Effect of different parameters on surface roughness and material removal rate in abrasive water jet cutting of Nimonic C263

Abrasive water jet cutting is the recent non-conventional and useful processes because of its characteristic advantages. The influence of jet pressure, standoff distance and cutting Speed on surface roughness, material removal rate during abrasive waterjet cutting of Nimonic C263 super alloy has been analyzed in this paper. The roughness of the surface was evaluated in four phases along the width to know the distinct texture of the surface. The rate of material removal was also measured during experiment. The experimental results showed that the roughness of the bottom surface was extremely affected by standoff distance and pressure of jet. The rate of material removal was also noticed to be dependent upon the cutting parameters.
