A Research Review on Advanced Approches in Abrasive Jet Machining

Abstract

In the advanced areas of space, missile and nuclear technologies, there arise a need for machining components to maintain exact sharp edges, high accuracy, and precisely sized components. In the present era of modern machining, these requirements can be achieved with the help of advanced machining process like Abrasive Jet Machining (AJM).This paper presents an extensive review of the current state of research and development on abrasive jet machining process.

Multi-Nozzle Abrasive Water Jet for Oil and Gas Platforms Decommissioning: A Review

“…Abrasive water jet (AWJ) is a processing method that has been used and widely adopted in the industry for cutting ductile materials such as aluminum, steel, alloys as well as brittle materials such as stone, concrete and ceramic [4,5]. The AWJ machining techniques are also used in a variety of applications namely for milling, polishing, drilling, and turning [6].…”

“…The AWJ machining techniques are also used in a variety of applications namely for milling, polishing, drilling, and turning [6]. Abrasive jet machining is a nontraditional machine process that operates without producing shocks or heat [4,7]. In AWJ the cutting process takes place based on the erosion of the workpiece material caused by the impact of hard particles [6,8].…”

“…Although the review of the literature shows that, parameters affecting AWJ have been investigated by many researchers, wide experimental investigations are required to fully understand the relationship between the important parameters [4,22]. In the following sections, the important components of AWJ that need further investigations are discussed.…”

“…The process can be easily controlled by varying the parameters such as velocity, flow rate, pressure, standoff distance, grit size, and nozzle angle. Response variables like surface finish, material removal rate, kerfs width is producing a cylindrical hole [4]. The characteristics of the cut depend on the velocity, angle of attack, size and shape, and loading ratio of the abrasive particles [7].…”

“…Nozzles have either rectangular or circular shapes and can be straight to the target at an angle of 180°, or a right angle of 90°. As the wear down of an abrasive nozzle increase during the process, the divergence of the jet stream increases resulting in a high degree of inaccuracy [4,14]. For decom application, the quick wearing of the nozzle is a challenging technical problem that needs to be addressed by researchers to achieve a cost-effective cutting system for offshore application.…”
