Abstract
In this investigation non conventional machine is used to drill a ceramic composite work piece with given input parameters abrasive particles (SiC) are combined with gas in a mixing chamber the size of the abrasive particles is 30 µm and these particles are impinged targeted surface on the work piece with high velocity. An experiment was carried out in accordance with Taguchi's design of experiments in order to determine the signal-to-noise ratio and prediction values of 27 experiments. Four input parameters were used to carry out the experiment on an abrasive air jet drilling machine. We ran one experiment for each orthogonal array combination, and using ANOVA we discovered that the process parameters have a significant influence on kerf. According to the ANOVA, the input parameter standoff distance has the greatest impact on the kerf, followed by air pressure, abrasive flow rate, and finally specimen type. In this work, the investigation brings as per L27 orthogonal array (OA) by varying Pressure, Standoff distance, Abrasive Flow Rate, and percentage of reinforcement into matrix material respectively.
