Abrasive jet machine is the material removal operation where the material is removed or cut by high velocity stream of air, gas or water and abrasive mixture. The abrasive jet machining (AJM) is a process of non-traditional machine which operators on no physical contact between tool and work piece. The abrasive jet machining can be seemly employed for machining super alloys and refractory form material. The process is also very much seemly for cutting, cleaning, grooving, finishing and

... operations of hard and brittle materials such as glass, ceramics and mica. There is no restriction to material to be machined. Thus it cuts conductive as well as non-conductive materials. In this research work, portable abrasive jet machine was developed using 2D drawings and 3D model with the help of software's. The developed 2D drawings and 3D model were further used for fabricating prototype machine model. The fabricated portable abrasive jet machine has produced precise holes on glass material more efficiently. V. CONCLUSION The portable abrasive jet machine was developed and fabricated with the help of drawings and CAD model. This machine has successfully produced holes on glass material which is brittle and hard in nature. The precise holes were produced on glass material efficiently. This machine can be useful for machining of conducting as well as non-conducting materials. The low cost abrasive jet machine can be useful for industrial applications. The material removal rate increases with increase in abrasive flow rate. The Sic abrasives give more material removal rate and perfectly round holes on glass surface. In future with slight modifications, AJM will become important machine tool on shop floor. There is scope for future work are study of nozzle wear, study of characteristic of abrasive particles, dimensional analysis for calculating theoretical metal removal rate.
