机用丝锥的计算机辅助设计

Computer Aided Design of Machine Taps

丝锥主要用于加工内螺纹,手工设计丝锥费时费力且易出错。为了提高丝锥的设计效率、减轻劳动强度和节约企业成本,应用计算机辅助设计方法,将可查参数设计的标准丝锥与不可查参数的非标丝锥整合,进行计算机辅助设计。以丝锥切削扭矩最小为设计目标,通过设定目标函数与约束函数,运用MATLAB软件优化工具箱得到最优设计参数,从而实现丝锥自动设计。

Taps are mainly machining tools for internal threads,and its manual design is time-consuming,labor-intensive and error-prone.In order to improve tap design efficiency,reduce labor intensity and save corporate costs,a computer-aided design method to integrate the design of standard taps with checkable parameters and special taps with non-checkable parameters are applied.Taking the minimum cutting torque as the object in tap design,and through the establishment of objective function and the constraint function,the optimal design parameters are obtained by using the MATLAB software optimization toolbox,therefore achieving the goal of automatic tap design.
