Subject aims expressed by acquired skills and competences

Experimental and special machining methods Continuation of Theory of machining, design and production tools and CAM systems in the machining experiments implementing practical measurement on machine tools designed for the purpose of measuring apparatuses and utilities. Students receive both theoretical interpretation of the individual tasks and their practical implementation in the laboratory department 346, including processing results in the form of programs.
