Abstract: Abrasive jet machining is a viable option for cutting fragile materials such as single crystals, glasses, and polycrystalline ceramics, as well as performing critical machining to create complex forms and workpiece profiles. This machining method is non-thermal, non-chemical, produces no changes in the work piece's microstructure, chemical, or physical properties, and produces machined surfaces that are nearly stress-free. As a result, it is widely utilized in the machining of hard and brittle materials that are difficult to cut using standard methods. Many process parameters affect the performance of an abrasive jet machine, including abrasive mass flow rate (AMFR), stand of distance (SOD), nozzle diameter, pressure, abrasive particle size, and traverse speed. Many reaction characteristics, such as Material Removal Rate (MRR), surface roughness, depth of cut, radial overcut, and taper angle, can be obtained as a result of all of these process factors. In this work, we look at how those characteristics affect various materials such as Alumina ceramic, Glass fibre, Nickel 233 alloys, Kevlar epoxy composites, porcelain tiles, and soda-lime glass. This research presents a literature review to better understand the impact of several process parameters on different materials, such as abrasive grain size, pressure, and SOD, in order to achieve good quality and precision on an abrasive jet machine.
