Condition Monitoring of Single Point Cutting for Lathe Machine Using FFT Analyzer-A Review

Machine tool vibration plays a important role in the surface finish, dimensional and geometrical tolerances of the machined work. Condition monitoring of the lathe machines includes collecting data, such as vibration analysis. Out of these the vibrations occurs due to single point cutting tool have been measured and its effect has been studied. In this paper a preliminary estimation of the most common analysis methods of the vibration signals on 1st and 2nd bearing of a head stock is tried. The tested methods are the typical statistic and analytical analysis method, the Fourier transform, the frequencies spectrum analysis and the Wavelet method. Further testing under variable and/or radial loads is under investigation by the present research paper before a final conclusion can be made. The predicted results obtained from the developed models are compared with the experimental one. Single point cutting tool vibration in lathe macine is an important which influences dimensional precision of components machined, life of the cutting tool is very important. Cutting tool vibration are mainly produced cutting parameters like cutting speed, depth of cut and tool feed rate. In this work, the cutting tool vibrations are controlled in lathe machine where the tool holder is supported with and without damping pad. The cutting tool vibration signals were controlled through FFT analyzer.
