HEIDENHAIN ITNC 530 - CYCLE PROGRAMMING

HEIDENHAIN iTNC 530 229
8.4 CYLINDER SURFACE Ridge Milling (Cycle 29, DIN/ISO: G129, Software
Option 1)
Cycle parameters
U Milling depth Q1 (incremental): Distance between
the cylindrical surface and the floor of the contour.
Input range: -99999.9999 to 99999.9999
U Finishing allowance for side Q3 (incremental):
Finishing allowance on the ridge wall. The finishing
allowance increases the ridge width by twice the
entered value. Input range: -99999.9999 to
99999.9999
U Setup clearance Q6 (incremental): Distance between
the tool tip and the cylinder surface. Input range 0 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 Cylinder radius Q16: Radius of the cylinder on which
the contour is to be machined. Input range 0 to
99999.9999
U Dimension type? ang./lin. Q17: The dimensions for
the rotary axis of the subprogram are given either in
degrees (0) or in mm/inches (1).
U Ridge width Q20: Width of the ridge to be machined.
Input range -99999.9999 to 99999.9999
