Electron beam machining lbm. Electron beam machining is the metal removal process by a high velocity focussed stream of electrons which heats melts and vaporizes the work material at the point of bombardment. Like a beam of high velocity electrons a laser beam is also capable of producing very high power density. Laser beam machining lbm nptelhrd. Lecture series on manufacturing processes ii by profabchattopadhyay prof. Laser beam machining lbm process utilizes a coherent beam of laser photons having same frequency wavelength and phase as the heat source for material removal purpose. Advantages of laser beam machining. The deflecting coils allow the beam to have a range of movement of 12 mm. An optical viewing system is required in order to allow the operator to see the work in order to position the beam. For more details on nptel. Though lbm is not a mass material removal process it is possible to use this process in mass micro machining production. Laser is a highly coherent in space and time beam of electromagnetic radiation with wavelength varying from 01mm to 70mm. Any solid material which can be melted without decomposition can be cut with the laser beam. Search for mechanical guru in facebook hello dosto mera name h ankit ras aur le k aaya hu appk lia mechanical guru ka ek aur latest episode a. 77 uv a laser beam machining lbm in laser beam machining lbm the source of energy is a laser which focuses optical energy on the surface of the workpiece. Laser light amplification by stimulated emission of radiation is basically a coherent and amplified beam of electromagnetic radiation.

In this post you learn what is electron beam machining how its done with its working principle advantages of ebm accuracy and limitation of electron beam machining. The electron beam can be controlled very accurately and machining tolerances of 0005 mm are possible. On this channel you can get education and knowledge for general issues and topics. Like us on fb. Pauldepartment of mechanical engineering iit kharagpur. Other major advantages of the laser beam machining include the following. The highly focused high density energy melts and evaporates portions of the workpiece in a controlled manner.
