Regroove (longitudinal) thread
With this cycle, you can repair a single-start thread. Since you have
already unclamped the workpiece, MANUALplus needs to know the
exact position of the thread.
Cycle run
1 Pre-position threading tool so that tip is at center of thread groove.
2 Transfer the tool position and the spindle angle with “Take over
position”.
3 Manually move the tool out of the thread groove.
4 Position tool to “start point X, Z”.
5 Start cycle with “Input finished”, then press the “Cycle START”
button.
Information on the cycle parameters:
C:
Measured angle (spindle angle)
ZC: Measured position (tool position)
F1: Thread pitch (is evaluated for the feed rate)
U Thread depth – default:
• external threads: U=0.6134*F1
• internal threads: U=–0.5413*F1
I: 1st cutting depth
• I<U: I is the depth of the first cut
• No input: the thread is regrooved in one pass
• A thread is always regrooved at an infeed angle of 0°.
• “Cycle STOP“ only becomes effective at
the end of a thread cut.
• The feed rate and spindle speed overrides
are disabled during execution of the cycle.
