本文提出了一种三维有限元方法，将微观结构的微切削模拟的基础上的概念，一个代表性的体积元（RVE）和本构材料建模，以及使用隐式有限元程序Deform 3DTM中提出的拉格朗日公式。采用不同切削参数的整体硬质合金刀具对铁素体-珠光体两相钢AISI 1045进行精拉、微铣削和微钻削试验，验证了所建立的三维多相切屑形成和切削力有限元计算模型。开发的三维多相有限元模型被成功地用于预测微切削的尺寸效应。
This paper presents a three-dimensional finite element approach to incorporate microstructure into micro cutting simulation based on the concept of a representative volume element (RVE) and constitutive material modeling as well as using the Lagrangian formulation proposed in the implicit FE code Deform 3DTM. Finish broaching, micro milling and micro drilling tests using solid carbide tools with different cutting parameters are performed on ferrite-pearlite two-phase steel AISI 1045 for the verification of the developed 3D multiphase FE computation model regarding chip formation and cutting forces. The developed 3D multiphase FE model is successfully used to predict size effects in micro cutting.
