Hey - used to be a planner and worked a while in a big KD plant so HOOYA. So you didn't illuminate us about what the upcut function in the program does differently. I haven't a clue. Gimme a clue! You did offer a little theory on spin and feed - I've never worked with foam and now I need to without a CNC - just from a template. I'm going to use a trim router in the hand to make simple cutouts of printed poster-size stuff. Haven't done this in a while. It'll be production scale - a few hundred a month. Bet you it's faster.
@@HamiltonDilbeck I used that foam to make some tombstones for the yard last Halloween. I used the wrong spray paint because it did melt tom some degree as you indicated. IN the end, it was OK because it gave the headstones a very weathered/worn look. After carving I used various colors of epoxy for the graphics and lettering. They came out really nice. Thanks for the tip on using non lacquer based though, I may try using this again for other projects that I don't want to look worn.
I cut foam often (xlpe). I always rough pocket with climb, leave a little stock, and finish the walls with conventional. In some foams, a conventional pass will produce long ribbons of material that will wrap around the bit. I run with the highest feeds and speeds I can, only if the material is rigid enough. Softer foam is tricky, so i keep a high chip load but lower the rpms and ipm. There's a risk for melting material. Also, conventional cuts can suck softer material into the cutter and ruin your part.
I always suggest to any new CNC person to start with that foam. It is very forgiving
Very cool. How was the static once you were done?
Great topic Ham! Love this topic. Would be cool to do a sequel with a variety of other foams. Maybe cutting some custom tool inserts for toolboxes?

I may have missed it but did you paint the foam before cutting it to expose the green foam underneath?
yes! any spray paint will work as long as its not lacquer based. Lacquer will melt the foam
