摘要
关于早期工艺设计理论方法的研究都是以特征信息为基础,不能利用早期阶段粗粒度、非完备的产品信息.为此,采用关键特性表示粗粒度、非完备的产品信息,提出基于核心工艺框架的工艺设计方法.核心工艺框架是对满足关键特性要求的工艺计划的抽象,可表达产品族或零件族中各种变型的核心工艺内容,根据分支和存在规则快速配置工艺计划.基于核心工艺框架的工艺设计过程包括4个步骤:确定产品族/零件族,检索核心工艺框架,配置核心工艺和工艺路线设计,有效性规则、原理性规则和定制性规则确保工艺设计的准确性.最后通过有翼导弹的弹翼主梁的加工工艺验证了此方法的可行性.
The early stage of product development has a crucial effect on capability, cost and quality of products. Research on theory and approach of early process planning was based on feature information, and could not utilize rough-granularity incomplete product information. Therefore, core process skeleton based process planning approach was proposed on the basis of key characteristics which have been proposed to express rough-granularity incomplete product information. Core process planning is a kind of abstract of process plans which satisfy key characteristics requirement, and it expresses core process of various variation of product/part family. Process plans can be configured rapidly according to embranchment and existence rules. The procedure of process planning on the basis of core process skeleton includes four steps： determining product/ part family, searching core process skeleton, configuring core process and process route planning. Validity rule, principle rule and customized rule were employed to assure veracity of process planning. Finally, machining process of the girder of the wing was used to validate feasibility of this approach.
