When the abrasive jet strikes the surface of the workpiece, several mechanisms contribute to material removal, including impact, abrasion, and erosion. The high-speed particles collide with the material, transferring their kinetic energy and inducing localized stresses. These stresses exceed the material’s yield strength, causing small particles to fracture or be dislodged. The process is predominantly a form of mechanical erosion; hence, factors such as particle size, velocity, and hardness significantly affect the efficiency of material removal.
