Acoustic Emission and Vibration Analysis of Process of Hard Dry Milling
The monitoring of hard dry milling process is a key issue for ensuring better use of machine-tool capability,Finding a appropriate sensor and signal process method which is sensitive to changes of machining condition,is an essential step towards hard milling automation and computer-integration pursuing high productivity of system and quality of its products. In this study,Sensorial information from relevant sensors(accelerometer and Acoustic emission (AE))is processed by the wavelet transform and wavelet package transform,the result show that AE signal is sensitive to changes of machining parameter(machining velocity) in hard dry milling,but the vibration (acceleration) signal make a slowness responses to this .
