Thread Chamfering (TC82)

[fooo]

Hello,

For the thread unit chamfering can be selected for the thread run-out and TC82 controls the length (TC82 * pitch) of the run-out.

I'm trying to get it work with MATRIX/INTEGREX, however I experience some problems:

Chamfering is programmed in the thread unit and TC82 is set to 4 (thread run-out should be 4 times the pitch), however the thread run-out appears to be much smaller than programmed; it never does a 4 * pitch movement at the thread end.

My first guess was that there might be some clearance issues, not allowing for such a "big" chamfer for the run-out, however playing with the TPC parameters concerning the clearance didn't work out.

Does somebody have an idea?

I've sent attachment from the parameter book (word doc) if you can open it.
otherwise formula is (pitch * (tc82 / 10)).
