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
