Feed in Inches Formula G Code
Free CNC Speeds and Feeds Calculator
Awesome! Free Online Speeds and Feeds Calculator [Mill, Lathe & CNC Router] on this page.
You've found our simple free online Feeds and Speeds Calculator that uses the classic formulas taught in shop class. With a calculator, you don't need to worry about how to calculate feed rate for milling, or the speed (rpms) either. Just key in the parameters and our calculator will find the answer for you.
We offer both that free online feeds and speeds calculator using simple shop formulas, and also a free (for a limited time) full-featured calculator that is the industry leading speeds and feeds calculator. It's used daily by thousands of the world's best manufacturers.
They know what they're doing and wouldn't waste time or money if the software didn't work.
The thing is, why use that simple free calculator when you could grab our full-featured G-Wizard Feeds and Speeds Calculator completely free for 30-days?
How do you lose with that deal?
It takes just 37 seconds to download and start using G-Wizard. It costs you nothing and you can get great feeds and speeds from it for the next 30 days. If you want to go back to our free online calculator after that, no worries.
But you may as well drive the high performance model as long as it's free, right?
