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 finishing allowances (Q368, Q369) have been
defined.

Slot length

Q218 (value parallel to the reference axis

of the working plane): Enter the length of the slot

Slot width

Q219 (value parallel to the secondary 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

Finishing allowance for side

Q368 (incremental

value): Finishing allowance in the working plane.

Angle of rotation

Q224 (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.

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.

Climb or up-cut

Q351: Type of milling operation with

M3:
+1 = climb milling
–1 = up-cut milling
