Today we will learn about abrasive jet machining principle working equipment s application advantages and disadvantages with its diagram.
Abrasive water jet machining diagram.
It consists of a mixing chamber gas filter pressure gauge regulator and the nozzle.
Design and application of typical jigs and fixtures.
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.
Jigs and fixtures for machine shops.
In smithells metals reference book eighth edition 2004.
In these processes the mechanical energy of water and abrasive phases are used to achieve material removal or machining.
The figure shown is the above abrasive jet machining.
It is one of the most famous non traditional machining process because it is environment friendly.
In order to cut harder materials like metals or granite an abrasive material is mixed in the water.
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.
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.
Ultrasonic machining usm water jet and abrasive water jet machining.
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.
Principle of water jet machine this process works on the basic principle of water erosion.
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.
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.
Abrasive water jet machining awjm is non traditional or non conventional machining process.
The filtered gas at a pressure of 2 to 8 kgf cm 2 is supplied to the mixing chamber containing the abrasive powder and.
Today we will learn about water jet machining and abrasive water jet machining principle working equipment s application advantages and disadvantages with its diagram.
Purposes of jigs and fixtures and their design principles.
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.
Manufacturers are increasingly turning to waterjet and abrasive waterjet machining in their quest for productivity and quality.
Abrasive jet machining is a non traditional machining process which is mostly used in machining of hardened metals.
