Abstract

This chapter is focused on machining performance of AWJM process during the machining of zirconia (ZrO2) ceramic composites. Experiments are conducted using the Taguchi (L27) method to analyze the influence of AWJM parameters [standoff distance (A), the working pressure (B), and nozzle speed (C)] on the response parameters such as MRR and surface roughness (SR). In addition, regression and ANOVA analysis are performed to show the statistical significance of the AWJM (green machining) process. Moreover, empirical equations are derived which define the responses as a mathematical function of input variables for optimum prediction response parameters for the green machining (AWJM) process. In addition, multiple objective particle swarm optimization based on crowding distance (MOPSO-COD) method is employed to solve the optimization problem that simultaneously minimizes SR by maximizing MRR. The overall optimal setting obtained is A (1.5 mm, level 1), B (150 MPa, level 1), and C (225 mm/min, level 1). The corresponding green attributes obtained are MRR as 345.72 mm3/min and SR as 0.194 µm. Confirmatory results for MRR and SR are found closer to the experimental results and well within the considerable ranges and satisfactory.
