Abrasive jet is a unique micro-machining technique. Particularly for the purpose of surface texturing, it offers the advantages of broad scalability, high efficiency, and minimal side effects. However, the embedding of hard abrasives into the machined surface, especially for soft materials, causing residue contamination, poses a sig nificant challenge. A novel self-generating abrasive jet machining (SGAJM) is proposed in this study. In this method, compressed air is accelerated through a nozzle, generating a pressure drop and low temperatures. This draws in a saturated salt solution, causing crystalline abrasives to precipitate. Consequently, a multiphase jet is formed, enabling the machining of surface textures while effectively resolving the issue of residual hard abrasives.
