Monitoring of Milling Tool Breakage Using fluctuation Signals in the Spindle Speed |
| |
| Abstract: | A unique technique has been developed for on line monitoring of tool breakage in the milling process using fluctuation signals in the spindle speed. The fluctuation signals can be measured with a photoelectric encoder mounted on the spindle. A schematic diagram of hihg speed sampling of fluctuations in the spindle speed with hardwares is given. Based on an analysis of the speed fluctuation in the time domain, the characteristic parameters are extracted and the information is processed to monitor the tool breakage. |
