Abstract

Lasers are widely used today for the most different kinds of processing operations of most practical materials. Heat treating, surface melting, welding, drilling, cutting and so on can be realized with a quality responding to industrial requirements. Particularly processing problems difficult or impossible to solve by conventional techniques, e.g. with respect to small size, hardness, brittleness, temperature sensitivity, processing of high volume production requiring extensive automatization are calling for the laser. An extensive process control to evaluate and solve practical problems has been developed. The laser parameters, to realize a desired processing of a given material, can be determined in a first approximation and the corresponding laser system can be specified. A first order economico/technical evaluation of the problem solution can be deduced. An experimental optimization considering all the boundary conditions has to be done only if the first evaluation is favourable. This procedure has been applied successfully to many industrial processing problems of variety of materials.
