Cycle parameters
U
Nominal diameter
Q335: Nominal thread diameter.
Input range 0 to 99999.9999
U

Q201 (incremental): Distance between
workpiece surface and root of thread. Input range -
99999.9999 to 99999.9999
U
Countersinking depth
Q356 (incremental): Distance
between tool point and the top surface of the
workpiece. Input range -99999.9999 to 99999.9999
U
Feed rate for pre-positioning
Q253: Traversing
speed of the tool in mm/min when plunging into the
workpiece, or when retracting from the workpiece.
Input range 0 to 99999.999 alternatively FMAX, FAUTO,
PREDEF
.
U
Climb or up-cut
Q351: Type of milling operation with
M3
+1 = climb milling
–1 = up-cut milling
Alternatively PREDEF
U
Setup clearance
Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999, alternatively PREDEF
