which one of the following is used in laser machining

The type of gas used to construct the laser medium can determine the lasers wavelength or efficiency. Many materials can be used as the heart of the laser. 4. Ans. No cutting forces are involved in ECM process 3. by:Eworld Machine 2021-01-01. 2. Liquid laser . 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. Laser cutting works by directing the output of a high-power laser, by computer at the material to be cut. NTMM By S K Mondal 2. 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 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. 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 Explain the different types of lasing medium. 7) Which of the following statements are true for Electro-Chemical Machining (ECM)? Very small space is required to set up ECM process Laser Beam Machining (LBM) has the lowest metal removal rate of about 0.001-0.002 mm 3 /s. 2. 5. What is the full form of LASER in advanced machining processes? Following is an abrasive cutting (A) Milling (B) Grinding (C) Laser beam machining (D) All of the above. In general, when the material temperature exceeds 90 °C, it will have an adverse effect on laser cutting (easy to blast and over-melt). Electro-Chemical Machining (ECM) has the highest metal removal rate of about 200-300 mm 3 /s 3. ECM is capable of machining metals and alloys irrespective of their strength and hardness 2. ECM process consumes very high power 4. : Ruby which is a chromium alumina alloy having a wavelength of The full form of LASER is Light Amplification by Simulated Emission of Radiation. 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 A liquid laser is a laser that uses the liquid as laser medium. Ch 12 unconventional machining 1. The classification of the laser cutting machine control system. Laser cutters use a thin, focused laser beam to pierce and cut through materials to cut out patterns and g… 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. 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. GRINDING Multiple choice Questions :-1. 1. A laser is a device that emits a beam of coherent light through an optical amplification process. 4. Grinding is best suited to the machining of Chemical Machining (CHM) has metal removal rate of about 0.15-30 mm 3 /s.
