The effect of change in design of vibrating chamber for An Experimental analysis for sea sand as an Abrasive material in an Abrasive Jet machining Process for mild steel Nozzle

Abstract

Invention was made to create the needs. Abrasive jet machining is also known as abrasive micro-blasting and it is traditional process. A number of investigations were carried out by imminent personality but no detailed information and design has provided about design of vibration chamber or mixing chamber. This change in shape gives better turbulence to abrasive particles and velocity of abrasive particles. This non sticking characteristic also gives the better effect of erosion of material on work piece and scattering of particle towards objects. The parameter material removal rate, standoff distance, variable pressure used for this experimental study. The work carried out with traditional nozzle like tungsten carbide, silicon carbide which available in market and new proposed mild steel nozzle. Powder flow rate is controlled by the amplitude of mixing chamber. The performance of sea sand in vibrating chamber show by using polynomial where R- square values very near to 1 i.e. 0.9687 using variable parameter.
