    摘要:

    以MJ-9159炸药模拟材料超声振动车削及数字共聚焦表面微观形貌测量为试验基础, 针对炸药材料较差的加工性及对力和温度冲击的敏感性, 研究了超声振动车削的切削机理, 对比分析了普通车削和超声振动车削以及2, 3.4, 5 μm振幅超声振动车削模式对加工表面质量的影响。结果表明, 超声振动车削表面质量优于普通车削。基于应力波作用的断屑方式, 使用分离式超声振动切削状态即转速60 m·min-1、振幅5 μm时车削表面质量最好。

    Abstract:

    In view of the poor workability of explosive materials and its sensitivity to force and temperature shock, and using the ultrasonic vibration turning the MJ-9159 explosive simulants and digital confocal surface microscopic morphology measurements as the foundation of test, the ultrasonic vibration turning mechanism was studied and the effects of the common turning and the ultrasonic vibration turning mode with amplitude of 2, 3.4, 5 μm on the machined surface quality were compared and analyzed. The results show that ultrasonic vibration turning surface quality is better than that of common turning. Based on the stress wave effect, when the separate state of ultrasonic vibration turning is the speed 60 m·min-1 and amplitude 5 μm, the turning surface quality is best.
