一、引言RP技术的一个主要特点是将成型制造的材料、工装、设备和制造工艺高度集成在一台设备中,一台小小的RP成型机代替了整个一座车间,因而是实现计算机集成制造的极富生命力和发展前景的新技术。以RP为技术支撑的快速模具制造RT(Rapid Tooling)也正是为了加快新产品开发周期,早日向市场推出适销对路的,按客户意图定制的多品种、小批量产品而发展起来的新型制造技术。模具属于一种技术密集型产品,其制作过程涉及材料、工艺、设备等各种因素,按传统机械加工工艺生产,周期长,成本高。而基于RP技术的快速模具制造由于技术集成程度高,从CAD数据 I. INTRODUCTION One of the main features of RP technology is the highly integrated materials, tooling, equipment and manufacturing processes for forming materials in one piece of equipment. A small RP molding machine replaces the entire workshop, which is why the computer integrated manufacturing The vitality and development prospects of new technologies. RP (rapid tooling) is also the rapid manufacturing technology RP to speed up the new product development cycle, the early market to market as soon as possible, according to the customer’s intent to customize the multi-species, small batch of products and the development of new manufacturing technology. Die is a technology-intensive products, the production process involves various factors such as materials, processes, equipment, according to the traditional mechanical processing technology, long cycle, high cost. Rapid tooling based on RP technology, due to the high degree of technical integration, comes from CAD data
