Abstract

In the world, technical diagnostics has become an important scientific field of identifying technical condition of machinery and equipment. Each technical diagnostic system has to acquire (measurement) diagnosic signals and analyze information in the signals (analysis) and make evaluations (conclusions) about the current state of the device. The mechanical oscillations occur during operation of the device reflect a very sensitively and accurately to changes in the operational status. Therefore, the measured vibration signals from the device are particularly suitable to the role of diagnostic signals. The article consists of two main parts. The first section presents an overview of vibration diagnosis methods that are being widely applied in industry and in mechanical processing. The second part refers to an experimental study on the determination of stability diagrams of three-axis CNC milling machine of high-speed vibration criteria.
