From October 1964 American gold is cut since studying the company built database of cutting of the 1st metal jointly, world each country built all sorts of cutting databases in succession. The flying development of computer technology makes people be opposite of cutting parameter choose raised taller requirement, the digitlization of cutting parameter and share change had become hasten of general trends place. In recent years, more and more researchers and enterprise orgnaization began the development of cutting database, already partial investment is used, but database of a lot of cutting is in practical, share gender, compositive sex and open sex respect to still exist to be not worth apparently. Very difficult after development is finished promotion uses a lot of databases go down, repeat development the phenomenon is relatively serious also, this makes the cost that development database spends cannot get due redound. This has management and promotion to run the account that waits for a respect admittedly among them, but go up in the technology, the flexibility of cutting database is insufficient, construction of cutting database platform opens a gender insufficient, having toing break evolution also is main reason. The business object of cutting data, knowledge forms regulation and intellectual expression to existing the evolution of different level, because this need has a form,be built on professional cutting database more cutting data platform of the foundation. This platform can serve as professional cutting database system to move independently not only, yi Ke develops a tool with opening type as, supportive business function is patulous, and can ceaseless evolution, adaptability is stronger, applied range is wider, the function is richer also. The compose of business model builds the foundation to machine a process to undertake abstract analysis in the light of cutting, build model of business of cutting database base. If the graph is shown 1 times, this model basically is core with cutting parameter, add the business object such as fluid of the workpiece that its depend on, cutting tool, cutting, machine tool, refrigeration. To the description of workpiece, systematic regulation: Workpiece is mixed by workpiece stuff kind, treatment feature type, precision 4 large main types make exterior quality type and kind of workpiece stiffness feature, be short of one cannot. To the description of cutting tool information, the regulation is writtened guarantee by cutting tool 4 large main types make type of kind of form type, cutting tool stuff, cutting tool application and tool manufacturer kind type of business of cutting tool base. The description to cooling business object basically brings to bear on by cooling fluid type and cooling fluid kind kind is formed. It is with workpiece material exemple, compose builds model of business of workpiece data base (see a picture 2) . The necessary data that model of business of workpiece data base covered cutting database system to ask to workpiece stuff place, necessary data it is a system admit data must condition, lack an any information, data cannot be referred use. Fundamental business model raised the smallest requirement to data, if the data in this exemple should include state of standard of workpiece material brand, brand, heat treatment at least, but cutting sex group and but cutting strength group. To the base that often uses data undertakes abstraction and compose builds fundamental database, facilitate call, build contact and undertake knowledge classifies management, in be like this exemple but cutting sex group, child condition of group, heat treatment and standard of workpiece material brand. The business target that in seeing fundamental business model to facilitate the use person of cutting database platform does not have different meanings geography, involves, this system is used " data name + data explains + data citing + citation archives " means logarithm undertakes demonstrative according to attribute, establish corresponding regulation and standard. For example, be as follows to the description of attribute of brand of material of the workpiece in model of business of workpiece data base: · data name: Workpiece material brand; · data explains: String is to have a kind of number of identical and chemical composition, physics and mechanical performance data; · data citing: 0Cr18Ni9, inconel718; · citation archives: " classification of cutting database data is normative " , " cutting database data exchanges a standard " . Fundamental business model enclothed the the basiccest, most necessary data in data platform, be most " condense " data demand, all compose are built hereat the cutting database over platform wants comply with this data standard, can undertake on this foundation patulous, knowledge expands with business the function expands counting occupying. Model of business of cutting database base and cutting data platform are bound together, provide open data interface and professional work patulous interface, the compose that is cutting database not only is built reach a function to expand offer platform to prop up, also can share platform to independence moves and be used as data of cutting of a practicable. The kind that the knowledge of platform of data of Nextpage cutting expresses cutting data platform to use classified tree and attribute list has memory management and data classification and data structure to static knowledge build. Graph the 3 compositive evolution that develop for Beijing aerospace university software of platform of type cutting data advocate interface and menu of systematic model definition, the definition function of this system model can have the agile definition of structure of cutting data data, can go up from the function ceaseless evolution and undertake increment type expands. Graph the 4 classification that build for compose cultivate an interface, this platform can define type of object of cutting data business neatly to classify a tree, according to different classification regulation undertakes classified to cutting data. Specification of the name that business type basically defined classification to cultivate each node, code and encode standard. The classified method that classified attribute to define classification to cultivate a comply with and classification are regular, can classify attribute to undertake classified to cutting data according to what differ then. For example, the classification that if the graph is shown 4 times,according to the application of cutting tool means defined is cultivated, here " means of cutting tool application " the category that belongs to classified attribute. Classified tree is tectonic attribute of classification of functional criterion comply with defined the layer class relation between node. Diagnostic attribute defined all property that place of a node has, if the diameter of cutting tool, tine is counted,wait. Can according to object-oriented thought each node regard as kind, and the diagnostic attribute of node is corresponding kind attribute. Fundamental data table basically defined commonly used fundamental data kind, wait like workpiece data standard. Associated regulation defined the relation between type of each attribute, data, use for example " make an impact " , " match a relation " etc express the concern between intellectual node. People is a process that perfects ceaselessly to the understanding of cutting data, function of definition of this system model is a wide-open function, after the user wins limits of authority, can be based on this platform to undertake abundance expanding to intellectual description and data attribute, its adaptability, flexibility is relatively accordingly powerful also. The user can undertake maintenance to business object, undertake maintenance to cutting knowledge structure namely, make its have developmental function. The cutting database that on this platform compose builds although differ in thousands ways, but abided by identical knowledge to state a standard, and have common core data, because this is in,patulous respect also reflects data switch and function gave an advantage. This platform model defined a function to introduce object-oriented idea, can describe the domain problem of real world faultlessly, let more easily the person is accepted and understand. Of data platform function although cutting data platform can regard a cutting as the database,expand independence moves, but the diverse demand that faces people, need provides a kind of function patulous means. This platform supports plug-in unit to develop the function of type to expand, undertake with the mode of functional plug-in unit the function expands. If the graph is shown 5 times, functional plug-in unit is below the condition that obtains data to exchange compose of model of business of interface, comply with to propose an agreement, ask according to oneself function (optimize a function like what be based on production cost, data of economics of need production cost) raise data requirement to platform, the model that uses platform then defines a tool, compose builds the professional database of a need, and professional database can share alternant data with platform, have the aid of of functional plug-in unit realizes data at communication interface and professional database alternant, realize a function to expand then. Platform of this cutting data basically is those who serve as knowledge and data share platform, its advantage depends on can expanding ceaselessly, its vitality depends on can supporting the increment of countless plug-in unit to develop. Can platform is central database, with each major the database is branch workstation, with platform function + functional plug-in unit popularizes application inside bigger range to use pattern. The cutting parameter that this platform offers, be similar to equation of a broad sense: Y=Ax, in type, x is the input condition of the user, include condition of foregone craft setting information, tie and pursuit optimize a target to wait; Output condition Y is cutting parameter, machine means to what differ of course, the output of cutting parameter differs somewhat; A amount to occupies the intellectual matrix that platform place compose builds, the demand that is aimed at an user provides solution and intellective support. The data that functional plug-in unit enlarged to input, and dilate understands definitely the intellectual matrix A of the problem, abounded systematic content. The function that support of cutting data platform develops 2 times is patulous means, can agree with functional module data sends the form that be defeated, the abundance that is cutting database is perfect offerred a possibility, established the approach that shares data not only, also can undertake functional module share, namely the functional plug-in unit that armour develops can think second place is used, vice versa, this extended the open sex of this data platform further. The last word is current, web technology applies extensively at each domains, and more and more platform opening a source abounded software domain the function of software, attract more and more people to join. And in engineering field, do not have mode of this kind of development application almost in the development respect of cutting database especially, the development application of the cutting data platform that opens developmental type is planted to this mode undertook exploration. The pattern that with its open sex of height and supportive plug-in unit develop comes to this kind of mode integrated and numerous cutting database, the data that is vaster region is shared offer a technology to prop up. The cutting data platform that opens developmental type can be on the technology the mechanism that provides data management (if data visits attributive, data to share an agreement) , be data of cutting of different company, branch share provide technical safeguard. The plug-in unit type of platform develops means to have extremely strong vitality, in contractible development cost, integrated data reachs respect of intellectual natural resources to have stronger dominant position. The mechanism with ceaseless and developmental oneself of open data platform basically is the open sex that relies on its height is mixed share a gender, after use period of time, pass draw-out the data of general character of workstation of each function module, branch and function, adjust model of its base business, increase core function, newer data evaluates standard and relevant data agreement, realize the evolution of whole system then. The data switch pattern of the platform of open mode data that develops at present still is compared onefold, the database aspect that backing different manufacturer still is existing certain blemish, and just support increment to develop, those who increased data is redundant. How to solve the content that afore-mentioned problems will be prospective stress research better. The working pattern with this current platform is right solve before the practical, shares gender and development cost respect problem can yet be regarded as that cutting database exists a kind of relatively ideal application mode.
