摘　　要：随着企业快速响应市场的需要,参数化技术广泛应用于产品设计研发中。基于三维CAD系统的参数化技术主要考虑的是产品的基本尺寸设计,很少考虑尺寸公差,而尺寸公差又是产品的重要设计指标,所以为了解决尺寸公差参数化设计问题,对零件参数化模型中的尺寸公差信息表达、提取与标注方法进行了研究,提出了一种基于参数化技术的零件尺寸公差设计方法。利用VC++,对三维CAD软件SolidWorks进行二次开发,开发出了基于SolidWorks的零件尺寸与尺寸公差集成参数化设计插件。以轴类零件为例,对提出的方法和开发的插件进行了应用验证。In order to make fast response to market requirement, the technology of parameterization is more and more widely applied to the design and development of product. Currently the technology of parameterization based on 3D CAD systems mainly concerns about design of basic dimension, and seldom about dimensional tolerance. But dimensional tolerance is an important indicator in design. To solve the problem of parameterization in dimensional tolerance, research on the method of dimensional tolerance information in the expression, extraction and labeling for parametric model of parts, a variant design method with dimensional tolerance is presented in this paper. And integrate between variant design method of dimensional tolerance and variant design method of dimension, part variant design method with dimension and dimensional tolerance is synchronization completed. According to secondary develop the parametric CAD software SolidWorks, a part variant design with dimension and dimensional tolerance plug-ins integrated with based on SolidWorks is developed with VC＋＋. As an example, all methods and development of plug-ins are applied to a case study of shaft, and the feasibility is also verified.
