磨削液供给参数对工件表面完整性的影响

摘要/Abstract

摘要： 针对不同磨削液供给参数，通过CFD软件构建磨削过程中磨削区处气-液两相的磨削液喷射模型，并对喷嘴的喷射参数进行仿真与计算。通过比较不同喷射速度、喷射方位和喷射角度对磨削液流场的质量流量的影响，以及它们对喷射过程中磨削液在整个磨削区的体积分数的影响，来确定合理的喷嘴喷射方位。最后通过磨削液喷射角度对工件表面完整性影响的试验研究，为确定相对合适的喷嘴方位提供试验依据，验证磨削加工过程中磨削液供给参数选择的合理性。

Abstract: According to the different parameters of grinding fluid supplyies, gas and liquid phase of jet flow model of grinding zone in the grinding processes was established by using CFD software. And the jet parameters of grinding machine nozzle were simulated and calculated. Through the comparison of the effects of jet speeds, jet directions and jet angles on mass flow rate of grinding fluid flow field and the volume fraction of jet flow process in the grinding zone, the most reasonable nozzle jet would be determined. At last, the experimental studies of workpiece surface integrity were used to provide experimental basis to determine the most suitable nozzle positions and verify the rationality of the grinding flow supply parameter selection in the grinding processes.

Key words: grinding fluid, airflow, supply parameter, nozzle, surface integrity
