Abstract
A ceramic material is a brittle hard heat resistance and corrosion resistance material it is a made by non material such as clay in this research work alumina as a base material and zerconia as a reinforcement material, alumina reinforced with zerconia matrix composites made by powder metallurgy sintering method with different weight percentage of reinforcement such as 5%, 10% and 15% respectively. Nontraditional machines are used to machining the brittle material because to improve dimensional accuracy of the cutting portion in this work micro abrasive air jet drilling machine is used to remove the unwanted material on the work piece (ceramic composites) in this case 30 µm size of non uniform shaped silicon carbide (SiC) as a abrasive, this present work to optimize the machining parameters on the MRR and kerf by using Taguchi technique, consider input parameters are pressure, abrasive flow rate, standoff distance and nozzle diameter. To conducted experiment on micro abrasive air jet drilling machine (MAADM) as per L27 Orthogonal array (OA) with four input parameters three levels and to analyze the process parameters impact on MRR and kerf and determine the percentage contribution of each parameter on response by ANOVA (General Linear Model) to check the predicted values at 99% confidence level.
