Metal Removal Rate

Calculate the volume of material removed per minute.

Total MRR

in³/min
Formula Used

The standard formula for calculating MRR in milling operations is:

MRR = Width × Depth × Feed
  • Width: The radial engagement of the tool.
  • Depth: The axial depth of the cut.
  • Feed: The linear travel speed of the tool.
Current Units:
Imperial: in × in × in/min = in³/min
Improving MRR usually involves increasing depth of cut or feed, but watch your machine's horsepower limits!
