MRR — depth of cut × width of cut × feed rate — is the key efficiency metric for any cutting operation. Use it to compare tooling strategies, estimate cycle time, or check if you’re close to spindle horsepower limits.
Milling MRR = axial DOC × radial WOC × feed rate (IPM).
Turning MRR = 12 × cutting speed (SFM) × depth of cut × feed per rev (in³/min).
Turning MRR = 12 × cutting speed (SFM) × depth of cut × feed per rev (in³/min).
