摘要: 随着航空航天、生物医疗等领域对高端装备中使用的复合材料零部件的制造需求跨越式提升,金属基复合材料(Metal matrix composites, MMCs)切削加工性能研究成为学术界和工业界持续关注的热点之一。近年来众多学者在MMCs切削过程分析方面已开展大量研究并取得丰富成果,但仍缺乏从MMCs组织和性能角度总结材料去除机理和切削过程建模的研究进展,特别是针对微细切削加工研究的报道较少。本文重点分析不同加工尺度下增强相特征参数对MMCs去除机理的影响,探讨MMCs的微尺度去除机理。此外,还对切削过程建模研究进行了综述,包括本构关系与切削力的解析建模、切屑成形过程有限元仿真模拟和原位观测分析,重点总结了材料多相结构、增强相脱粘与断裂行为以及强化机制和尺度效应等机理在建模中的体现,为微细切削过程建模提供重要指导。最后,对MMCs切削过程研究进行了总结和展望,为解决MMCs微细/精密切削加工难题提供理论和数据支撑。

Abstract: With the leap forward in the manufacturing demand for composite parts in high-precision equipment in aerospace, biomedical and other fields, the research on the machinability of metal matrix composites (MMCs) has become one of the hot spots of continuous attention in academia and industry. In recent years, in the study of MMCs cutting process, many academics have done extensive research and produced a wealth of findings. However, not enough study has been done to summarize the material removal mechanism and machining process modeling from the perspective of the material microstructures and properties, especially for the micro-scale machining of MMCs. This paper will focus on the influence of the characteristic parameters of reinforcements on the MMCs removal mechanism at different machining scales and explore the micro-removal mechanism of MMCs. In addition, a review of cutting process modeling studies is also presented, including analytical modeling of the constitutive relationship and cutting forces, finite element simulations of chip formation process and in-situ observation analysis. The emphasis is on outlining how the material multiphase structure, reinforcement debonding and fracture behavior, as well as strengthening mechanisms and size effects and other mechanisms reflected in modeling, which provide important guidance for modeling of micro-scale machining process. Finally, the research on the MMCs cutting process is summarized and prospected to provide theoretical and data support for solving the difficulties in micro-scale/precision machining of MMCs.

Key words: metal matrix composites, material removal mechanism, cutting process modeling, ceramic reinforcements, microstructure and properties
