Özet

This paper describes the experimental study of kerf characteristics of Kevlar 49 epoxy composite machined by abrasive water jet. Influence of three process parameters, namely stand-off distance, traverse speed, and water pressure on kerf taper was investigated. Using response surface methodology, experiments were planned, conducted and then the significance of process parameters on kerf taper is studied using analysis of variance (ANOVA). It is found that the traverse rate and water pressure are significant factors followed by stand-off distance. Further, optimization of significant process parameters is performed to minimize kerf taper of the machined sample. A regression model is also developed to for prediction of kerf taper. The model predictions are found in good agreement with experimental results.
