Cutting vibration on tool wear state recognition associated with the experimental model

Related to the amount of a specific band isolation and extraction,[link widoczny dla zalogowanych], so you can get the signal from the background of high signal to noise ratio, only with the tool wear state information associated with f, but also by avoiding the selection of the absolute dimensionless parameters. Conducive to changing the cutting conditions in a unified setting to determine the threshold. 174 Vibration Engineering Volume 6, cric, 'na o75u5a ¨ l a oIrl Sun z to the Japanese Special Pa ¨ j ¨ fIJ-u · 2ram,[link widoczny dla zalogowanych], =],[link widoczny dla zalogowanych], smnb ...
