P51G箱体零件数控加工程序设计 摘要 P51G箱体零件数控加工程序设计主要研究的是利用UG NX软件模拟加工中心对P51G箱体零件的数控加工过程，并据此自动编写出数控加工程序，应用于实际加工中心的生产过程中。在此过程，借鉴普通机械加工的加工技术要求等方面的因素，综合制定了零件的加工工艺总体方案，主要应用UG NX软件的三维建模以及加工设定模拟功能，对P51G箱体零件进行必要的建模，设定几何部件和毛坯，在加工模块里对数控加工过程设定合理的符合实际生产的参数，包括主轴转速、进给速度、背吃刀量和刀具补偿等，生成刀轨并进行3D动态模拟，最后经后处理定义生成零件的数控加工程序，进行检查与优化。P51G箱体零件的数控加工程序设计成功能够说明数控系统自动编程的可行性，为现代化机械生产企业提供更加方便快捷的机械加工方式，有助于节约更多的人力物力，并且有效避免了人工编写大量冗杂程序时出现的错误。总之，数控加工技术的应用会作为现代化智能化生产的主力而广泛应于各大加工领域。 关键词：数控加工；UG NX；三维建模；后处理 ABSTRACT The mai
