Abstract
The study deals with a development of a forging type rapid prototyping system on the basis of CAD data. In order to automate a metal hammering working that has been operated by human handwork conventionally, an industrial robot having high degree of freedom is adopted. A servo-hammering unit is designed to perform hammering operation imitating that of a skilled worker and it applies impulsive load to the workpiece. A CAM system suitable for metal hammering working is developed. Especially, the posture of the hammer is considered under deforming in progress. From the experimental result, the system can deform the workpieces (aluminum plate) on the basis of CAD data and it having an ability to perform the automatic metal hammering on the basis of CAD data as a rapid prototyping system is found.
