Since digitlization makes a technology arise oneself, had gone up from the technology " only place tool " moved toward collect engineering technology and craft manage the comprehensive solution at a suit. In last few years, digitlization production companion manages as production process (Manufacturing Process Management, MPM) the concept blends in product lifecycle to manage (PLM) platform. In the digitlization of technology program, component the digitlization of treatment, product is assembled beforehand, the applied domain such as man-machine engineering analysis, below the support of PLM platform, of the data that implemented whole group and resource share, those who rose to make organization and enterprise inside and outside is effective cooperate with, advanced the intellectual put sb in a very important position of the enterprise. The safeguard with the validder function such as the modificatory management of PLM, version management digitlizes production correct seed to apply. Digitlize the tentative idea that production development course digitlizes to making a process, the earliest can restrospect to 20 centuries 50 time, the researcher tentative idea of American Masschusetts Institute of Technology undertakes operating to spare parts model on screen, in the meantime, according to the model on screen, the spare parts is machined on the machine tool. This is in at that time just is a kind of ideal. After this, the occurrence effectively of numerical control technology and numerical control machine tool supported this tentative idea, make the treatment process that controls component with digital amount becomes a possibility. Inchoate numerical control machine tool already giant costly, applied scope is very little. In time of a few years of later, computer technology develops quickly, operation speed is accelerated, memory capacity is increased, bulk is ceaseless and contractible, this controlled systematic development to produce huge to promote to numerical control machine tool. Meanwhile, the development of CAD, CAM and CAPP technology, drove the progress that digitlization makes directly. 20 centuries since 80 time, the country such as Israel began the research that systematic digitlization makes and application early or late. Above all, 1985 around began a robot kinematic emulation research, apply at the process designing leaving a line of the robot. This product line to using a robot, especially auto industry, have important sense. It shortened greatly of product line debug, manufacturing preparation is periodic, raised the rate of city of new product range. From a few production systematic emulation is optimized, the automation that produces unit considers to begin, about " digitlization " production concept and practice from a few " dot tool " develop gradually rise, push step by step to each respects of production project, formed the computer to assist manufacturing engineering (CAPE) concept. 1996 around, production process digitlization begins to build development of frame of whole production process to compose, craft model is built on production server, product and manufacturing data implementation are shared, individually " dot tool " the professional module of the type is not had seam the ground compositive together, support each link of whole process, include: Manufacturing plan formulate, product line is defined and norm of balance, man-hour, spare parts is machined and numerical control process designing, rig a process file of guidance of layout of effect of control of research, quality, man-machine, workshop, job, craft is generated etc, formed a function all ready, move on the computer " digital chemical plant (Digital Factory) " . Here, emulate be applied widely as main technical measure. The fictitious production environment of high-powered computer and network support is " digital chemical plant " the base that run. The crucial link of production process and essential feature are shown at actual process of physics first come out, what the problem that manufacturing process may appear also is planning is inchoate by discovery, get early settlement thereby. At the beginning of 2000, israel Tecnomatix company offerred the concept of MPM on company annual meeting, support makes process lifecycle, arrive from technology of process program, workmanship and equipment namely the process of finished product, will whole all members of production catenary include connection of manufactory of engineer of OEM stylist, craft, equipment and stock supplier to arrive in a dummy company. MPM conduces to manufacturer forming first-rate to produce strategy in order to support commercial strategy, its executive result drove digitlization to make further develop to all-around solution. Nearly two years, PLM becomes the digitlization platform of the unified framework of a lot of production enterprises with each passing day, MPM has become PLM platform impartible cut one share. Digitlization is made share unified environment with product research and development, while sufficient play engineering technology emulates an advantage, promoted the capability that goes up in production data management, process management and resource management in the round again. Digitlization makes a process make a process, arrive from the program carry out, the activity that involves all sorts of complex and mutual connection -- be machined from the spare parts and assemble craft to plan to project of position of unit of plant design, job, man-machine is analysed and pledge gauge delimits. The digitlization that is based on PLM makes a solution can support and simplify all these activities, shorten the job is periodic, improvement cooperates with and advance the put sb in a very important position in the knowledge in whole production process and resource. Production process is OK and abstract for the flow model that by product, technological process and resource 3 element comprise one. Among them, the product is a general designation of semifinished product, raw material, semi-manufactured goods, spare parts, component and end item. Technological process is the gather of the whole process of production product, include to machine, assemble wait for link. Resource, broad sense ground includes the tooling such as personnel, factory, tool and clamping apparatus, it is the requirement that technological process is able to have. As production process undertake, through a line working procedure, product configuration changes to the end item of can contented use requirement by original raw material, semifinished product gradually. A complete product, often by a certain number of component and spare parts composition, every component is comprised by a certain number of stature components or spare parts. Below PLM environment, all 0, the component is by configuration of logical arrangement of ideas on product tree. The many product information that comes from CAD includes a variety of forms: The text file of condition of technology of the digital-to-analogue that describes component geometry figure and blueprint, account and standard, relevant animation or file of movie and TV compositive cultivate in product structure in. When applying actually, express the different version of similar product even. Process includes much talk process. Working procedure information includes personnel of content of working procedure name, operation, man-hour, operation, place to need equipment and cutting tool tool to wait. A working procedure can be divided into a certain number of labor situations to carry out. When design and establishing technological process, according to the appearance of specific component, function, craft asks, integrate principle of division of labor of plant construction, workshop, the working procedure with formulate craft course, logical choice and labor situation, allocate proper job is unit and assign place needs tooling, appoint place to need to handle staff technology social estate. The design process of the technological process below PLM platform, also be by the BOM of design stock detailed account, procedure that establishs production BOM. BOM information and production process detailed list (BOP) relevant couplet, ensure proper product configuration is used in proper context work environment. Resource information comes from the factory is designed and be versed in clamping apparatus of a layout platform, tool designs many channel such as platform. Below PLM environment, have classified government to a variety of production resource, the typical craft that succeeds according to the enterprise and the stencil that production experience forms, those who assure pair of resource and factory layout is reasonable use. The use effectiveness below PLM environment manages, can differ according to the different situation of the sale and product the change of batch technology condition, provide accurate information, have effective modificatory government, the validity that makes sure the product digitlizes production process and the quick response that change to the project inside limits of product complete lifecycle. PLM is strategy of production enterprise informatization, also be the platform of executive informatization. The mechanism of informatization of this kind of production process cooperates with those who make sure production group is more significant, make working group is in when needing, visit crucial data quickly, realize what industry pattern craft reachs production experience to share, achieve the knowledge engineering of the enterprise and intellectual administration. Nextpage craft plans to reach its to emulate lifecycle of product of test and verify to manage (PLM) when the production in program product, operation of the production resource that wants real product data, place, working procedure and production feature connection rise establish complete process information, formed the technology program that states clarity, it is the main thread that digitlization makes whole process, it makes all craft information can be in enterprise interior and whole industry to supply chain all relevant personnel implementation in each link are shared highly. On the technology program interface of digitlization, realized a product three-dimensional show, can undertake shrinking putting, rotate operation, planned dispatching personnel is OK and clear the observes a product condition of the ground changes. It is clear that the name of the executive order of working procedure, each working procedure needs time and resource to wait for a form with all sorts of forms, chart and character with executive content, place the ground expresses. Program of technology of have the aid of can quantify the ground to make yield analysis, norm allocates and can be versed in a layout design. Pert graph contacts spare parts, production feature and resource and operation. In the meantime, it can define the stock between each working procedure to flow, make stock plan then. The function that Gantt of have the aid of pursues, intervene in what plan personnel balances of next tone entire product line and the crucial way that identify product line to go up. In the meantime, craft plans to meet whether does attention of caution plan personnel exist potential resource uses conflict. Preliminary the technology program that establish, OK still incident of disperse of have the aid of emulates a function, undertake the function of product line is analysed, include size of balance of crop, stock shedding, bear, bottleneck and buffer to wait, the test and verify that implements a plan and optimize. Undertake emulation an analysis to disperse incident system, want commonly to build emulation model of the system, according to the type of workstation and operation, choose proper distributinging function and control strategy to describe a system. When emulation model is built below PLM environment, a lot of information that craft plans can come from PLM system, software finishs information automatically to deliver, the operation is convenient. Enough to emulating a model to undertake after moving for long, the system gives out the function index value that the expression after this plan plan is moving continuously comes out, like productivity, metre, efficiency, wait in goods, inventory, express with the form such as chart, report. When scale of production when bigger, system is more complex, the model that has emulation an analysis can use the structure that administrative levels changes, express the administrative levels such as product line of factory, workshop, workshop section, team and group respectively, make of the model state very clear, look be clear at a glance. Factory, workshop, workshop section is different personnel of the production of level, plan is OK with respect to oneself duty limits undertakes more thorough analysis studies, master overall situation and local concern, undertake be adjustmented appropriately when necessary. Should emulate built a model to consider interior is mixed exterior when supplying resource of catenary, production and business affairs process, can analyse production to change the influence that brings to swimming up and down, evaluate diverse product line to control politic actor bad, the synchronous circumstance of product line of test and verify and sub product line. The likelihood in some of product line moves exists " bottleneck " , it limitted the moving efficiency of whole system, become raise high yield can crucial. To such problem, manufacturing branch can offer a variety of improvement way, these method often are pair of original plan is local edit. Through the emulation of plan moves and undertaking quantitative analysis to editing, can give out final improvement method. When some industries are undertaking design and be optimizinged to producing a system, consider content shedding increasingly inside, the strike that spreads to content, density, carriage means undertakes emulation an analysis, sort thing visible, with Sankey the graph shows the stock below current configuration transmits a quantity OK and intuitionisticly. A lot of emulation tools use genetic algorithm in producing system simulation, can according to all sorts of tie conditions (if crop, inventory, resource is used,wait with due date) will optimize systematic parameter, make the system is achieved overall optimized target. Component digitlizes treatment to be on PLM platform, administrator of personnel of products plan personnel, process designing of technologist, numerical control, tool design personnel, planned dispatching personnel, production shares stock detailed list (EBOM) products plan data of the form and electronic craft sheet (EBOP) production project data of the form, when they are executing respective mission, correct component can be visited to make data in right time, implemented each departments between collateral work in coordination. Such, shortened already the project is periodic, rose to produce the project quality of the process again. Platform of PLM of have the aid of of engineering technology personnel, all sorts of information of the component that can obtain design branch to offer conveniently (condition of model of exactly the amount, blueprint, technology) , have comprehensive knowledge to the product. Devise the treatment method of the spare parts accordingly, the work out gives procedure. The model that CAD system builds, it is the basis of program of work out CNC Machining. By the resource information that PLM platform provides, obtain the safeguard condition that treatment requires, measure of axis of the configuration that is like numerical control machine tool, drive, journey, knife, clamping apparatus, program of work out numerical control, undertake postposition is handled, the staff is other craft file. The distributed numerical control that these files will transfer a workshop (DNC) system and make executive system (MES) , the basis that the working directive document that handles as directive worker and manufacturing plan personnel weave exercise plans. No less, in digitlizing treatment, emulation technology also is very important. What want normally basically is numerical control cutting is emulated and cutting parameter is emulated optimize. The numerical control program of initial authorized strength is trying before cutting test and verify, often can have a few neglect or flaw, need test and verify and perfect. Emulation tool of numerical control cutting shows the purify process of the opposite motion of cutting tool and workpiece and material according to file of cutting tool position, detect whether to have interference and " cut too " phenomenal happening. Cutting process interferes an examination, not only need detects the interference of cutting tool and workpiece, consider machine tool main shaft and clamping apparatus to wait even between whether can produce interference, collision, so that ensure treatment is safe, no risk at all. No matter be machine tool of costly much axis numerical control, still be form is complex, the spare parts with treatment very long cycle, collision and interference are absolutely unallowed. And to interference forecast, be opposite especially 5 coordinate CNC Machining, sheet leans cannot come true artificially. On the other hand, all sorts of professional emulation software serve as " dot tool " the auxiliary effect with also was certain treatment method and program of work out numerical control to offer main. With treatment emulation software imitate machines the mechanism of the process, the physics in analysing a process changes, the formation that bits cuts in be like process, the temperature of the cutting tool when treatment and material distributings, the change of cutting force, those who understand these meetings to conduce to cooling condition is affirmatory wait for those who machine parameter to optimize with rate of revolution, feed, it is the content with the numerical control indispensable course with reasonable work out. Software of this kind of tool, besides treatment parameter is emulated, still have cast a process to emulate, solder the process is emulated etc. Nextpage digitlization assembles design personnel to be able to be in of product research and development inchoate, the primitive data that uses CAD system is tectonic and fictitious prototype, analytic product the position of each component affects, mutual the distance between and cooperate, detect of tolerancepublic errand maladjusted. Digitlization is assembled beforehand (Digital Pre-Assembly, DPA) the dynamic process that product of technical with a view to rigs, the assembly that designs product component is ordinal, pursue with Gantt and adjust assemble order. Build the way that assemble and decomposes, can emulate component to sweep the space that flit to include sth resembling a net in rigging a process, so that have interference examination. Once have interference happening, want phonate sound or color hint. Can use sometimes a series of show detailed interference process sectional and dynamicly, represent the range of an interference. From the point of view that produces a project, digitlization assembles what more research assembles to carry out a process beforehand, assemble a process to be put in project environment (include workshop, personnel, tool, tool to wait) below, unit of the workshop environment in rigging a process to the product, job, content shedding deserves to send attitude of method, product to undertake emulation, analysis and editor, approach a project adequately actual. Digitlization assembles research beforehand not only apply to rig a process, also apply to tear open Jie Hewei to build a course. The digitlization below PLM support assembles a technology to have the following characteristic: Shorten the research and development of new product is periodic; Inchoate discovery problem, reduce design mistake; Examine with fictitious prototype design program, reduce development risk; Assure to use correct version; The response that changes to the project rate is rapid; Solve potential problem below fictitious environment, shorten time of products introducing to the market. Man-machine engineering analysis is assembling production in exercise, the importance that the member that consider yard place and manufacturing process go-between behaves is outstanding with each passing day, workers are in safer, more when the product is being made in the environment that accords with human engineering, the enterprise can improve product quality greatly, improve exercise efficiency. Man-machine project copy can tell what to the worker can see engineers and capture really, work environment is friendly, workers are in what place to be harmed likely, whether can feel " ability not equal to one's ambition " or a few important man-machine project information such as exhaustion. Those who be based on international standard, the mannequin library of different sexual distinction and figure, can ensure be versed in a worker that the design suits type of each ethnic group. The user can be versed in to the person exercise undertakes detailed, accurate with effective design. Mix through different grab walk grand command, define human body movement OK and conveniently. (1) emulate artificially. The best operation that affirmatory product is assembled and disassembles is ordinal, carry dynamic chart and time order, can know constructional feasibility and limitation, decide optimal operation is ordinal thereby. (2) the detailed design of manual operation. In fictitious 3D environment, discover the collision between human body and environment, analyse the working limits of personnel, ensure the arm of the feasibility of artificial exercise, person can achieve gender and the window that pass agile configuration to show worker field of vision, complete exercise feasibility inspection from the worker's perspective, reasonable design and optimize manual operation. (3) ergonomics analysis. Restrain artificial operation according to the standard of ergonomics. Through making servantchoose a person for a job mechanic Cheng learns standard method (like NIOSH 81 and NIOSH 91) , mix to snatch carry exercise to have effective examination, analysis, consideration is the biggest accept power, OWAS (Ovako job attitude analyses a system) the method can undertake attitude is analysed working. (4) time study. The accepted primitive data that MTM of have the aid of publishs expresses the executive time of OK and affirmatory artificial operation. The user can arrange project afresh through man-hour and ergonomics analysis, make an operation more comfortable, more efficient. Besides assembling an operation, man-machine project copy also is really in processes of a variety of research and development receive wide application. Advanced virtual reality system can provide a fictitious sensory space, the user ases if place oneself among them. Cooperate to use glove of tracker of helmet type monitor, position, data to wait for input equipment, participator produces a kind of be personally on the scene, total heart to throw, be enmeshed among them feeling. What personnel of research and development is developing is inchoate, can obtain at real product first be enmeshed completely (the experience of Immersive) . Of personnel of the function test and verify that waits for a product to resembling tank, plane, naval ships, operation groom and the it is main to suit to be had effect of battlefield environment. Man-machine project copy often is to be used at first really solve such as to be able to achieve gender, attitude, carry those who lift force, metre to wait for ability of human body nature to evaluate an issue, establishing operation guideline, norm of work out man-hour, the respect such as code of comply with labor insurance provides a help. The development of the near future makes he entered wider application. In the research and development of a few complex products, in the development appraisal of major project, handlers individual or group by park in large setting and complex environment, they finish the whole unit process of cargo bandling of a series of sophisticated acts harmoniously each other. For example on the military affairs, of engine of imitate carrier-borne aircraft tear open solution, maintenance, in installing a process again, below the limitation of complex inside the narrow space on naval vessel and storehouse environment, maintenance group should be in fight below the condition, finish complex working technological process as soon as possible to achieve strict quality requirement. The last word transforms traditional industry with IT, drive industrialization with informatization, implementation spans type develops, oneself the national policy that makes us. More and more production enterprises consider from the strategy of long-term development, elaborate program and active compose build business information system compositive frame, share to deepen business information, drive enterprise innovation found. Traditional production industry, equip especially manufacturing industry, the digitlization below PLM strategy support creates platform, will add new vitality to enterprise innovation.
