Cycle parameters
Machining operation (0/1/2) Q215: Define
machining operation:
0 : Roughing and finishing
1 : Only roughing
2 : Only finishing
Side finishing and floor finishing are only machined
when the specific allowance (Q368, Q369) is
defined
Circle diameter Q223: Diameter of the finished
pocket. Input range 0 to 99999.9999
Finishing allowance for side Q368 (incremental):
Finishing allowance in the working plane. Input
range 0 to 99999.9999
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
–1 = up-cut
PREDEF: The TNC uses the value from the GLOBAL
DEF block (If you enter 0, climb milling is used for
machining)
Depth Q201 (incremental): Distance between
workpiece surface and bottom of pocket. Input
range -99999.9999 to 99999.9999
Plunging depth Q202 (incremental): Infeed per
cut. Enter a value greater than 0. Input range 0 to
99999.9999
Finishing allowance for floor Q369 (incremental
value): Finishing allowance in the tool axis. Input
range 0 to 99999.9999
Feed rate for plunging Q206: Traversing speed of
the tool while moving to depth in mm/min. Input
range 0 to 99999.999; alternatively
FAUTO, FU, FZ
