Abstract
In this investigation we suggest the new process for micro forming by forging (micro forging). It is reported that processing performance is improved by making a tool or material vibrate in the high frequency by ultra sound waves in case of metal processing, because of the reduction of the load and the decrease in resistance to deformation. In this investigation, a processing tool is made to vibrate at high speed by the ultrasound vibration in micro forging and the characteristics have been investigated. Moreover, in micro forging the flow stress of the material was decreased by heating the specimen to the high temperature. As a result, the processing characteristics of micro forging could be improved. And the processing characteristics was investigated by the changing of the temperature conditions and the lubrication condition in this manufacturing process.
