Synopsis:

The course introduces students to the technical means, methods and practical experience in the diagnosis obráběcícch machines. These include the basics of vibration diagnostics. Emphasis is placed on the measurement according to ISO standards and CSN implementation and practical tests. Furthermore, introduction to the measurement of dynamic properties of machine tools and evaluation of their operational vibration.
