摘要： 针对电火花加工工艺的特点，采用专家系统与人工神经网络相给合实现电火花加工智能化CAPP系统——I-EDM-CAPP系统。建立了基于规则的简易Petri网SPN模型以实现加工方法的智能选取；采用复合神经网络（CNN）实现电参数学习模型，从而能够准确地选择并合理地扩展电加工工艺参数。

关键词: CAPP, Petri网, 电火花加工, 复合神经网络

Abstract: An intelligent CAPP system is implemented to solve the complex problem of EDM techniques. An expert system and an artificial neural network are combined to realize an EDM CAPP system. Rules-based simply Petri Net(SPN) is set up for intelligent selection of machining type, and compound neural networks(CNN) is applied to select and expend exactly the electrical parameters respectively.

Key words: CAPP, Compound neural networks, EDM, Petri net
