Course detail
Experimental Methods
FSI-HE1Acad. year: 2026/2027
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.

Rules for evaluation and completion of the course
- Attendance in lectures is recommended. Attendance in exercises is compulsory. Attendance at lessons is required and checked by the tutor. One absence can be compensated by attending a seminar with another group, or by elaboration of substitute tasks. Longer absence is may be compensated for via special tasks by the agreement with the tutor.
The attendance to the seminar is regularly checked and the participation in the lesson is recorded.
Aims
Students will be able to creatively participate in performing and evaluating of required experiments in the technological processes of machining and metal-forming. They will be able to recognize proper measuring methods and equipment with automated outputs and evaluation by the help of computer technique.
