【摘要】：刀具磨損是影響微細銑削加工的重要因素之一,將材料的本構模型與Usui刀具磨損模型相結合,并考慮到微細加工中存在的尺寸效應,提出一種新的刀具磨損預測模型,采用有限元仿真和物理實驗的方法確定硬質合金刀具銑削碳鋼時刀具磨損預測模型中的相關參數(shù),并進行了實驗驗證。為了更直觀的觀察、預測刀具磨損情況,將該模型應用于微細銑削仿真過程中,可求得任意時刻刀具的磨損及幾何輪廓。為微細銑削中刀具磨損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.
