I need to cut a Plexiglass backlighting panel for an address plaque I’m building as my first real project, and I’m looking for a good feed rate.
For starters, I programmed it at .020 deep per pass @ 20 IPM to cut out a 3/16" thick panel. Haven’t run it through a feed and speed calculator being this stuff is a little tricky to cut. Figured I’d start here and look for advice, and tweak my programming accordingly based on what y’all know to work.
I have 3 single flute carbide cutters, and was going to use the 1/4" cutter. I’ve also got 1/8 & 3/16 cutters I can use if they work better. I figured the larger flute of the 1/4 cutter would help evacuate material quicker to prevent melting.
I’ve cut Plex and Lexan manually on the Bridgeport, but I know that’s a different animal. We left the paper backing on to help keep the edges from chipping once the cutter breaks through, and cut it low and slow with lots of WD40 to lubricate. Trying not to use WD here though so I don’t screw up my MDF spoil board.
Any advice would be appreciated!
