摘　　要：为了研究磨粒对刃口钝化影响,介绍了钝化的实质及磨损的理论,然后用ABAQUS软件对单磨粒与刃口材料的作用进行仿真,结果表明刀具刃口的钝化是固体磨料以一定速度对刃口冲击所造成的材料损耗,影响刃口钝化的主要因素有磨料粒度、硬度、质量和速度等方面。In order to study the influence of abrasive on the cutting edge dulling, the theories about dulling and wear are in- troduced. Effects of single abrasive on cutting edge material are simulated using ABAQUS. The result shows that the dulling of the cutting edge is the material loss which caused by the impact of the solid abrasive at a certain speed. , the main factors that affect the passivation of cutting tool edge are abrasive granularity,hardness ,mass and speed.
