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

Corner radius

Q220: Radius of the pocket corner. If

you have entered 0 or a value smaller than the tool
radius, the TNC defines the corner radius to be equal
to the tool radius. In these cases, the TNC will not
display an error message. Input range 0 to
99999.9999

Finishing allowance for side

Q368 (incremental):

Finishing allowance in the working plane. Input range
0 to 99999.9999

Angle of rotation

Q224 (absolute): Angle by which

the entire pocket is rotated. The center of rotation is
the position at which the tool is located when the
cycle is called. Input range -360.0000 to 360.0000

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

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
