gibbscam. super easy. it has some limits...but its a nice package mill and lathe both. i had problems with their customer service though... but it is easy to use..very user friendly interface..
*i herd the new bobcad isnt to bad....(MILLING)
*i prefer unigraphics (NX) thats what i use
...just look up some names and see what they might have to offer. have them show you a demo. check prices. and see what software might fit your demands
