Abstract: Abrasive Jet Machining (AJM) is one of the high precision nonconventional mechanical machining processes in which material is removed by the impingement of high velocity stream of air and abrasives on to the work surface. The mechanics of material removal is mechanical erosion. The fractures of workpiece material in the form of small debris get carried away by the air from the cutting zone. This machining is well suited for brittle and ductile materials, where in brittle materials brittle fracture and for ductile materials shear fracture takes place. Most of the researchers are focused on machining of both the materials using developed/commercial setups. Less number of literatures concentrates on modeling concepts. An attempt has been carried out to develop a semi empirical model for material removal rate (MRR) on brittle material with AJM using dimensional technique. This is carried out by incorporating the various process parameters –pressure (P), stand of distance –SOD (S) and size of the particles (rp). The developed model was then validated with the experimental results.
