Abstract

This paper reviews recent developments of the soft abrasive flow finishing (SAF) method in constraint space. The multiphase fluid dynamics modeling, material removal mechanism, auxiliary strengthening finishing techniques, and observation of surface impact effects by abrasive particles and cavitation bubbles are presented in brief. Development prospects and challenges are given for four aspects: thin-walled curved surfaces, biomedical functions, electronic information, and precise optical components.

概要

本文综述了约束空间内软性磨粒流光整加工(SAF)方法的最新进展。简要介绍了多相流体动力学建模、材料表面加工去除机理、辅助强化光整加工技术以及磨粒和气泡空化对表面冲击效应的观测技术。从薄壁曲面 元件、生物医学功能元件、电子信息及精密光学元件表面超精密加工四个方面给出了软性磨粒流加工技术未来的发展前景和所面临的挑战。
