Abrasive Water Jet Machining Process

In the water jet machining process a hydraulic pump is used to pump the water from storage tank for.

Abrasive water jet machining process.

Abrasive water jet machining material rate equation and calculator. Metal cutting and forming. It is used to circulate the water from the storage tank during the machining process. The metal is removed due to erosion caused by the abrasive particles impacting the work surface at high speed.

This process works on the basic principle of water erosion. Water jet machining process is applied for accurate cutting of contours on fiber reinforced plastic with negligible thermal damage. In these processes the mechanical energy of water and abrasive phases are used to achieve material removal or machining. The fundamental principle of abrasive jet machining involves the use of a high speed stream of abrasive particles carried by a high pressure gas or air on the work surface through a nozzle.

The abrasive does the cutting through a mechanical sawing action leaving a smooth precision cut surface. Most versatile cutting process water jet cutting uses an ultra high pressure stream of water to carry an abrasive grit. Fine particles 0 025mm are accelerated in a gas stream commonly air at a few times atmospheric pressure. Mixing chamber or tube.

Main parts of water jet machining. Water jet and abrasive water jet machining. In this process a high speed well concentrated water jet is used to cut the metal it uses the kinetic energy of water particle to erode metal at the contact surface the jet speed is almost 600 m s. In this process a high speed well concentrated.

It does not generate any environmental hazards. Wjm process is applied for cutting of unidirectional carbon fiber fabrics. Abrasive waterjet machining key stages of adhesively bonded repairs. Abrasive water jet machining developed in 1974 to clean metal prior to surface treatment of the metal.

Overview of hybrid machining processes. Water jet trimming of polycarbonate materials with robotic control of water jet has been performed. The particles are directed towards the focus of machining less than 1mm from the tip. Abrasive water jet machining awjm is non traditional or non conventional machining process.

Abrasive waterjet machining awjm is widely used in. The pump delivers water to the. Waterjet is the most versatile process because it is able to cut almost any type of material.
