But a few new high end software, if data of three-dimensional CAD software, product manages natural resources of software, company,plan a system introduce and apply, make be able to go to of software system compositive degree of requirement that cannot satisfy an enterprise to develop currently with compositive platform, produced the software system of new information Gu island and disperse thereby, the progress that gives an enterprise future brought new issue. The research purpose of this task is aimed at workshop of aviation numerical control to be opposite namely the applied demand of production engineering software, with spare parts of aviation numerical control production process is an object, it is harmonious basis with three-dimensional number prototype, the digitlization of current and will dispersive, independence and Gu island type makes software undertake applied compositive, build workshop of aviation numerical control to digitlize system of production application software, the number in satisfying spare parts of plane numerical control to make a process at the same time measures harmonious working system, preliminary those who form numerical control of industry of contented and contemporary aviation to produce production flow is compositive change work in coordination environment. Its achievement can serve as support ongoing the digitlization that reachs development of prospective aviation product and production is compositive working platform, the production system that is based on network and digitlization environment to will be built henceforth provides the platform that prop up, the production process that is implementation aviation product and production system is compositive lay a foundation. Site of production of workshop of numerical control of architecture of production software of digitlization of numerical control workshop and manufacturing process are unusually complex, involve " person " , " machine " , " makings " , " law " , " annulus " wait for numerous information, relevant information system is distributed in the plan, carry out, the many levels such as control, on the base that adopts survey of pair of workshop of aviation numerical control, analysis and Baconian summary, put forward workshop of aviation numerical control to digitlize production software architecture, if pursue,1 is shown. This system includes 8 subsystem, among them core system 5, it is system of preparation of system of system of production resource coding, production resource management, production data, workshop respectively plan management system and system of manufacturing site management; Support system 3, it is preparation of systematic foundation platform, production respectively moving system and spot control collect a system. Systematic foundation platform regards the application of whole and compositive system as the portal, the centralized management that will realize each subsystem and only place login. The user does not need the applied system with numerous reentrance when getting specific information, go to the lavatory to get quickly through the portal however. Additional, in systematic foundation platform, decide every user can apply what subsystem only, the functional attributive of subsystem interior and data attributive distributing to be defined in each subsystem. Production resource codes the system is the foundation of architecture, for other each systems offer exclusive production resource encode, finish what code to making resource to build through this system, examine and approve the management that reachs modificatory process. Offer encode application and encode to retrieve a service for other subsystem through systematic interface at the same time. Production resource manages a system to unite management and digitlization to make relevant objective news. Production resource includes equipment, cutting tool, measure, clamping apparatus, mould, other tool and material to wait. Production resource manages what systematic management company makes resource to form (make / purchase / other) , label, store, use flow of the implementation means that waits for the job, work and flow control pattern, can divide commonly for 5 module, it is handling of goods, cutting tool management, clamping apparatus management, equipment management and measure management respectively. Production data prepares a system to unite management and digitlization to make relevant all data news, basically be the compositive application of CAD/CAM/CAPP system and PDM system. Among them product structure safeguards module to provide product structure information and 3D model for CAPP system, module of library of technology natural resources offers production resource parameter and resource encode, technology knowledge base and cutting parameter library offer technology knowledge and cutting parameter respectively, make craft news finally, include summary table of program of norm of craft course, material, procedure, test gauge Cheng, NC, production resource to wait. The function such as design of the plan that hold card, tool design, emulation desired result and printout still is provided in this module commonly. The workshop plans to manage a system to receive an enterprise to produce a plan, to producing the job first, the system will submit task information to production data to plan a system, the craft that finish prepares; To for many times task of put into production, generate a workshop to produce plan and stock demand plan according to the information such as norm of product structure, material, procedure. Producing spot management system is the main software system that produces process government in the light of numerical control workshop. Produce information of staff of plan, on guard, craft information and information of production resources stock to wait according to the workshop, undertake the task the platoon is produced and attemper automatically, make list of workshop exercise task. Through executing AO/FO management, record and monitoring workshop make the executive case of job job, plan feedback of manufacturing statistic information to run a system to the workshop. Still include the function such as quality management and equipment efficiency evaluation in producing spot management system. Producing preparation to run a system is the interface between workshop executive layer and control layer, the NC program list that the need in producing a course certainly according to exercise task uploads and the list of specific production resource that deserve to send, the machine tool with affirmatory NC deferent at the same time file and transfer time and stock deserve to send time and target work. Spot control collects a system to basically be used at controlling stock to deserve automatically to send file of system, NC to deliver to mix of automation knife library move, at the same time can network DNC system obtains a machine tool to process data in real time, regard machine tool efficiency as the foundation of evaluation its. Digitlization of workshop of compositive numerical control makes system of production software of digitlization of numerical control workshop case of set prescription of software system collect is to be based on " digitlization of numerical control workshop creates software architecture " and make, among them, system of system of coding of systematic foundation platform, production resource, production resource management and system of production data preparation are the foundation with compositive system, information of the member that become the holder that in can assuring to plan manage site of system, production to manage system, production to run preparative system and spot control to collect a system in the workshop, moves, data information and objective information have these 4 tight market of the system only label and onefold, assure consistency of data. What control of system of system of workshop plan management, manufacturing site management, spot collects a system is compositive it is a workshop plan layer arrives again to executive layer those who control a layer is compositive, producing moving preparation system is workshop executive layer the compositive adapter that controls a layer to the workshop and participate in interface artificially. The compositive program that the article will plan system and system of manufacturing site management to introduce a system for the center with making data. Compositive technology is making system of preparation of Nextpage1 production data in planning a system, data builds production BOM data, and be aimed at modificatory circumstance establish modificatory information, the workshop plans to manage systematic basis to make pool of BOM and modificatory information, form newest production BOM data; Pair of spare partses are united to undertake technical data and craft change management in production BOM, include ration of detailed procedure, material among them, carry early days and relevant tool, tool, complementary makings to wait for list information, these information are a workshop the basis that plan management system builds a workshop to produce plan and stock demand plan, also be to produce spot management system to do a platoon to produce attemper and the basis that start working checks. So, system of production data preparation is to be a workshop to plan what spot management system provides fundamental data to supervise system and production " data base " , the workshop production that the specific production in producing spot management system at the same time organizes a course or with the workshop plan management system makes plans to serve as main basis. Accordingly, from the point of iformation flow, production data prepares a system to plan to manage systematic advanced position in the workshop, and those who produce spot management system to plan to run a system in the workshop is downstream, so, these systems and the data set that the workshop plans to run a system generalize into OK and simple ground for: System of production data preparation plans to manage system and manufacturing site to manage a system to transmit production data to the workshop, be relatively one-way compositive; System of workshop plan management manages a system to pass manufacturing plan and stock demand information to manufacturing site, system of manufacturing site management plans to manage systematic feedback to plan to carry out a circumstance to the workshop, be two-way compositive, the main message with this compositive part is compositive platform is system of workshop plan management. Graph case of set prescription of market of production software of digitlization of workshop of 2 numerical control is additional, the effect that the project change of production data plans to downstream workshop and produces a course is the discussion focus with this compositive part, the plan that article setting task adopts is: The make known to lower levels of plan of plan of the production in system of system of workshop plan management, manufacturing site management, form a complete set, process work plan, use newest BOM and technical data, if during in planning a system, production data produces production BOM change, in system of plan management system, manufacturing site management already the information such as the plan of make known to lower levels, inventory all changeless, systematic general undertakes reflecting in follow-up plan. This kind of compositive means, can assure to produce the stability of the process already, also accord with war industry to produce the main demand to model, batch at the same time. The system is overall and compositive train of thought. Compositive technology produces system of management of 2 production site spot management system attempers after the result course that the platoon produces affirms, can form the exercise task list of directive and actual production. Production prepares to run a system to carry list of task of all previous exercise, the NC Cheng alignment related the order that receives needing to upload to machine equipment individually is expressed, and need deserves to send each work the production resource list such as semifinished product, tool, clamping apparatus, measure. In process of list of affirmatory NC program, alignment of Cheng of NC of systematic general scanning is expressed, get machining the cutting tool list of process place need, unified and will affirmatory cutting tool mixes system of manufacturing moving preparation of other production natural resources deserve to send time and target work. In cutting tool list and semifinished product list, make the parameter news of resource only commonly, still cannot affirm the specific production resource that deserves to send is individual completely, general need personnel intervenes, undertake affirming finally in the optional resource that numerous system recommends. The NC order order that production plans to run a system to will need to upload to machine equipment individually is expressed and make resource through what affirm deserve to send detailed list to send spot control to collect a system. Spot control collects a system to will receive these information, transmit those who reach stock to deserve automatically to send a system to move through what DNC module controls NC process. In addition, spot control collects a system to still will collect information of manufacturing spot position to feedback to produce spot management system, regard the foundation of manufacturing statistic and equipment efficiency evaluation as data, graph 3 it is compositive sketch map. What article setting task uses is to be based on embedded network DNC system of the system, with unitary network DNC system server and what can embed the spot makes equipment directly is embedded the treatment workstation that systematic module replaced spot of numerous cent park, the network scene that made clarity of circuitry of structural forthright ﹑ makes a system. All equipment include the site numerical control machine tool, deserve to send a car to wait, unified allocation IP address, the network resource that serves as a standard undertakes administrative, what realized production successfully to prepare to run system and spot control to collect a system is close together and compositive. Branch of spot position information is 2 kinds, a kind as close together as equipment relevant, can collect automatically through DNC system, wait like information of equipment switch machine, breakdown information; Additionally one kind of need passes other information system or data terminal manual input, include to making information of spare parts information, on guard staff and time of personnel mount guard wait. Setting task uses be based on embedded the spot information of network DNC system of the system collects construction of system, wait for technics through using card of card of bar code, IC, magnetic card, RF-IC will embedded system and information collect a technology successful confluence. Graph the information of Nextpage of overall and compositive train of thought of system of management of production of system of management of 4 workshops plan and system of production data preparation, spot the system is compositive technology and method the advance rapidly as software technology, compositive technology also got the system develop lickety-split, in data layer, application layer, express layer of layer kimono Wu to wait to a large number of technologies can offer an alternative, compositive mode also arrives a bit bit of system company application is compositive, compositive (Enterprise Application Integration, EAI) wait, be based on of late face service framework (Service Oriented Architecture, abbreviation SOA) the system is compositive mode, also got paying close attention to with all possible means. Below introduces a few kinds to make the software that compositive middling sees software system in digitlization respectively compositive technology. (1) the compositive technology that faces a database to visit a layer. Database visit layer is compositive it is the compositive method that the layer visits to undertake data is exchanged in the database between 2 systems. Stability of function of this method interface, data exchanges real time sex strong, can cross the characteristic such as systematic platform, apply to switch of tiring-room batch data. As the ceaseless development of database technology, the measure that the data of database visit layer exchanges is increasingly substantial also, the data between the different ground database that can realize platform of different operating system to fall at present real time exchange visits or the fixed data synchronism that are based on job plan. It is OK also to cooperate to use memory process and XML technology at the same time the data between database of implementation different compose is delivered. Although the database visits the law of data set set prescription of the layer, no matter in stability index, system real time sex is reached cross platform to visit ability respect to all have good performance, but because finish a database to visit the data set of the layer to become need interface to develop personnel,be opposite bilateral system and structure of interface share data have thorough knowledge, have certain limitation in specific project executive process so. (2) the compositive technology that faces applied layer method to call. Compositive technology basically reflects this system to be developed 2 times in large trade system, these systems can provide a system compositive development kit, in passing pair of kit, offer kind with function call, can visit systematic data and business flow. These compositive development kit, general meeting is based on some kind of mainstream among technical platform gives out, the CORBA of the DNA 2000 of the J2EE that basically has Sun, Microsoft, OMG. But the develops kit function that compositive deepness and range get a manufacturer to offer opens degree limitation. (3) the compositive technology that faces a page to express a layer. The range of compositive means application that faces a page to express a layer is narrower, basically use in B/S construction of system, wait for compositive system to be able to offer a compositive port commonly, the functional name that wants compositive both sides to offer only and page address accord with specific regulation, with respect to the mutual visit that can realize a page. This kind of compositive means can have a function only medley, cannot have depth commonly compositive. The difficulty of this kind of compositive means is the control that attributive visits after the system is compositive. (4) the compositive technology that is based on Web Service service. Web Services is in Internet aspirant travel distributed calculative constructs basically piece. The communication agreement between open standard and user and applied process produced a kind of new environment, below this kind of environment, web Services becomes the platform with compositive application. Applied process serves construction through using the Web of many different origin and become, no matter these serve after all to be located in where how to perhaps come true, they can work in coordination each other. Web Service has the following profit: · supports a variety of development environments and development language, make undertake corresponding becoming a possibility between different development language; · supports HTTP agreement, can cross region firewall, implementation is remote transmit and correspond; · support can search a gender, can UDDI service undertakes retrieval to Web Service; · is had depict a sex oneself, the interface between much system needs to offer an interface to be able to come true only; The Web Service each other with many · is alternant, can come true through a representative among, this representative is called Web Service Proxy Bus (bus line of information of Web service representative) , of all Web Service call undertake through this information bus line. (5) the compositive technology that is based on Portal platform. Portal is in recent years a of IT domain vital new technology, it helps an user do not need the applied system with numerous reentrance when getting specific information, go to the lavatory to get quickly through the portal however. Portal itself already webpage of by static state, content company operation platform, application is compositive, compositive the Portal that development perfects to today. Portal as information compositive platform realizes the conformity that business information applies, compositive, rise in value, had become business information to use compositive main base frame. Portal technology applies compositive, structuralization compositively, remotely to data set is become and was not face of set prescription of structured data set to offer very overall technology support and solution in the light of this locality application. (6) the compositive technology that is based on SOA framework. Face service framework (Service Oriented Architecture, SOA) it is distributed calculative a kind of mode. Below this kind of mode, software function develops the form that is a service on the network, these services can distributing to be nodded physically at what differ, can each other discover, call each other, the coupling between them is inattentive, it is agile, can the metabolic reset according to demand for service. These SOA characteristics make its are applying face of systematic collect set prescription to be paid close attention to extensively. Apply SOA framework, below OK and compositive different operating system, of different data origin, different language develops, the information system that is based on different frame. SOA pays close attention to information exchange and flow butt joint not only, pay close attention to systematic flow further optimize, share in the service, systematic safety and system expand the respect provided powerful support. But the compositive system traversal speed that is based on SOA is slow, systematic expense is big, need invests many hardware resource, and the form that develops platform builds the system to also need to invest a large number of capital. The last word involves the compositive information system of mass data and flow to, systematic stability and data security are the issue that need chooses in the technology and the consideration emphasizes in systematic design process. The function of compositive information system and using a sex easily is a system whether a when carry out smoothly main factor. Below the condition that the condition allows, still should throw proper time to undertake Training Within Industry, this has very important sense to promotion application of the system. CNC Milling
