non traditional machining can also be called as

Cannot be used for high light reflecting materials. Redressing of the tool is required for deep holes. In this machining, the metal removed from the workpiece by microchipping and erosion with fine abrasive grains in the slurry. From the mixing chamber, the mixture is supplied to the nozzle which is the high strength of a material i.e., tungsten carbide. In this process, the metal removing is the same as that of the EDM process but the method of generation of heat is different. but this is also called non traditional machining. So the newer machining processes developed are often called"Non Traditional machining process " or "Unconventional machining process".In this employs some form of energy like mechanical chemical thermal electro chemical etc.for cutting the material. In this process, high velocity water jet strikes at working surface and metal removed due to erosion by water particle. STUDY. Nontraditional machining can be thought of as operations that do not use shear as their primary source of energy. • The machining medium is solid grains suspended in an abrasive slurry in the former,while a fluid is employed in the WJM process. 3 0 obj 14 Types of Washers & How They Use? Maintain the high degree of dimensional accuracy, so it is recommended for tool and die making. Types of Unconventional Machining Process, Advantages of the unconventional machining process, Disadvantages of the unconventional machining process, Mechanical energy based unconventional machining process, Chemical energy based unconventional machining, Thermo-electric energy based unconventional machining, What is TIG & MIG Welding: Difference Between TIG and MIG welding, What is Welding? 4 0 obj So now, we hope that we have clear all your doubts about Unconventional Machining Process. The gas supply pressure is of the order of 850kPa and jet velocity can be as high as 300 m/s and is controlled by a valve. How it works? In this process the voltage between 50V and 980V and currents from 0.1A to 500A. When the metal is removed by erosion caused by rapidly recurring spark discharges between the … There is no use of force, no direct contact between tool and workpiece. non - traditional machining can also be called as : answer : option c : non - contact machining explanati view the full answer It consists of a mixing chamber in which abrasive particle such as aluminium oxide, silicon carbide, diamond powder, glass particles are used. 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. 1 0 obj Just after the cathode, there is a grid. The laser being coherent or consistent in nature a specific property to generate high power density. The LDM setup consists of a laser tube, a pair of reflectors, one at each end of the tube, a flash tube or lamp, an amplification source, a power supply unit and a cooling system. Extremely hard and brittle materials can be easily machined. Classification of non-traditional machining is based on following factors A high negative bias is applied to this grid so that the electrons generated by this cathode do not diverge and approach the next element. A person who specializes in machining is called a machinist.A room, building, or company where machining is done is called a machine shop.Much of modern-day machining is carried out by computer numerical control (CNC), in which computers are … That’s it thanks for reading. Non-traditional machining is also called advance manufacturing process. 90% of metal is removed by electro chemical action and 10% of metal is removed by the abrasive action of the grinding wheel. Universiti Malaysia Perlis. Abrasive Water Jet Machining Electro Discharge Machining Laser Beam Machining Nontraditional Machining Ultrasonic Machining . An abrasive gun is used to supply an abrasive slurry, which is a mixture of abrasive grains and the water in between tool and workpiece interface under a pressure. If you have any questions about any topic you can ask in the comment section. Cite. Due to the use of very high temperature at the machining zone, there are chances of deformation of the workpiece in case of these sections. PLAY. This whole setup is fitted inside an enclosure, which carries good quality reflecting surface inside. WJM can be used to cut softer materials like plastic, rubber or wood. such as turning, drilling, shaping and milling. The gap between the tool and workpiece is important, thus the downward feed of the tool is controlled by the feed mechanism, which automatically maintains the constant gap. The beam is pulsed so that the released energy results in an impulse against the work surface that does melting and evaporation. In this article, we will discuss what is unconventional machining process and its 9 Types of unconventional machining processes. The unconventional machining is also called as non-traditional machining. LBM uses the light energy of a laser beam to remove material by vaporization and ablation. As particle impact the work surface, they cause small cracks, and the gas stream carries both the abrasive particles and the fractured (wear) particles away. Electrically non-conducting materials cannot be processed by EDM. a different form of energy (other than the excessive forces exercised by a tool, which is in physical It has the ability to cut hard materials such as composites, ceramics, and glass. Further since the machining unit (minimum controllable amount of material that can be removed) in EEM is 0.01 µm or less, it can be called atomic unit material processing.
