4. Introduction and Abrasive Jet Machining; Ultrasonic Machining (USM) The mixture of water and abrasive particles passes through a special ceramic mixing tube and the resulting abrasive/water slurry exits the nozzle as a coherent cutting stream of abrasive particles traveling at very high speed. 3. Here is a schematic diagram of abrasive jet Machining process. At the end of this article, you will get a link to download an Abrasive Jet Machining PDF copy of this article for your future reference. We assume that you are OK with this if you are browsing through this website.

The other mechanical machining method is Abrasive jet Machining. This abrasive and gas mixture emerges from a small nozzle at high velocity. After the mixing chamber, the gas and the abrasive mixture goes through the connecting hose to reach to the nozzle inlet.eval(ez_write_tag([[300,250],'riansclub_com-leader-4','ezslot_14',151,'0','0'])); The nozzle is the part that sprays the abrasive mixture on the workpiece surface. The Abrasive Jet machining can be employed for machining super alloys and refractory from materials. It is also used in cutting slot, thin sections, countering, drilling, for producing integrate shapes in hard and brittle materials. 8 (a) shows the schematic diagram of abrasive Water Jet Machining. Abrasive Jet Micro Machining (AJMM) is a relatively new approach to the fabrication of micro structures. Read more about this portal or Sachin Thorat click on below button! 7. Working Principle of Abrasive Jet Machining: The figure shown is the above Abrasive jet Machining. Meaning of Abrasive Jet Machining (AJM): In this process a focused steam of abrasive particles (of size 10 to 40 microns) carried by high pressure gas or air at a velocity of about 200 to 400 m/sec is made to impinge on the work surface through a nozzle, and the work material is removed by erosion by the high velocity abrasive particles. Since oil is a liquid it has the tendency to 'leak' through every gas/slot it finds during movement. Schematic diagram … Abrasive feeder 3. Producing different shapes in parts where traditional machines can not reach. Work material 7. Save my name, email, and website in this browser for the next time I comment. link to Hydraulic seals - Definition, Types, Diagram , Function, Failure, Application, link to Slotter Machine - Types, Parts, Operations, Diagram, Specification. A typical material removal rate for abrasive jet machining is 16 mm/min in cutting glass. Fig. The velocity of the jet is usually 1000km/hour. Hand operation is sometimes adequate to remove surface contamination or in cutting where accuracy is not very critical. Close to 16 years of experience in the field of consumer electronics and appliances domain as a Sr. Design Engineer and Team Leader in India and the United States. Today we will learn about abrasive jet machining principle, working, equipment’s, application, advantages and disadvantages with its diagram. The material removal process is mainly by erosion. It has the ability to cut almost any material while maintaining high precision. a high speed stream of abrasive particles carried in gas medium from a nozzle. The variables that influence the rate of metal removal and accuracy of machining in this process is: 1. Often, deburring is not necessary after a piece has been machined by an abrasive jet. Thanks. As you can see there is a mixing chamber where the high-speed air or gas mixes with abrasive particles. Material removal rate is low and hence its application is limited. Air compressor. of the aim, abrasive jet machining (AJM) is useful just for hard and brittle materials. eval(ez_write_tag([[250,250],'riansclub_com-large-mobile-banner-1','ezslot_0',154,'0','0'])); The feed rate of abrasive can be controlled by the aplitude of vibration of mixing chamber. The machining principle of abrasive water jet was expounded in Q. Liu et al. Abrasive Jet Machining is useful for delicate finishing operations.

Embedding of the abrasive in the work piece surface may occur while machining softer material. What is the fundamental principle of abrasive jet machining? ABRASIVE JET MACHINING AND STUDY OF PROCESS PARAMETERS. If you still have any question for have any queries then please do write in the comment section and I will be happy to respond. Pressure Regulator. Lecture 1-2_Introduction and Abrasive Jet Machining.pptx - Introduction to Modern Machining Processes and Abrasive Jet Machining Offered by Prof Dr ... Block diagram Abrasive Jet Machining AJM Gas Water Suppl y Pressur e regulat; No School; AA 1 - Fall 2019. It is a non-traditional machining process where there is no physical contact between tool and work-piece. A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using an extremely high-pressure jet of water, or a mixture of water and an abrasive substance. Low capital cost 2. As we all know that the pressure and velocity of the gas plays a big role in the machining process, so regulator control that flows rate. That’s all I have in this article. An abrasive is small, hard particle having sharp edges and an irregular shape . Flow rate of abrasive 6. What is abrasive jet machining ? It is often used for cleaning and, polishing of plastics nylon and Teflon components. cool because the carrier gas serves as a coolant. 1. Then the abrasive water jet is passed through the focussing tube for creating square pin textures on the surface of brass sheet as shown in Fig. The abrasive material may accumulate at nozzle and fail the process if moisture is present in the air. As no heat is generated in the process, no change in micro-structure. Wear, misalignment, and damage to the nozzle. As no heat is generated in the process, no change in micro-structure. Abstract:- Abrasive Jet Machine is the device used to remove material by means of high velocity carrier gas and Abrasive mixture. Nozzle needs to change very often as those wears quickly. Air filter. Carrier gas 2. The nozzle is mounted on a fixture. 3. The setup consists of a mixing tube in which high pressurized water is mixed with the abrasive particles. 2. AJMM is a promising technique to three-dimensional machining of glass and silicon in order to realize economically viable micro-electro-mechanical systems (MEMS) It employs a mixture of a fluid (air or gas) with abrasive particles. Commonly used Abrasives are aluminum oxide, silicon carbide, or glass beads. Every gas/slot it finds during movement its application is limited have 3 axes travel able.
