Hoss, most newer cadcams can do high speed machining.
The biggest problem I remember was at 3.3m/min cutting feed the change in direction was brutal on the ballscrews, mazak drilled a hole thru the middle and ran chilled oil thru.
When it changes direction it needs a deceleration path, sort of like a loop in fresh air. (the cutter is tony hawk and the ramp is the workpeice, no dead stops) |
