摘　　要：重复切削是分离式振动攻丝的一个重要特性,它不仅能够抑制已加工表面回弹、降低攻丝扭矩,而且影响内螺纹的牙型精度。在对分离式振动攻丝运动原理进行简要分析的基础上,本文主要研究了重复切削对螺纹牙型精度的影响规律,并进行了试验验证。理论和试验证明重复切削对螺纹精度的影响,为加工出精密的内螺纹打下基础。Repeat cutting can restraint the surface spring-back, reduce tapping torque when processing the inner screw. But the cyclical repeat cutting is bound to affect to the accuracy of inner screw.based on kinematical principle of the separable vibration tapping,the paper study the surface forming mechanism of the separable vibration tapping and how repeat cutting affecting on the processing accuracy of inner screw and verify it by the experiment. the theory and experiment prove that repeat cutting affect on accu...
