Water jet machining invented 1970 a waterjet consists of a pressurized jet of water exiting a small orifice at extreme velocity.
Abrasive water jet machining pdf.
It uses water jet working as a tool to cut the metal.
It is one of the most famous non traditional machining process because it is environment friendly.
Principle of water jet machine this process works on the basic principle of water erosion.
30 8 3 waterjet and abrasive waterjet machining.
Water jet cutting a technology on the rise october 2010 page 7 5.
These high velocity abrasive particles remove metal by brittle fracture or erosion from work piece.
In smithells metals reference book eighth edition 2004.
Two types of cutting let us take a closer look at the basics of the two waterjet cutting methods.
Today we will learn about water jet machining and abrasive water jet machining principle working equipment s application advantages and disadvantages with its diagram.
In order to cut harder materials like metals or granite an abrasive material is mixed in the water.
It is a fast.
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.
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.
Water jet machining uses water mixed with abrasive materials projected with high pressure typically 0 7 mpa and focused on the workpiece.
Manufacturers are increasingly turning to waterjet and abrasive waterjet machining in their quest for productivity and quality.
Abrasive jet machining definition.
In this machining process a focus stream of abrasive particles are forces to impinge on work piece at high velocity.
Abrasive water jet processes.
Abrasive jet machining is a non traditional machining process which is mostly used in machining of hardened metals.
Used to cut soft materials such as foam rubber cloth paper food products etc.
The abrasive jet machining is the process of impinging the high speed stream of abrasive particles by high pressure gas or air on the work surface through a nozzle and metal removal occurs due to erosion caused by high speed abrasive particles.
Pure water cutting pure waterjet is used mainly for relatively soft materials such as plastic textiles paper sealing materials metalic foils plywood.
Powder blasting or abrasive jet machining is a technique in which a particle jet typically al 2 o 3 particles of 3 30 μm is directed toward a target for mechanical material removal.
