abrasive jet machining working principle

Between tool and work piece, there is a slurry of abrasive. Here the work is to clean the fuel if there are any dust particles present. 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. Both will get a mix that's why this is called a Mixing chamber. With neat sketch describe the principle and equipment for Abrasive Jet machining. These high velocity abrasive particles remove metal by brittle fracture or erosion from work piece. During abrasive jet machining process, material from a surface of workpiece is removed due to impact erosive action of fine-grained abrasive particles impacting at high velocity (200–400 m/s). Abrasive Jet Machining Parts or Construction: Abrasive Jet Machining Working Principle: It provides cool cutting action for glass and ceramics so it can machine delicate and heat-sensitive material. The pressure gauge is used to control the pressure of the compressed used in the abrasive jet machining.as the pressure decides the depth of cutting and amount of force required for cutting. In AJM, air driven abrasive jet strikes the workpiece and removes th view the full answer AJM is used for cutting thin fragile components like germanium, silicon, quartz, mica, etc. In abrasive jet machining, a high-velocity jet containing abrasive particles is targeted at the workpiece under specific conditions. Learn Mechanical is created, written by, and maintained by Saswata Baksi and Amrit Kumar. The abrasive jet process produces surfaces that have high wear resistance. The shape of the abrasives can be regular or irregular. The term abrasive jet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal, stone or glass, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often … It is a non-traditional machining process where there is no physical contact between tool and work-piece. Normally this device work is to check the pressure. As the internal gas pressure increases abrasive mass flow rate increases and thus MRR increases. It is used for engraving registration numbers on toughened glass for car windows. The velocity of carrier gas carries the abrasive particles changes considerably with the change of abrasive particle density. The kinetic energy of the abrasive particles is responsible for the removal of material by erosion process. This is due to the fact that the mass flow rate of the gas decreases with an increase of abrasive flow rate and hence mixing ratio increases so that it will do a decrease in material removal rate because of decreasing available energy for erosion. This stream is directed by means of a suitably designed nozzle on to the work surface to be machined. In this machining process a focus stream of abrasive particles are forces to impinge on work piece at high velocity. Abrasive Jet Machining process - Working Principle: In this AJM system, a focused stream of abrasive grains of Al2O3 or Sic carried by high pressure gas or air at a high velocity is made to impinge on the work surface through a nozzle of 0.3 to 0.5 mm diameter. process takes place due to brittle fracture of metal and also due to micro cutting by abrasive particle this is principle process of abrasive jet machining abrasive jet machining ajm is one of the mechanical energy based modern machining processes where material is removed by controlled micro cutting action caused by the impact of a AJM differs from age old sand blasting technique by the achievable level of accuracy and precision. In abrasive jet machining process, a stream of abrasive particles carried by the high-pressure gas or air is made to effect on the work surface through a nozzle, and the work material is removed by erosion due to the high-velocity abrasive particles. 4.1.2.2 Working Principle, Process Mechanism, and Significant Process Parameters. Nozzle directs abrasive jet in a controlled manner onto work material maintaining the desired nozzle tip distance from the workpiece. 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. For machining hard materials like carbide, ceramic, etc. Copyright © 2020 TheMechanicalEngineering.com. The nozzle is usually made up of tungsten carbide because it is subjected to a high degree of wear. Abrasive Jet machining Consists of Various Parts: A high-velocity jet of airlike nitrogen carbon dioxide etc and enclosed abrasive particles is aimed at the workpiece under controlled conditions. The filtered gas at a pressure of 2 to 8 kgf/cm2 is supplied to the mixing chamber containing the abrasive powder and. The material of the nozzle should be able to withstand corrosion. Abrasive generally used are Aluminium oxide, Silicon carbide or glass powder. In abrasive jet machining, the capital cost is low as it is easy to operate. The gasses used in AJM are CO 2, N 2 or dry air at 2 to 10bar. In this machining, the Abrasive particle size is 10-40 Micros. Note: You can download whole articles PDF at the end of the articles. In this machining process a high speed steam of water jet impinge on the work piece which removes metal from contact surface by erosion.
