The production of rigid production business creates pattern

They Decide How Innovative A Machine Builder Is, as Well As Its Production Capacity And Efficiency.

This Article Tries To Give An In-depth Analysis.

The analysis that the relation machinery of cost and batch produces an enterprise to produce production pattern is in traditional and rigid production business, production makes mode have sheet small lot produces pattern, group by group (in batch) manufacturing mode and mode of big batch production. In sheet in pre production, because use general machine tool and tooling in great quantities, manual operation holds quite large proportion, automation level of production is low, the amount of labor that processes production product is big, labor productivity is low. Although use NC machine tool and machining center, labor productivity also cannot with compare with mass-produced photograph group by group. In addition, because workshop, workshop section, group adopts the production that craft specializations to organize a form more, the parallel sex that produces a course and successional very poor, discontinuous time is more also in be being produced so, all these elements, make manufacturing management intricate, although use ERP to solve sheet very hard also pre production optimizes a problem, the manufacturing cycle that the influence makes to the product is lengthened, the number of turn-rounds of circulating fund is logy, make product cost rises thereby. Producing a condition to fall group by group, because crop is bigger, product breed is less, production is stabler, adopt partial automation equipment, special device and special class, clip, measure likely, the proportion of manual operation is odder a production is minor, because this reduced the amount of labor of the product, improved labor productivity. Because certain production segment is,organize production by object principle at the same time, equipment undertakes permutation by the flow direction of process, sex of successional peace travel is taller, the productivity of all sorts of link is the duplicates production product with main basis will calculate, the scale relationship between them is so more reasonable also, the discontinuous time that produces a course decreases accordingly, all these, it is shorten the production of the product is periodic, accelerate circulating fund have enough to meet need and the requirement with reduced product cost to create certain, the economic technology index that produces group by group wants prep above sheet production. Be in mass-produced in, because be used widely efficient automation, semi-automatic change equipment, special machine tool and special tooling, automation level of production is high, the proportion of manual operation reduces lowermost limit, to rise labor productivity is mixed reduced product amount of labor to create advantage. From go up analysis, law of batch of comply with of the technology of the enterprise, economic benefits, batch is bigger, cost is lower. On the other hand, the production of the enterprise makes mode type depend on the stability of product measure and production, repeatability. And use what kind of breed rotate the means, batch that decides every kinds of product is how old, this is problem of a particular kind that organizes production, method. In mechanical production industry, the breed of the product is much, structure and technology are sophisticated, and the progress of economic development and science and technology, need otherwise to judge the new product with ground trial-produce and much production again, impose the user requirement to product individuation, odd a production and small lot production are indispensable not only, and the trend that is development, this decided rigid production business belongs to 70~85% to produce mode and sheet group by group grain produces pattern. Because this research produces mode and sheet group by group the major task that grain production mode is business development. How is improvement produced group by group and odd the production mode batch of a pre production is custom-built the products plan process of custom-built production occupies the model batch of manufacturing products plan to report recently, already a few enterprises are undertaking changing to creating pattern, be like group of Dalian machine tool. Although in last few years, dalian machine tool is increasing pattern of level of product structure, product, management and the adjustment of production mode all the time, but because production lies from beginning to end the condition of a full load, did not vacate a hand to undertake production the adjustment of mode all the time. When the influence of global economy crisis is shown not completely still, dalian machine tool already of acumen feel, adjustment opportunity came, because this creates mode challenge to the tradition from ground of bold and resolute. Review course of study of world machine tool, even if be the country that develops again, the production of the machine tool is to use artificial operation since ancient times. And after the scale that just of Dalian machine tool implemented main products plan, production in the success is changed, to traditional machine tool production concept undertook overturning approximately with production mode of the gender change. With simple word is generalized, large quantities of system of quantities that use a car namely build manufacturing mode to manufacture a machine tool. Wei of ginger of division of total technology of group of Dalian machine tool explains so so called with the car production mode a future life produces a machine tool: The change of so-called production pattern, apply batch to produce pattern namely, the tall seed that Dalian machine tool produces oneself, efficient equipment, with compositive change, the method gather of informatization rises, composition is machined and assemble transfer matic, fulfil automation line school assignment. That is to say, from the wool blank of the machine tool the line arrives a finished product, it is online on efficient move. The change of this kind of production mode decreased to use industry measure greatly not only, improved manufacturing efficiency, reduced manufacturing cost, more important is to raise product precision and dependability greatly. As we have learned, at present the assembly of the lathe of Dalian machine tool and product of numerical control machine tool had completed the change of production mode, all " go up line " , its produce efficiency to make a person of the same trade stare: This group lathe distinguished a works in the past 2, 800 much people, one day gives 90 lathe at most, "Go up line " later, there are 400 much people only now, one day gives 150 the least. Dalian machine tool invested gigantic again last year, went up in base of production of lathe of tile-roofed house inn two product line, one machines a line, an assembly line, compare car product line namely even advanced one pace (car product line just is used at assembling) , these two lines turn entirely after rising, semifinished product goes in, those who come out is a product. The change of production mode improved manufacturing efficiency greatly not only, reduced manufacturing cost, more important is to raise product precision greatly. At present the dominant product of Dalian machine tool is the mainstream product of the market absolutely, user special approbate, because issue the product error wanting that come from transfer matic, and the demand of can seasonable contented user. Be like one aircraft group of Beijing again, be in manufacturing industry all the time on IT application lead position, win large award of CIMS project international, but of company efficiency rise to still depend on introducing the manufacturing industry such as Japan, Germany, France significantly the technology of advanced country and administrative technique. Pass study, mode of the concept of enterprise of machine tool of a pair of modernization, world-class, development mixes north the understanding that constituent frame had profundity. In north one big plant rivering bend is implementing products plan modular on the foundation, used lot custom-built production mode, the change is only in the past a model of batches of small production production, the heavy-duty planer-type milling machine that makes past north makes 5m of a width needs 3 years, a month can produce now 2, the Gao Lingren be left speechless with wonder or fear of efficiency. The backside of this kind of speed, it is 10 years solid transition changes. Employee by 6 2003, 000 people decrease do not come 2, 000 people, management department is adjusted through two by 50 cut it is 9. Labor productivity of average per capita: From 7-8 10 thousand rise 1.6 million, bright contrast showed the result of production mode transition. Through above 2 enterprises are carried out, to producing mode and sheet group by group it is feasible that grain produces mode change to use advanced production to create pattern and it is effective. Batch is custom-built in the batch law with the traditional development of the product research and development that produces pattern and concept of law of production method batch " batch " it is to point to goods lot, but the progress of the development as a result of economy and science and technology, need produces many new product breed ceaselessly, and of the user requirement to product individuation rise, decided rigid production business belongs to 70~85% to produce mode and sheet group by group grain produces pattern, how does applied batch law rise group by group, odd a pre production enterprise? Production of analytic company organization is the most primary is production of constituent working procedure, comprise component again on the base that working procedure produces, make a product finally. Batch is dissoluble for: Batch of goods lot, component and working procedure batch. Producing mode and sheet group by group so the although form large quantities of quantities impossibly,produces a business goods lot demand in company of grain production pattern, but the development that can press batch law concept, constituent component batch and production of working procedure batch gain the good point that batch produces thereby. Batch is custom-built the Nextpage of sketch map of advanced product research and development that produces pattern is modular product structure is batch batch of sketch map of custom-built creation condition is custom-built the pattern of product research and development that produces pattern (1) the inheritance of product information, although differ,custom-built product has certain difference on appearance and function, but the certain part in them has certain similar sex, can make full use of so the principle that becomes set technology and method, carry out the product information of test to passing production, accede before product information, workmanship information, raise the maturity sex of the product; In the meantime, the design of a new product needs no longer from 0 begin, shortened greatly products plan is periodic. Make full use of product function and diversiform of development of structural likeness sex are modular technology, include a component to share module technology (Component-sharing Modularity) , the component exchanges module technology (Component-swapping Modularity) , advocate get used to module technology (Cut-to-fit Modularity) , add module skill (Bus Modularity) , assorted module technology (Sectional Modularity) wait. Custom-built production organizes implementation batch new pattern (2) development design process recombines. The design method that is accepted generally commonly by design personnel, it is the design method that is based on a function, and every design a new product will be to be mixed independently brand-new, and batch is custom-built those who emphasize is not to design new component to use mature component however (module) assemble new product, it undertakes analyse and recombining to crucial process, so that will be separated artificially before but the mobile combination of mutual correlation rises. The products plan of custom-built production includes lot two large parts: Brand-new product development and custom-built product development. Brand-new product development basis is right the calculates the practical capacity with the factory analysis of the market, undertake the design of new product and standard module, this one process needs to have foresight and innovation sex, also have certain risk sex at the same time, its success or failure will very the destiny of earth influence industry; Custom-built products plan is the combination of a kind of groovy design, the specific requirement that basically needs according to the client in the contract chooses proper component to assemble a product, undertake changing to standard module by specific parameter model design. The seriation of product structure, generalization, standardization and modular the inheritance that presses product information, batch is custom-built the pattern of product research and development that produces pattern, traditional product structure to generalization, seriation, standardization and modular develop, for batch custom-built creation condition. Apply IT, thorough two change confluence, executive enterprise batch is custom-built batch is custom-built it is advanced production technology, IT is the technology raising a strike with the palm of the hand that implements advanced production technology, applied IT executive batch is custom-built be an enterprise two change development to be reflected shirt-sleevely with the target. What with IT implementation batch custom-built product development creates structure of new pattern product is modular these technologies already were in last centuries 5, 60 time already put forward, but what build a product with handiwork is modular design system is more complex (factory of the 2nd machine tool is in Beijing at the beginning of 80 time, those who use grinding machine of the garden outside be being built by hand is modular designed a system to use 8 years) , what support product construction as a result of what IT still cannot go to the lavatory at that time is modular design, but already blocked management to give priority to development to be the core PLM development with business compositive information by to in an attempt to in PDM of 90 time later period. At present PDM function is blocked besides the graph configuration of component management, structure and attribute data management increased to wait outside management, flow management, among them configuration of component management, structure and attribute data run development application, to build a product modular design system created a condition, it is important to become the new pattern that custom-built product development makes lot support, also be the hinge that produces PDM effect. The application of these module formed batch the products plan environment of custom-built production and working platform, mode of will changeable traditional products plan and make plan mode, also developed mode to offer a technology to support to change traditional business economy. Creation realizes batch with MRP/MRP-11/ERP at present MRP/MRP-11/ERP function wants new pattern of custom-built production organization to apply neatly only, can organize batch completely custom-built production, next graphs are creation with MRP/MRP-11/ERP implementation batch custom-built production organizes new pattern.
