Development of abrasive water jet machining

Early waterjet cutting systems were controlled by tuning such as a mechanical protractor and G-code-coded NC system. But the shortcomings of traditional NC machine G-Code-based waterjet cutting already exist, as the accuracy depends on the changing speed of the nozzle as it runs to the arc interpolation positions. round, sudden changes, or complex profiles. Creating motion control systems to incorporate those variables became a major innovation for the top waterjet manufacturers in the early 1990s. People invented the OMAX software and developed the system for precisely positioning the water nozzle and setting the exact speed at every point on the jet’s putting stroke, using conventional PCs as the controller.

Most water jet cutters produce high-pressure water flow to cut the material through the high-pressure pump. There are two types of pumps commonly used to generate this high pressure. Water is then pushed along the high-pressure hose to the sprinkler. In the nozzle, water is concentrated into a thin beam by a small hole. This water jet is pushed out from the nozzle, cutting through the material by spraying it at speeds up to 2736 km / h. Here abrasive particles are fed into the tap through an inlet. The abrasive then mixes with the water in the mixing tube and is expelled at high pressure.
