Hi all,
I have a problem with rigid tapping on a lathe with life tooling and a fanuc Oi-TF controller.
The machine this occurs on is not very much used even though it is already a year old and supplier customer support is nearly zero.
When the tap reaches the botom of the hole it dwels there for about a second with the spindle still running before reversing the spindle and retracting in Z. See the attached video at the bottom
program used is
G97 S300 M53
G0 X465 Z10
M29 S300 M53
G84 C0 Z-23 R-5 H[360/6] K6 F[300*1.25]
G80
have been playing around all day without any succes.
Tapping without rigid tapping by the way gives the same result : dwelling at bottom of hole with spindle running.
