Material Removal Rate an overview ScienceDirect Topics
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).
