Very useful, but I would like to see recommended Chip Load tables for the tooling. Feeds and Speeds are variables, but chip load is a relative constant per tool.
I could take these tables and let MillMage compute the chip load, then record each for the tooling I have, but where is the fun in that?
Never mind, I found one.
I cleaned it up, add some math and a chart, and PDF’ed it. Remove the .txt to use after downloading.

Thanks for this as it looks like they disabled the link.

I found this to be a better entry point link for what @parsec offers.
A list of materials that can be cut by most hobby CNC, with considerations for cutting tools and best practices. Wood, plastic, foam and soft metal suggested.

I saved all that page yesterday late in the night. I usually do as .PDF or .html when the pages have some interesting info.
