Force prediction model considering material removal mechanism for axial ultrasonic vibration-assisted peripheral grinding of Zerodur

摘要: Axial ultrasonic vibration-assisted peripheral grinding (AUPG) has the major advantages of simultaneously improving quality and material removal rate compared with conventional methods. In this study, a force prediction model for AUPG Zerodur was developed to investigate generation mechanism guidance in practical engineering applications. Taking into consideration mechanism, properties vibration impact, three primary components were first separately modelled, namely, ductile phase, brittle phase frictional friction process. The critical uncut chip thickness maximum subsequently researched define two modes Zerodur, mode mixture mode. models these using effective component models. instantaneous variation time space also analysed derive final time-averaged normal force, tangential axial force. Finally, experiments performed, results which showed that errors only 7.37 11.53% forces, respectively. determined reduce surface roughness by 18.0% grinding, while forces reduced 27.31 22.52%, This indicates affords significantly improved quality. enables an understanding comprehensive provides basis development other materials.
