It's has been a while since I have been on here, not a lot new to figure out, until this project. I am making some parts out of foamed glass, sometimes called fart rock in the industry. Have any of you ever machined it? It is super delicate, cuts with a saw, and can be drilled. If you have ever worked with it on a CNC, I'd appreciate your tips. I have been very careful with my toolpaths. Making sure to keep thin cross section areas well supported up to the final cuts. This one could be an adventure.
