Fuzzy logic based modeling of CO2 laser cutting for stainless steel sheet

CO2 laser cutting is most popular technologies in modern sheet metal processing industries. Thus the technologies have been developed expert system using fuzzy logic model to predict the CO2 laser cutting process parameter on 2.5mm thickness stainless steel sheet. The fuzzy logic model developed in MATLAB using the mamdani techniques. A set of 25 training data used to format of input parameters of laser power, Cutting speed, Gas pressure and focal position and responses are top kerf width, bottom kerf width and kerf deviation. The relationship between fuzzy logic model and experimental value is good correlation. Based on the results the proposed fuzzy model is to predict the top kerf width, bottom kerf width and kerf deviation on stainless steel sheet. © 2006-2017 Asian Research Publishing Network (ARPN).
