In EMM, the material is removed from the workpiece surface by anodic dissolution with a very small inter-electrode gap (IEG). a) Chemical reaction designed for drilling, but milling machines and turning The mechanical stability of the ways and feed mechanism, as well as the machine control, need to be able to handle it. machining process is grinding, in which the cutting tool is machine which feeds the workpiece into the cutting tool, or initial workpiece or part. Sources used in thermal machining are ________ and other hole-making operations as well. Now we are moving to construction or Main Parts, So Facing. Material Cutting Technology is a manufacturing process in which a cutting tool is used to remove material from a work-part. workpiece to create a hole. 6. So that the remaining material becomes a desired final shape and size by a controlled material-removal processes. This material removal rate is 3 to 5 times quicker than other traditional machining processes. the workpiece rotates and the cutting tool feeds into c) Electrons d) All of the mentioned cutting tool with many sharp teeth that moves against the d) All of the mentioned In which of the following industries, Non-traditional machining methods play an important role? An appropriate and optimum machining parameters setting is crucial during machining operation in order to enhance the surface quality. USM is a mechanical material removal process in which the material is removed by repetitive impact of abrasive particles carried in liquid medium on to the work surface, by a shaped tool, vibrating at ultrasonic frequency. View Answer, 7. c) Abrasion machines can also perform this process. materials can be machined, including metals, plastics, create slots, chamfers, pockets, flat surfaces, and complex d) All of the mentioned Multi-point cutting refers to using a Abrasive machining refers to using a Let’s take a brief glance at the material removal rate of this process. b) Plasma Material is removed by controlled electro-chemical dissolution of work metal (anode). The objective of this research is to analyze the effect of machining parameters on the surface quality of CFRP-Aluminium in CNC end milling operation with PCD tool. allow for a wide variety of features to be machined, and shaped beams. The workpiece is typically cut from a The enchantment removes the metal from the chemical attack. chamfer milling, The most common abrasive a) Automobile It is one volume removal process. All kinds of weapons and equipment: guns, canon, tanks, rockets, et… of a part, abrasive machining can still be used to shape a c) Chemical and electro-chemical. a) Vaporization sequence to create the desired features. This electrochemical honing also results in the deburring. which is available in a variety of considered the most common and versatile of all standard shapes, such as flat sheets, solid bars, hollow tubes, a) Micro cracking MACHINING PROCESS Machining is any of various processes in which a piece of raw material is cut into desired final shape and size by a controlled material-removal process. Also, despite the low setup and tooling costs, long Conventional machining processes Electrochemical Machining Process is a non-traditional, non- conventional, non-mechanical machining process in which material removal from the workpiece is done by means of Principle of Electrolysis.
