ABSTRACT Ultrahigh-pressure abrasive-water jets (AWJs) are being developed as net shape and near-net-shape machining tools for hard-to-machine materials. These tools offer significant advantages over existing techniques, including technical, economical, environmental, and safety concerns. Predicting the cutting results, however, is a difficult task and a major effort in this development process. The predictions of the A WJ cutting model are checked against a large database of cutting results for a wide range of parameters and metal types. Materials are characterized by two properties: the dynamic flow stress, and the threshold particle velocity. This research along these lines decides to sum up what's more, incorporate that previous exploration with that which has come to fruition as the innovation has moved into progressively far reaching mechanical use. Since water-jetting is currently utilized in a few extraordinary and particular zones where there might be no promptly evident traverse of enthusiasm between the undertakings. It has been conceivable to isolate the innovation into summed up however separate zones of utilization. The utilization of water jets under tension has gotten considerably more typical, in on-going years, for an expanding assortment of assignments. Keywords:

INTRODUCTION
Abrasive-water jets (AWJs) are formed by mixing abrasive particles with high-velocity water jets in mixing tubes as shown in Fig. 1. Conceptually, this technique is similar to that used in air-carried (or gascarried) abrasive-jets, which are conventionally used in abrasive-jet machining (AJM). With AWJs, however, larger quantities of abrasives can be accelerated to higher velocities to produce more coherent jets than typically used in AJM. The capabilities and applications of this technology are discussed elsewhere. The AWJ cutting process involves many parameters, including the following:
Water jet pressure Water jet orifice diameter Mixing tube length Mixing tube diameter Abrasive material Abrasive particle size Abrasive flow rate Traverse speed Angle of cutting Material to be cut
An early investigation on useful uses of AWJM gave a far reaching rundown of potential applicant materials that were effectively machined. Instances of modern Utilizations of AWJM are found in machine instruments for AWJM have been broadly evolved in a few organizations throughout the previous two decades. A few machine devices’ structures are found in this www.irjmets.com
