Abrasive Jet Machining (AJM) is a non-traditional machining process that utilizes the kinetic energy of a high-speed jet of abrasive particles to erode material from a workpiece. This technique is particularly effective for machining hard and brittle materials, making it highly valuable in industries such as aerospace, automotive, and electronics. Understanding the working principle of AJM involves exploring its setup, operational mechanisms, and the factors that influence its performance.
