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NX Open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3.776 s,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。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.
