Milling rigid foam

Thanks to Jonathan White :

Think of the sheets of pink/green insulation foam you can buy at the blue or orange hardware store, I did a small project on the EBF yesterday.  After angsting about it for awhile, I gave it a shot and 10,000RPM, 150IPM, cutting the full 3/4 deep cut in one pass with an upcut 1/4 endmill, conventional milling, worked perfectly - crisp edges, no burning.  The stepover was only 40% which could have been increased to reduce cut time.  The only issue was that the bristles on the EBF dust hood scratched the top surface a bit, but this was a functional project so no big deal.  That could be avoided by raising the dust hood a little bit.

I did mine with a 3D printed clamp system I’ve created.
