| Abstract: | The engineering ceramics has the disadvantages such as high hardness,low ductility and conductivity,so it is difficult to reach the electrical discharge machining(EDM)effect in high efficiency and precision.After analyzing the development of engineering ceramics' EDM,the EDM technology for engineering ceramics based on genetic algorithm(GA) was presented.This technology adopts theories of GA,neural net and fuzzy control to build the multi-loop adaptive control systemit can be used in the wire breakage online preventage,adaptive machining processes and parameters monitoring and controlling,which is a theoretical and technical support for EDM difficult-to-machine material in high efficiency and precision. |
