摘　　要：针对现有工艺尺寸标注方法存在无法精确描述零件加工前后特征变化的问题,提出面向三维工艺智能设计的工艺尺寸快速标注方法。首先,建立去除体的参数化快速建模方法,构建去除特征与定形尺寸之间的组织与管理机制;其次,在工艺模型逆向创建过程中,分析工序特征、去除体与工艺尺寸三者之间的关联关系,构建“特征-尺寸-去除体”约束机制以快速生成工艺模型的工艺尺寸;然后,根据工艺尺寸标注元素优先级和尺寸间的约束关系,构建工艺尺寸的完备性检查与规范化处理方法;最后,基于三维零件工艺设计系统,集成开发工艺尺寸标注模块,选用两个典型板腔类复杂加工零件工艺设计为对象,验证工艺尺寸快速标注方法的可行性与有效性。Aiming at the problems that the existing technological dimension marking methods could not accurately describe the feature changes of parts before and after machining,a fast technological dimension marking method oriented to 3D technological intelligent design was proposed.Firstly,a parameterized fast modeling method for the removal body was established,and the organization and management mechanism between the removal feature and the dimension was established.Secondly,in the processes of reverse creation of technological model,the relationship among technological characteristics,removal volume and technological dimension was analyzed,and the constraint mechanism of“feature-dimension-removal volume”was established to quickly generate technological dimension of technological model.Then,the completeness check and standardized processing method of technological dimensions were constructed according to the constraint relationship between the priority of process dimensions marking elements and dimensions.Finally,based on the 3D part technological design system,the technological dimension marking module was integrated and developed.Two typical complex mached parts were selected as the objects to verify the feasibility and effectiveness of the rapid technological dimension marking method.
