Setup Clearance - HEIDENHAIN ITNC 530 - CYCLE PROGRAMMING User Manual

Cycle parameters
U Setup clearance Q200 (incremental): Distance
between tool tip and workpiece surface. Enter a
positive value. Input range 0 to 99999.9999,
alternatively PREDEF
U Depth Q201 (incremental): Distance between
workpiece surface and bottom of hole (tip of drill
taper). Input range –99999.9999 to 99999.9999
U Feed rate for plunging Q206: Traversing speed of
the tool during drilling in mm/min. Input range: 0 to
99999.999; alternatively FAUTO, FU.
U Plunging depth Q202 (incremental): Infeed per cut.
Input range 0 to 99999.9999. The depth does not
have to be a multiple of the plunging depth. The TNC
will go to depth in one movement if:
The plunging depth is equal to the depth
The plunging depth is greater than the depth
U
Dwell time at top Q210: Time in seconds that the
tool remains at setup clearance after having been
retracted from the hole for chip release. Input range 0
to 3600.0000, alternatively PREDEF
U Workpiece surface coordinate Q203 (absolute):
Coordinate of the workpiece surface. Input range:
-99999.9999 to 99999.9999
U
2nd setup clearance Q204 (incremental): Coordinate
in the spindle axis at which no collision between tool
and workpiece (fixtures) can occur. Input range 0 to
99999.9999, alternatively PREDEF
U Dwell time at depth Q211: Time in seconds that the
tool remains at the hole bottom. Input range 0 to
3600.0000, alternatively PREDEF
76
