 = Compatibility, the level effective before cycle call remains active
1 = G17 (only active in the cycle)
2 = G18 (only active in the cycle)
3 = G19 (only active in the cycle)
TENS: Type of feedrate: G group (G94/G95) for surface and depth feedrate
0 = Compatibility mode
1 = G code as before cycle call. G94/G95 same for surface and depth feedrate
