基于STEP的CAD/CAPP集成工具的研究
Research of A Step-Based Tool for the Integration of CAD/CAPP

摘要: 长期以来,CAD/CAPP信息集成一直是CIMS系统中的难点之一,且没有得到较好的解决.STEP标准的发展和应用,使其成为CAD/CAPP/CAM系统信息集成的基础.随着越来越多的CAD系统支持STEP标准,开发基于STEP的CAD/CAPP集成工具成为当务之急.文中提出通过支持AP203和AP224应用协议,建立AP203到AP224的模型映射,为不支持STEP标准的CAPP系统提供STEP中性结构到C模型的模式转换器等方法,并介绍了不依赖具体CAD/CAPP系统的"即插即用"型(PNP)集成工具--ApiTool.ApiTool先后用于一系列国家"八六三"CIMS开发项目.Abstract: For a long time,the integration of CAD/CAPP is one of difficulties in CIMS.With the development of STEP standard,more and more CAD systems support STEP standard,so a STEP-based tool for integration of CAD/CAPP is necessary.This paper establishes a model mapping between AP203and AP224protocols by applying STEP.In addition,the paper gives the model mapping from STEP structures to C models.By using these methods,we design a PNP tool——ApiTool which is independent of any specific CAD and CAPP systems.It is used well in some important projects.
