Abstract
A computational model for the simulation of a laser-cutting process ha s been developed using a boundary element method. A steady heat transf er model is considered that deals with the material-cutting process us ing a Gaussian continuous wave laser beam. The geometric nonlinearity due to the melting region is handled by an iterative scheme. Numerical analyses are carried out for mesh refinements and the rare of converg ence in terms of groove shape and temperature. Boundary element method (BEM) results ale compared with finite element method (FEM) results.
