WHEEL/WORKPIECE CONTACT DETECTION DURING GRINDING PROCESS BY AE SIGNAL
|
| |
|
Summary :
|
|
THIS PAPER DESCRIBES RESEARCH IN THE APPLICATION OF ACOUSTIC EMISSION (AE) TO WHEEL/WORKPIECE CONTACT DETECTION. THIS PAPER DIFFERENTIATES ITSELF BY FOCUSING ON ANALYZING THE RAW SIGNAL INSTEAD OF THE RMS SIGNAL AND BY EXPLORING THE "GRIT CONTACT" INSTEAD OF "WHEEL CONTACT". THE POSSIBILITY AND SENSITIVITY OF DETECTION OF CONTACT WITH THE HELP OF AE ARE DEMONSTRATED. RESULTS OF EXPERIMENTAL EVALUATION ARE PRESENTED. METHODS STUDIED INCLUDE KURTOSIS, SKEW, MVD STATISTICS, ROP, ZERO-CROSSING AND PAGES S TEST. |
