COMPUTATIONAL MODEL FOR HIGH-ENERGY LASER-CUTTING PROCESS

A computational model for the simulation of a laser-cutting process has been developed using finite element method. A transient heat transfer model is considered that deals with the material-cutting process using a Gaussian continuous wave laser beam. Numerical experimentation is carried out for mesh refinements and the rate of convergence in terms of groove shape and temperature. Results are also presented for the prediction of groove depth with different moving speeds.
