Abstract
The goal of this work was to investigate an effect of various signal pre-processings on the outline of the electrical power curve and its influence on the measured cutting force estimation. Two signal processing methods were selected for the needs of the experiment, including digital filter and wavelet transform. The filter used was Butterworth, 3rd order band-stop with the cut-out band from 45 Hz to 55 Hz. The second approach performed was the wavelet decomposition. The carried out results analyses revealed that the properly selected digital processing method of the measured current signal affected by the electrical noise of the constant frequency of 50 Hz does not decrease of information which is carried along by the root signal. The best results were obtained if the root signal has been processed with Discrete Wavelet Transform.
