The grinding tests were performed on a MM7120A precision grinder (see Fig. 5). Before grinding, the dynamic balancing of all grinding wheels was confirmed, and the workpieces were pre-machined with a 1 mm cut to remove any surface irregularities and ensure similar surface properties for all specimens. The dressing operation was maintained ...

The surface damage induced by diamond grinding are shown in Fig. 7. Owing to material softening induced by the thermal energy, plastic deformation of the bulk material occurred under the diamond grinding action. Although the dominant type of surface damage was fracture, ductile grinding tracks were visible at the three discharge-energy levels.
