Abrasive water jet cutting functions as an advanced, environmentally friendly machining method designed to tackle common manufacturing challenges. These issues include poor material machinability, surface damage, profile cutting constraints, high production costs, and lengthy manufacturing times when making micro- and macro-products. The review outlines the foundational principles and operational problems encountered when cutting various engineering materials. It examines the relationship between input process parameters, erodent abrasive selections, and bulk material properties, evaluating their influence on key performance outcomes such as material removal rates, kerf wall inclination, and overall surface quality. In addition, electron microscopic imagery is utilised to detail the wear mechanisms that occur on diverse materials during cutting. The overall synthesis serves to clarify the operational scope of abrasive water jet machining for researchers.
Producing high-precision engineering parts without causing surface damage or incurring high production costs remains a persistent industrial challenge. Clarifying how abrasive water jet machining parameters dictate cutting efficiency, kerf shape, and material wear helps manufacturers select eco-friendly operational settings that maintain surface integrity while working with demanding materials across both micro and macro scales.
The findings are relevant to manufacturing engineers and industrial fabrication facilities producing micro- and macro-scale components from diverse materials. Because the work compiles baseline principles, parameter influences, and wear mechanisms from existing research rather than testing a dedicated commercial tool, it reflects an early applied research stage requiring further shop-floor parameter optimisation for specific component lines.

Abstract Abrasive water jet (AWJ) cutting is one of the advanced machining techniques to solve the different issues raised in the manufacturing process. Machinability of the material, surface damage, profile cutting, micro-/macro-product making, production time and cost are some of the problems caused. Research on AWJ has addressed the major problems to produce engineering components under the eco-friendly environment. It is a short report on AWJ cutting which is used to explain the basic problems and the principle while machining different engineering materials. In this paper, the influence of input process parameters, erodent/abrasive materials and bulk material properties along response on kerf wall inclination, material removal rate and surface quality are discussed in detail. In addition, the electron microscopic images are used to discuss the wear mechanism on different materials. The information discussed in the paper will support young researchers to understand the AWJ process and its scope.
