Modeling Study of Engineering Ceramics WEDM Based on Fuzzy Logic

Abstract

relevance between technological parameter and processing effects in WEDM is extremely complex. In order to solve the difficulty of set up mathematical model for technological parameter and processing effects in engineering ceramics WEDM, an prediction model based on fuzzy logic is proposed through establish fuzzy controller by input/output fuzzification, fuzzy inference and settle fuzzy, whereas, build prediction model of engineering ceramics WEDM surface roughness change according to technological parameter utilizing established fuzzy logic controller in matlab. Laboratory finding shows, utilization of this model can precisely predict surface roughness under preset condition with relatively minus error, which further validate the reliability of this model.
