During the last years material requirements became more and more specific. Today, the market offers various types of materials and combinations. Even composite materials take on greater significance. Existing processing technologies are faced with the demand of improved productivity accompanied by a higher part quality. Laser beam cutting becomes increasingly more important as a standard cutting process. One special technology, which can handle different types of materials very well, is the laser remote-cutting technology. Disclaiming any cutting gas a nozzle is no longer necessary. In combination with a handling system and a 2D-Scanner the laser beam is flexible in the working area of the cutting system. An assist gas to remove the molten material from the cutting kerf is no longer required. The materials can be cut with high processing speeds economically. This paper describes the processing of various materials, e.g. composite materials, with various laser beam sources in order to reach high quality cutting edges without neglecting the cutting speed. Moreover, the process itself and the advantages will be explained.
