【摘要】：刀具磨損是影響微細(xì)銑削加工的重要因素之一,將材料的本構(gòu)模型與Usui刀具磨損模型相結(jié)合,并考慮到微細(xì)加工中存在的尺寸效應(yīng),提出一種新的刀具磨損預(yù)測模型,采用有限元仿真和物理實(shí)驗(yàn)的方法確定硬質(zhì)合金刀具銑削碳鋼時(shí)刀具磨損預(yù)測模型中的相關(guān)參數(shù),并進(jìn)行了實(shí)驗(yàn)驗(yàn)證。為了更直觀的觀察、預(yù)測刀具磨損情況,將該模型應(yīng)用于微細(xì)銑削仿真過程中,可求得任意時(shí)刻刀具的磨損及幾何輪廓。為微細(xì)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.
