The highly focused high density energy melts and evaporates portions of the workpiece in a controlled manner.

Laser beam machining sciencedirect. During laser beam cutting the material is locally heated by transferring the energy of the laser beam to the interacting zone. Vs kovalenko t matsunawa a ostendorf r poprawe w schulzlaser machining by short and ultrashort pulses state of the art and new opportunities in the age of the photons. Using the cutting gas flow from the gas nozzle the material is disposed of as vapor melting charge or slag either directly or after a reaction with the cutting gas. Cirp 51 2 2002. The authors propose to develop the modeling and simulation of laser beam machining by using hybrid intelligent approach such as adaptive neuro fuzzy inference system anfis and research is ongoing. For welding ceramics and dissimilar materials like steel and. Shaping of the diode laser beam by optical integrators is the challenge. Laser beam machining lbm state of the art and new opportunities. Sciencedirect is a. Since anfis integrates principles of neural networks and fuzzy expert it can capture the advantage of both the methods in one model. Laser beam machining lbm is one of the most widely used thermal energy based non contact type advance machining process which can be applied for almost whole range of materials. Laser beam cutting is superior to any cutting method conventional or non conventional because of material versatility no wear or change of tool high material utilization and production flexibility and high accuracy and edge quality. 22 laser beam cutting. Beam cutting speed depends on material and thickness both pulsed and continuous laser is used thickness ranges from 05 1 inch used for cutting complex geometry and for clean cutting operation source. Laser beam machining lbm is a thermal energy based advanced machining process in which the material is removed by i melting ii vaporization and iii chemical degradation chemical bonds are broken which causes the materials to degrade.

Laser beam is focussed for melting and vaporizing the unwanted material from the parent material. Effect of laser beam on material 6 source. Laser beam machining used light energy from a laser to remove material by vaporization and ablation energy is concentrated optically laser emits either continuous or pulsed light beam 5 source. The chapter covers areas in laser cutting welding drilling surface engineering additive manufacturing micronano fabrication beam material interactions and systems and optics. It is widely used in cutting sheet and drilling holes. Schematic of laser beam cutting is shown in fig.
