Jan 15, 2018 · Material Removal Rate (MRR), otherwise known as Metal Removal Rate, is the measurement for how much material is removed from a part in a given period of time. If you're aiming to boost your shop's efficiency, increasing your MRR even minimally can result in big gains.

= 50-150 m/s the material removal rate per unit active grinding wheel width Qw' = 50 mm3/mm·s is obtained, when a coolant is delivered to the grinding zone from the inside of grinding wheel by channels under pressure of 30 bar and by the nozzles from the outside of grinding .

[PDF]Material removal rate in grinding is usually quoted in terms of removal rate per unit width of grinding contact. Removal rate per unit width is known as specific removal rate Q′. Using the specific removal rate reduces the number of variables and allows direct comparison of removal efficiency across a wide range of operations (Fig. 2.7).
