摘要: 为了进一步改善切削性能,将微织构刀具应用于椭圆超声辅助切削过程中,分析其对切削力、刀具磨损及表面质量的影响,然后分析刀具表面微织构角度与尺寸对刀具磨损的影响规律。研究结果表明:微织构刀具可以在保留椭圆超声辅助切削优异性能的基础上进一步改善切削性能,而且根据实验结果,微织构角度与尺寸变化会影响刀具抗磨损效果,当微织构与主切削刃平行、宽度为70 μm、间距为70 μm时,刀具黏结磨损最小。

Abstract: In order to further improve the cutting performance, the micro texture tool was applied to the elliptical ultrasonic assisted cutting processes, and the influences on cutting force, tool wear and surface quality were analyzed. Then the influence laws of tool surface micro texture angle and size on tool wear were analyzed. The results show that the micro texture tool may further improve the cutting performance while retaining the excellent performance of elliptical ultrasonic assisted cutting, and according to the experimental results, the change of micro texture angle and size will affect the wear resistance of the tool, when the micro texture is parallel to the main cutting edge and the width is as 70 μm, spacing is as 70 μm, the tool bond wear is the smallest.

Key words: elliptical ultrasonic assisted cutting, micro-texture tool, cutting performance, micro-texture angle and size
