I am thinking of getting the HSM look ahead option on a new VF-3, and am wondering how good it actually works. I will be mostly doing molds on the mill using a cam software. I do not want to do any finish polishing after machining.
Is the suface finish much better on 3-d surfaces?
Does it make a big difference in machining time?
If any one has any direct experience with it I would love to hear about it. Its only about $2000 extra, and I have already convinced my boss that it would probably be worth it for the type of work I will be doing.
