摘要

刀具磨损是影响微细铣削加工的重要因素之一，将材料的本构模型与Usui刀具磨损模型相结合，并考虑到微细加工中存在的尺寸效应，提出一种新的刀具磨损预测模型，采用有限元仿真和物理实验的方法确定硬质合金刀具铣削碳钢时刀具磨损预测模型中的相关参数，并进行了实验验证。为了更直观的观察、预测刀具磨损情况，将该模型应用于微细铣削仿真过程中，可求得任意时刻刀具的磨损及几何轮廓。为微细铣削中刀具磨损的研究提供了新的方法。

Abstract

Tool wear is one of the important factors that affect the micro milling process.Combining the constitutive model and Usui tool wear model,and considering the size effect during micro machining,a new tool wear prediction model was proposed.The relevant parameters of the prediction model for the micro milling of carbon steel workpieces by tungsten carbide tools were determined by the finite element simulation and physical experiment,which were then verified by further experiments.In order to observe and predict the tool wear more apparently,the prediction model was applied yet to a micro milling process simulation,so as to obtain the tool wear and its geometrical shape at any time in the proccss.The study provides a new method for studying the tool wear during micro milling.
