AN EXPERIMENTAL STUDY OF KERF PROPERTIES OF LEAD ZIRCONATE TITANATE CERAMIC MACHINED BY ABRASIVE WATER JET MACHINING
Keywords:
Abrasive water jet Machining, lead zirconate titanate ceramics, kerf properties, optimizationAbstract
The present paper describes the experimental study of kerf properties in abrasive water jet machining of lead zirconate titanate ceramic material. Process parameters namely traverse rate, water pressure and stand-off distance are considered in the present study. Design of experiments is performed on the basis of response surface methodology to investigate the influence of process parameters on kerf taper. Further, analysis of variance is performed in order to identify significance and influence of process parameters on kerf taper. It is found that traverse rate and water pressure are most significant parameters followed by stand-off distance. On the basis of experimental analysis, a second order mathematical model is developed to predict kerf taper. Model predictions and experimental results are found in reasonable agreement. Lastly optimization of process parameters is performed to minimize kerf taper.
