Great CAM for Rhino
I'm a musical instrument maker, and have recently started using Rhino to design instruments. I've been using Vectric VCarve Pro for 2 and 2.5d work, and it works very well. But I needed a 3D CAM solution that would keep my X and Y origins at the same place as my Rhino models (this lets me use some of the same indexing jigs that I use with VCarve without a lot of fiddling around). I also needed a CAM solution that would allow engraving along a curve.
To make a long story short, I downloaded trial versions of several CAM solutions within my price range, and MadCAM came out on top easily. I've been using it now for several weeks, and I've found it very intuitive to use, and the toolpaths it has generated work very well on my CNC machine. The few questions I've had have been quickly answered by the MadCAM folks. Rhino and MadCAM make a very powerful combination for musical instrument makers.
