Digitlize the program of the factory

General assembly workshop is to the product line of demand general assembly of digitlization by the organic whole that carries equipment and special device to form, advanced assembly the tooling with craft advanced need, the high quality that tooling designs the production with production efficient to assuring level and product is crucial, also be the mark that the car assembles technical level. Regard a car as the last link of 4 old technology, general assembly workshop can feedback directly the problem that place of before going out 3 link exists, and car product is at present more and more complex, not only the appearance of the spare parts is diversiform, and the part that includes in the product number is very much, the assembly between the spare parts concerns complex, and manufacturing facilities increasingly incline to is complex and costly, whether do the layout of equipment of general assembly workshop and configuration suit have and later period product, will affect company profit directly. To shorten the production of general assembly workshop makes preparative time, improve the efficiency that craft of general assembly workshop plans and quality, the production that discover as early as possible and reduces general assembly makes medium mistake, accelerate new model to appear on the market, applying digitlization to make a technology is best solution. 2.

Tecnomatix digitlizes compose to build (1) the compose of resource library builds what study normally to make disperse of systematic dispute linear change a system, need builds product model, resource model (staff of clamping apparatus of production equipment, raw material, the sources of energy, labour, production and production environment) , craft model (craft regulation, production course) and manufacturing management model (systematic limitation and tie concern) . Digital chemical plant is to build what go up in model foundation to optimize emulation system, so digitlization builds the base that modular technology is digital chemical plant, only all ready and accurate model ability assures to digitlize the integrality of the factory and accuracy, this shows model of early days resource building is indispensable. Resource but the classification of means proper motion according to him company, this A1 project is resource cent kinds Equipment, Human Models, Logistic, Tool, Transportation, Layout and Other6 are big, the digital-to-analogue resource (Co or Cojt file) in the folder that in putting SysrootLIBResource, classifies each can, if pursue,1 is shown. Graph 1 resource library (2) the BOM list that the compose of product tree and product library builds a basis to design a branch to offer inputs Tecnomatix according to certain hierarchy in, product library medium spare parts procrastinates move corresponding product tree to go up can, according to the particular case of much model, spare parts amount does not show on product tree, show in follow-up operation tree, if pursue,2 are shown. Graph 2 products tree and product library 3.

The craft characteristic that the compose of craft line builds general assembly workshop is much model / the component that configures the production that confuse a line, need to assemble more is very much and operation of major humanness labour. Be aimed at characteristic of craft of workshop of general assembly of class A car, we put the emphasis in assemble ordinal, resource and layout to optimize, product line balance and man-machine project are emulated on, specific technological process is shown 3 times like the graph. Graph Nextpage of 3 technological process (1) craft definition chooses BOM to express medium component, component preliminary allocation go to each workshop section, the assembly that edits a component craft card, through craft card can deepen understanding to rig a process further. Edit craft general situation to express according to craft card, it is OK and preliminary make piece assemble order. Specific and OK use PERT graph to define each working procedure intuitionisticly between order (see a picture 4) . Graph 4PERT pursues (2) after allocating component to be defined in craft, the outfit recipe law of component and assemble order effect has seen first, undertake for more intuitionistic below 3D program environment ground product structure is analysed, pull product tree now in dragging craft to cultivate, the component in assuring process card and product tree are one to one correspondence, if pursue,5 are shown. Graph 5 component allocate (3) assemble ordinal basis the labour digit amount with preliminary and certain product line and assemble order, ship-fitter art card assigns corresponding work, use found automatically assemble tree tool to be founded automatically assemble structural tree. Undertake orderly according to the assembly of predefine fictitious assemble ordinal analysis, test and verify assembles order, find out unreasonable jockey undertake adjustment. (4) facilities of distribution program production and production system increasingly incline to is complex and costly, is very main. Be versed in through above an order decide really, the model of manufacturing facilities resource that has built early days form adds product line to assign work in, check product line content to shed passageway and stock space to whether have interference, can rise to optimize resource choice and the action that optimize distribution ahead of schedule so. (5) the operation time that the technology experience computation of the MTM of man-hour quota level that man-hour computation uses him and engineer oneself gives every pieces to assemble process card, be versed in every man-hour and metre undertake comparative, if exceed metre to represent worker worker working procedure should be adjusted appropriately too much, pass conversely little. What need a consideration likewise here is the issue that the production that confuse a line brings. (6) the line that the operation balances onefold model is very good implementation evenly, can move through the hand, semi-automatic reach full automatic go coming true, here uses software to balance a tool to undertake an analysis from the transfer matic of the belt. When the model more, when the production that confuse a line, the hand moves a line to be accomplished very hard evenly to the queen's taste, and need according to the spot actual condition undertakes adjustment. Xi Menzi transfer matic shortened not only evenly what the hand of experience sex uses flow chart of design technology program before is time-consuming reach later period ground the spot is real a large number of settling time of the circumstance, more important transfer matic provided many academic technology basis to the project evenly, the output of effective clarity analyses a report. very be necessary. No matter technology researchs in later period,plan so of new project of rationality and future carry out improve valuable technical data, avoid to be used of resource without foreword thereby. Pursue through Gannt (see a picture 6) can check each work very intuitionisticly, the working metre that operates a worker each. Graph 6Gannt pursues (7) assemble test and verify to pass above these measure, the craft information of the workshop basically is defined finish, to make craft information more accurate, must undertake test and verify to assembling craft. Of Xi Menzi Tecnomatix assemble program and test and verify, can be in the product that produces a high quality for a short while. The product reachs the synchro control function of production demand, the solution that passes test and verify through relapsing and optimal practice will decrease assemble program job. Additional, in assembling program and environment of test and verify to provide a kind of when research new technology and technology fictitious environment for the user, and heavy research and test and verify need not be begun in actual factory, use 3D to emulate a tool, emulate in detail whole rig a process, include component to assemble order, tool to interference is checked and be versed in among them a layout optimize etc. Also undertake man-machine project is emulated at the same time, include to assemble visible, can achieve gender and exhaustion to emulate etc. The place on summary put together is narrated, the Tecnomatix software that company of use Xi Menzi provides is solving automobile industry to digitlize very good result got on production problem. Extend the digitlization of the enterprise to production domain, enclothe production plans and transform whole production process. In the meantime, motor Corporation passes cup of China morning gold this system, also be gotten and accumulated technology knowledge and experience, formed optimal practice knowledge base, can plan quickly efficient product line and undertake old product line is transformed, shorten of new product appear on the market periodic, reduce the development cost of new product and risk, optimize products plan with benefit at treatment, optimize product line configuration and distribution, reduce product line preparation and machine down time, increase productivity of product line equipment, improve productivity greatly, improve work environment of the worker, improve product quality.
