In process of production of spaceflight product development, product tooling (abbreviation tool) design and make have very large proportion, the sort that every model place involves tooling and amount are very large. Although be versed in furnish is the auxiliary equipment of end item only fully, but from its process of design, treatment looks, it and product have the place of very big likeness. In large enterprise or business the unit is carried out almost or managing in executive product data (PDM) , we can draw lessons from the experience that product data manages and existing function, achieve the administration of data of pair of tool research and development. Academy of technology of flying boat of work of Chinese spaceflight family began to mix 710 in 90 time metaphase (predecessor of company of divine boat software) collaboration, the research that began AVIDM system with task form in institute of subordinate much home and factory and solid construction are made, move at was being popularized formally in complete courtyard 2005. Tooling is the indispensable material in product production process assures, the manufacturing process that sees whole product from the utility of tool cannot leave tool. Design and be being made of tooling is the workload in producing a technology to intend the work the stage with the biggest, the longest cycle. According to relevant data statistic, be in in the 50 ％ that the design of special tool in small lot production occupies craft to prepare workload with production job, large quantities of quantities occupy 80 ％ above even in production, and the 15 ％ of 10 ～ that the charge of tooling holds product cost on average above. Accordingly, the design of tool, make, use and management is measured to making sure the product is simple, shorten development cycle sense is great. As a result of the importance of tool, production enterprise takes tool design, production technology and tool control management seriously very much, the quality that tool design, made stand or fall develops to type product, plan and expenses have very big effect. In spaceflight production enterprise, the design to tool, make, the job such as quality control, management involved all cent factory and place room almost. Accordingly, build a scientific and effective tool to run a system to reducing cost, improve quality, shorten development and manufacturing cycle, valuable experience is accumulated having great sense. Be in my factory, run the application that waits for a technology as the product structure of the development of informatization technology and AVIDM, information of management of plan of job of autograph of careful of the management of tool product data that exists at present for the enterprise, flow, design, electron is shared and design, made collateral problem offer settle a way effectively, the process is carried out in old each informatization system in, we accumulated a lot of successful experience, fostered a batch of first-class technology staff. Because this is an object with the tooling of the enterprise, beginning the tool data that is based on AVIDM system to manage is practical. (one) the technology is feasible: Maturity of current AVIDM system technology, function is practical, and be in all courtyard of a few spaceflight, experience that carry out successfully; (2) management is feasible: The design as a result of tool, make close almost completely at making finish inside the unit, the enterprise has complete control to counterpoise to tool management, this is sure to carry out a process for the system coordinate between mid door, of regulations system make, carry out offer convenient; (3) the environment is feasible: The computer network construction of current spaceflight unit already was finished almost; (4) personnel deploys feasible: Have a batch to be engaged in informatization and tool management, design, administrative team. The function that builds labour furnish computation to need to come true according to running a system the first, the product structure means that is based on AVIDM realizes tool data management. It is fundamental general documentation with product structure to it associated, form a complete product structure tree, concentration reachs his to describe documentation to undertake operate and be maintenanced to product component. Such, facilitate the user uses an operation already, the complete expression that is helpful for data again and safeguard, offer all sorts of BOM view for each branches conveniently at the same time. Want to determine reasonable data size above all before implementation tool structuralization manages, assure the security of product data, validity and consistency. Offer a client to change the function of configuration management, can rise all project data that defines ultimate tool and graph documentation connection, realize the organization of data, management and control, mix according to certain regulation condition, to user or the different view that apply a system to offer relevant structure and description. Realize the following and basic function: Found and revise what BOM expresses, control of the inquiry of management of administrative levels of the many view management that the version control that BOM expresses, BOM expresses, structure, documentation, version, support " spare parts or child component by what the component is used " with " the component used what part or child component " . The 2nd, of three-dimensional CAD software and AVIDM system compositive. Tool structure cultivates building is job of base of tool data management, its validity and rationality also are later what all jobs begin is necessary assure a condition, and the structure cultivates generate basically originate product 0, the three-dimensional model structure of ministry package concerns. So, the stand or fall of the compositive job of three-dimensional CAD software and AVIDM system affects the use result of whole system directly. AVIDM software came true as compositive as mainstream CAD, make design data OK and fast in bringing into a system, come. The 3rd, other function. (one) tool design task plans to manage, include: The work out that the task plans, distribute reach refine, the real time of the task dogs the collect analysis of monitoring, task. (2) the job sheds management, include: The condition of object of the working shedding definition, flow control, data in watching flow and technological process, support the careful autograph of blueprint of 2 dimension electron and three-dimensional model. (3) as compositive as the 3D model tool that browse: Wait for a tool through compositive Jvue, PLM-Vis, provide data of CAD of compose of the different that browse, what support is based on 3D model is visible cooperate with. (4) attributive management: Include management of systematic function attributive and management of attributive of product object data. The implementation that tool complete lifecycle manages is designed with some enterprise tool, make, management is exemple, explore the administrative way of complete to tool lifecycle. The technical requirement of tool and the purpose that need to achieve design personnel to put forward by craft, tool designs the personnel requirement according to technologist and product technology blueprint, the state that joins manufacturing site undertakes designing. With tool application is start, after the task affirms, the member that design undertakes tool is designed and be according to final three-dimensional model in tool management system generate a structure to cultivate, other is begun to design the task, plan to dog on this foundation, the design such as count of documentation management, change management, flow management, subject product management, use case works, after the design is finished, by production the branch distributes the task to make a branch begin production to tool, production branch craft member so that the production news list in replacing a system in real time undertakes to creating position the problem that dog and appears is solved in time, make after finishing, affirm by relevant section and personnel, the put in storage that register and consign application unit is used, take-over by MRPII system right now management of tool objective information. Management of the tool in MRPII includes 6 functions: Code of user and attributive management, foundation is safeguarded, management of tool task management, tool platform debt, tool decides check management, tool to discard as useless management. The between each system compositive analysis in be versed in complete lifecycle of product of sketch map of furnish plan flow runs a course is shared to provide information, the consistency of the information between the system, basically undertake through BOM watch interface joins between the system, the difficulty of systematic interface basically is with outside system the interface between is designed, and of Ⅱ of AVIDM system and CAD, CAM, CAPP, MRP work to be produced to the scientific research of the enterprise in coordination smooth the effect that has having decisive. Basis 4 person between the particular case of relation and my factory: (one) CAM and AVIDM: Because both basically is a knife the documentation information such as code of file, NC, use application to enclose can satisfy requirement basically; (2) CAPP and AVIDM: Both besides having documentation communication, CAPP still needs to get equipment resource information, raw material information to wait from inside AVIDM system, reason uses interface exchange is equaler; (3) CAD and AVIDM: Because component describes attribute, BOM,the main product information such as the watch needs to pass interface exchange to guide from inside CAD AVIDM system, between both compositive strive for as far as possible close together. (4) MRP Ⅱ and AVIDM system are compositive, between the branch that is implementation design, craft and business management, production, qualitative check, finance affairs constitutionally compositive, it is product information at management information compositive, to assure its consistency of data, also need to be become closely thick and fast likewise. Enterprise informatization builds those who reach PDM system to carry out is a complex process, provider of personnel of engineering of the member that need enterprise decision-maker, informatization, business personnel and information system is various cooperation is finished. Product structuralization management is one of the the most important, most complex functions in PDM system, the perfect degree of this function is the main index that measures PDM product level. The function of product construction management of AVIDM system is cogent and usable, can more close together ground and CAD software are compositive. Structure of applied AVIDM product manages a technology to realize tool to design the management of data, what go up to reach software through running a system with other in this foundation is compositive, achieved the complete lifecycle administration to tool research and development and even hypostatic data.
