Hi Rich:
Report from John Stevenson on the test he did today..
>>>Ran a 1.5mm pitch thread for 50 mm, after 3 passes it was way off so
bailed out.
Did what Rich said and switch averaging off and re ran the thread.
All passes looked to be dead nuts on, bit of double thread at the end
from the first 3 passes spoilt it a bit, quick clean up with
scotchbrite and checked against a 1.5mm tap and it's the best thread I
have done to present. Very slight pitch error over the 50mm, probably
1/4 pitch out at the end.
This is the most promising long thread that I have done to present,
aim to tune in to read 600 better but not certain how critical this
is.
>>>
As you can see he had to switch off averagiung, where you need it on. Ntot sure what that means yet, but it seems both of you are getting better threads than
ever before.
Im thinking if averaging kills the thread, then the RPM must be wavering more than normal OR that the new code has changed it so that averaging doesnt help,
and non-averaging may be better.. Not sure yet..
Anyway, couple days for new code I think..
Thx
