In 1970’s water jet was being started to be used as a source of cutting soft materials such as leather, frozen meat, thin Aluminium sheets etc… Later in the 1980’s abrasives were being added to the water jet to increase the cutting action so that much high strength materials such as steel, cast iron can be machined through the process. This addition of abrasives led to the idea that if abrasives are made to impinge at high velocity on the material then material removal would take place. Thus abrasive jet machining evolved that used a nozzle for impinging the abrasive particles at high velocity on to the work material. Significant amount of research is carried on this process to increase the material removal rate and also on the type and shape of abrasives used for a particular type of material. The advantage of this process is that intricate shapes can be produced by this process but the material removal rate is rather low. The abrasive jet machining setup is shown in the figure below.
The above diagram shows a schematic of abrasive jet machining showing various components of a abrasive jet machining setup.
