At present lasers are used in many fields of the technique. They are useful among others in metrology, incremental methods of manufacturing of the parts made from powders of metals or ceramics, to surfacing by laser welding (building up). Laser beam can replace traditional methods of machining, as far used in the technological processes, but related to decrease of the material and the turnings formation. However preferred in modern industry the cleaner production strategy recommends the replacement old methods and...

The article presents a case study of the laser cutting which is considered to be a modern and safe for natural environment method of machining. It is a method that has been replacing conventional cutting in recent years. This is due to the fact that modern lasers are economical due to the demand for electricity, enable the processing of various materials and are often more effective, the machining is precise, repeatable and the laser as a tool is more durable than conventional. In the experiment described in the a...
