which one of the following is used in laser machining

No cutting forces are involved in ECM process 3. What is the full form of LASER in advanced machining processes? Need for Unconventional Processes New materials having high strength and hardness, such as nimonic alloys and alloys with alloying elements such as tungsten, molybdenum, and columbium are difficult to machine by the traditional methods. Laser cutters use a thin, focused laser beam to pierce and cut through materials to cut out patterns and g… Very small space is required to set up ECM process 4. Liquid laser . 7) Which of the following statements are true for Electro-Chemical Machining (ECM)? A liquid laser is a laser that uses the liquid as laser medium. ECM is capable of machining metals and alloys irrespective of their strength and hardness 2. By conventional machining the MRR reduces with an increase in the work … 10 Which one of the following processes would be appropriate for cutting a hole of 0.003 inch diameter through a plate of aluminum that is 1/16 in thick: (a) abrasive jet machining, (b) chemical milling, (c) EDM, (d) laser beam machining, (e) oxyfuel cutting, (f) water jet cutting, and (g) wire by:Eworld Machine 2021-01-01. ECM process consumes very high power 4. Electro-Chemical Machining (ECM) has the highest metal removal rate of about 200-300 mm 3 /s 3. 1. There are many types of lasers including gas lasers, fiber lasers, solid state lasers, dye … 5. GRINDING Multiple choice Questions :-1. The light waves from laser contain only one wavelength or color so it is known as monochromatic light. Which of the following processes use mechanical energy as the principle energy source (3 answers): (a) electrochemical grinding, (b) laser beam machining, (c) conventional milling, (d) ultrasonic machining, (e) water jet cutting, and (f) wire EDM Explain the different types of lasing medium. Laser Beam Machining (LBM) has the lowest metal removal rate of about 0.001-0.002 mm 3 /s. Ch 12 unconventional machining 1. In general, when the material temperature exceeds 90 °C, it will have an adverse effect on laser cutting (easy to blast and over-melt). The classification of the laser cutting machine control system. Grinding is best suited to the machining of 2. 4. The type of gas used to construct the laser medium can determine the lasers wavelength or efficiency. Laser cutting has the phenomenon of heat absorption and thermal diffusion, and the material temperature has a non-negligible influence on the quality of laser cutting. Laser cutting is a technology that uses a laser to cut materials and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses and hobbyists. NTMM By S K Mondal 2. Explanation: Laser beam machining is more versatile and can be used for metal as well as non metal. Chemical Machining (CHM) has metal removal rate of about 0.15-30 mm 3 /s. Laser Cutting Basics: A laser cutter is a prototyping and manufacturing tool used primarily by engineers, designers, and artists to cut and etch into flat material. A laser is a device that emits a beam of coherent light through an optical amplification process. Laser cutting works by directing the output of a high-power laser, by computer at the material to be cut. In laser beam machining process heat affected zone have smaller area in comparison with other unconventional machining processes. Ultrasonic Machining (USM) has metal removal rate of about 5-10 mm 3 /s. Ans. Many materials can be used as the heart of the laser. Following is an abrasive cutting (A) Milling (B) Grinding (C) Laser beam machining (D) All of the above. 2. : Ruby which is a chromium alumina alloy having a wavelength of The full form of LASER is Light Amplification by Simulated Emission of Radiation.
