Cutter speeds - where is an authoritative table or formula?

[aliva]

Toms Techniques has a downloadable chart will give a good starting point

I have this under my belt for HSS cutting tools, but I don’t know much about carbide, which I use half the time.

Edit: Apparently you multiply the HSS RPM by a whopping 4 for carbide!

That link to That Lazy Machinist video was appreciated. I hope everybody watches that video. Here are some fun screenshots:

Like many others said, in school they taught us Maximum RPM = (CS X 3.82) / diameter.

There are a lot of apps for your phone.

Take a look at G-Wizard at CNCcookbook.com

speeds and feeds all done in a nice easy app

no table needed.

This looks intriguing...you ca't buy this program, rather, you have to pay a subscription? Are you a member?

Yes I have used it the last couple years. You do the subscription or can buy it lifetime I think. He does ongoing work on it and you can get all upgrades free along the way. I think the price is ok and I like to support someone’s work on a project like that.
