| Research Abstract |
Technique for detection of damage to and fracture of cold forging tools during forging process by AE technology is developed in the present study. The fractal property of AE amplitude is employed for detecting the damage and fracture of tools. Computer programs for acquisition of AE and continuously and simultaneously calculation of the fractal dimension of acquired AE amplitude are first developed. Then, a proper data processing method for more precise prediction of fracture of tools is proposed.
