Course detail
FSI-HE1Acad. year: 2022/2023
The course deals with the basic methods of measuring and evaluating the side-effects of machining and metal-forming. They include mechanical testing, qualitative and quantitative evaluation of wear, measuring of cutting forces and resistance, metal-forming and ejecting forces, resistance to plastic strain, strain rates, temperature & heat, and oscillation. The evaluation is dealt with the viewpoint of individual methods of machining and metal-forming and the operating conditions of the tool. Applications of the methods of light and electron microscopy when evaluating the morphology of the surface of tools and workpieces are discussed too.
