Optimizing Material Removal Rates - In The Loupe

Calculating MRR. The calculation for Material Removal Rate is RDOC x ADOC x Feed Rate. As an example, if your RDOC is .500″, your ADOC is .100″ and your Feed Rate is 41.5 inches per minute, you'd calculate MRR the following way: MRR = .500″ x .100″ x 41.5 in/min = 2.08 cubic inches per minute.
