摘要
文摘分析旋转超声加工材料去除机理,建立材料去除效率模型,探讨工艺参数对加工效率的影响规律;对压电陶瓷、有机玻璃、玻璃钢、紫铜等多种材料,进行单一超声和旋转超声加工材料去除效率对比试验,研究旋转超声加工方式对加工过程稳定性及加工效率的影响。结果表明:旋转超声加工可在保持原超声加工精度基础上,显著提高材料加工效率,且对较难超声加工材料(如有机玻璃),旋转超声提高其加工效率的效果更为显著。
Through analyzing material removal mechanism of rotary ultrasonic machining,a model of machining efficiency is established and the processing parameters in the model are discussed in this article. By comparing four different materials inclding PZT piezoelectric ceramics,organic glass,glass steel and red cooper on single ultrasonic and rotary ultrasonic machining testing,the machining stabilization and efficiency of rotary ultrasonic are studied.The tests prove that rotation can significantly improve ultrasonic machining efficiency and keep the original precision.
