5
GH: Type of offset
0: Without offset
1: From left
2: From right
3: Alternating left/right
A: Approach ang. (range: –60° < A < 60°; default: 30°)
A < 0: Infeed on left thread flank
A > 0: Infeed on right thread flank
R: Rem. cut depth (only with GV = 4; default: 1/100 mm)
E: Incremental gradient – Variable thread pitch (e.g. for
manufacturing spiral conveyors or extrusion shafts)
Q: Number no-load.
IC: Number of cuts – the infeed is calculated from IC and U
Usable with:
GV = 0: Constant chip cross section
GV = 1: Constant infeed
MT: M after T: M function that is executed after the tool call T
MFS: M at beginning: M function that is executed at the
beginning of the machining step
MFE: M at end: M function that is executed at the end of the
machining step
WP: No. of spindle – Displays which workpiece spindle is used
to execute the cycle (machine-dependent)
Main drive
Opposing spindle for rear-face machining
BW: Angle in the B axis (machine-dependent)
CW: Reverse the tool (machine-dependent)
HC: Shoe brake (machine-dependent)
DF: Miscellaneous function (machine-dependent)
Type of machining for technology database access:
Thread cutting
Parameter combinations for Taper angle:
X1/Z1, X2/Z2
X1/Z1, Z2, W
