摘要
建立了微磨削过程的传热模型,针对石英玻璃材料进行有限元仿真分析,探讨了微磨削过程中磨削热的分布情况,分析磨削用量对磨削温度的影响规律.利用粒度500#的微磨具对石英玻璃进行单因素磨削温度测量实验.仿真与实验结果表明:磨削区表面最高温度随切削深度的增大而升高,随磨削速度的加快而升高,实测最高磨削区温度仅为94.2℃,并没有出现磨削烧伤现象.
To investigate the effect of different grinding conditions on micro-grinding temperature, the heat transfer model in micro-grinding process was established and the finite element simulation analysis was conducted to study the temperature distribution in micro-grinding quartz glass. The single factor experiments with quartz glass were conducted by micro-grinding tools with size 500#. The influence of different grinding factors on micro-grinding temperature was analyzed. The simulation and experimental results show that the highest surface temperature of the grinding zone increases with the increase of cutting depth and grinding speed, and the measured highest temperature in the grinding zone is 94. 2℃ without grinding burning.
