Abrasive Water Jet Machining Diagram

It is one of the most famous non traditional machining process because it is environment friendly.

Abrasive water jet machining diagram.

Water jet machining wjm also called water jet cutting is a non traditional machining process in which high velocity jet of water is used to remove materials from the surface of the workpiece wjm can be used to cut softer materials like plastic rubber or wood. Principle of water jet machine this process works on the basic principle of water erosion. Jigs and fixtures for machine shops. 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 consists of a mixing chamber gas filter pressure gauge regulator and the nozzle. The figure shown is the above abrasive jet machining. Today we will learn about abrasive jet machining principle working equipment s application advantages and disadvantages with its diagram. 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. Design and application of typical jigs and fixtures. Manufacturers are increasingly turning to waterjet and abrasive waterjet machining in their quest for productivity and quality.

Abrasive water jet machining awjm is non traditional or non conventional machining process. 30 8 3 waterjet and abrasive waterjet machining. Abrasive jet machining is a non traditional machining process which is mostly used in machining of hardened metals. 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.

Purposes of jigs and fixtures and their design principles. 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. It uses water jet working as a tool to cut the metal. The filtered gas at a pressure of 2 to 8 kgf cm 2 is supplied to the mixing chamber containing the abrasive powder and.

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. 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. In these processes the mechanical energy of water and abrasive phases are used to achieve material removal or machining. In smithells metals reference book eighth edition 2004.
