In the article, the theory, practice and production lessons are integrally connected to the design and construction activities of engineering students by teaching the science of "Machine details" and the factors to be taken into account in the observation and analysis of such lessons. In the preparation of engineering students for design and construction activities, the structure of modern machines, the effective use of the latest advances in science and technology in their design, will be covered by teaching the science of "Machine details". Every designer, every engineer should know the structure and use of machine parts, how to correctly calculate their durability, integrity, heat and corrosion resistance.
