Research On The Control Of The Cost Of Broaching Process In Tongfa Company

Tongfa company(AVIC Hunan General Engine Co.Ltd.)was founded in April 2011.Its main products include turboprop,turboshaft,piston aero engines.Its business scope includes industry gas turbine manufacture,aero engine maintenance,international parts and components production and aero enginecore p arts and components manufacture.The company is accredited by AS9100 Quality system for international subcontract business,and obtains various NADCAP Qualifications.It has built up the first impeller COE of China.Impeller & Disc COE has core machining techniques or impeller,blade disk,turbine disk,compressor disk installed on small and medium size aero engines like turboprop,turboshaf,turbofan engines.It is also the first company that conquers the broaching technical difficulties of “powder metallurgy superalloy turbine disk” with super-high strength.This paper through the parts mortise branching processing technology to analyze the importance of cost,through to the company nearly 3 years each branching machining process analysis,the cost of the collection,single-channel points parts category calculated broaching machining operations costs.Through field investigation,expert consultation,technical analysis and argumenblood processing process cost a feasible way to improve the implementation of the investigation,through to broach cost,procurement cost,broach broach management costs,reduce the broaching processing process cost.Through collect the aviation industry of various industry public data for studying the contrast,to determine the broaching processing process cost feasiable way to improve.Use in combination with the present situation of company broaching processing process,on the basis of the theory with practice,to assume that simulation of actual case,the final cost optimizat ion of specific methods and measures.Finally,in the comb broaching machining process cost improvement effect,on the basis of prediction and the implementation of security,and analysis about company in procurement,technology,quality and production of s ecurity measures should be taken.Papers through to broach cost,procurement cost,broach broach management costs,reduce the broaching processing process cost.Using advanced processing technology,stable machining quality,the reasonable machining proces s cost to enhance international competitiveness,not only for the processing of all kinds of small and medium-sized aircraft engine compressor disk,more to undertake international wheel processing to lay a solid foundation.In this paper,based on the characteristics of aircraft engine,combining with the typical technology of broaching machining process,a series of improvement method is proposed,to a certain extent for single process cost reduce aircraft engine provides practical reference.
