摘　　要：丝锥的结构特征决定,在螺纹加工的不同深度,受到的切削力和切削扭矩是不同的,通过分析加工同一个螺纹不同深度的受力情况,在大进给复合式加工方式的前提下使用一套动态变化的加工参数来改善加工的质量和效率,同时以提高加工效率和优化加工质量为目的,并将理论研究和实验相结合,分析得出了后退量的合理范围。The structure of the taps decides that the cutting force and the cutting torque acted upon the tap are different with different depth in thread machining.The through investigating the force situation of the tread in different depth of one work-piece ,then basing on the complex machining fashion with rough feeding, a suit of dynamic parameter is applied to improve quality and efficiency;Meanwhile ,a rational range of recession were analyzed and obtained for the purpose of improving machining efficiency and optimizing machining quality, combining the theoretical study with the experiment.
