飞机是一台非常复杂的机器,由几万甚至几十万个零部件组成,大多为形状特殊的复杂曲面零部件,飞机的结构尺寸大,外形复杂,其结构件主要是钣金件或复合材料壁板件组成的薄壳结构,特点是形状复杂、连接面多、刚性小,在加工、装配过程中都会产生变形。在零部件加工的角度上,飞机零件加工过程中的每一个环节质量的好坏,都会直接影响整架飞机的装配工时。目前数 The aircraft is a very complex machine, composed of tens of thousands or even hundreds of thousands of components, most of which are complex and complex surface parts with special shapes. The structure of the aircraft is large in size and complex in shape. The main components of the aircraft are sheet metal parts or composite parts Shell material composed of wall panels, characterized by complex shape, the connection surface and more rigid, small, in the process of assembly will produce deformation. In terms of parts processing, the quality of each part of the aircraft parts processing process will directly affect the entire aircraft assembly man-hours. The current number
