| 摘要: |
| 在分析CAPP中各种工艺决策实现方法的基础上，提出了基于关系数据库的工艺决策模型，以这一模型下的工艺生成为主线，进行了工艺知识的分析、组织，基于关系数据模型实现了工艺知识的计算机内部表达。结果表明：这种表达方式能够保证工艺生成过程中零件信息与工艺知识之间的高效匹配，及不同加工环境下工艺知识的维护与更新。 |

| Technical knowledge expression based on relation model |
|
|
| Abstract: |
| This paper offers the technical decision-making model which is based on relation database management,and technical knowledge is analyzed,organized and expressed in computer on the basis of relation data model according to the technical decision-making model.The first reference in the paper shows:the expression could efficiently ensure the matching between technical knowledge and part information when the technical decision-making is processing,the maintenance and renewal of technical knowledge in different manufacture conditions are put forward as well. |
| Key words: CAPP,technical knowledge,expression method |
