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.
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.
