Course detail

Experimental Methods in Forming

FSI-9EMTAcad. year: 2020/2021

The course deals with the specialized methods of measuring and evaluating attendant phenomena in metal-forming. They include mechanical testing, qualitative and quantitative evaluation of measuring of metal-forming and ejecting forces, resistance to plastic strain, strain rates and temperature. The evaluation is dealt with from the viewpoint of individual methods of metal-forming and the operating conditions of the tool. Also discussed is the application of the methods of light and electron microscopy when assessing the morphology of the surface of tools and formed pieces.

Learning outcomes of the course unit

Students will be able to creatively participate in conducting and evaluating experiments required in the technological processes of metal-forming. They will be cognizant of the necessary measuring methods and equipment with automated outputs and evaluation using computer technology.
