摘要：针对在CAD软件中大规模求取模具零件包围盒效率低、准确度不高等问题，提出了基于零件特征的包围盒计算方法，在NX10.0平台上，基于NXOpen二次开发接口，采用C++编程语言开发自动计算工具。通过对含91个零件的实例验证，批量自动处理耗时3.776s，仅为手工计算时间的1%，输出的Excel表格数据清晰、实用，为模具零件制造提供了详细信息。

Abstract: In order to solve the problem of low efficiency and inaccuracy in computing the bounding box of mould parts in large scale by using CAD software, a calculation method
of bounding box based on the features of mould parts was proposed. On the NX 10.0 platform, based on the NX Open secondary development interface, using C++ programming language to develop automatic computing tools. The example of 91 parts showed that the automatic batch processing time was 3.776 s, which was only 1% of the manual calculation time, and the output data of the Excel table was clear and practical. It provided detailed information for the manufacture of mould parts.
