Material Removal Rate in Machine Tools and Operations Formulas

Material Removal Rate (MRR) is the volume of material removed from workpiece per time unit (usually per minute) when performing machining operations such as drilling. And is denoted by Z_w. Material Removal Rate is usually measured using the Cubic Meter per Second for Volumetric Flow Rate. Note that the value of Material Removal Rate is always positive.
