球面磨削表面粗糙度的仿真研究

Modeling and Simulation of Surface Roughness for Spherical Grinding

在未变形切屑厚度模型的基础上,考虑多磨粒轨迹叠加作用对磨削表面质量的影响,建立了球面磨削表面粗糙度的预测模型,并对影响球面磨削表面粗糙度的因素进行了理论分析和实验研究.结果表明,基于球面粗糙度数学模型的理论分析结果与实验结果较吻合,从而验证了所建立的球面磨削表面粗糙度模型的正确性.

A new analytical surface roughness model was developed on the basis of chip thickness model considering the effect of overlapping of multiple abrasive particles. The influences of grinding process pa- rameters on surface roughness were studied. The model was validated by the experimental results of spher- ical grinding. The theoretical values agree reasonably well with the experimental results.
