An Implementation of Fuzzy Logic Technique to Predict the Material Removal Rate in Abrasive Water Jet Machining Process

الملخص

In this study, the material removal rate values, obtained using machining abrasive water jet (AWJM), were modelled using fuzzy logic. The input variables considered are pressure, abrasive flow rate, orifice diameter, focusing tube diameter and standoff distance while the output variable was material removal rate (MRR). Fuzzy logic was developed using  Matlab 2013.The mean absolute percentage errors (MAPE) of the predicted values was employed to compare the results with the previously published results obtained using response surface method technique. . The results showed that the predictive model using fuzzy logic model has reduced the errors by 0.28%, which means, using fuzzy logic model to predict material removal rate is sufficiently accurate.
