There are a million CAM programs out there. The one that I use is GibbsCAM it is a very versatile program endorsed by Jay Leno. So it's got to be good. Any way, this is my intro tutorial which merges an AutoDesk Inventor file with GibbsCAM and then is exported to Mach 3. It is a very unique assignment, but if you have all three software programs and you need a place to start this is it.
