摘　　要：梯形螺纹切削加工始终是机械制造行业的热点和难点。概述了螺纹加工的常用方法,列举了梯形螺纹切削加工要点,尤其是详细分析了车刀的角度处理,关键因素包括切削力的减小、左右移动切削的实现、刃前角和刀尖角的校正等。通过Fanuc数控系统的B类宏程序进行参数化编程,最终实现了梯形螺纹的切削加工效率和质量共同提升。Cutting process of trapezoidal thread is always a hot and difficult topic in the machinemanufacturing industry.Commonly used methods of thread processing are summarized,core points ofcutting process of trapezoidal thread are listed,and especially,a detailed analysis turning angle of the toolis put forward,showing that the decrease on cutting force,implement on move-around stratified cutting,and calibration of rake angle and sharp angle,are all essential.Through parametric programming of FanucCNC system B macro,finally realized are the win-win on efficiency and quality of cutting process oftrapezoidal thread.
