| Course abstract | |
| The aim of the course is to acquire knowledge of manufacturing technologies, evaluate the inaccuracies resulting from the processing, size dispersion and analyse the causes. Students get acquainted with the methods of ensuring precision of machining, calculations of margins, designing and economical evaluation of technological processes of manufacturing of parts. Students learn the specifics of using numerically controlled machines, technologies of assembly and testing of machines, as well as the tendencies of mechanical engineering development. | |
| Learning outcomes and their assessment | |
| 1. Knowledge - of parts, assemblies and machine components (Test 1).
2. Skills - to choose the optimal one from several possible technological solutions and justify its advantages. Skills to develop a part workholding scheme and machining technological sequence, to select a workpiece, to create programs for machining parts with CNC control machines (4 practical works). 3. Competence - in mechanical engineering processes, their role in product manufacturing algorithm development and quality assurance. Competence in the choice of workpiece parameters and their processing technology, ability to develop technology for component manufacturing and assembly of machines (4 practical works). |
