202 Fixed Cycles: Contour Pocket, Contour Trains
7.9 CONTOUR TRAIN (Cycle 25, DIN/ISO: G125)
Cycle parameters
U Milling depth Q1 (incremental): Distance between
workpiece surface and contour floor. Input range -
99999.9999 to 99999.9999
U Finishing allowance for side Q3 (incremental):
Finishing allowance in the working plane. Input range
-99999.9999 to 99999.9999
U Workpiece surface coordinate Q5 (absolute):
Absolute coordinate of the workpiece surface
referenced to the workpiece datum. Input range:
-99999.9999 to 99999.9999
U Clearance height Q7 (absolute): Absolute height at
which the tool cannot collide with the workpiece.
Position for tool retraction at the end of the cycle.
Input range -99999.9999 to 99999.9999, alternatively
PREDEF
U Plunging depth Q10 (incremental): Infeed per cut.
Input range: -99999.9999 to 99999.9999
U Feed rate for plunging Q11: Traversing speed of the
tool in the spindle axis. Input range 0 to 99999.9999,
alternatively FAUTO, FU, FZ
U Feed rate for milling Q12: Traversing speed of the
tool in the working plane. Input range 0 to
99999.9999, alternatively FAUTO, FU, FZ
U Climb or up-cut? Up-cut = –1 Q15:
Climb milling: Input value = +1
Up-cut milling: Input value = –1
To enable climb milling and up-cut milling alternately
in several infeeds:Input value = 0
