what is the factor that:
"most" significantly affects High Speed Machining on a Fadal
HSM is most commonly defined as feed rates above what the Fadal is capable of delivering.
Feeds lower than 300 IPM would be not be considered HSM by some industry definitions. HSM is somewhat relative, because we all refer to processes that are faster than what has been possible to date on our own machinery. But I think that using the phase HSM when we are using feed rates in this lower range of the spectrum <300 IMP, deminishes the term HSM.
The term High Velocity Machining should definetly be reserved for describing processes higher than 1000 IPM. At this level there is much less discussion going on.
There are CNCs out there accurately feeding at "programmed" feeds from 1000 to 3000 IPM. Not on a Fadal...
I say "programmed feeds" because a good control with intelligent look ahead and feed optimization can be programmed at an optimum feed rate for the tool in use, and the control slows down relative to the angular change in dirrection. Like the Fadal does in point to point, only with a much higher degree of accuracy.
Using a .187 dia. Carbide End Mill. How fast can your Fadal mill a slot .250" x 1.000" and hold +/-.001 in 6061-T6 Aluminum say .2 dp?
Feed = ?
