Re: [CAD_CAM_EDM_DRO] Question, can you assist?

That is a complex question, it really depends on your experience, I strongly
suggest working in 2d parts before jumping into 3d complex contours. Also
the IM Service does have a good product, Vector Cam, and yes I a member of
that group. There are a lot of factors when cutting aluminum or any type of
material.... type of bit, feed rates, depth of cut, weather to use climb
milling, ect, ect.
