PERPENDICULARITY DEVIATION AND SURFACE ROUGHNESS IN ABRASIVE WATER JET CUTTING OF CARBON STEEL

Abstract

Abrasive water jet is cutting tool capable to cut a wide range of materials. Investigation on perpendicularity deviation and surface roughness in abrasive water jet cutting of carbon steel is proposed in this paper. Full factorial design of experiment with three factors, abrasive flow rate, traverse rate and standoff distance, each in two levels is employed to investigate perpendicularity deviation and surface roughness. The analysis of means and analysis of variance are employed to determine effect of factors on perpendicularity deviation and surface roughness. Regression analysis was used to find correlation of perpendicularity deviation and surface roughness versus process factors.
