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
 1st side length Q218 (incremental): Pocket length,
parallel to the reference axis of the working plane.
Input range 0 to 99999.9999
 2nd side length Q219 (incremental): Pocket length,
parallel to the minor axis of the working plane. Input
range 0 to 99999.9999
 Depth Q201 (incremental): Distance between
workpiece surface and bottom of pocket. Input range
-99999.9999 to 99999.9999
 Pocket position Q367: Position of the pocket in
reference to the position of the tool when the cycle is
called:
0: Tool position = Center of pocket
1: Tool position = Lower left corner
2: Tool position = Lower right corner
3: Tool position = Upper right corner
4: Tool position = Upper left corner
 Plunging depth Q202 (incremental): Infeed per cut.
Enter a value greater than 0. Input range 0 to
99999.9999
 Feed rate for milling Q207: Traversing speed of the
tool during milling in mm/min. Input range 0 to
99999.999; alternatively FAUTO, FU, FZ

the tool while moving to depth in mm/min. Input
range 0 to 99999.999; alternatively FAUTO, FU, FZ
 Feed rate for finishing Q385: Traversing speed of
the tool during side and floor finishing in mm/min.
Input range 0 to 99999.9999; alternatively FAUTO, FU,
FZ
 Finishing allowance for side Q368 (incremental):
Finishing allowance in the working plane. Input range
0 to 99999.9999
 Finishing allowance for floor Q369 (incremental
value): Finishing allowance in the tool axis. Input
