【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 most important factors affecting micro milling. A new tool wear prediction model is proposed by combining the constitutive model of materials with the Usui tool wear model and considering the size effect in micro machining. Finite element simulation and physical experiments were used to determine the relevant parameters of the tool wear prediction model in the milling of carbon steel with cemented carbide tools, and the experimental results were verified. In order to observe and predict tool wear more intuitively, the model is applied to the simulation process of micro-milling, and the wear and geometric profile of the tool can be obtained at any time. It provides a new method for the study of tool wear in micro milling.
