摘要

表面质量的不稳定和意外振动是冶金锯片切割过程中存在的严重问题，经常导致大量的废料或刀具损坏。本文利用ABAQUS软件建立了基于正交切削法的有限元模型，研究了铣削参数对切削过程的影响。引入Johnson-Cook热粘塑性效应，对切屑形貌和应力状态的模拟结果与实际生产情况基本一致。通过不同参数的仿真，验证了切削力和切削温度随刀具切削速度和切削厚度的变化规律。据此提出了合适的切削参数大小。

Finite Element Analysis of Milling Parameters for Metallurgy Saw Blade Cutting Process

Unsteadiness of surface quality and accidental vibration are serious problem in metallurgy saw blades cutting process that often lead to lots of waste products or causing tools damage. This paper, using ABAQUS software, develops an FEM model based on the orthogonal-cutting method to investigate the impact of milling parameters upon cutting process. Introducing to the Johnson-Cook thermal visco-plastic affects, the simulation results of the chip morphology and the stress state accord with that in real production. Simulation by varied parameters demonstrate the regularity of cutting force and cutting temperature for the change of cutting speed and cutting thickness of the cutter. And thus, suitable magnitude of cutting parameters are suggested.
