Research Abstract

The purpose of this study is to elucidate the relation between servo press motion and friction by the measurement of friction between the work and the tool surface using a miniature friction sensor and to apply the results to friction control forming. For this purpose, a miniature friction sensor has been designed and manufactured. For the heat proof of the sensor for the application to the hot forging, heat proof strain gauge and bonding has been challenged. Forging test has been carried out to investigate the deformation around the punch corner. A punch to insert the friction sensors has been manufactured to detect the friction around the punch corner.
