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 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. Input range
0 to 99999.9999

Pitch circle diameter

Q375: Enter the diameter of

the pitch circle. Input range 0 to 99999.9999

Reference for slot position (0/1/2/3)

Q367:

Position of the slot in reference to the position of the
tool when the cycle is called:
0: The tool position is not taken into account. The slot
position is determined from the entered pitch circle
center and the starting angle.
1: Tool position = Center of left slot circle. Starting
angle Q376 refers to this position. The entered pitch
circle center is not taken into account.
2: Tool position = Center of center line. Starting angle
Q376 refers to this position. The entered pitch circle
center is not taken into account.
3: Tool position = Center of right slot circle. Starting
angle Q376 refers to this position. The entered pitch
circle center is not taken into account.

Center in 1st axis

Q216 (absolute): Center of the

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