Explanation
Machining type
UNITS: Reserved
TENS: Machining process
1 = Roughing
2 = Finishing
3 = Roughing and finishing
HUNDREDS: Position longitudinal/transverse external/internal +Z/+Z and +X/-X
1 = Longitudinal/external +Z
2 = Transverse/internal -X
3 = Longitudinal/internal +Z
4 = Transverse/internal +X
5 = Longitudinal/external -Z
6 = Transverse/external -X
7 = Longitudinal/internal -Z
8 = Transverse/external +X
THOUSANDS: Position of reference point
0 = Upper reference point
1 = Lower reference point
TEN THOUSANDS: Define effect of finishing allowances
0 = Finishing allowance U parallel to contour
1 = Separate UX and UZ finishing allowances
D number for 2nd edge of tool
> 0 = D number for correction of 2nd edge of grooving tool
0 = No 2nd edge programmed
Number of grooves (0 = 1 groove)
Distance between grooves (only needed when _NUM > 1)
Feedrate
Identification for form of groove corresponds to vertical softkey for form selection
0 = 90° sides without chamfers/rounding
1 = Inclined sides with chamfers/rounding (without α0)
2 = as 1, but on taper (with α0)
Finishing allowance in X axis, see _VARI (TEN THOUSANDS) (to be entered without sign)
Finishing allowance in z axis, see _VARI (TEN THOUSANDS) (to be entered without sign)
Display mode
UNITS: Machining plane G17/G18/G19
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)
Programming cycles externally
18.1 Technology cycles
