Micro grinding tool for manufacture of complex structures in
Grinding tests show that the micro grinding tools are capable of ultra precision grinding. Micro structured surfaces in optical quality are generated in carbide by In micro-grinding, the effect of material microstructure on residual stress is significant since the depth of cut is usually smaller than the average grain size. In this paper, the effect of crystallographic orientation (CO) on the distribution of residual stress induced by micro-grinding is investigated. The COs and their volume fractions of workpiece material Effect of crystallographic orientation on residual stress
