摘　　要：CAPP作为CAD/CAPP/CAM集成的重要环节,目标是实现工艺编制自动化。而获取零件特征信息是编制规范化工艺方案的关键。相似零件特别是轴类零件具有相同或相似的特征信息。在研究分析CAPP系统优势及国内外发展现状的基础上,提出适合轴类零件的CAPP系统,该系统应用相似零件组的典型工序模板。具体零件所需工序在典型工艺模板基础上进行优化得到,由零件的特征尺寸信息,根据尺寸反推原理就可以得到完整的工艺规程。CAPP is the important step of CAD/CAPP/CAM integration,which aimed at automation of process planning.Extracting parts feature information is a crucial part of establishing standardization process planning document.However,similar parts,especially shaft parts,possess similar features.Based on the investigation of superiority and current situation both inland and outland,we exploit this CAPP system for Axial parts,useing the typical process templates,optimize the typical process templates when come down to Specific parts,and then receive a complete set of process for special parts.Utilize the Principle of Size Backstepping and size information of the parts,the whole CAPP document is got.
