摘　　要：分析了内容屑丝锥切削时所产生的切向力和径向力，进而研究了切削力对丝锥切削爪的刚度和强度的影响以及由此对丝锥切齿精度的影响。在此基础上建立了内容屑丝锥优化设计的数学模型并进行了实例计算。利用本文给出的数学模型可以方便地算出在设计内容屑丝锥中难以确定的一些参数。On the principles of metal cutting, this paper analyses the tangential and radial cutting forces developed during cutting by a hollow center tap, furthermore,studies the influence of the cutting forces on the stiffness and strength of tap pawls and whereby on the tooth accuracy of the thread produced.Based on the analysis a mathematical model for the optimum design of the hollow center tap has been developed,and a calculation example has been performed.Using the new approach presented in this paper some parameters which are difficult to determine can be easily obtained.
