17.2.1 Definition of Engineered Grinding Wheel
Precision grinding can obtain workpiece with high surface quality and high precision (Dold et al., 2011; Guo et al., 2017; Jia, Li, Zhang, Zhang, & Zhang, 2014; Jia, Li, Zhang, Zhang, & Zhang, 2016; Xu et al., 2019), it is usually taken as the final part machining procedure, but random distribution of abrasive grains on the grinding wheel surface poses a certain difficulty to improvement of machining precision and quality (Koshy, Iwasald, & Elbestawl, 2003; Ren & Hua, 2011). In order to solve the above problem, Canadian scholar P. Koshy (Chen, Wang, Yushan, Liu, & Wang, 2015; Heinzel, Rickens, & Trumpold, 2009; Koshy et al., 2003) proposed the concept of engineered grinding wheel in the 53rd CIRP annual meeting, namely grinding wheel manufactured according to manually set spatial distribution matrix and protruding height of abrasive grains with the same size.
