Keywords:
Abrasive water jet machining, lead zirconate titanate, surface roughness, optimizationAbstract
The present paper describes the research work involved in experimental study of abrasive water jet machining (AWJM) of lead zirconate titanate (PZT) ceramic. Influence of three process parameters namely stand-off distance, water pressure and traverse speed on surface roughness of machined samples is studied. Response surface methodology approach is used to plan the design of experiments. Relative significance of process parameters and their influence on surface roughness are identified on the basis of analysis of variance. It is found that water pressure and stand-off distance are most significant parameters followed by traverse speed. Some machined surfaces are observed by using scanning electron microscope. On the basis of experimental analysis, a regression model is developed to predict surface roughness. The model is developed with respect to significant parameters, interaction and quadratic terms. Model predictions are in congruence with experimental results. Optimization of process parameters is also performed on the basis of desirability approach in order to minimize surface roughness.
