2013年1月1日 A greater grinding force leads to a larger edge chipping size (as shown in Fig. 12), because the down-feedrate is increased [14]. In addition, the higher down-feedrate also aggravates the impact between the wafer edge and the grinding wheel due to the tooth segment design of grinding wheel, which will increase the edge chipping size.
