Hi Everyone.
I hope someone can help me here.
We have a Mori MV 40 with a Fanuc 10m (year approx 1987) and rigid tapping is enabled.
G84.2 calls up the rigid tapping but what happens is that the tap goes to the bottom of the hole ok then changes direction fine comes about half way out of the hole and then the spindle does something weird, it all happens pretty fast but it looks like it speeds up and then down again, the feed stays the same through the whole process.
As you can imagine it just pulls half of the threads on the way out.
I have had our local Fanuc Guru looking at it and he thought it was a parameter wrongly set, he was going to get a copy from another machine the same but he never came back.
I would be very thankful for any help anyone could offer here.
