Cycle parameters
U
Setup clearance Q200 (incremental): Distance
between tool tip (at starting position) and workpiece
surface. Standard value: approx. 4 times the thread
pitch. Input range 0 to 99999.9999, alternatively
PREDEF
U
Total hole depth Q201 (thread length, incremental):
Distance between workpiece surface and end of
thread. Input range -99999.9999 to 99999.9999
U
Feed rate F Q206: Traversing speed of the tool during
tapping. Input range: 0 to 99999.999, alternatively
FAUTO
U
Dwell time at bottom Q211: Enter a value between 0
and 0.5 seconds to avoid wedging of the tool during
retraction. 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
The feed rate is calculated as follows: F = S x p
F: Feed rate (mm/min)
S: Spindle speed (rpm)
p: Thread pitch (mm)
Retracting after a program interruption
If you interrupt program run during tapping with the machine stop
button, the TNC will display a soft key with which you can retract the
tool.
