摘　　要：由于薄壁零件的结构特点,造成其刚度低,切削过程中受切削力和夹紧力的作用时,极易产生变形,从而影响其尺寸公差和几何公差。本文从工艺流程设计和工艺过程控制等方面,介绍了某大型薄壁铸铝件的加工工艺过程,提出了相应的技术措施,解决了该零件的机械加工问题,为相关高精度薄壁件的加工提供了具体思路和可借鉴的措施。Thin-wall parts have the poor rigidity because of self structure characteristics, parts are easy to occur deform- ation under the function of cutting force and clamp force during cutting process, which will affect dimensional precision and shape precision. The paper introduced machining process of a large type thin-wall parts from the aspects of process flow design and process course control, provided relative technical measures, which solved the machining problems for the part, and gave the concrete idea and constructional measures for machining of high precision thin-wall parts.
