The following work aims to model and simulate laser and plasma cutting of some steel and polymer materials. These types of machining are increasingly used to obtain complex, costly and difficult contours to obtain with current conventional technologies. The Comsol Multiphysics program was used to model with finite elements and to simulate the laser and plasma cutting process of the established materials. After the introduction of the parameters in Comsol Multiphysics and their optimization, experiments were carried out to obtain an optimal cut and some practical tests on the machines specific to each type of materials: stainless steel, steel C45, PVC and plexiglas. These samples were analyzed in terms of cutting quality and implicitly the roughness obtained
