The study presents a procedure for detecting tool failure in drilling of CFRP/Ti6Al4V aeronautical structural components. To accurately detect tool breakage, a method based on the Daubechies 2 Discrete Wavelet Transform (DWT) is proposed to analyze the spindle power consumption signals in the time-f...
