摘要

In order to study the influence of ultrasonic vibration and grinding on EDM, this paper analyzes the surface quality and machining efficiency of EDM under the effect of ultrasound and grinding by carrying out ultrasonic vibration-assisted EDM grinding research on aluminum materials. Based on the heat transfer theory, an EDM heat transfer model for ultrasonic grinding combining ultrasonic vibration and grinding characteristics is established, and the effects of ultrasonic vibration amplitude, grinding wheel speed, and current on the response of surface roughness and material removal rate are experimentally investigated. The results show that ultrasound-assisted EDM grinding process can improve the material removal rate and surface quality compared with the traditional EDM grinding process. In both EDG and UVEDG machining, the increase of current increases the machining center temperature and material removal, and the addition of ultrasound-assisted amplitude reduces the maximum center temperature of UVEDG and decreases the pit size; under specific conditions, the material removal rate of UVEDG is significantly affected by current, amplitude, and rotational speed. At the same time, the surface roughness of UVEDG is reduced by increasing the rotational speed, and the surface roughness increases and then decreases when the current is changed, and the EDM craters on the machined surface of UVEDG are fewer than those of EDG, so increasing the amplitude reduces the craters and improves the stability of the machining and the surface quality of the workpieces.
