板类配合件的加工工艺设计 摘 要 随着科技的发展，数控技术也在不断的发展更新，现在数控技术也称计算机数控技术，加工软件的更新快，CAD/CAM的应用是一项实践性很强的技术。如像UG , PRO/E , Cimitron , MasterCAM ,CAXA制造工程师等。数控技术是技术性极强的工作，尤其在模具领域应用最为广泛，所以这要求从业人员具有很高的机械加工工艺知识，数控编程知识和数控操作技能。本文主要通过铣削加工薄壁配合件的数控工艺分析与加工，综合所学的专业基础知识，全面考虑可能影响在铣削、钻削、绞削加工 中的因素，设计其加工工艺和编辑程序，完成配合要求。 关键词:板料配合件；工艺；CAD/CAM With a sheet of process design Pick Abstract With the development of science and technology, numerical control technology in the development of numerical control technology is updated, now computer numerical control technology, processing software updates faster, CAD/CAM application is a practical technique. Like UG, PRO/E, Cimitron manufacturing engineers, MasterCAM CAXA, etc.Numerical control technology is highly technical work, especially in the mold domain most widely used, so the requirement of high practitioners machining technology knowledge, CNC programming knowledge and skills. This paper through the milling process of thin-walled with numerical analysis and processing, the comprehensive knowledge of basic specialized knowledge, comprehensive consideration may influence in milling, drilling, cutting processing of factors, its processing technology and editing program, complete with requirements.
