I had a demo a few years back and it was pretty impressive. But Hypermill is expensive, especially when you add on all the 5-axis modules you may need. WorkNC, on the other hand, is equally impressive and substantially cheaper.
Used to use hypermill here....great package, I would put it up against any other. Like any other "advanced" software it has a big learning curve. Price was the biggest issue.....when Mastercam finally added in real 5 axis paths (in X2 I believe) we dropped hypermill. Way too much $$$ and it made more sense to only be using one package.
30 grand for mastercam's "lathe-mill"???? what a joke....as far as I am concerned, they don't have a real lathe-mill package.
15 grand got us mill level 3 with full 5 axis not long ago....but that was with a multiple seat discount (like 10 seats)
