项目摘要

In this scientific research, a knowledge based process planning system for, machining and assembly processes of machine products has been studied aimed at the integration and automation of the CIM (Computer Integrated Manufacturing) system. The results are summarized as follows:1. Basic Structure of Production planning System for Machine Products A basic structure of production process planning system for machine products was proposed, which consists of the following subsystems; they are, part exparision subsystem, blank part design subsystem, assembly process planning, machining process planning, forming process planning and inspection process planning.2. Verification of Knowledge Representation Techniques for Production Process Planning It was examined whether or not the knowledge representation methods, such as the production rules, predicate logic, frames and semantic networks, are applicable to representation of the knowledge needed in the production process planning of machine products. It was clarified that these conventional knowledge representation methods can not describe all the knowledge for production process planning.3. Development of Knowledge Based Assembly Process Planning System A knowledge based assembly process planning system has been developed to determine feasible assembly sequences of machine products based on the product model of machine products. This system, firstly, extracts the connecting relations among the parts, and secondly generates feasible sequences of assembly process to connect the parts by applying the knowledge concerning the assembly process.4. Proposal of Analytical Knowledge for Production Process Planning Representation and utilization of analytical knowledge are discussed to realize an advanced production process planning system for machine products.

在这项科学研究中，针对机器产品的加工和装配过程，以知识为基础的工艺规划系统进行了研究，旨在实现CIM（计算机集成制造）系统的集成和自动化。研究结果如下： 1．机械产品生产计划系统的基本结构提出了机械产品生产工艺计划系统的基本结构，该系统由以下子系统组成：分别是零件扩展子系统、毛坯零件设计子系统、装配工艺规划、加工工艺规划、成形工艺规划和检验工艺规划。 2．生产过程规划知识表示技术的验证检验了生产规则、谓词逻辑、框架和语义网络等知识表示方法是否适用于机器产品生产过程规划所需知识的表示。阐明了这些传统的知识表示方法并不能描述生产过程规划的全部知识。 3．基于知识的装配工艺规划系统的开发开发了基于知识的装配工艺规划系统，以根据机器产品的产品模型确定机器产品的可行装配顺序。该系统首先提取零件之间的连接关系，然后利用装配过程的知识生成可行的装配过程序列来连接零件。 4．生产过程规划分析知识的建议讨论了分析知识的表示和利用，以实现先进的机器产品生产过程规划系统。
