The credit module "Special elements and equipment of laser technological complexes" extends the technological training of masters in the direction of technological equipment of laser processing operations. The purpose of studying the content of the discipline is to provide specialists and masters with the knowledge necessary for the practical realization of laser processing operations on the side of the adaptation of the universal laser technological equipment (LTE) to the requirements of achieving the best processing results at the lowest cost. This relates to facilitating the control of LTEs, beam manipulations and blanks in the processing area, to increase the efficiency and performance of the operation, and to provide new operational properties to the processed products.

The credit module relies, in particular, on the knowledge that a student gains in mastering the content and skills of credit engineering and design training modules. The first one can determine the directions of an additional act for a technological operation, and the second one - to carry out the design of laser elements, optical systems, measuring techniques and automation of individual transitions and operations in general.

Additionally, in the practical mastering of discipline materials in the form of performing individual tasks, students master the ability to search in the designs of objects that have signs of solutions that need protection as an intellectual property, and prove this ability to obtain a patent.
