Use of laser machines for engraving

The diploma thesis covers laser engraving machines topic. In the theoretical part, it briefly covers laser technology and laser engraving in general. It also mentions history of laser engraving, especially rise and development of the laser itself, laser engraving, as well as characteristics of laser engraving machines. A description of laser engraving machines parts and the working principles of laser technology as such are also included. All objects and materials suitable for laser engraving are also described is the thesis. Furthermore, comparison of laser engraving and other traditional methods of micro machining or surface treatment in general is depicted. In the practical part, thesis deals with the goal of finding the exact corrections on the laser engraving machine necessary to be made when using swing method. Major advantage of this method is its time saving ability during the engraving process, but the corrections mentioned above are needed as inaccuracies emerge due to the kinematics and dynamics of the machine. Last, but not least, ascertained corrections were plotted into a graph and a sample product was engraved using the corrections found
