A comparative Experimental Analysis of Sea sand as an abrasive material using Silicon carbide and mild steel Nozzle in vibrating chamber of Abrasive Jet machining process

A number of investigations carried out in an abrasive jet machining process having a traditional material with traditional nozzle. In some publication are focusing on water jet cutting machining and some are focusing on sand bond grinding , some work are wear behavior of nozzle and some are on performance of material in water jet machining. The present research work give an analysis of performance of sea sand in silicon carbide nozzle and mild steel nozzle (newly used ) and their estimate life of nozzle diameter. In this experiment glass used as work piece. The approximate service life of silicon carbide nozzle is 300-400 hrs as it depend on the abrasive material hardness. The performance of the sand in vibration chamber , silicon carbide nozzle is used with variable and constant parameter. It is also noticed that the width of cut is increased with increasing of feed rate. The taper cutting has found to be more at greater stand of distance and work feed rate. Silicon carbide is hard as compared to mild steel but gives its characteristic. The performance characteristic of MRR (material removal rate),SOD (stand off distance) are similar in nature as used by traditional material in this process.
