Abstract

Aluminum alloy (Al6061) is a common material used in the ultraprecision area. It can be machined with a good surface finish by single-point diamond turning (SPDT). Due to the material being relatively soft, it is difficult to apply post-processing techniques such as ultraprecision lapping and ultraprecision polishing, as they may scratch the diamond-turned surface. As a result, a novel low-pressure lapping method was developed by our team to reduce the surface roughness. In this study, a finite element model was developed to simulate the mechanism of this novel lapping technology. The simulation results were compared with the experimental results so as to gain a better understanding of the lapping mechanism.

摘要

铝合金（Al6061）是超精密领域常用的材料。通过单点金刚石车削（SPDT）可以加工出具有良好表面光洁度的铝合金。由于该材料相对较软，难以应用超精密研磨和超精密抛光等后处理技术，因为这些技术可能会划伤金刚石车削表面。因此，我们团队开发了一种新型低压研磨方法来降低表面粗糙度。在本研究中，建立了有限元模型来模拟这种新型研磨技术的机理。将模拟结果与实验结果进行比较，以便更好地理解研磨机理。
