Abrasive Water Jet Machining Process

Main parts of water jet machining.

Abrasive water jet machining process.

The abrasive does the cutting through a mechanical sawing action leaving a smooth precision cut surface. Awj cutting is an intricate procedure that is. 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.

Wjm process is applied for cutting of unidirectional carbon fiber fabrics. It is used to circulate the water from the storage tank during the machining process. Water jet machining process is applied for accurate cutting of contours on fiber reinforced plastic with negligible thermal damage. For cutting hard materials abrasive particles are used in the water jet these abrasive particles erode metal from the contact surface.

In these processes the mechanical energy of water and abrasive phases are used to achieve material removal or machining. This process works on basic principle of water erosion. In the water jet machining process a hydraulic pump is used to pump the water from storage tank for. Water jet and abrasive water jet machining.

Most versatile cutting process water jet cutting uses an ultra high pressure stream of water to carry an abrasive grit. Abrasive water jet machining developed in 1974 to clean metal prior to surface treatment of the metal. Water jet trimming of polycarbonate materials with robotic control of water jet has been performed. The metal is removed due to erosion caused by the abrasive particles impacting the work surface at high speed.

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. Abrasive waterjet machining key stages of adhesively bonded repairs. Overview of hybrid machining processes. The pump delivers water to the.

Metal cutting and forming. Mixing chamber or tube. Abrasive waterjet machining awjm is widely used in. Fine particles 0 025mm are accelerated in a gas stream commonly air at a few times atmospheric pressure.

Waterjet is the most versatile process because it is able to cut almost any type of material. 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. This process works on the basic principle of water erosion.
