Abstract: Processes with high energy assistance, such as ultrasonic vibration or local heating, and automatic assembly system in a progressive die were developed for micro metal forming in order to improve process accuracy of micro product due to some size effects in this study. Furthermore, application of textured diamond like carbon (DLC) coating on die surface was attempted to improve the tribological performance for dry micro forming operations.
