Re: [CAD_CAM_EDM_DRO] Re: Machining smooth Curves

Rab:

I just took a look at your site. Awesome!!!, I think the stuff your
turning out is great. As Master5 is a preprocessing controller, It would be
possible to input bezier's or nurbs points in a toolpath without sacrificing
speed. If there were a G-Code standard for it, it would be interesting to
try it out. Does anyone know of a standard way to import Bezier Curves into
a controller program?

Keep up the good ARTwork.
