Abstract�� Influences of dressing parameters on grinding temperatures, grinding forces and surface roughness in grinding TC 4 with cup-shaped CBN wheels dressed with a diamond roller under dry condition were investigated through experiments. Grinding temperatures and surface roughness were analyzed adopting regression method. Based on the mathematical models obtained by regression, weighted double-objective optimization was performed for lower grinding temperature and lower surface roughness. Finally, the optimal dressing parameters were calculated respectively for rough grinding and finish grinding and verified through grinding TC 4 experiments.
Keywords�� diamond roller   vitrified CBN wheel   dressing parameters   regression analysis   weighted double-objective optimization
