Cycle parameters
Nominal diameter Q335: Nominal thread diameter.
Input range 0 to 99999.9999
Thread pitch Q239: Pitch of the thread. The
algebraic sign differentiates between right-hand and
left-hand threads:
+ = right-hand thread
= left-hand thread Input range -99.9999 to 99.9999
Thread depth Q201 (incremental): Distance
between workpiece surface and root of thread.
Input range -99999.9999 to 99999.9999
Total hole depth Q356 (incremental): Distance
between workpiece surface and bottom of hole.
Input range -99999.9999 to 99999.9999
Feed rate for pre-positioning Q253: Traversing
speed of the tool when moving in and out of the
workpiece, in mm/min. Input range 0 to 99999.9999
alternatively FMAX, FAUTO
Climb or up-cut Q351: Type of milling operation
with M3
+1 = climb
–1 = up-cut
Plunging depth Q202 (incremental): Infeed per cut.
The depth does not have to be a multiple of the
plunging depth. Input range 0 to 99999.9999
