| Summary: | 碩士 === 中原大學 === 機械工程研究所 === 98 === An average division method which can more early predict the occurrence of
cutting chatter and Built-Up-Edge (BUE) for better pre-warning capability than the
previous developed system was developed in this study. Friendly man-machine
interface was written LabVIEW. The cutting vibration signal was collected in every
second and divided into several pieces. Chatter diagnosis is based on the increase
trend of each 4 consecutive divided signals. Adjusting spindle speed was used to
suppress the cutting chatter. Diagnosis of BUE is based on whether the frequency of
vibration signals decrease proportionally to the number of the cutting edges having
BUE. When BUE occurs, the system will instantly send command to the CNC
controller to stop the machine for cutter change. Experiment results have shown the
developed system can detect the abnormality 1-2 seconds earlier than the previous
system.
