영문 초록

Square dies are widely used for hot extrusion processes with high production rate. Especially, such dies have some advantages in manufacture of aluminum products having arbitrary shapes of cross section, because aluminum alloys can be manufactured without lubrication at a relatively low temperature. The recent development of extrusion technology has brought high precision products with thin thickness. However, the design and manufacture of square dies mainly relies on experience of industrial engineers, it often takes much lead time due to the trial-and-errors of the engineers. To overcome such difficulty, this study develops a method of automatic generation of NC codes for the manufacture of extrusion square dies. This method utilizes both CAD data of a product and database associated with die design parameters, and finally generates NC codes for an aluminum product having an arbitrary shape of cross sections. Specifically, three types of NC codes are generated for : (1) Wire-cut EDM cutting of square dies, (2) Wire-cut EDM cutting of electrodes for die land, and (3) machining of the electrodes. To demonstrate the effectiveness of the method, it is applied to a practical example. The result shows that the method can reduce the lead time for the design and manufacture of square dies as well as eliminating engineers own experience.
