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.
