Boeing 787 already began consign user, the pattern of A350 already was decided, a320 and Boeing 737 will change afresh hair, f-35 is entering initial stage of 20 years of production. The plane will become the protagonist that the next makes 10 years, and will be the equipment that is main structure with the metal no longer. The choice of data system and structural design line of business are certain already, the balance between metal and composite material already also came down for certain. Below this kind of circumstance, production technology will increase production further efficiency and reduce cost, although material reachs structural side big decision-making already decided, there still is sufficient improvement in production respect space. Because empty guest reachs Boeing to already will leave generation narrow system plane remit to after 2020, of composite material and metallic stuff contend for cooling already come down, although such, advanced material and the development of production technology still have opportunity, the good luck that is different aircraft only differs. For example, to A320neo and Boeing 737MAX such plane, the good luck that should change material is finite, and structure and technology will still use standard form. But to A350-1000 and 787-10 still more good luck use new production technology. Still lie at present the Boeing 777X in the design makes more change likely, for example, use wing of carbon fiber composite material. These planes are after structure and material decision, still a large number of reducing is reached decrease heavy and craft improves the work. Be like again, f-35 still is in development, the key is put in make improve on, much manual work and quality problem still remain to improve. Spend a large number of time to come for example buy enters fastener, because fastener category is distinct, need reads blueprint on one hand, number is made on envelope, enter fastener place envelope again next. Structure of plane composite material is developing a series of shortening the periodic, advanced technique that reduces cost. For example, the geometrical dimension data that takes out a part automatically from inside three-dimensional design database is the first project of aircraft manufacturer. When plane crop when big or requirement production precision is tall, need automation equipment enters manufacturing workshop to undertake treatment of lay up, cutting, bore is reached undertake examining on product line. Lay up automation is made to composite material for, automation is crucial. Carbon fiber can offer needs performance improvement, but yield must rise, cost ability is reduced. Boeing 787, productivity must improve when A350 and F-35 put into production. As arrive from manual lay up automation lay up, the lay up on the mould became carbon fiber to shove a hand decisively. Lay up speed is crucial, because it decided a needed investment. For example, GKN is producing the tailing edge costal region of the wing the later Liang dynasty of A350 and integration. Every bridge requires half tons of data, will produce 13 roof beam every months. The price of carbon fiber is very high, because of speed of this lay up must tall, raised pressing requirement to the progress of material, craft and face of check proved recipe thereby. Automation has a few kinds of kinds. One kind is to use a robot to locate to lay up, undertake manual lay up " fixed position - lay up " ; One kind is law of automation shop belt, can lay the work of plane or small curved surface, its speed is OK tall, but the way spreading silk that complex part needs automation (AFP) . Both all need special costly device, nevertheless the circumstance is having change, for example, already had automatic shop belt and the combination that spread silk automatically, and " choose - the shop is put " combination. Need not spread small so with AFP. For example, center of national composite material is developing England to spread robot of the type that put a head more, different technology can be used on same time, same work. Center of British country composite material is first use belt two collaboration robot spreads the automation AFP machine that puts a head, this equipment is made by company of French Coriolis composite material, GKN company uses his as projects of next wing of generation composite material. ATK company also is the user of a Gemimi of production company of machine of MAG of family expenses Germany, gemimi is robot of type of one dragon door, silk and shop ribbon can be laid automatically in the changeover inside a few minutes, the method is changeover and butt joint robot. MAG and DLR of German aerospace center are developing GroF1, it is 8 robots on path system, the robot can be in same shop works on filar machine or shop band plane, can spread 150kg hourly. Nextpage is in in the past, an automatic shop is put machine changing when the operation, must stop the machine, change mould, spread fabric with handiwork. When using module type shop to put a head, need not stop the machine change operation. Outside dividing automation lay up, automation bore also is worth investment. Of F-35 outside envelope the aperture of 90% is automatic bore. The machine figure of series of Pang Badi C uses robot of dragon door type to join. The cut after solidify of component of composite material of laser beam machining and bore make bigger and bigger challenge. As the structure bigger and bigger, cut and bore become more and more complex. Carbon fiber is right of cutting tool wear away very serious, can cause fiber loss, and gush water cut can make humidity enters composite material again. Laser beam machining is a kind of solution that has an outlook. Be located in the John with Liverpudlian England rub Er university is combining development with industrial group fiber-optic laser, this laser cost rate of low, cutting is high, stimulate beam of light to be able to move along optical fiber, easily with assemble a robot to realize unifinication. This university uses the 200W fiber-optic laser that JK laser company offers to undertake stiletto demonstrates, obtain nice aperture edge and aperture surface integrality, this kind of surface normally by manual gush arenaceous or blow sand preparation. Except use at cut, outside cutting edge and bore, other utility still has laser mill to cut loss layer board, get on liner of composite material amortization alveolus and thermoplastic composite material solders. As a result of,automation detects the need of concealed body, to F-35 outside modular line asks to use autoverify, measure the smoothness of step, aperture and fastener. Become more and more complex as the structure, the automation nondestructive of composite material examines (statified reach hole) make crucial process. Supersonic examine cistern of general requirement immerge or gush water. The laser that is not a contact now is supersonic examine, can undertake examining remotely plane component part. The EADS innovation factory of empty customer firm and institute of French mine smelt metal examine with supersonic laser certificate of check of the airframe before composite material, the hinge robot that system of this test and verify offers by Spanish Techatom company is scanning head on workpiece accumulate structure of interior of scanning and examination airframe into travel bedding face. Short laser pulse can make workpiece heats to produce ultrasonic thereby quickly, the echo of ultrasonic is received by another laser. CO2 laser can guide to scanning head make laser bundle. The automation of composite material component assembles the automation that auto industry uses to assemble a robot to entering aircraft assembly line to reach economic time in order to reduce cost. The cockpit that Pang Badi plans to use aircraft of series of C of join of robot of type of 6 thin arms reachs machine figure, can save 40h above. The robot of each 12t will use bore and built-in fastener. Buy of 53s of composite material structure enters one fastener, 32s of structure of aluminous lithium alloy. Boeing plans to use new 6 coordinate form automatic bore and mill are cut machine undertake Boeing of cylindrical shell of airframe of 787 composite material assemble. This machine comes from German MAG company, point of a knife uses liquid helium refrigeration, in order to undertake flowing, high-speed grows life cutting. Germany nots production institute of machine of Lao Enhuo's husband and advanced material and CFK Nord research center are considering to use a robot further, they develop a kind to assemble a concept, namely plane cutting and assemble undertake on one scroll assembly line, scroll assembly line uses one little robot shift organism, finish solidify, bore and milling continuously. A multipurpose that can decide a figure of big airlines engine accurately stops move implement first key the design already was finished, establishment of a test and verify will run after 3 years. The value cable length of composite material of craft of solidify of autoclave of low cost blame is very short, supply catenary to have data vendor and machine equipment supplier. Supply the competition inside catenary to make cost is reduced, but should become supply the company inside catenary, autoclave and automation are the obstacle that pits into the introduction. The cost of composite material is the obstacle that the company expands, and automation is the key that drives cost to drop, want to purchase these equipment to need adequate capital. Composite material is not autoclave solidify (OoA) it is the solidify inside the furnace below vacuum bag pressure, be regarded to make old structural member, and avoid to use autoclave, enlarge the way that supplies a base. Although blame autoclave solidify makes work performance is reduced somewhat, but integrated cost effectiveness is tall. Blame autoclave solidify is inferior to autoclave solidify material because of function all the time and development is restricted, but new material appears an as similar as autoclave solidify level, can use at advocate bear force member. For example the composite material of Cytec supplier is such. The blame autoclave solidify that Pang Badi is offerring with Cytec company beforehand jet of Er of production interest of dip makings system the airframe of 85. Handling time all without exception is the same as, cost has however reduce. The Qickstep that Australia develops is the method of workpiece of a kind of solidify, it is to be in close inside the mould, use heat the liquid that reachs pressurization comes solidify workpiece, already began to replace groovy autoclave solidify, in the test and verify on F-35, cost predicts to be able to be reduced 30% . Have supplier of construction of composite material of design engineering capability and supplier of metallic stuff construction to differ, do not answer to press the capacity that compositive business blueprint creates only, and should have design engineering capability at the same time. Because the property of composite material and metal is different,this is. Should make full use of of composite material than intensity, taller than stiffness, fight the good point with corrode sex and can good fatigue resistance, in the product designing these function in design initial stage, make one whole structural member, and rather than receives many snail one case, but premise is to must know the way that send force. The article analysed the last word workmanship of composite material low cost and equipment. Point out reducing respect of composite material cost, production technology is having extensive opportunity, its key is automation equipment. In respect of low cost craft, potential of blame autoclave technology is tremendous, representing development way of future. CNC Milling CNC Machining
