Paper Abstract

An analysis has been carried out of the time characteristics of the laser cutting process resulting from the solution of heat conductivity equation inside the steel sheet on heat sources (laser beam) inside that sheet. It is assumed that laser beam has a Gaussian spatial shape. The heat conductivity equation and boundary conditions have been derived for a 3D sheet which moves with a constant velocity v towards x direction. Results obtained were compared to solutions of quasistationary equation referring to the same problem.
