纵扭超声振动辅助钻削氧化铝陶瓷研究
Research on Longitudinal-torsional Ultrasonic Vibration Assisted Drilling of Alumina Ceramics
摘要
Abstract
In order to solve the problem of difficult processing of alumina ceramics,the longitudinal-torsional ultrasonic vibration assisted drilling method is adopted to conduct experimental research.Modify ordinary drilling machine tools,add ultrasonic vibration mechanisms,change spindle speed and ultrasonic amplitude on the machine tool,and process alumina ceramic materials.By analyzing the morphology of ceramic workpieces and the degree of tool wear under different parameter conditions,combined with finite element simulation,the feasibility and advantages of longitudinal-torsional ultrasonic vibration assisted drilling are confirmed.The results show that compared with ordinary drilling,alumina ceramic materials processed by longitudinal-torsional ultrasonic vibration assisted drilling have better surface morphology,and the processed holes have lower surface roughness.As the amplitude increases,the degree of tool wear also decreases significantly,but it is not necessarily better to have a larger amplitude.When the amplitude is too large,the degree of tool wear intensifies.Longitudinal-torsional ultrasonic vibration assisted drilling is not suitable for high spindle speeds.When the speed is too high,the workpiece is prone to fracture and it is difficult to complete the machining.In summary,with proper selection of process parameters,longitudinal-torsional ultrasonic vibration assisted drilling can achieve high-quality processing of alumina ceramics.关键词
