To low Feed
Fswizard, great software.... But.
I have a rule of thumb, newer go lower than fn 0.05mm feed for a fhm end mill.
When I calc matr. a36 44w (St 52-3)
Fhm ø16mm cutter tiAIN z=4
Doc 18mm woc 12mm
Result is speed 175 m/min that's pretty good.
.But then it's say fz 0.037mm
That's mutch to low p.t. We are running with 0.09mm.
The supplyer calc. Toolscout say 0.075mm
What is going on?
Thank you Morten Lerager
