Online Detection and study of Cracks in Grinding Hardening

摘要：

　　Grind-Hardening technology is a new technology for cutting that combines grinding theory with quenching theory,and the heat produced during the grinding process has a great effect on the surface quality of the parts.This paper take advantage of method of acoustic emission testing to test the grinding hardened partsby online or scene The wavelet packet is used to denoise the signal,then the denoising signal is analyzed to judge those grinding cracks or defects that may appear on the surface of the parts,andbesides,this method is easy to do.
