Explanation
Diameter/radius of premachining (inc)
Depth of premachining (inc)
Radius of helical path on helical insertion
Helical pitch on insertion on helical path
Reserved
Chamfer width (inc)
Insertion depth (tool tip) on chamfering (abs/inc), see _AMODE
Geometrical mode
UNITS: Reserved
TENS: Reserved
HUNDREDS: Machining/calculation of start point
0 = Compatibility mode
1 = Normal machining
THOUSANDS: Reserved
TEN THOUSANDS: Complete machining/remachining
0 = Compatibility mode (process _AP1 and _AD as before)
1 = Complete machining
2 = Remachining
Display mode
UNITS: Machining plane G17/18/19
0 = Compatibility, the plane 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
HUNDREDS:
0 = Compatibility mode (enter _CDIAM/_AP1 as radius)
1 = Enter _CDIAM/_AP1 as diameter
Alternative mode
UNITS: Pocket depth (Z1)
0 = Absolute (compatibility mode)
1 = Incremental
TENS: Unit for infeed width (DXY)
0 = mm
1 = % of tool diameter
HUNDREDS: Insertion depth for chamfering (ZFS)
0 = Absolute
1 = Incremental
