A320地板梁型面加工工艺优化研究

Study on optimization of machining process for A320 floor beam's profil

针对A320前起落架舱地板梁批量大、型号多,两边侧壁较薄,工件结构刚性差等特性,型面加工的工艺方案存在表面质量差、加工效率低、工件装夹出错率高等问题,结合生产质量提升需求,提出使用分离式专用工装的工艺优化方案,达到提升型面表面质量,提高生产效率的目的。

For the A320 front landing gear compartment＇s floor beam＇s profile have large quantities and many mod- els, both sides of the thin wall, poor structural rigidity and other features, surface treatment process has poor surface quality, low processing efficiency, the higher part of the error rate. With the improvement of production quality requirements, propose the use of separate special tooling process optimization pro- gram to improve the surface quality of the surface and improve production efficiency purposes.
