abrasive jet machining pdf

...................................................�� U�" �� The material removal process is mainly caused by brittle fracture by impingement and then by erosion. Abrasive Jet Machining (AJM) is a non-conventional machining process where a high-pressure air stream with small abrasive particles to impinge the work surface through a nozzle. %�� The abrasive particles are held in a suitable holding device, like a tank and fed into the mixing chamber. 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 was introduced to manufacturing ten years ago and has been increasingly used for treating hard-to-machine and multi-layered materials and as an alternative tool for milling, turning, drilling and polishing. Abrasive jet machining is a non-traditional machining process which is mostly used in machining of hardened metals. >> *$( %2%(,-/0/#484.7*./.�� C About this book. We can cut acrylic, however it may chip or crater at the piercing point or edge of part. 2.2. The abrasive jet machining process is used for carving complex shapes on hard and fragile materials. 's study [48], and it was pointed out that the surface quality and size control of three-dimensional parts, such as abrasive water jet machining of holes and shafts, needed to be further improved [48]. They are important because Introduction They can be used on all types of materials ranging from soft metals to hardened steels and hard nonmetallic materials such as ceramics and silicon. Additional cleaning of the work surface is required due to the sticking of abrasive … It is also capable of cutting harder materials like titanium, ceramics, and stainless steel. A CNC milling machine was modified to an AJM, using the C-frame, X-Y table, stepper motor and other parts of the CNC. • Typically, the inlet water is supplied at ultra-high pressure -- between 20,000 psi and 60,000 psi. The objective of this paper is to optimize material removal rate and kerf width simultaneously using AWJM process on INCONEL 718.

Abrasive Jet Machining is a material removal process with the help of concentrated abrasive grains enclosed in a nozzle that removes by the action of impact erosion. This paper discusses the effects View . The abrasive jet is obtained by accelerating fine abrasive particles in highly pressurized gas (carrier gas). V*, Darshan K. A*, Ashitraj.
