Hi there,
I am looking for some help with Feeds and Speeds on Plastics and Thin Gauge Aluminum. Plastics are acrylic, ABS, PVC, PolyCarbonate, HDPE and UHMW. I also need some on .060 aluminum. Any help would be great. Thank you.
Cheers,
Jeff

Best would be to check the web site of the manufacturer of the cutting tools you are using.

For plastics and thin aluminum I really like Onsrud cutters. Their single flute cutters work great on plastics and they have recommended feeds and speeds on their site. Even if you are using different cutters that will at least start you in the right ballpark.

The main issue with cutting plastics, especially with a fast turning router is too low a chip load. That causes the plastic to melt and build up on the cutter. If your plastic is melting turn down the spindle RPM or increase the feed rate.

I have also recently started using Gwizard for feeds and speeds and found it very good. They have a 30 day free trial on their web site. Good luck and have fun.
