In equipment the craft in production enterprise is designed is connection products plan and the important link that the product produces, it is one of main manufacturing preparation jobs. Jinan the CAD/PDM/ERP system that base oneself upon of limited company of group of 2 machine tools has at the enterprise, according to machining, assemble, the order of hot-working, be developed early or late and carried out fit this business the CAPP system of different technology major, the article introduced effect of the functional characteristic of CAPP system, application and executive process experience. One, foreword Jinan limited company of group of 2 machine tools only then built 1937, it is one of 520 when national emphasis supports large companies, main product has: V equipment, gold cuts facility of machine tool, automation, cast building materials of mechanical, environmental protection, 6 class such as machine of numerical control cut provide the product of competitive advantage each. Dominant product home market is had rate amount to 70% , sell as far as to 50 many nations of world and area. In last few years, develop as the abidance of the enterprise, the enterprise leads a layer to realise adequately: The enterprise wants to hold position and win out in intense market competition, must enhance oneself core competition ability ceaselessly. In equipment the craft in production enterprise is designed is connection products plan and the important link that the product produces, it is one of main manufacturing preparation jobs, the information such as the treatment method that technology design produces and technology natural resources is direct company goods and materials purchase, the important basis such as balance of production of manufacturing planned dispatching, tissue, resource, cost accounting, because this craft informatization is the crucial link in enterprise informatization. The products plan of 2 machine tools uses Jinan already CAD undertakes, design information undertakes administrative through PDM, the ERP of manufacturing management system of the enterprise moves already successfully also old, built many fundamental resource warehouse, of these information natural resources build offerred very advantageous condition for system of the CAPP on the enterprise. But handiwork still is passed all the time before the craft of the enterprise is designed will undertake, did not make full use of already some information natural resources, want to do many repetition to work not only, procedure design efficiency is low, the technology prepares cycle to grow, and the consistency that unwarrantable craft designs, standardization, go against advance craft standardization, guarantee against craft designs quality. Because this makes full use of to some is designed and already produced resource, build the CAPP system of a technology design that fits this business and management, can raise craft to design a level not only, and the core competition ability that can enhance a business effectively. 2, the content that craft designs and the requirement to CAPP system 1. Before the content that craft designs already the first pace that remark technology design is work of manufacturing technology preparation, it is the decisive job in production. The main task that craft designs is to be machined the spare parts chooses reasonable treatment method and treatment order, so that can press a design,demand production gives eligible finished product part. The content that industry technology designs, include norm of computation of norm of design of craft course work out, procedure, material, man-hour to make, the spare parts carries early days to slant unit of the setting of buy period, production is appointed, tool design and procedure list pool. The process that craft designs is the member that be in charge of craft designs a branch to get part drawing paper from upper reaches above all, the work out gives the craft line of the spare parts, next craft member according to craft course, the analysis concerns the information of the respect such as public errand of appearance of spare parts structure, dimension, material and batch on blueprint paper, the information of the respect such as condition of facilities of treatment method, treatment, production, finished cost is concerned in combining treatment to make, the work out gives the procedure of the spare parts. When work out procedure, need undertakes material norm is calculated, manufacturing unit is appointed, and the setting that the spare parts carries early days, when work out working procedure, need chooses to machine a method, consult equipment library chooses to machine equipment, consult tool library chooses tool, the need when if do not have,retrieving the tool that accords with a requirement undertakes tool is designed again. The enterprise has his typical technology, because this is weaving when a new technology, can make full use of already some typical craft, will save technology staff time greatly so. After procedure work out is finished, by standard man-hour norm member basis procedure and business norm level will make man-hour, submit craft information ERP database at the same time, will organize cost of production, business accounting according to this, purchase etc. Final collect makes procedure list, along with procedure together, allot a workshop, machine the main basis that makes with tool as the spare parts. 2. Technology design is narrated on the requirement put together to CAPP knowable, technology design is concerned with products plan already, produce with the enterprise again closely related. 2 machine tools carried out Jinan early or late CADERPPDM system. When products plan branch is undertaking CAD is designed, optimize design construction ceaselessly, built many general part, PDM of design information classics undertakes unity administrative. On the other hand the enterprise is when executive ERP system, undertook to company natural resources sufficient argumentation is analysed, built equipment to code course of library, craft codes unit of library, production codes center of library, work codes library, only () code with tool library, material codes the company natural resources such as the library fundamental library, what technology design uses these fundamental databases. When applying manual means to undertake craft is designed, cannot use these to already had resource, still need to consult by hand craft manual, repeat data-in. Because this craft designs the requirement to CAPP,share adequately namely above all already some data and graph library, carry data for ERP, guarantee against repeats data-in, raise consistency of data and compasses plasticity, the efficiency that improves craft authorized strength and craft design a level. 3, the engineering technology personnel of company of group of 2 machine tools is engaged in the functional characteristic Jinan of CAPP system respectively machining, assemble, forging, cast, heat treatment, and solder wait for different major. Before CAPP system is developed, procedure design weaves except partial handiwork outside, one part has applied WORD to assist undertake, procedure has been digitlization by paper change, reduced on certain level duplicate work. But the problem with still exist particular, procedure pattern plate is for instance skimble-scamble, data cannot be shared, technical data cannot be mixed ERP is direct and compositive, craft file did not get administrative effectively, cause retrieve difficulty, already some procedure are couldn't get use effectively, craft parameter still should search craft manual by hand, craft catalog needs manual collect to wait a moment, the efficiency that these problems are affecting procedure to weave and the quality that craft designs. To solve these problems thoroughly, the CAPP system that the requirement develops, must have following functional characteristics: 1. According to each professional characteristic, build corresponding procedure pattern plate to consult national level and industry standard, course discussion decides finally, built machining respectively, assemble, forging, common heat treatment, intermediate frequency heat treatment, solder spare parts and solder the professional procedure card pattern plate such as structural member. Inside pattern plate of each procedure card, include corresponding technical data model. When using CAPP system, the user chooses different pattern plate, the system shows different program interface accordingly, input relevant information according to diverse professional demand. Each procedure card pattern plate become independent each other, program function and data are shared each other, the profit that such doing is clarity of model of data of different pattern plate facilitate the system is safeguarded again. 2. Between mature CAD/CAPP/PDM/ERP each system share and when compositive CAPP system is developed, mature be shared with what have CAD/PDM/ERP system and compositive, do not cause repeat typed phenomenon. Particular system is as follows now a few respects: (1) share a spare parts to design information (refer to a graph 1 interface) , after choosing pattern plate of good procedure card, need to input a spare parts only date, criterion spare parts name, capable person is qualitative, weight, single the information such as stage amount is straightforward from take out inside the database; (2) share part drawing paper, when technology design needs process chart, OK and direct pursue the CAD electron that has drawn, duplicate and stickup to revise inside procedure can. (3) share information of company natural resources (refer to a graph 2 interfaces) , when work out working procedure, when needing the information such as center of choice device, work or tool, need to input corresponding retrieval only condition, system can direct from corresponding news is taken out inside the database. (4) after procedure design is finished, the norm of the spare parts is heavy, gross weight, man-hour norm, semifinished product date, manufacturing unit, carry early days, and part process date, working procedure code, working center, technical condition waits craft information a moment, refer ERP system directly, need not repeat again type. Graph Nextpage of interface of editor of 1 craft card pursues 2 craft edit an interface 3. The computational foundation that sets quota of material of norm of timing computation material in procedure of forging, weldment different, each have different computational method. With weldment for, divide the steel that it is a circle and profiled bar again, divide again inside profiled bar for distinct category, inside CAPP system, embed the norm computation formula of distinct category material in the system respectively, when procedure is designed, input material encode, the system chooses corresponding computational formula automatically according to material name, calculate thereby a corresponding norm is heavy with gross weight. 4. The system is built and have library of standard working procedure and ground of special symbol library the similar sex principle of the spare parts, built warehouse of multinomial standard working procedure, the appearance feature that presses a spare parts respectively and treatment method cent were become a certain number of kinds big again fractionize arrives group. When system of procedure application CAPP, can undertake retrieve and be callinged quickly directly. 5. When be based on typical craft and product craft to undertake craft designs procedure, it is to be redesigned directly rarely, it is to be on the base that already had technology, undertake modification finishing new technology. Because this CAPP system must be had,be based on typical craft and product craft to have the function of the design. Besides build typical craft warehouse, still built the man-hour norm warehouse that is based on typical craft, after procedure is finished, man-hour norm also can be based on library of typical man-hour norm to finish, not only efficiency rises greatly, also rise to optimize action certainly to the generalization of spare parts procedure, standardization at the same time. 6. After work out of procedure of catalog of card of automatic collect procedure is finished, want to have pool to procedure card catalog, before using CAPP system, it is to undertake typing by hand, also be innovation meaning is without again between a take time duplicate work, after using CAPP system, while this job is handling craft information, automatic collect is finished. 7. Batch prints procedure card the procedure of a spare parts is little a 9 pages, many a few pages, the printing take time of individual spare parts is arduous, the lot that uses CAPP system prints a function, already can odd piece it is OK also to print batch is printed, efficiency is tall, go to the lavatory neatly. 8. Before attributive management already remark, craft designs cent to be different major, different professional technologist, to the visit of craft graph library the requirement is different. What visit e.g. machining technologist is library of machining craft graph, assembling what technologist visits is to assemble craft graph library, what hot-working technologist visits is library of hot-working craft graph, so the system must have attributive management function, according to the part of different technologist, gift different visit limits of authority. 4, system of CAPP of limited company of group of 2 machine tools is able to develop CAPP system executive application and effect Jinan successfully and carry out, what cannot leave leader layer above all is correct and decision-making and support energetically, it is the management department that the director implements next the measure that the organization implements is capable, together with user cooperates closely with what develop personnel, make CAPP system is inside two years of short time from machining, assemble, wait for 3 different major to hot-working progressively success carries out application inside limits. So far, jinan machining of limited company of group of 2 machine tools, assemble, hot-working already applied CAPP system to undertake craft is designed entirely, pass the application of CAPP system, the bridge with current data rose in the form of a Chinese character of CAD/PDM and ERP system, those who realized CAD/CAPP/PDM/ERP system data is compositive and share, shortened from whole technical preparation is periodic, the work out efficiency of procedure gets rising further, the compasses plasticity that procedure designs got unity, had safe and effective government to craft documentation, whole craft designed a level to get promotion. 5, CAPP system development and design of executive experience technology are a when matter to business life directly very main technology job, the horizontal discretion that craft designs and efficiency discretion, affect the core competition ability of the enterprise directly. Because this applies CAPP system to undertake craft is designed, it is urgent affairs to the enterprise. The enterprise wants the case according to oneself, the decision is to introduce CAPP system to perhaps be developed by oneself. System of the CAPP on the enterprise, do not have with the CAD/PDM/ERP on the enterprise early or late cent, but must have overall planning, no matter that is to say goes up first which system, want those who be other system to carry out in the begining in the project do good overall situation to intend the work. Be opposite next for an enterprise, the development of CAPP system or introducing is only on one hand, of the system carrying out is a very important segment, in systematic executive process, management, development and user tripartite must cooperate closely, mix in order to manage especially among them development is most important, development staff is in intermediate link, want to listen to the requirement of the user patiently on one hand, take out as soon as possible solve a problem to develop plan, want to be mirrorred in time to administrator to a few difficulty of the user on the other hand, get the support of ranking leader. As long as science is reasonable, measure is proper, the objective is firm, the project carries out a success with respect to regular meeting. 6, the development that the last word adopts CAPP system and application, drove the progress of industry technology informatization, raised the integral level that craft designs, at present the enterprise is extending three-dimensional design and the PDM system that are a foundation with three-dimensional design in the round, craft is designed will the development as enterprise informatization, stride to higher end ceaselessly.
