Systematic service cuts tubal machine cut at blaze numerical control maritime platform conduit wears pipe fitting, the system inputs the structural single track that is marine platform to pursue, systematic output wears cut sheet for conduit graph. Process the parameter information of a need through identify directly and be being extracted, all sorts of geometry parameter that automatic computation cuts tubal machine place to often want, the geometrical parameter consideration that final basis receives as string of 1000 cash line and scale gives conduit to wear sheet graph. This system belongs to the system of automatic process designing that is based on a graph, take a kind of application of CAD/CAM unifinication technology. The production of marine platform is the project with high content of a giant, complex, technology, conduit wearing is the crucial structure in marine platform, the stand or fall that guides pipe rack builds mass will affect the integral quality of platform construction directly. Accordingly, the efficient, accurate treatment that completes pair of conduit to wear component part is the necessary premise that builds marine platform, and the organization that platform metal conduit wears component part parameter and computation, of wall of the edge after conduit wears cut develop a plan namely odd the graph generates the system that must ask to an automation, intelligence is changed to finish. In the production of maritime in the past platform, metal conduit wears the data data of component part to basically manage artificially according to cloth blueprint, the intelligence that did not list person computer changes administrative scope, accordingly, before the every time treatment to component part, in the software that should input all sorts of parameter of component part to machine a machine to control artificially according to blueprint. Next, the between geometrical parameter that conduit wears is to pass factitious calculative method to be defeated by person system normally, at the same time odd of a graph generate also must rely on type of factitious input pipe fitting to finish. This increased to make the trival sex of the process undoubtedly, and reduced manufacturing efficiency. The article is aimed at above malpractice, own research and the maritime platform conduit that develop automation, intelligence to change wear sheet the graph makes a system automatically. One, maritime platform conduit wears system of odd coil construction maritime platform is wear the frame structure that forms through soldering by a certain number of root conduit, the form that conduit wears is varied, include a valve, board, the structure such as annulus, awl. The part that in be being made as a result of maritime platform, uses all is designed by AutoCad, the result is three-dimensional graph commonly, but because marine platform is a giant, complex system, if use three-dimensional graph to show the integral structure of platform, what inevitable meeting makes the graph changes is unusually complex, reduced intuitionistic sex and operation sex. What accordingly this systematic place handles directly is single-track graph, namely each spare parts expresses with one dimension graph, almost all spare partses are abstract for line segment, if the graph is shown 1 times,add up to conduit to wear structural single track to pursue to make the same score. The other information of the spare parts joins the database that deploys for place of this spare parts through the means of manual input in, need to pass one-time input only can get sth done once and for ever, the computation of the memory that the job of other includes basic information and geometrical parameter and odd of a graph generate finish automatically by the system entirely. 2, this system uses systematic function and implementation method CAD software regards the graph of the platform that prop up as system of automatic process designing, it its have rate fast, precision is tall, intuitionistic the gender is good, use the good point such as convenient, facilitating examination. CAD system pursues in spare parts single track (include a valve, board, cone, model plume, annulus) in deploy a database, process the parameter information of a need through identify directly and be being extracted, automatic computation cuts all sorts of geometry parameter of need of tubal machine place, the geometrical parameter consideration that final basis receives as string of 1000 cash line and scale gives conduit to wear sheet graph. This system belongs to the system of automatic process designing that is based on a graph, it is a kind of application of CAD/CAM unifinication technology. If the graph is shown 2 times,for the system overall function module pursues. The basis develops the characteristic of the language individually, the system chooses nest to regard development as the language at the VLISP of AutoCAD interior, can call command of almost all AutoCad directly, have the basic structure of general and advanced language and function namely, the powerful figure that has general and advanced insitute of language to do not have again handles a function. 3, spare parts information generates what conduit of module ocean platform wears to make include a variety of member, have a canal, board, the structure such as cone, annulus, profiled bar, in wanting to classify these structural parameter the input to pursue to single track, must pass reasonable interactive letter urgent interface namely the dialog box will come true, in protecting the information of the input permanently existence single track to pursue, and ask grant specific information atone for specific structure, click a certain structure to be able to call each information that gives it, with benefit at examine or be being revised. Because be in the process that the system handles, the document that systematic place handles all is DWG file, it is the database that AutoCad is generated in the graph and uses in the editor, the main content that it deposits is the geometry that makes a figure information and other concerned information. DWG this kind of database is quite chic, the structure of the database allows an user to build his, allow a variety of possibilities of the structure " blame graph information " data. Of this kind of data building basically is to use " attribute " , " patulous object database " and " dictionary " 3 kinds of big functions. In the project of work out program, choice graph dictionary will manage a database. In user unit process of cargo bandling, wanted to find relevant graphical target only, can find the blame graph data logging related these and this graph. Type of data of graphical dictionary practicable is quite rich, almost all Visualisp data can be used simplified the program writes difficulty, can accomplish an user to want how to can keep data structure almost, and data basin can comparative big. Graph of an odd delay can store many graphs dictionary. Deploy dictionary of a graph to every pipe fitting namely, dictionary of a graph can coexist many records. Express to be pipe fitting of a line segment general in single-track graph like some pipe fitting other information input arrives in this hypostatic graph dictionary, input statement is as follows: With (one LIST EN) can inquire one LDATA of VLAX information of this pipe fitting: Denotive meaning is place: Lever paragraph of number: 1, right node: A, right bag board: Without, tubal diameter: 609.

6mm, the wall is large: 19.

05mm, lever primary color date: 7, lever date: 1, zun Jie orders number: B, left bag board: Without, lever type: Canal. After to program is finished, its to load arrives in the AutoCad group that start, after running AutoCad every time so, this program will finish automatic to load. When inputting spare parts information, key in the InPut of command losing a person of to program, begin to take staff, every take a staff (should catch target area to have by accident, or when knocking other clavier by accident, undertake circular catching, till catch successful) , lever highlight, indication graph shows input dialog box 3 times. In the graph, the editor casing content that Gao Liang shows is the information of concerned canal structure, other editor casing is not usable. If click sheet to choose the structure of other spare parts in casing, be like board, criterion with board relevant editor casing if Gao Liang of groove horn, splint criterion shows, editor casing is other to be able to be not used. Manage together, the spare parts structure of other parts corresponding at pertinent spare parts information. After data input ends, criterion lever brightness returns to normal, but lever color becomes angry (but variable beard remembers primary color) . In addition, all model information that when single track pursues medium is inputted after finishing, restore every lever Yuan Yan is lubricious, and file, if have need, in can keeping the information of the input person data file at any time. 4, the important basis that module of computation of parameter of spare parts geometry guides parameter of pipe rack geometry is to undertake CNC machining. Main geometrical parameter includes: Lever the axial angle of cut between, turn round horn, prejudicial, job to nod deflection (wrong heart) . If the graph shows 3 times,its define: (A of 1) axis angle of cut: Raise the included angle between tubal axes and director axes. (2) turns round horny B: That one aspect of the matter that is in charge of axes to be used at computational axis angle of cut is raising tubal cross section (namely sectional circle) those who go up is umbriferous with 0 degrees of lines (when initiative cut, cutting torch of that a bit as sectional as what pass this a little bit round the centre of a circle that lower part raises a canal to go up connect a line) included angle. (3) prejudicial A: Be in charge of axes and the vertical distance between the axes that raise a canal, have the cent that losing, when should be in charge of axes to stand by handlers prejudicial for, when should be in charge of axes to be far from handlers prejudicial to lose. (4) works dot uncle moves (wrong heart) E: Point to for many times build each director axes and photograph of the axes that raise a canal are nodical when receiving (node) distance, angle of cut of the axis between component part, turn round horn, prejudicial, job to nod deflection (wrong heart) computation is the method that uses analytic geometry, model of work out maths, be calculated through the program and get a result. Between pipe fitting of in an attempt to turn round horn to be exemple, show the program numeration of geometrical parameter. Between two canals turn round horn to be 0 degrees. If have the 3rd canal, exist 2 times to build namely receive, director 2 if be absent,be in charge of 1 as planar as what raise a canal to form inside, exist reverse part. This angle is the director that measures in the transverse plane that raise a canal 1 at be in charge of 2 umbriferous angle of cut. The move of programming is as follows: (1) extraction is in charge of Plll of 1 two end points, p121. (2) extraction raises a canal P12 of two end points, p22, computation raises arrow tubal a way (M2, n2, p2) . (3) is called seek umbriferous drop order, beg Pl1l, p121 is raising the umbriferous Md1a on tubal end panel, md1b. (4) use AutoCad commands (Command " Ucs " " N " " Za " P22 P12) turns tectonic plane to the end panel that raise a canal. (5) uses function (Trans Md1a 0 1) , (Trans Md1b 0 1) , computational Md1a, md1b is in the coordinate Md1aa on new tectonic plane, md1bb. (6) function (Angle Md1aa Md1bb) seeks a person in charge 1 photograph to securing F11 of reference axis angle. (7) commands (Command " Ucs " " W " ) changeover is fastened for world coordinate. (The measure on 8) in order to seeks a person in charge 2 opposite at securing FlZ of reference axis angle. (One Fll of 9) Fl Z gives priority to a canal namely 1 with the director the 2 included angle on the transverse plane that raise a canal, reverse part namely. 5, line of computational look follow in a continuous line makes sheet the type of common line of look follow in a continuous line between component of platform of graph module ocean has a canal to provide the saddle opening between, the diameter provides opening of the MIT between the canal identically, mouth of the MIT between tube plate, and line of follow in a continuous line of Taper Pipe look, annulus provides clue of look follow in a continuous line, line of follow in a continuous line of footmark graph look is waited a moment. The system is automatic the type of line of differentiate look follow in a continuous line, namely handlers is clicked after be in charge of and raising a canal, the component part information that the program can input before the basis judges the kind that gives clue of look follow in a continuous line, call corresponding subprogram to calculate thereby line of look follow in a continuous line. The program block diagram that judges type of line of look follow in a continuous line shows 4 times like the graph: The lever that program basis stores the type can be called automatically seek order of line of look follow in a continuous line accordingly, the structure that makes this valve thereby is simple a graph. Below it is in order to raise canal and form of director look follow in a continuous line exemple, give out raise a canal to seek solution sheet the end product of the graph. If pursue 5, each parameter is as follows: Raise a canal: External diameter is 318.

75mm. The wall is large for 9.

375mm. Director: External diameter is 450mm. Work out program, get 5 show a canal to cut sheet of the analyse inside exemple hind is like a graph graph, there is wall look in the graph line of be linked together and outside the wall cuts secant actually (take groove horn) namely, its abscissa is Y axis, namely shift of axis of Y of cutting torch edge is apart from, ordinate is corresponding the circumferential horn that goes up each a little bit at line of look follow in a continuous line namely X axis coordinate. 6, conclusion system serves child blaze numerical control cuts tubal machine cut maritime platform conduit wears pipe fitting, systematic input makes the same score the structural single track that combine to pursue for ocean, systematic input wears cut sheet for maritime platform conduit graph. Build a program to store conduit wears the graphical dictionary of information of component part geometry automatically, thereby lever information memory, and can want according to abide call at any time, revise. In addition, use the method of analytic geometry, model of work out maths, establish a program parameter of automatic computation geometry, angle of cut of the axis between implementation component, turn round horn, prejudicial, job to nod deflection (wrong heart) automatic computation. Snap the type of line of look follow in a continuous line through process designing chaste tree, automatic computation raises data of line of tubal look follow in a continuous line, scale gives conduit to wear sheet graph. The system enters the writing of component part parameter, computation and processing join rise, via actual project application, the automation that implemented pipe fitting treatment, intelligence is changed, improved manufacturing efficiency greatly, it is a kind of application of CAD/CAM unifinication technology.
