- 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.
