Cycle parameters

Machining operation (0/1/2)

Q215: Define the

machining operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing
Side finishing and floor finishing are only executed if
the respective finishing allowance (Q368, Q369) has
been defined

Slot length

Q218 (value parallel to the reference axis

of the working plane): Enter the length of the slot.
Input range 0 to 99999.9999

Slot width

Q219 (value parallel to the minor axis of

the working plane): Enter the slot width. If you enter
a slot width that equals the tool diameter, the TNC
will carry out the roughing process only (slot milling).
Maximum slot width for roughing: Twice the tool
diameter. Input range 0 to 99999.9999

Finishing allowance for side

Q368 (incremental):

Finishing allowance in the working plane.

Angle of rotation

Q374 (absolute): Angle by which

the entire slot is rotated. The center of rotation is the
position at which the tool is located when the cycle is
called. Input range -360.000 to 360.000

Slot position (0/1/2/3/4)

Q367: Position of the slot

in reference to the position of the tool when the cycle
is called:
0: Tool position = Center of slot
1: Tool position = Left end of slot
2: Tool position = Center of left slot circle
3: Tool position = Center of right slot circle
4: Tool position = Right end of slot

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
