Feeds, Speeds, and Chiploads For A Small CNC Made Easy

CNC feeds and speeds aren't the same for every machine. Bit manufacturers provide suggested feeds, speeds, and chip loads. That's all well and good if your machine is industrial and can run 750ipm +. Entry level machines won't run at these recommended specs.

You could always use the special formula (rpm x # of flutes x chip load) to find your feed rate, which will likely well exceed what an entry level machine can operate at. Or, you can make adjustments like I did and dial in the sweet spot for your home shop machine.

It's not an impossible and doesn't require a mathematical degree. Check out how I dialed in the running specs for my Shark HD5
