飞机制造具有尺寸大、零件形状复杂且种类繁多、气动外形严格及加工精度高等特点。目前随着我国数字制造技术的发展及其高端数控机床技术方面的突破,机加件已实现了全数字集成制造,但是复杂零件由于柔度大,难以使用传统夹具夹持,因此难以实现全程数字化的柔性制造。国内各大航空集团主要采用模线样板等传统的模拟量工作法,应用仿形架固定复杂零件以实现后续的机加工,大大增加了飞机制造的准备周期和成本。随着机种的增加,其夹具也占用了企业大量的管理资源和库存面积。因此,复杂零件装夹制造已成为飞机全机数字化制造、装配的瓶颈。另外,在轮船、动车制造过程中,也存在相同的技术难题。 Aircraft manufacturing has the characteristics of large size, complex shape and variety of parts, strict aerodynamic shape and high processing precision. At present, with the development of digital manufacturing technology in my country and breakthroughs in high-end CNC machine tool technology, machined parts have achieved full digital integrated manufacturing, but complex parts are difficult to use traditional fixtures due to their high flexibility, so it is difficult to achieve full digitalization flexible manufacturing. Major domestic aviation groups mainly use traditional analog quantity work methods such as mold line templates, and use profiling frames to fix complex parts for subsequent machining, which greatly increases the preparation cycle and cost of aircraft manufacturing. With the increase of machine types, its fixtures also occupy a large amount of management resources and inventory area of the enterprise. Therefore, the clamping and manufacturing of complex parts has become the bottleneck of digital manufacturing and assembly of the whole aircraft. In addition, the same technical difficulties also exist in the manufacturing process of ships and trains.
