Abstract
The problem in the ceramic grinding is a tool failure after a long time operation. It gives a crucial damage to the work piece. Usually, rotational frequency and its multiples are utilized for machine condition monitoring. However, it is difficult for us to clearly observe the frequency components in the ceramic grinding by direct use of the Fourier transform. In this research, we measure the acceleration of the work piece during the grinding process, and the Hilbert transform is employed as a pretreatment of the Fourier transform. Significantly good results are obtained by means of the proposed method.
