Material Removal Rate
Material removal rate (MRR) in cubic inches per minute for milling (WOC x DOC x feed_IPM).
Example
You enter
- Operation milling
- Width of cut WOC (in, milling) 0.5
- Depth of cut DOC (in, milling/turning) 0.1
- Feed rate (IPM, milling/drilling) 10
You get
- Material removal rate 0.5
- Mrr cm3 8.19353
Details, formula, and sources
Turning (12 x SFM x DOC x feed_IPR), or drilling ((pi x D^2 / 4) x feed_IPM) (first-principles swept-volume geometry).
Milling MRR = WOC x DOC x feed_IPM; turning MRR = 12 x SFM x DOC x feed_IPR (the pi x D cancels); drilling MRR = (pi x D^2 / 4) x feed_IPM, in in^3/min.
Material removal rate as the swept volume per unit time - first-principles geometry as in Machinery's Handbook (Industrial Press), by name; public domain.
Pure geometry, public; the machine rigidity, power, and chip-load limit cap the usable rate.
Estimate. AHJ and licensed professional govern.
