Optimization of machining parameters for minimal temperature in cylindrical grinding of Al7075/RHA composite

This research work deals with an investigational study on the temperature developed while cylindrical grinding of Al7075/RHA composite. The Al7075 base material is reinforced with rice husk ash (RHA) particles through squeeze casting methodology wherein the amount of RHA in Al7075 matrix is varied as 5, 10 and 15% in weight. The parameters that are taken into consideration for grinding study are RHA %, table feed and depth of cut each at three levels. The experiment is designed based on Taguchi design of experiments and the output response is temperature. The results revels that the RHA %, table feed and depth of cut have inverse effect over temperature. Analysis of Variance (ANOVA) results confirmed that the grinding temperature has greatly affected by the amount of reinforcement present in the matrix. The developed regression equation has the higher ability to forecast the output with minimal deviation.
