The aim of the diploma thesis is to describe in more detail the measurement of vibrations in the machining process. The work deals with vibrations as a source of information for the analysis of the diagnosed device, which is a source of vibrations, in terms of early detection of an emerging problem that could seriously affect the trouble-free operation of the device. The work is focused on the measurement and vibration sensors used by vibrodiagnostics and their basic principles in measuring vibrations on electric rotating machines and the analysis of the vibrodiagnostic signal in order to detect a fault on the diagnosed machine. Part of the diploma thesis is a theoretical design of a measuring chain for measuring vibrations, which is divided into three steps. The first step describes the preparation of the measuring point and the subsequent location of the sensor. The second step is to create a program tree in the program. In the last third point, the trends created from the measured values are evaluated and the risks are evaluated.
