摘要/Abstract

摘要： 为了解决传统成型加工过程中304不锈钢材料表面质量差、易产生毛刺等问题，设计了一种新型三维超声振动切削装置并进行了实验研究.首先通过对装置结构几何变形关系的分析，建立了刀尖的理论运动轨迹模型，通过Matlab对轨迹模型进行拟合并利用ANSYS对实际输出轨迹进行仿真分析，得到刀尖运动轨迹为空间中的三维抛物线.其次对装置进行有无超声振动切削实验，通过超景深系统和三维轮廓仪对已加工工件表面进行了测量和观察，发现超声振动切削下已加工表面粗糙度的算术平均高度明显小于普通车削的情况.结果表明:相较于普通车削，超声振动切削对于304不锈钢材料具有良好的加工性能.

Abstract: In order to solve the problems of poor surface quality and easy to produce burrs in the traditional forming process of 304 stainless steel，a new type of three-dimensional ultrasonic vibration cutting device was designed and tested. Firstly，through the analysis of the geometric deformation relationship of the device structure，the theoretical motion trajectory model of the tool tip is established. The trajectory model is fitted by Matlab and the actual output trajectory is simulated by ANSYS. The tool tip motion trajectory is a three-dimensional parabola in space. Secondly，the cutting experiment with or without ultrasonic vibration was carried out on the device， and the machined workpiece surface was measured and observed by the super depth of field system and the three-dimensional profiler. It was found that the arithmetic average height of the machined surface roughness under ultrasonic vibration cutting is significantly lower than that of the ordinary turning. The results show that ultrasonic vibration cutting has better machinability for 304 stainless steel than conventional turning.
