| 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 |
