R : Rem. cut depth (only with GV = 4; default: 1/100 mm)
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
Cycle run:
1 Calculate the proportioning of cuts
2 Start the first pass at the
Start point Z
3 Move to the End point thread Z2 at the programmed feed rate
4 Return on a paraxial path and approach for the next pass
5 Repeat 3 to 4 until the
Thread depth U is reached
6 Move to the Tool change point
according to the setting in
G14
