Abstract- Wide application of Abrasive Jet Machine (AJM) is found in machining hard and brittle materials. Machining of brittle materials by AJM is due to brittle fracture and removal of micro chips from the work piece. Embedment of the abrasive particles in the brittle materials results in decrease of machining efficiency. In this paper
Most abrasive jet machines are bench-mounted. They are mounted on a bench where the compressor is able to mix the gas with the abrasive particles. The workpiece is then positioned in front of the machine. To remove material from the workpiece, the machine is activated with the nozzle positioned in the desired area. ...
Abrasive particles are introduced into the mixing chamber from a hopper via a vibratory feeder. The compressed air is dried and filtered before entering the mixing chamber to carry the abrasive particles. The air-abrasive mixture exits the chamber through the nozzle as a high-velocity jet. The nozzle is mounted on a fixture
Abrasive Jet Machining is a material removal process with the help of concentrated abrasive grains enclosed in a nozzle that removes by the action of impact erosion. In abrasive-jet machining, a high-velocity jet containing abrasive particles is aimed at the workpiece surface under …

In Abrasive Jet Machining (AJM), abrasive particles are made to impinge on the work material at a high velocity. The jet of abrasive particles is carried by carrier gas or air. High velocity stream of abrasive is generated by converting the pressure energy of the carrier gas or air to its kinetic energy and hence high velocity jet.
