I work as a mould machine manufacturer, and I got a copy of mastercam from the factory so that I learn how to use it. I had a drawing in inventor that was ready and just imported it into mastercam x6. Now I would like to machine the outer part first than the inner and finish it after. What roughing contour would be ideal for this type of work? I tried the normal contour, but the don't know how to make the radius too. And are there any options to do the plunging outside the material area? Thanks before hand.
