Unit-IV Electron Beam machining and Laser Beam Machining Theory of EBM • Electron Beam Machining (EBM) is a thermal process. • Here a steam of high speed electrons impinges on the work surface so that the kinetic energy of electrons is transferred to work producing intense heating.
in which a focused laser beam is used to scribe the grooves on the work surface all around the machining zone and then a defocused laser beam is used for heating this zone. The heat induces the tensile stress and the stress concentration increases at the groove tip which results the fracture in the direction of groove cracks.
A laser beam machining is a non-conventional machining method in which the operation is performed by laser light. The laser light has maximum temperature strikes on the workpiece, due to high temp the workpiece gets melts. The process used thermal energy to remove material from a metallic surface. Laser Beam Machining Working Principle:

a) Conventional Machining Processes b) 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.
Here are some limitations of laser beam machining –. High capital and operating cost. High power consumption. Difficult to cut highly conductive and reflective materials like aluminium and copper. The life of the flashlight is short. A skilled operator is required to control the process.

Disadvantages of Laser Beam Machining: High initial cost. This is because it requires many accessories that are important to the machining process by Laser. Laser beam machining requires a highly trained worker to operate the machine. Low production rate because it is not designed for mass production. The machining process requires a lot of energy.
History of Laser Beam Machining. The laser cutting machine is used to drill holes in the diamond dies in the year 1965 and later on, the laser-assisted oxygen jet cutting for metals was started in the year 1967. In the early 1970s, this technology is used to cut titanium for aerospace applications. What is Laser Beam Machining
LBM is nontraditional thermal process. In thermal removing processes, thermal energy, provided by a heat source, melts or vaporizes the volume of the material to be removed. Among thermal removal methods, Electrical discharge machining or EDM is the oldest and most widely used. Electron-beam (EBM) and laser beam machining (LBM) are newer ...

Laser Beam Machining (LBM)Laser-beam machining is a thermal material-removal process that utilizes a high-energy, coherent light beam to melt and vaporize particles on the surface of metallic and non-metallic work pieces. Lasers can be used to cut, drill, weld and mark. LBM is particularly suitable for making accurately placed holes.
A laser beam machining is a non-conventional machining method in which the operation is performed by laser light. The laser light has maximum temperature strikes on the workpiece; due to high temp, the workpiece gets melts. The process used thermal energy to remove material from a metallic surface.
This heat source may be in the form of a laser beam, electron beam, plasma beam, high-frequency induction or electric current etc. Laser-assisted machining is one of the important and most widely used category of the heat-assisted HMPs. Laser-assisted HMPs are of two types: 1. Laser-assisted mechanical machining: in which, a laser is used to ...
