Abstract

Abrasive jet machining (AJM) is the method in which an abrasive additive and high-water pressure are used to provide a strong cutting force in cutting high hardness materials. Almost all materials in sheet form can be cut using this method. Abrasive particles such as garnet, aluminum oxide, silica sand, silicon carbide, and zirconium are added into high-pressure water in this technique. These abrasive particles facilitate the cutting process easier by increasing the erosion effect of the water. The water jet machining (WJM) method is used to cut soft materials such as foam, rubber, and plastic without abrasive, while AJM can be used to cut harder materials such as titanium, aluminum, stainless steel, glass, and tiles. This method is considered environmentally friendly because it is a process performed without using a coolant. It is preferred for cutting many engineering materials because it is effective for achieving dimensional stability and precise tolerances. Water jet pressure, traverse rate, abrasive mass flow rate, standoff distance, and abrasive grit size independent variable parameters are effective on the outputs of depth of penetration, cutting rate, surface roughness, taper cut ratio, and top kerf width in AJM. These independent variable parameters differ in the processing of each different material and must be controlled in terms of product service life. Current studies in the literature on AJM presented in detail and machinability outputs revealed comparatively in terms of sustainable manufacturing in this chapter.
