Setting up a cut?
Enter cut depths and feed parameters to calculate the Material Removal Rate (MRR).
About this calculator
Overview
Material Removal Rate (MRR) measures the volume of material removed from a workpiece per minute. Maximizing MRR without breaking tools is key to efficient machining.
💡
Pro Tips
Ensure your machine has enough horsepower for high MRR cuts.
Chip evacuation becomes critical at high MRR values.

Fun Facts
"MRR is usually measured in cubic inches per minute (in³/min)."
"High Efficiency Milling (HEM) uses a light Radial Depth of Cut (RDOC) but high Axial Depth (ADOC) and Feed Rate to maintain even tool wear."
"Increasing MRR increases power consumption at the spindle."
