A laser beam machining is a non-conventional machining process in which the operation is performed by the application of laser light which exhibits the maximum temperature strikes onto the workpiece to remove the material from the surface of the workpiece. The Abbreviation of LASER is Light Amplification Stimulated Emission of Radiation.

 · The intensity of the incoming beam is expressed by I0. The decrease of the laser intensity in the depth is given by I x =I 0 e −αx where α the optical absorptivity of the material and x the depth into the material. An important quantity is the penetration depth δ ( δ =2/ α) in which almost all laser energy is absorbed.
