Default Cutting tips for .02" and .03" Lexan

Hello-

I am about to start cutting .02" and .03" Lexan for face shields. Does anyone have any experience with this? I have not cut this thin of material before and would welcome any tips (bits /feeds/ speeds/ etc..) before I start.

Thanks
Brian

Onsrud O flutes are very good for that application:

I have some upcut ones but for that thin I imagine you could use downcut. They should have speeds and feeds for them

Hi Brian, how did you make out with bits and cutting? What did you end up with feeds and speeds, and hold downs?

Tim and Joey-

Thanks for replying. I have been cutting the shields successfuly using an Amana 45190 (1/16" 2 flute Carbide bit). I ended up cutting two sheets at once at 50 imp and 12k rpm. It takes about 35 minutes to cut two 4'x8' sheets that yield 34 shields per sheet. I am just screwing the sheets down in six spots around the edges which works okay. I have cut around 500 so far. Here is a video I put together on my process.

Thanks
Brian

You have obviously put a lot of time working out your procedure, and put together a very nice product! who would have guessed that a cnc was going to be instrumental in facemasks?? clever Brian!
