Laser Beam Machining [with PDF Notes]: Definition ...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
The major advantages of laser beam machining include the following: There is direct contact between the tool and the workpiece. Machining of any material including nonmetal is possible. Drilling and cutting of areas not readily accessible are possible. The heat-affected zone is small because of the collimated beam.

What is Laser LASER stands for Light Amplified Stimulated Emission of Radiation Laser is a device which generates or amplifies light Stimulated emission of electromagnetic radiation Coherent, monochromatic, directional and high power laser beam is used 2
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.
Process Capability. Laser beam machining process Laser beam machining process uses highly coherent light source. This beam can be focused by means of a lens on a very small spot in the work piece. The high power radiation of laser gives rise to high temperature on a small area of work piece. This initiates the cutting process in the work material.

Comparatively high ...
Definition. Laser beam machining (LBM) is a nonconventional machining process, which broadly refers to the process of material removal, accomplished through the interactions between the laser and target materials. The processes can include laser drilling, cutting, grooving, writing, scribing, ablation, welding, cladding, milling, and so on.
