Abstract
The study deals with forging type rapid prototyping system that automates metal hammering done by an industrial robot. In order to automate metal hammering work, a CAD/CAM system is required to define product shapes and generate tool paths. However, the hammering process differs from the cutting process in that the hammering errors accumulate. Thus, unsuitable work methods threaten to cause both deterioration of work accuracy and sheet metal fractures. However, the relationship between the effects of errors and hammering results has not yet been fully defined. Hence, in this report, the effects of hammering direction on product shape is taken up to make these relationships clear, and a method to improving work accuracy is proposed in order to reduce the potential source of errors. Finally, the usefulness of the devised method is confirmed experimentally.
