Study on Ultrasonic Vibration Assisted Polishing Force and Surface Quality of CoCrMo Alloy
Aiming at the difficult processing of CoCrMo alloy,the processing method of ultrasonic vibration assisted polishing is used to improve the processing effect.According to the motion characteristics of the ultrasonic vibration device,the speed of the single abrasive particle,the coordinate of the contact track between the single abrasive particle and the workpiece,and the force of the single abrasive particle are analyzed,and the polishing force prediction model for the polishing system is established.The effects of the spindle speed,feed speed and polishing depth on the surface quality of CoCrMo alloy are discussed and the validity of the prediction model is verified by experiments.The results show that the polishing force prediction model is consistent with the experiment.The polishing force increases with the increasing of spindle speed and polishing depth,and decreases with the increasing of feed speed.This research will provide a theoretical basis for the ultrasonic vibration-assisted polishing process.
