Abrasive Water Jet Machining Diagram

Principle of water jet machine this process works on the basic principle of water erosion.

Abrasive water jet machining diagram.

The filtered gas at a pressure of 2 to 8 kgf cm 2 is supplied to the mixing chamber containing the abrasive powder and. 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. It uses water jet working as a tool to cut the metal. At 300 mpa the water jet can exit the nozzle at mach 2 680 m s and at 400 mpa it can have an exit velocity of over mac 3 1 021 m s.

Extremely powerful abrasive waterjets are capable of cutting through 3 inch 76 mm tool steel at a rate of 2 inches per minute 850 μm s 1 10 inch. Abrasive water jet machining awjm is non traditional or non conventional machining process. Ultrasonic machining usm water jet and abrasive water jet machining. Today we will learn about water jet machining and abrasive water jet machining principle working equipment s application advantages and disadvantages with its diagram.

Abrasive water jet machining developed in 1974 to clean metal prior to surface treatment of the metal. In smithells metals reference book eighth edition 2004. Introduction and abrasive jet machining. In these processes the mechanical energy of water and abrasive phases are used to achieve material removal or machining.

Manufacturers are increasingly turning to waterjet and abrasive waterjet machining in their quest for productivity and quality. Purposes of jigs and fixtures and their design principles. Note that for a water only nozzle that is designed for cutting soft materials the mixing chamber and tube are eliminated and the coherent jet of water alone cuts the material. It consists of a mixing chamber gas filter pressure gauge regulator and the nozzle.

In order for the abrasive waterjet nozzle to cut efficiently and to increase component life it is critical that the jewel orifice is carefully aligned in the nozzle body. 30 8 3 waterjet and abrasive waterjet machining. It is one of the most famous non traditional machining process because it is environment friendly. Today we will learn about abrasive jet machining principle working equipment s application advantages and disadvantages with its diagram.

Design and application of typical jigs and fixtures. In order to cut harder materials like metals or granite an abrasive material is mixed in the water. Fig 1 diagram showing the difference between a pure water and abrasive cutting setup a typical waterjet cutter will operate between 300 mpa 40 000 psi 400 mpa 60 000 psi. The figure shown is the above abrasive jet machining.
