The threaded holes employed for mechanical joining are vulnerable to fractures. Take a light trial cut at the right hand end of the workpiece for about .250 inch length. 5. ECM is capable of machining metals and alloys irrespective of their strength and hardness 2. Mechanical Joining is a process for joining parts through mechanical methods, which often involve threaded holes. 1. Metal Machining mechanics-Orthogonal cutting. Turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material. Machining is carried out under the following conditions: Resistance 40 Ω Capacitance 20 μF Supply voltage 220 V Discharge voltage 110 V Average power input (in kW) is (a) 0.373 (b) 0.137 (c) 0.218 (d) 0.500 92. The reality is that many different types of prototypes will have to be created in order to test different aspects. See the 5 Types graphic upgraded to the 6 Types graphic in my MD Sept 2018 column . a) USM b) EDM c) LBM d) PAM View Answer. In this process, the Steel parts are heated in an atmosphere of ammonia (NH 3) for a prolonged period and then cooled slowly. Mill Machining, Milling Process, Horizontal & Vertical Milling Machines Definition. Technically, mechanical engineering is the application of the principles and problem-solving techniques of engineering from design to manufacturing to the marketplace for any object. Related With the help of the milling machines one can perform many operations and functions starting from small objects to large ones. Nonferrous powders are produced by mechanical, chemical, and electrochemical methods. During this process, when Ammonia comes in contact with steel is diffuses into nascent hydrogen and nascent nitrogen. Milling is a process performed with a machine in which the cutters rotate to remove the material from the work piece present in the direction of the angle with the tool axis. Which of the following process comes under mechanical machining? The turning process requires a turning machine or lathe, workpiece, fixture, and cutting tool. The heating temperature for nitriding Ranges from 480 degree Celsius to 550 degree Celsius. Tighten the tool post securely to prevent the toolholder from moving during the machining operation. Answer: a Explanation: USM removes material by mechanical erosion. 8. 9 Which of the following processes would be appropriate for cutting a narrow slot, less than 0.015 inch wide, in a 3/8-in-thick sheet of fiber-reinforced plastic (two best answers): (a) abrasive jet machining, (b) chemical milling, (c) EDM, (d) laser beam machining, (e) oxyfuel cutting, (f) water 7. Surface defects that may be occurred during thermal machining are _____ a) Micro cracking b) Heat affected zones c) Striations d) All of the mentioned View Answer The areas of machine tools, metal cutting, computer numerically controlled (CNC), computer-aided manufacturing (CAM), and sensor-assisted machining are quite wide, and each requires the engineering experience to appreciate a manufacturing operation that uses all of them in an integrated fashion. A resistance capacitance relaxation circuit is used in an electrical discharge machining process. Very small space is required to set up ECM process ECM process consumes very high power 4. No cutting forces are involved in ECM process 3. Getting Help Early. Joining parts using screws or nuts and bolts are common examples of mechanical joining. 8. 7) Which of the following statements are true for Electro-Chemical Machining (ECM)? The comminution of solid metals and alloys is carried out by machining, milling (in impact mills, ball mills, vibration mills, stream mills, and edge-runner mills), and using attritors. Measure the workpiece and adjust the tool bit for the proper depth of cut. 6. Find out how 3D printing has become the sixth manufacturing process in my MD Aug 2018 column.
