Calculating the RPM for your machines

Here's how to calculate the proper RPM of your machines for a given material and diameter. I explain how cutting speeds are represented (in both Surface Feet per Minute and Meters per Minute), talk a bit about the materials and cutting tools, and show examples of the equations.
