A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

This is a calculator for computing the correct feeds and speeds (RPM and IPM) for milling machines. It differs from other online calculators because it is an OPTIMIZING calculator -- each parameter has a range from minimum to maximum. The calcuator searches for the best cut (maximizing MRR) while keeping all parameters within the range you specify.

As the degree of taper increases, you may have to use the large diameter provided to calculate the appropriate RPM, instead of tip size. This usually isn't necessary until seven degrees. At that time, the tip size would be used to calculate the needed feed per tooth. Tapered end mill usage can be tricky if the proper settings are not adhered to.
