Material Removal Rate Material removal rate (MRR) refers to the volume or mass of material removed from a workpiece or substrate during a specific machining, cutting, or material processing operation. It is a measure of the efficiency and productivity of the manufacturing process and is typically expressed in units such as cubic millimeters per minute (mm³/min), cubic inches per minute (in³/min), or kilograms per hour (kg/h).
Material removal rate depends on various factors, including cutting parameters, tool geometry, cutting speed, feed rate, depth of cut, material properties, and machine tool capabilities. Maximizing material removal rate while maintaining quality and accuracy is a key objective in machining, milling, turning, grinding, and other material processing operations, as it directly impacts productivity, cycle times, and production costs. |
