Center in 2nd axis

Q217 (absolute): Center of the

pitch circle in the minor axis of the working plane.
Only effective if Q367 = 0. Input range -99999.9999
to 99999.9999

Starting angle

Q376 (absolute): Enter the polar angle

of the starting point. Input range -360.000 to 360.000

Angular length

Q248 (incremental): Enter the angular

length of the slot. Input range 0 to 360.000

Stepping angle

Q378 (incremental): Angle by which

the entire slot is rotated. The center of rotation is at
the center of the pitch circle. Input range -360.000 to

Number of repetitions

Q377: Number of machining

operations on a pitch circle. Input range 1 to 99999

Feed rate for milling

Q207: Traversing speed of the

tool in mm/min while milling. Input range 0 to
99999.999; alternatively FAUTO, FU, FZ

Climb or up-cut

Q351: Type of milling operation with

M3:
+1 = climb milling
–1 = up-cut milling
+0 = climb milling; if a mirror function is active, the
climb milling method remains effective
Alternatively PREDEF

the tool in mm/min while moving to depth. Input
range 0 to 99999.999; alternatively FAUTO, FU, FZ

Infeed for finishing

Q338 (incremental): Infeed per

cut. Q338=0: Finishing in one infeed. Input range 0 to
99999.9999
