The ease of being able to visually see what the different planes of machining are is a great assistance for knowing what the machine will do.
I don't like that I am unable to select and manipulate individual chains in the machining operations. I can change start points in the chains, but I'm not able to tell the software what order I want the machine to cut the parts in.
Like my review heading states, we come to use HSM with a background in Mastercam. Mastercam is the industry standard, and for good reason. The ease of use, flexibility and years of experience cannot be dismissed as old school or unintelligent. So coming from that background, HSM has a lot of ground to cover. I think it's headed in the right direction.
It makes it easy to allow for easy product changes so that there is a consistent flow from design to prototype to manufacturing.
