Abstract
A computational model for the simulation of a laser-cutting process ha s been developed using finite element method. A transient heat transfe r model is considered that deals with the material-cutting process usi ng 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 p rediction of groove depth with different moving speeds.
