Optimization of machining parameters of hard porcelain on a CNC machine by Taguchi-and RSM method

Abstract

In order to build up a relationship between quality and productivity, the present work focuses an optimized approach to  establishing the multi-objective machining  parameters and mathematical models for Pressure and Voltage on CNC turning  machine (SINUMERIK802D). The Pressure and Voltage seem to be known as  quality issues; they are as well presumed to have direct association with productivity. In this study, minimization of response parameters has been identified by using design of  experimental methods, Taguchi Analysis and Response surface methodology (RSM). The conduct of experiments was made by employing the Taguchi’s L27 Orthogonal array to design the experiment by considering spindle speed (SS), feed rate (FR), angle of cut (AOC) and depth of cut (DOC) as Machining parameters. The model for the Pressure and Voltage, as the function of  response parameters, is obtained using the RSM. Finally, the result of developed mathematical model is examined by ANOVA. Experimental results indicate that the feed rate, angle of cut and depth of cut are the leading parameters that affect the Pressure (P). similarly for Voltage (V), all the cutting parameters (Spindle speed, feed rate, angle of cut and depth of cut) are found to be significant, which can be diminished when the significant factors were kept at the lower level, while other factors were kept at the highest level. On the Basis of analysis, it is found that both the optimization techniques predict the results in fair agreement.
