WORKING MODEL OF WATER JET CUTTING SYSTEM ON LOW PRESSURE

Abstract

Cutting of raw materials is one of the most common functions in industries. With the advent of globalization and tough competition from multinational companies, it becomes very essential for production houses to reduce/eliminate wastes due to inefficient cutting methods. Every cutting method is based on the input of energy into the material, in order to overcome the chemical bindings present in the structure of the material. Thermal cutting methods, for example, utilize the energy of chemical reactions, electricity, or light to produce high temperatures in order to melt the material at the cutting kerfs. Mechanical methods utilize the kinetic energy of the moving tool or form ductile materials through the application of pressure. However, these methods causes distortion of material in the heat affected zone. In Water-jet Cutting, the energy of the rapidly moving jet is utilized either in the form of a pure water-jet or abrasive water-jet and then applied to the work piece causing micro-erosion. The cutting water works as a cooling agent of cutting edge, thus allowing for a very high quality cut without producing heat affected zone.
