Conclusion

Execution of the course project on machine parts contributes

consolidation of knowledge gained in the study of socio-technical disciplines: theoretical mechanics, the theory of machines and mechanisms, resistance of materials. The subject of course design has the form of an integrated engineering task, which includes kinematic and power designs and the execution of design documentation in the form of assembly and working drawings, as well as the compilation of specifications in compliance with the requirements of the ESKD. The student consolidates the knowledge gained at the stage of calculating and designing a specific drive during course design, which acts as a tool for obtaining the skills and skills that are necessary for the student in his future professional activity.
