本文将基于有限元的刀具磨损仿真应用于复杂形状和涂层刀具的车削加工。涂层被认为是一个具有特定摩擦和热性能以及耐磨性的功能层。因此，一个修改后的EQUIRI工具磨损模型被校准的涂层和基板，并结合在一个三维模拟，以模拟磨损过程，包括裸露的基板与局部的热，摩擦和磨损性能的变化。研究了用PVD-TiAlN涂层和未涂层硬质合金刀具车削AISI 1045的情况。仿真结果验证了模拟磨损和外部纵向车削实验的广泛领域的切削参数的比较。(C)2015 Elsevier B.V.版权所有。
this paper FE-based tool wear simulation has been applied to complex shaped and coated cutting tools in turning operations. The coating has been considered by an own functional layer with specific friction and thermal properties as well as wear resistance. Therefore, a modified Usui tool wear model is calibrated for the coating and the substrate and combined in a three-dimensional simulation in order to simulate the wearing process including the baring of the substrate with a change in local thermal, friction and wear properties. Turning of AISI 1045 with PVD-TiAlN-coated and uncoated carbide tools was considered. The simulation results are validated by a comparison of simulated wear and external longitudinal turning experiments for a wide field of cutting parameters. (C) 2015 Elsevier B.V. All rights reserved.
