Effect of Vibration on Machine Tool Accuracy and Lifetime

Abstract

The article deals with the influence of vibrations for the accuracy and durability of machine tools. Main content involves the use of technical diagnostics, which includes vibrodiagnostics. Vibrodiagnostics is applied directly in the technological manufacturing process. Technological manufacturing process of machining is the rough grinding of steel balls. Using vibrodiagnostics, information is recorded, which are further evaluated. The evaluation of the obtained information has several parts. The first part deals with the influence of vibrations on the service life of the machine assembly. And it examines the current state of the machine. The second part consists of from finding a connection between the vibrations and the workpiece. Several geometric measurements of the samples were used to find the connection, for example primary profile, undulation surface, profile amplitude and other are compared with the recorded vibrations.
