超声振动切削超薄壁精密零件的圆度误差试验研究

Research on roundness error of precise ultra-thin wall parts in ultrasonic vibration cutting

试验研究了超声振动车削直径为47.75mm壁厚为0.8-1.5mm的照相机导向筒超薄壁精密零件的圆度形成规律及切削参数对圆度误差的影响。研究表明:超声车削精密超薄壁零件,圆度误差最小是普通精密切削的1/3。

In the paper, the experimental researches were carried out on the roundness forming rule and the influence of cutting parameters on roundness by ultrasonic vibration cutting of the camera's guiding drawtube with 47.75mm diameter and 0.6 - 1. 5mm wall thick-ness.The research results show that the roundness error of ultra-thin wall parts in ultrasonic vibration cutting is only third of that in common cutting.
