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.

First side length
Q218 (incremental value): Pocket
length, parallel to the reference axis of the working
plane.

Second side length
Q219 (incremental value): Pocket
length, parallel to the minor axis of the working plane.

Pocket position
Q367: Position of the pocket in
reference to the position of the tool when the cycle is
called (see figure at center right):
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
