14. It is especially more indispensable for machining the parts without rotational symmetry. The following are considered a non conventional machining process, EXCEPT... answer choices . Lathe Machining. The machining can be performed on various components in the form of either conventional or unconventional processes. • The machining medium is solid grains suspended in an abrasive slurry in the former,while a fluid is employed in the WJM process. Mechanical Machining • Ultrasonic Machining (USM) and Waterjet Machining (WJM) are typical examples of single action, mechanical non traditional machining processes. The machining can be performed on a lathe machine, milling machine, ultrasonic machining… 1. b) Conventional milling. a different form of energy (other than the excessive forces exercised by a tool, which is in physical contact with the ASSIGNMENT TOPICS WITH MATERIALS UNIT-I 1. 1.In abrasive jet machining, as the distance between the nozzle tip and the work surface increases, the material removal rate ... 17.Abrasive slurry is used in the following type of machining process. Non-Traditional machining is recommended when we need which of the following features? MCQ on Mechanical Energy Based Unconventional Machining Process. Abrasive Water Jet Machining. The most appropriate one to drill a hole of square cross section of 6 mm × 6 mm and 25 mm deep is (a) Abrasive Jet Machining (b) Plasma Arc Machining (c) Laser Beam Machining (d) Electro Discharge Machining 14. A machining process is called non-traditional if its material removal mechanism is basically different than those in the traditional processes, i.e. Need for the development of unconventional machining methods Unconventional manufacturing processes is defined as a group of processes that remove excess material by various techniques involving mechanical, thermal, electrical or chemical energy or combinations of these energies but do not use a sharp cutting tools as it needs to be used … 1. Machining is a processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. Non-Traditional Manufacturing Processes or Unconventional Machining processes Conventional Machining Processes mostly remove material in the form of chips by applying forces on the work material with a wedge shaped cutting tool that is harder than the work material under machining condition. Conventional Machining Processes 2. a) Complex shapes b) High surface quality c) Low-rigidity structures d) All of the mentioned View Answer c) Wire cut EDM. GATE-2014 The following four unconventional machining processes are available in a shop floor. University. 33 times. The most appropriate one to drill a hole of square cross section of 6 mm × 6 mm and 25 mm deep is (A) Abrasive Jet Machining An unconventional machining process (or non-traditional machining process) is a special type of machining process in which there is no direct contact between the tool and the workpiece. a) Ultrasonic machining. [10] b) Is uncoventional machining process an alternate or complement to conventional machining process?Justify. [5] This set of Advanced Machining Processes Multiple Choice Questions & Answers (MCQs) focuses on “Non Traditional Machining”.
