摘要:
为了使零件模型已标注的三维尺寸满足标准要求,在不改变设计者标注习惯的前提下,提出了一种基于尺寸差异度的三维尺寸标注自动规范化处理方法.该方法首先根据尺寸标注信息建立尺寸特征,并对各种类型尺寸的可标注几何元素进行了分析;在保证尺寸意义和数值不变的条件下,提出了尺寸关联对象和标注对象的规范化处理规则.然后在计算尺寸差异度的基础上,分别建立了同类尺寸和异类尺寸的规范化处理流程,进而形成了尺寸规范化处理的总体流程.最后应用该方法开发了尺寸规范化处理的原型系统,并以一个板类零件为例进行了实验,对其规范化前后的尺寸信息进行了比较,验证了该方法的有效性.
Abstract:
In order to make the 3D dimensioning of a part model meets the requirements of the national standard, under the premise of unchanging the design habits of designers, an automatic standardized approach for 3D dimensioning based on different degrees of dimensions was presented. First, dimension features were established based on dimensioning information, and geometric elements which can be dimensioned for various types of dimensions were analyzed. Under the condition that the significance and values of dimensions were kept unchanged, the standardized principles and rules for the association object and the dimensioning object of dimensions were proposed. After that, based on computing the different degree between dimensions, the standardized processes for similar type and dissimilar type of dimensions were established, separately, and then the general flow for the standardization of dimensioning was formed. Finally, a prototype system for dimension standardization was developed by using this approach, and an example of a sheet part was used experimentally. The comparison of dimension information before and after standardization was explained, which illustrates the feasibility of the approach.
