Study on the Effect of Ultrasonic Assisted Grinding Parameters on the Surface Quality and Edge Breakage at Hole Outlet of Microcrystalline Glass
To study the effect of ultrasonic grinding parameters on the surface quality and edge breakage at hole outlet of microcrystalline glass,the ultrasonic amplitude of 3 μm and vibration frequency of 20 kHz were selected in finite element method to analyze the changes of grinding force with the process parameters(feed speed,rotation speed).The force changes of ordinary grinding and ultrasonic grinding under the same process parameters were compared.Then,ultrasonic assisted grinding and ordinary grinding were carried out on five-axis machine tool to compare the surface roughness of the workpiece and the edge breakage at the outlet.The results showed that ultrasonic assisted grinding can significantly reduce the grinding force compared with ordinary grinding,and the experimental results also showed that the small hole edge breakage size under ultrasonic assisted grinding is smaller than that of ordinary grinding.
