Course abstract
The aim of the study course is to provide a set of practical skills in digital control machine tool management, preparation of CNC control programs. Practice is carried out in the laboratories of the Motor Vehicle Institute. Students are assigned by the order of the Rector and obey all the rules of the study process. Students learn the first skills in CNC turning and milling. Students strengthen their first skills in turning, milling and learn the basics of technological process development in turning and milling.
Learning outcomes and their assessment
1. Knowledge - knows the technical characteristics, construction and equipment of CNC working machines - report on the practice;
2. Skills - know the technical parameters of the CNC machine, its structure, the necessary tools and application possibilities - test;
3. Competence - able to choose and justify the conformity of production machinery to production conditions and production volume - test.
