摘要: 针对金刚石滚轮修整杯形CBN砂轮时各修整工艺参数对砂轮修整后磨削TC 4时的磨削温度、磨削力和表面粗糙度的影响进行实验研究,并对磨削温度和表面粗糙度进行了多因素回归分析.在回归分析得到的数学模型基础上,进一步对磨削温度和表面粗糙度进行双目标加权优化,得到了粗磨和精磨钛合金时砂轮的最佳修整参数,并通过磨削实验对优化结果进行了验证.

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.
