超声振动精密车削加工的试验研究

摘要

分析超声振动精密车削的加工机制，以45钢为例，采用正交试验方法对影响超声振动精密车削质量的因素进行了大量的对比试验研究，确定了对45钢进行精密加工的合理的切削参数，分析了影响表面加工质量的一些因素，同时总结了超声振动车削在精密加工方面的优越性和规律性。%The mechanism of ultrasonic vibration precision turning was analyzed. Taking 45 steel as example,appropriate pro-cessing parameters were gotten through lots of comparative test and orthogonal test,the factors influencing surface roughness were ana-lyzed. Advantages and regularity of ultrasonic vibration in precision turning were summarized.
