Basic structure is in ATL machine tool early 20 centuries at the beginning of 60 time, aviation manufacturing industry begins to use carbon fiber beforehand dip makings is one-way belt, use manual shop to put craft to make military airplane structural member. Develop 20 centuries 60 time metaphase, in requirement of aircraft manufacturing industry implementation answer material takes those who expect the layer spreads craft automation to drive, plane of automatic shop band develops a success. Machine tool of the first ATL by American Vought (fertile special) the company is in 20 centuries develop a success in 60 time, with at production F-16 battleplan answer material wing, used 75mm broadband material. To 20 centuries 70 time end, manufacturer of a few renown machine tools begins to roll out commercial ATL machine tool, include plane model (FTLM: Flat Tape Laying Machine) with curved surface model (CTLM: Contour Tape Laying Machine) two sort, component of use width of makings of answer material belt is 25/75/150/300mm a few kinds. Normally, CTLM uses material of wide 25/75/150mm belt, FTLM uses material of wide 75/150/300mm belt. Popularly says, spare parts outline is more complex, jump over hasten to expect at use tape. But machine productivity to raise layer of ATL machine tool to spread, CTLM uses 150mm broadband material more, and FTLM is multi-purpose 300mm broadband makings. Graph 3 wear machine tool of ATL of dragon door structure and CNC MillingATL machine tool high to use open mode to wear design of structure of dragon door movable type high more, its whole structure is very similar the open form that processes application at metallic cutting wears structure of dragon door shift high 5 coordinate CNC Milling(refers to graph 3) . Different is, the common cuts a part with Wu Qie cutter spindle on CNC Milling and actuating device will by ATL machine tool the most crucial function part -- the shop is the first plant institute is replaced; Normally requirement machine tool configures NC of 9-11 axis above to control an axis. General design has X of axis of linkage of 5 numerical control, Y, Z, A, C to use at reference axis of ATL machine tool motion is controlled, also namely, make the shop is the first achieve 5 axes linkage; Additional 4-6 design of NC control axis is the first in the shop on device, show a layer to spread makings of belt of process answer material to convey to put control with the shop with Wu Shi. Graph 3 in shows ATL machine tool is company of American Cincinnati machine tool's inchoate product, basically apply in the production of answer ability component part on missile and military airplane at that time, wait like component of envelope of B-1/B-2 bomber wing. The place before be like is narrated, ATL machine tool basically uses Wu Ping face or the layer shop of answer ability component part makes accurate plane aircraft, include envelope of large airlines wing typically, hang down bridge of costal region of envelope of end envelope, equal remaining part, ala, ala, joist, labour word bridge, rudder, elevator, engine enters gas to be in rectification piece, floor and door window. 2.
ATL machine bed is the first ATL machine tool configures used store to be the first is makings of belt of collect answer material carry, heat, boil pressure stick close, cut, send again wait for a shop to put a function to take makings layer to lay control equipment at the answer material of an organic whole, it is the functional part with ATL the most crucial machine tool. ATL shop is the first normally the design has 5 numerical control to control an axis (UVQDE) , with at answer material is narrated to take makings layer to spread all sorts of craft functions before finishing. The shop of FTLM machine tool and CTLM machine tool is the first structure basically very similar, different is CTLM machine tool design at least one swings with the A that spreads curved surface at the layer reference axis, c turns reference axis is used at the change the shop leads ongoing way. Normally, ATL shop is the first can support 0 ° , 90 ° , + 45 ° and - shop of angle of 4 kinds of standards takes 45 ° direction. The shop is the first all design commonly have convey for expecting makings of drum, belt is oriented device, cut closing device of device, scroll to mix can accuse to heat the main part such as device. (1) reach for expecting reclaim the upper part before device is set in the shop to be the first for expecting drum is much, take makings course position to detect cutting tool of a pair of device, clipping and belt expect carbonado juniors of shrinkage fitting buy is entered take makings directive wheel, then crosses one joint to boil through after of directive wheel bottom press roller, and after assists device to arrive through impaction be the first at the shop the braces of after ministry answers closing quotation roller. Offer makings roller and braces to reclaim through control roller drive electric machinery thereby controallable shop of layer of makings of answer material belt sends makings. The whole apparatus definition that Cincinnati will expect with belt of Wu Fu material this kind sends makings motion is U axis. (2) makings of the belt in cutting setting store to let off Cheng can be cut off or cut place to need point of view, this comes true through designing those who have two clipping penknife to cut unit. Unit of motion of linear coordinate of V of two clipping penknife and Q is on the structure just the same, its shift direction is perpendicular at the way that leads makings advancement. On V axis the design has D axis, and on Q axis the design has E axis, the aleatoric angle that can come true to cut material of answer material belt a need through VD axis and QE axis. What should point out is, cut cut off answer material itself merely, and do not cut off back stock. (3) add shop of shrinkage fitting buy to be the first on can accuse to heat device in order to controls makings of answer material belt to warm up (Cincinnati machine tool is lukewarm accuse limits 26-43 ℃ ) the viscosity with necessary generation. Can accuse to heat device and roll press fitting buy to form a harmonious whole, can make effectively take can good land is stickup between makings layer be together or stickup go up in mould face (when ground floor) , can squeeze the air between the layer. (4) closing device shop is the first go up boil press roller to expect with the tape that puts at squeezing ramming shop the adhesion between layer of effective implementation and clingy workpiece face. Impaction is normally direct by press roller to offer, layer shop joint boils control pressure, cincinnati machine tool is right 27-133kgf is when 150mm of answer material bandwidth, it is 27-173kgf to bandwidth 300mm. Normally, rolling pressure is programmable, can input by operation personnel through console. In addition, ATL machine bed is the first all install stock photoelectricity to take makings blemish to detect commonly device, once detect,arrive in layer shop process take makings blemish to control a machine tool to stop a shop to move. The equipment of ATL of ATL machine tool in industrial application from 20 centuries since be born in 60 time, 10 years via enumerate continual development comes 20 centuries 90 time end, in machine tool structure, layer control of shop craft, lay up, shop is the first the respect such as the answer material range that the function changes level, process designing to reach its to use obtains great progress. What put productivity and its dependability as level of automation of ATL machine tool, shop is farther rise, those who obtain a plane to make an user is general approbate, drove the real industry application of ATL machine tool. To at present till, the ATL that already had many 60 commercialization about applies in aircraft industry. The manufacturer number that can provide commercial advanced ATL machine tool to the user now is not much, basically company of American MAG Cincinnati, Ingersoll, Spanish MTORRES company and French FOREST-LINE company wait for name of a few moves to machine machine tool manufacturer, and American ADC (Automated Dynamics Corp.
) , answer ability component part machines a certain number of major such as Entec company equipment manufacturer. 1.
Plane of high-end shop band (HCTL) in answer ability component part the show one's skill in making about from on 80 time begin the century to this century first (2001) , boeing company already purchased equipment of nearly 20 ATL, the wing envelope that uses battleplan of plane of the person that enter at production B-1/B-2 bomber, naval A6 and air force F-22, v-22 Osprey is inclined envelope of ala coming back, and the answer ability component part such as wing of transport of C-17 for military use. Boeing 777 planes (1995) complete the empennage envelope of answer material, its average remaining part / hang down also machine tool of CTLM of series of CHARGER of use Cincinnati company machines empennage envelope is made. Dallas of American Vought airline (Dalasi) the factory also holds stock Cincinnati firm large twin store of double dragon door is the first structural CTLM, produce C-17 with Wu Sheng level of transport of large-scale for military use stabilizes alar envelope wainscot, wainscot is long 12.
9m, thick 15mm, alar root ministry is wide 3.
6m, wingtip is in board thick only 2.
5mm, every plane needs 4 (up and down each 2) , can spread at the same time put 2 parts, year output makes an appointment with 60. The CTLM of new generation of CHARGER series Version 5 that company of Cincinnati of machine tool manufacturer develops, be called plane of band of advanced curved surface shop (HCTL: High Contour Tape Layers) . This HCTL uses structure of shift of door of low slideway dragon, slideway height can press an user effective demand design. Accordingly, with the graph in above paragraphs photographs of 3 inchoate ATL machine tool that show Cincinnati are compared, have better open sex, fast sex and structural stiffness, suit to be mixed at all sorts of flat, outline more change of geometrical appearance in large size plane medium, carbon fiber / the automatic layer shop of answer ability component part machines epoxy resin, the shop takes speed to be able to amount to 50m/min. Design of Nextpage this machine tool has 10 NC to control an axis, among them 5 (XYZAC) with at linkage of machine tool reference axis motion is controlled, 5 are used at shop belt fillet makings layer extends control, the machine tool configures new generation CNC to control systematic CM-100. Basic journey is X axis 3.
6m, but times add lengthen, at the same time every 3.
What 6m part can grow 300mm to move in order to add X axis way is flexible; Dragon door width is adjustable, standard type is 5m, z axis metre can be adjusted according to real need, a position of axle carries the head at the shop, can realize curved surface layer to spread, basis of crossbeam slideway height needs set actually. HCTL shop is the first it is easy to match installation and operation again, allow to lade simply from flank quickly wide 300mm diameter amounts to 650mm to take charging tray, the shop is the first hardware design makes 150mm or 300mm broadband charging tray change fast. The shop is the first return a design to have options of cutting tool of ultrasonic of a 20kHz, cut thick amount to 15mm) . Accordingly, this options makes the user can be directly on ATL machine tool have cut to answer material workpiece, implementation is cut and the shop takes working procedure to be operated on same table machine tool, do not need to be in undertake cut working procedure is operated technically on machine tool of answer material cut, avoided to turn possibly foreword awaits and the new fixed position holding clip when be machined on machine of answer material cut, can shorten thereby production of answer ability component part is periodic. What should point out is, need intermit shop belt to move when having spare parts cut, bring about a shop to take productivity to be reduced somewhat thereby. But the place before be like is narrated, by at do not need to turn working procedure undertakes cut is operated, the productivity that consequently answer ability component part makes still can be raised. Up to now, MAG Cincinnati company already offerred the ATL machine tool of all sorts of norms to amount to many 40 for aviation industry. Boeing company in its answer material makes a center inside already first after installed 8 ATL machine tool (it is Cincinnati company HTLM 2 times among them, right original the CTLM of 2 Cincinnati undertook updating transforming) , with Wu Bo sound 777 with 787 planes the layer of the component part of answer material whole such as envelope of box of the ala central, wing extends production. The ATL facilities of Cincinnati company also provides empty customer firm, wait for the production of structural member of wing answer material with transport of A320 of Wu Kong's guest, A330, A340-500/600, A380 and A400M for military use. 2.
Component part of ability of Liang Fu of production wing of ATL machine tool is contemporary and large A400M of transport of for military use by drive of engine of airscrew of turbine of 4 power 7500kW, 8 airscrew leaves that through decelerate device drive makes an appointment with 250kg every again (composite material is made) , 850r/min of rated rotate speed, gross generation exceeds 8, effect of 700Nm torque strength is using CFRP complete on the wing bridge component part that answer material designs. Component of this wing bridge is made by company of GKN space navigation, the carbon fiber of company of data of project of use England Cytec / epoxy resin increases model beforehand dip makings 997-2, alar bridge grows 19m, alar bridge cent is 12m/7m before two paragraphs, cent of after ala bridge is 14m/5m two paragraphs, two paragraphs a C clevis connection that makes through composite material, the longest odd Duan Yiliang is 14m, wide 1.
5m. The machine tool of ATL of Spanish MTORRES company that these alar bridge are applied 20m long lathe bed produces, use answer material to take makings is thick 0.
25mm, use a layer to pave way, thick amounts to 21mm, every put to crisscross shop with different fiber in order to obtain first-rate component intensity and hardness, yield of shop free captive animals is 25kg/hr on average, highest can amount to 36kg/hr, and use artificial shop to put it is only 0.
75kg/hr. As we have learned, former bearer of company of GKN space navigation is versed in the shop puts 14m to grow alar bridge to need 7-8 day, use after of ATL machine tool to need 24hr to be able to be finished only; Artificial shop puts bridge of ala of the shortest 5m to need 180 Hr, of use ATL time-consuming and mere for 90min. Company of GKN space navigation thinks, use ATL automatic shop puts the machine tool to combine application at the same time DDF of craft of double diaphragmatic figuration (Double Diaphragm Forming) make part of component part of an answer ability, want fast 25-50 than using a person to be versed in the layer is spread times. What Spanish MTORRES company makes is open model plane of band of shop of TORRESLAYUP of movable type of door of dragon of low course high speed, the design has axis of 11 numerical control, used modular design technology, can undertake configuration according to user demand; Answer material takes width of use 75/150/300mm standard makings. 3000-5000/1000-6000mm/300-1500mm of journey of axis of machine tool X/Y/Z, 185 ° of C axis ± , a axis ± 22.
5 ° ; 15-45m/min of speed of linear axis feed, ± of fixed position precision 0.
08mm, deserve to cutting tool of two small-sized ultrasonic is used at take makings cut. MTORRES shop is the first can provide the biggest impaction capability, do not need to use vacuumize method often to obtain optimal impaction result. In addition, the shop is the first on the design has inside testing system of blemish of makings of the belt that fit pattern, design useful the options such as the laser smooth proscenium that checks at component part outline. 3.
"Duplex operation foreword " wainscot of envelope of production wing of ATL machine tool FOREST-LINE of France of answer ability component part (Fuleisite - in inside) the company is in 20 centuries 80 time end (1988) developed open model the ATL machine tool that wears structure of dragon door movable type high. The WR ATLAS that rolled out working procedure of the sheet that be called 2006 (Automatic Tape Laying System) plane of automatic shop band. The shop is the first can match options of ultrasonic cutting tool, implementation will cut working procedure and shop to take working procedure to be operated on same table machine tool, FOREST-LINE will shop of working procedure weighing sheet takes a system. Answer material layer spreads the ACCESS/ATLAS of the foreword of the duplex operation that be called of this company newest development system, be by advanced makings of answer material belt edits / clipping system ACCESS (Advanced Composite Cassette Edit/Shear System) with automatic shop belt two equipment comprise systematic ATLAS. This is one kind takes answer capable person makings clipping working procedure and belt to expect automatic layer spreads the answer ability component part with separate process to make a technology, reason is called " duplex operation foreword " or say " two footwork " ATL equipment. ACCESS is special before undertaking taking expecting the layer is spread at ATLAS, through carrying out software to differ by component part lay up asks to undertake editing clipping to original band makings, produce the material of lay up belt of complex border, can flotsam of automatic purify clipping, the area with editor nice clipping expects be installed to be in box of drum of makings of finished product belt, back paper is set between makings of answer material belt, drum box is piled up of a corresponding form identify in order to offer opportunity of ATLAS shop belt. Come so, pass ACCESS equipment support, ATLAS machine tool can achieve complex outline appearance not only the automation shop belt of answer ability component part, raised a shop to take productivity at the same time. Normally, shop of ATLAS of supportable much stage takes an ACCESS facility accident goes, form much chance of component part of a kind of answer ability to produce production environment. Plane of ATLAS shop band uses numerical control 5 axes linkage (XYZBC) wear design of structure of dragon door movable type high, journey of standard X axis 8.
3m, but enlarge is long, y axis journey but optional 4.
15/5/6.
5m, z axis journey but optional 520/750/1000/1200mm, b swings 30 ° of axial ± , ± of C runner shaft coming back 200 ° . X/Y/Z axis all introduces drive of linear electric machinery, 60m/min of X/Y axis speed, acceleration 1.
5m/s2, z axis 15m/min, 16000/min of B axis rotate speed, 40000/min of C axis rotate speed. Its shop is the first spread tall productivity to realize a layer only and design, offer 675mm of charging tray diameter, belt makings can be as long as 800-900m, allow to use 50/150mm broadband material, support 0 ° / 45 ° of ± / shop of angle of 4 kinds of standards takes 90 ° direction. In the meantime, the design has double ultrasonic to cut knife and shop of layer of concave and convex outline to get used to systematic options oneself. In addition, to raise ATL machine tool productivity is mixed lay up is flexible, FOREST-LINE ATLAS machine tool still can comprise a kind to be able to come true " twin store brings technology " the ATL machine tool that twin store is the first, be about to shop of aforementioned simple working procedure is the first and shop of duplex operation foreword is the first compositive design is the first in a shop on, former allow to use wide amount to 300mm belt to expect the shop puts those who make simple rough sketch answer ability component part, latter is used through independence beforehand of clipping the widest amount to 300mm belt to expect the shop puts those who make complex outline appearance answer ability component part. 3 water chestnut of Japanese are versed in again (MHI) be versed in again with Fuji (FHI) purchased FOREST-LINE this kind of ATL, with Wu Bo sound the treatment of wainscot of envelope of face of ala of fluctuation of answer material wing and alar box makes 787 planes. The ATL machine tool of FOREST-LINE is the earliest south France manufactory of plane of especially empty passenger applies at ATR plane of component of answer material wing make, after continues to apply in A340-600 keel roof beam, A380 again in the center of central ala box and A400M of transport of for military use the production of the answer ability component part such as alar box. According to the report, at present especially empty guest flies to machine manufactory to already was configured south France have 6 ACCESS facility, plane of band of 9 ATLAS shop. 4.
The company of machine tool of Ingersoll of United States of ATL machine tool that with Wu Fu shop of material whole component part puts treatment also is ATL/AFP equipment one of main manufacturer, the ATL machine tool that this company makes uses 25/75/150mm broadband material, face of usable Wu Ping or simple curved surface kind shop of component part of answer material whole puts treatment, also be to use numerical control 5 axes linkage (XYZAC) wear design of structure of dragon door shift high, 30m/min of speed of X/Y axis feed, z axis 15m/min. A axis 10r/min and C axis 20r/min. The shop of this machine tool is the first also is special spread tall productivity to realize a layer and design technically, include diametical 635mm to offer charging tray, drive of feed of two-way belt makings and belt expect tensional control, braces reclaims reel, end zone comes off implement, end takes impaction to assist makings of device, belt to heat calibration of makings of belt of axis of system of system, laser coordinate calibration, T- , double ultrasonic cuts a knife. In the after that summarizes afore-mentioned application, most what after should point out is, what the basis uses a target actually is different, ATL machine bed is the first the function changes level and complex rate often is different. Meanwhile, also can see in the discussion from inside preamble, although,the ATL machine bed that different equipment manufacturer produces is the first each has his strong point, have distinguishing feature alone, but with respect to its it is basic and identical however basic function.
