Cutting vibration on tool wear state recognition associated with the experimental model
Related to the amount of a specific band isolation and extraction, so you can get the signal from the background of high signal to noise ratio,[link widoczny dla zalogowanych], only with the tool wear state information associated with f,[link widoczny dla zalogowanych], 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], smnb ...
