摘　　要：聚碳酸酯具有某些金属材料的性能,能够承受一定的外力,具有良好的机械性能并运用广泛。由于聚碳酸酯属于难加工材料,在加工过程中不易被切削。本文通过参数化建模,建立了聚碳酸酯超声振动车削(UVT)的有限元模型,选择合适的材料、参数及角度,建立了能够反应不同车削速度以及多种工况的有限元模型。观察在不同车削速度下聚碳酸酯材料与刀具接触点温度曲线以及温度场的变化,对聚碳酸酯微观表面进行分析。Polycarbonate has the properties of some metal materials,can withstand certain external force,has good mechanical properties.So it is widely used.Polycarbonate belongs to difficult-to-machine material,it is not easy to be cut in machining process.Through the parameterized modeling,finite element model of the ultrasonic vibration turning(UVT)is built up.By electing the appropriate materials and parameters,finite element model which can respond different cutting speed and various working condition is established.The temperature curve of contact point between polycarbonate and tool and the change of temperature field are observed,the micro surface of polycarbonate is analyzed.
