They need this high-tech foam a certain thickness and flatness. And since it's "closed cell foam" I'm also "breaking open the bubbles" so that the epoxy in the carbon fiber that's getting glued over it will adhere better. After I do both sides to thickness, I get to cut the profile: 52475431505__FFC80BBF-09E3-40E9-806C-426B63F2C946.MOV Nice, mindless work for a Friday. ? 1 Link to comment Share on other sites More sharing options...

We mainly machine steel, brass, and aluminum, but we also machine Polyamide-imide and virgin polytetrafluoroethylene for valve seals. Looks like you're using a TiN coated endmill?

Went to their website to see if there was any info about machining it. Basically all it said was "yeah, you can machine it". Gee, thanks. ? Quote Looks like you're using a TiN coated endmill? Yeah, that was the best 1/8" one I happened to have. They buy cheap shit here because the students are rough on stuff. I have my own carbide stash, though. ? 1 Link to comment Share on other sites More sharing options...

We machine seals from round bar, and need to use Tin Carbide because PAI is tough on tooling. HSS just wouldn't do. There are so many plastics (and I use plastic generically) out there. Specifically w/ an infinite number of blends. Link to comment Share on other sites More sharing options...

Specifically w/ an infinite number of blends. Strangest shit I've done so far has been Carbon nanofoam. All the usual sensory type feedback I've used over the years doesn't work with this stuff. You can't come down and touch it with a cutter and feel it. You can be peeling .010 off and there's no sound, very little visual evidence.... Almost impossible to tell when you're touching it, to know how much to cut! It doesn't behave like any metal - it can be springy, but brittle as hell, at the same time.
