Laser beam machining modeling. In laser machining each pulse has to have. It is used to machine both metallic and non metallic material. Benefits and limitations of various methods in modeling laser beam machining. The heating of the material resulting in melt through the melt ejection and the oxygen reaction in the case of fusion cutting. Co2 and ndyag lasers are. 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. The theory of artificial intelligence methods. Laser beam machining is a thermal machining process which uses laser beam to produce heat. Since anfis integrates principles of neural networks and fuzzy expert it can capture the advantage of both the methods in one model. Review of modeling with analytical numerical and artificial intelligence methods. It is a non conventional machining process in which no tool is used. 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. When modeling the laser machining mechanism mathematical theories of the physical processes are applied to three main issues. A hybrid method for modeling has been proposed for future works.
