Prediction of instrument resistance by vibration-based diagnostics
The subject of the present research is the method of predicting durability (useful life) of cutting tools. The developed method is based on the approximation model, which describes the characteristic periods of operation of an instrument: running-in, normal operation and wear-out failure period. The model parameters are determined in the approximation of the results of regular monitoring of the sound, generated by the cutting process. The necessary useful life of a tool is one of these parameters. The proposed method of forecasting tool life is proposed for use in cutting machine tools with numeric control.
