According to the production characteristics of single piece and small batch production and combination of production with research in aerospace manufacturing enterprise, opensource middleware is applied to develop the manufacturing execution system with 3-layer architecture. By integrating workflow engine into system main frame, automatic circulation of production process and realtime task states monitor are realized. A complete enterprise data flow is established and the development of informationization in aerospace enterprise is promoted.
The effects of addition element Co on the properties of Ti-Zr-Ni-Cu brazing filler metal are studied. Microstructure and mechanical property of Ti3Al brazed joints with Ti-Zr-Ni-Cu brazing filler metal are also influenced by the addition element Co. The results show that the wettability and fluidity of Ti-Zr-Ni -Cu-Co brazing filler metal are well improved.Addition element Co can significantly enhance the tensile strength of brazed joints.
The inconsistency of quality assurance capability and quality requirement becomes increasingly distinctness, the numerical assurance model or passing aircraft quality information is imminently needed. Based on producing process of quality, this paper makes a main line of designing, process planning, manufacturing of plane, analyzes transforming process from EBOM, PBOM to MBOM. Taking the most representative military plane as example, it puts forward the model of plane manufacturing process BOM quality-oriented.
Some knowledge such as the basic theory, advantages and the current state of FPW at home and abroad are introduced in this paper. The application of this technology is represented, and the necessity of going deeper on the subject is pointed out.
The problem in use of hot-box mold of water jacket for cylinder body is discussed and its sloution is put forward, which will provide the experiences for design.
Optimization of milling parameters is applied to solve the problems of chatter, low machining efficiency and local machining out-of-tolerance due to machining deformation in the fabrication of TC4 integrated impeller of an aeroengine. Based on the cutting force coefficients of TC4 material gained by cutting force coefficient identification tests and the dynamic parameters of the machining system gotten by hammer tests, the optimized cutting parameters are obtained by using the self-developed dynamic simulation software SimuCut for milling and the oversea counterpart CutPro synthetically. The optimized cutting parameters are used in practical milling process, and the machining deformation resulted from the machining chatter and the local out-of-tolerance are eliminated and the machining efficiency is improved.
