This study deals with the automation of metal hammering using an industrial robot and trial development of rapid prototyping of sheet metal forming. Computer-aided manufacturing (CAM) takes into account feedback considering tool positioning by using a range finder to improve depth and shape error at workpiece corners. Experimental results confirmed that our proposal reduces shape error through tool positioning optimization.
