摘要:

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.

Abstract:

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 parameters on surface roughness were studied. The model was validated by the experimental results of spherical grinding. The theoretical values agree reasonably well with the experimental results.
 

Key words: spherical grinding, modeling of surface roughness, grinding trajectories, chip thickness
