Course detail
Experimental Methods
FSI-HE1 Acad. year: 2026/2027 Winter semester
This course covers the fundamental methods for measuring and evaluating the phenomena accompanying forming and machining processes. This encompasses mechanical testing, qualitative and quantitative wear assessment, and the measurement of forming forces, flow stress, strain rates, temperatures and heat, and vibration. These topics are considered in the context of specific forming and machining methods and tool working conditions (including the use of dynamometers, calorimeters, various sensors, and signal processing equipment).
The course also incorporates tribological testing of forming technologies, with an emphasis on the environmental sustainability of lubricants. This includes the assessment of friction, wear, and lubrication mechanisms under various forming conditions, the analysis of environmentally friendly lubricants, and their impact on energy consumption and tool longevity.
Furthermore, the course addresses the application of light (optical) and electron microscopy methods for evaluating the surface morphology of tools and workpieces.
