模具高速铣削参数专家系统的设计

Design of High Speed Milling Expert System of Die

针对模具高速铣削生产过程中切削参数设置不合理、劳动效率低下的问题，提出利用模具高速铣削参数专家系统来辅助决策以确定最优工艺方案。首先根据需求分析设计了整个系统的体系结构，以数据库设计理论为基础设计信息库与知识库中各实体间的关系模型并以C# SQL Server为工具来实现，用确定性推论与不确定性推论相结合的方式构建了知识推论机制。最终实现了模具高速铣削参数自动决策的功能。

In order to overcome the weakness of Irrational cutting parameter setting of the production process of the die and inefficient work, a high speed milling expert system of die parts was presented to Cause the optimum craft scheme to be fixed. Firstly, according to the demand analysis to design the system structure, based on design theory of the database, the relation model was designed by C# and SQL Server,The mechanism of knowledge reasoning was constructed by method that the determinacy inference combines with uncertain inference. Finally, The function of the automatic decision of the milling parameter was realized.
