| Abstract: | Large-scale thin-wall workpieces which are large-scale,low-stiffness and ductile are always used in the aerospace manufacture. A multi-point flexible fixture is developed to solve the manufacture of this kind of workpieces. According to the characteristics of the flexible fixture and the workpieces, a kind of effective method is put forward to optimize the location/support layout of the workpieces, which helps to improve quality of large-scale thin-wall workpiece machining and save fixture cost. |
