Material removal rate

Material Removal Rate (MRR) is a measure of how quickly material is taken away during manufacturing processes like machining, grinding, or drilling. It indicates the volume of material (such as metal or plastic) removed per unit of time, helping to assess the efficiency of the process. A higher MRR means material is removed faster, which can increase production speed but may also affect surface quality. Conversely, a lower MRR offers precision but might take more time. Understanding MRR helps engineers optimize operations for balance between speed, quality, and tool life.
