Monitoring of the condition of turning machine bearing housing through vibrations
Mechanical vibration is a phenomenon that occurs very often in the process of metal cutting. It is one of many factors that have a significant impact on the quality of machining and thus prevent a rise in productivity. These vibrations are undesirable not only because they cause noise and dynamic stresses, which result in fatigue and failure of the machine, but also energy loss or performance reduction. An experimental analysis of mechanical vibrations in the machining process is important because vibrations may cause spindle damage, machine tool wear or workpiece wear and may be left with poor surface finish. Therefore, this material is devoted to the study of the impact of input cutting parameters—spindle speed and depth of cut on the formation and size of mechanical vibrations on lathe bearing housings. The measured experimental values of the acceleration amplitude of mechanical vibrations on bearing housings were compared with theoretical values.
