基座组件复杂配合零件加工工艺分析与数控编程仿真 摘要 随着数控技术的发展，数控技术给传统制造业带来了革命性的变化，制造业成为工业化的象征，而且随着数控技术的不断发展和应用领域的扩大，它对一些重要行业的发展起着越来越重要的作用。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, Master CAM,CAXA制造工程师等。 数控技术是技术性极强的工作，尤其在机械加工领域应用最为广泛，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。本文主要通过对零件的数控工艺分析与加工，综合所学的专业知识，全面考虑可能影响铣削的因素，设计其加工工艺和编辑程序，完成要求。 关键词:铣削、CAD/CAM、UG、数控加工 Abstract With the developme
