超声振动车削是作为一种新的精密切削方法而提出来的。它较好地解决了普通切削中存在的切削阻力大、切削温度高、工件变形大、切削中的自激振动等要害问题,为精密车削和超精密车削提供了一种新的途径。这种切削方法的主要着眼点不是放在提高机床的刚性和精度上,而是放在由超声能所产生的脉冲切削力上。因此它有一套不同于普通切削的新的切削理论和切削方法。超声振动切削在国外一些发达的工业国,例如美、日、苏,都不同程度地用于生产,并取得了较好的技术经济效益。在我国这种精密切削方法也逐渐 Ultrasonic vibration turning is proposed as a new precision cutting method. It solves the key problems of high cutting resistance, high cutting temperature, large workpiece deformation and self-excited vibration during cutting, which provides a new way for precision turning and ultra-precision turning. The main focus of this cutting method is not to improve the rigidity and accuracy of the machine, but rather to impulse cutting forces generated by ultrasonic energy. So it has a set of new cutting theory and cutting method different from ordinary cutting. Ultrasonic vibration cutting in some foreign advanced industrial countries, such as the United States, Japan, the Soviet Union, are used to different degrees of production, and achieved good technical and economic benefits. In our country this precision cutting method is gradually
