This test is Rated positive by 85% students preparing for Mechanical Engineering.This MCQ test is For example, laser drilling and laser cutting are often used interchangeably. LASER BEAM MACHINING(LBM)PROCESS 1. Ruby laser is most efficient when The beam of a single transverse mode (gaussian beam) laser eventually diverges at an angle which varies inversely with the beam diameter, as required by diffraction theory. Ultrasonic Machine and its Process Parameters; Electrical Discharge Machining (EDM) Die-Sinker EDM and its Systems; Wire Cut Electric Discharge Machining (WEDM) Laser Beam Machining (LBM) Equipment of Laser Beam Machining, Process Parameters and Safety Issues; Electrochemical Machining (ECM) The Subsystems of Electro-Chemical Machining LASER stands for Jan 01,2021 - Unconventional Machining Process - 3 | 10 Questions MCQ Test has questions of Mechanical Engineering preparation. It works on the principle that when a high energy laser beam strikes the surface of the workpiece. The heat energy contained by the laser beam gets transferred to the surface of the w/p. This beam can be focused by means of a lens on a very small spot in the work piece. 4, pp. Electron beam machining is same as laser beam machining process in which except laser, high speed electron beam impinges on work piece. All Rights Reserved. c) Drilling c) Laser beam machining process You can control the beam intensity, length and heat output depending on the material you are working with, and can also user a mirror or special lens to further focus the laser beam. - The machining carried out by an intense and unidirectional beam of light provided by laser, is called as Laser Beam Machining (LBM) process. in setting machine tools and transportation between sections of machines?
