Rpm Calculation Woodweb
Before any calculation is made, you need to know what the motor RPM is at the shaft (either stated on the motor label or taken with a tacho or whatever other means). Once you get that, multiply this RPM by 4 and divide the result by 10 to get the bandwheel RPM (I presume the bandwheel and the 10 inch pulley are on the same shaft).

Cutting Aluminum With A Cnc Router The Hobbyists Guide
Now it’s pretty unlikely that you have a 96,000 RPM machine, but this should give you an idea of how cutter diameter affects RPM. If your minimum speed is 30k RPM, then you might want to shy away from 1/4″ endmills for aluminum in favor of something 3/16″ or 1/8″. Some say that to reduce the “required” RPM, you need to use a HSS cutter.

The whole feeds & speeds topic is arguably the most daunting part of learning CNC. Feeds is feedrate, on some CNCs with a fixed tool and moving plate this is the speed at which the material is fed into the cutter, on a Shapeoko this is the speed of the gantry pushing the cutter into the material. Speeds is the rotation speed of the endmill, i.e. RPM value.
