一种基于知识库和最优化的加工流程设计方法

本文应用计算机知识库结合最优化方法,建立了一个加工流程设计方法,这一系统可将零件的加工特征转化为的加工操作流程的技术要求,然后通过求解一个约束优化问题,从而寻找在技术上可行（满足技术要求）的、经济上最优（满足一定的经济评价指标）的加工操作流程。

A knowledge-based optimal methodology process planning

In this paper, we construct an optimal methodology in process planning which is combined with the knowledge base. Firstly, an expert system which consisted by two knowledge bases can convert the features of the parts into some operations and some technological constraints. Secondly, an optimal process planning which is a feasible （by some technological constraints） and effective （by some economical standards） process is given by solving an optimization problem. Finally, a hole-machining example is employed to illustrate our methodology.
