摘要

摘要: 针对磨削加工过程中磨削温度高、表面质量差以及砂轮使用寿命低等问题，从运动学和切削力两方面分析了切向超声辅助磨削加工机理。以Ti6Al4V为工件材料，通过对比实验研究了超声振幅、磨削深度、进给速度与主轴转速对材料表面粗糙度的影响。实验结果表明：与单一磨削加工相比，引入超声振动后材料表面粗糙度Ra降低25%～40%，材料表面凹坑明显减少，表面形貌发生显著变化。随着振幅的升高材料表面粗糙度减小，最大降幅为40%；粗糙度随着转速的升高而降低，降低幅度为25%。证明了超声振动的引入可以减小粗糙度，提高磨削加工工件的表面质量。研究结果为磨削加工中参数的选择提供指导意义。

Abstract: Aiming at the problems of high grinding temperature, poor surface quality and low service life of grinding wheel in grinding process, this paper analyzed the mechanism of tangential ultrasonic assisted grinding from two aspects of kinematics and cutting force. Taking Ti6Al4V as workpiece material, the influences of ultrasonic amplitude, grinding depth, feed speed and spindle speed on material surface roughness were studied through comparative experiments. The experimental results show that, compared with the single grinding process, the surface roughness Ra is reduced by 25%～40% after the introduction of ultrasonic vibration, the surface pits are reduced significantly, and the surface topography changes significantly. With the increase of amplitude, the surface roughness of the material decreases by 40%. The roughness decreases with the increase of rotational speed by 25%. It is proved that the introduction of ultrasonic vibration can reduce the roughness and improve the surface quality of grinding workpiece. The results provide guidance for the selection of grinding parameters.
