Abstract

This article presents the design of fuzzy logic based model to simulate the material removal rate in ultrasonic drilling of porcelain ceramic. The main objective of the model is its practical application, such that a machine operator can refer to it from time to time, and practicing engineers can use it in process planning. The model is based on two input signals: depth of penetration and time for penetration. The Adaptive Neuro-Fuzzy Inference System (ANFIS) technique of fuzzy based systems for modeling and simulation of the complex systems has been employed. The performance of the model is validated by comparing the predicted results with the actual practical results obtained by conducting the confirmation experiments. The application of χ2-test shows that the values of material removal rate predicted by fuzzy model are well in agreement with the experimental values at 0.1% level of significance.
