Abstract EN
This paper presents a new identification method to identify the main errors of the machine tool in time-frequency domain.
The low- and high-frequency signals of the workpiece surface are decomposed based on the Daubechies wavelet transform.
With power spectral density analysis, the main features of the high-frequency signal corresponding to the imbalance of the spindle system are extracted from the surface topography of the workpiece in the frequency domain.
With the cross-correlation analysis method, the relationship between the guideway error of the machine tool and the low-frequency signal of the surface topography is calculated in the time domain.
