This is interesting. I wrote Tagxedo http://www.tagxedo.com which is another kind of constrained packing problem and there is a bit of similarity in the approaches. This is the first time I've heard of CNC packing and part nesting... May I ask what kind of software and how much they are selling for?

The one I compared with is mynesting which has a pay-per-use model. They also make nestfab, which is 2k+ per seat I believe.

There are lots of others at various price point, but none that are free it seems.
