SURVEY ON RESEARCH DEVELOPMENTS IN ABRASIVE JET MACHINING

Abstract

Abrasive jet machining is a non-traditional machining process which is mostly used in machining of hardened metals. In this machining process a focus stream of abrasive particles are forces to impinge on work piece at high velocity. These high velocity abrasive particles remove metal by brittle fracture or erosion from work piece. This machining process works on the basic principle of abrasive erosion. If a high velocity abrasive particles strike on a hard or brittle work piece, it removes some metal at the striking surface. This metal removal process takes place due to brittle fracture of metal and also due to micro cutting by abrasive particle. This is principle process of abrasive jet machining. This paper presents the application of an elasto-plastic model based explicit finite element analysis(FEA) to model the erosion behaviour in abrasive jet machining(AJM).
