MašZP018 [GMASP018] Practice in Metal Processing II

Course abstract

The purpose of the study course: to provide a set of practical skills in the management of numerically controlled machine tools, in the preparation of CNC control programs. Educational practice Metalworking takes place in the educational workshops and laboratories of the Institute of Engineering and Energy. Students are assigned by order of the rector and obey all the rules of the study process. Students strengthen the first skills in turning and milling and learn the basics of developing technological processes in turning and milling.
