The discipline "Technology of laser sizing (dimensional processing)" prolongs the technological training of specialists, taking into account the specifics of the technological operations of laser treatment, which is connected with the features of the instrument - a laser beam - and their results. The quality of the technological support of the processing determines its efficiency and competitive ability, therefore it is difficult to overestimate the importance of the discipline. In the cycle of technological disciplines the curriculum, which begins with the discipline "Construction Materials Engineering", is extended by the discipline "Technology of Mechanical Engineering", the next step of technological education is this discipline.
