摘要：

针对我国叶片精锻模具逆向设计精度低、设计过程复杂等问题，运用VS自定义算法，实现了对模具型面点云数据的分块化处理，提高了数据点处理精度；运用UG二次开发，实现了曲线曲面的参数化建模和模具模型的检测与自动化修正，并运用MenuScript菜单脚本，实现点云数据处理、模具逆向建模以及检测与修正在UG中的集成，提高了模具逆向设计效率；最后运用Deform-3D软件对叶片模具设计的某些参数进行了验证，并通过工程实例对逆向设计的叶片模具进行了检测分析。

For the problems of poor precision on reverse design and complicated design process for blade precision forging die, the block processing of the die surface cloud data was realized by VS custom algorithm, and the precision of data processing was improved. Then, the parametric modeling of curve, surface and the detection and automatic correction of the mold model were realized by the secondary development of software UG, and the efficiency of die reverse design was improved, and the integration of point cloud data processing, die reverse modeling ,detection and correction in UG were realized by MenuScript. Finally, certain parameters of the blade die design were verified by software Deform-3D, and the blade mold of the reverse design was tested and analyzed by engineering examples.
