摘　　要：自动化装配技术已经开始广泛应用于飞机装配中,这对机体零件的制造精度提出了更高的要求。飞机蒙皮作为机体上一个大零件,由于其本身有曲率,使其数控加工的实施变得更为复杂。为研究蒙皮机加的工艺实施方法,设计蒙皮机加试验件,借助蒙皮制孔铣切夹具,使用数控机床完成蒙皮试验件的制造,通过开展蒙皮机加精度分析,验证蒙皮机加的可行性,为后续研究奠定基础。Automatic assembly technology has been widely used in aircraft assembly,which puts forward higher requirements for the manufacturing accuracy of body parts.As a large part of the airframe,the implementation of CNC machining of aircraft skin becomes more complicated because of its curvature.In order to study the process implementation method of skin machine addition,the skin machine plus test piece is designed,with the aid of skin hole milling fixture,the skin test piece is manufactured by CNC machine tool,and the feasibility of skin machine addition is verified by carrying out the precision analysis of skin machine addition,so as to lay a foundation for the follow-up research.
