Title The Blanking die CAD and Layout System
Abstract
The die technology has become one of the important measures of the manufacturing level of a country. The layout is the most important and the toughest technology for the design of blanking die. Obviously, the computer-aided layout will be as advanced technology to increase the design efficiency and quality of the blanking die .In order to improve the efficiency and intelligence of punching die design, we take CAD as developing platform, to research the intelligent punching die CAD system. The whole frame of the system is designed, and the key techniques of the system modules are discussed in detail. The optimal layout algorithm of work pieces is researched. Based on polygonal vertex algorithm, better polygonal vertex algorithm is constructed pointedly, which is simple and effective. By use of the algorithm four basic layout modes of strip are realized. The layout module is developed with VB. In the end, the paper concludes a summary and proposes directions for future research.
