cles
GH Type of offset
 0: Without offset
 1: From left
 2: From right
 3: Alternately left/right
A Approach (infeed) angle (range: –60° < A < 60°;
default 30°)
 A<0: Infeed on left thread flank
 A>0: Infeed on right thread flank
R Remaining cutting depth only with GV=4 (default 1/100
mm)
E Variable thread pitch (e.g. for manufacturing spiral
conveyors or extrusion shafts)
Q No. no load (number of dry runs)
IC Number of cuts—the infeed is calculated from IC and U.
Usable with:
 GV=0: Constant chip cross section
 GV=1: Constant infeed
