摘要

本篇设计是Y向箱体加工工艺及编程，Y向箱体零件的主要加工表面是各表面的铣削加工，内表面的铣削加工和及内孔 , , 的镗削加工以及 直孔的钻削加工和8-M6-6H螺纹孔的钻、攻加工等。一般来说，保证平面的加工精度与保证孔系的加工精度相比，保证平面的加工精度比较容易。孔径加工都是选用专用钻夹具，夹紧方式一般选用手动夹紧，夹紧可靠。因此生产效率较高。能够满足设计要求。

 文章的重点在于对Y向箱体的工艺性和力学性能分析，对加工工艺规程进行合理分析，对Y向箱体进行加工工艺的规程设计，包括了Y向箱体的数控铣削加工，并且介绍了数控铣的加工工艺及编程，以此Y向箱体进行数控铣的加工工艺编制和数控编程的设计，经过实践证明，通过合理地安排该Y向箱体的机械加工工艺路线，能够加工出合格的Y向箱体零件，以便于其他零部件的装配。
