Depend on this to pile up the craft that recovers the part with as new as this similar part from inside the database to plan, undertake correction. System of mutation type CAPP needs to connect outstanding machine interactive mode. CAPP basically has achieve a few sort such as type, mutation type model. Starting type CAPP system is information of a can comprehensive treatment, make the system that gives procedure for a new part automatically. Because its are to be below the condition that did not intervene artificially from do not have those who creation comes out, because this needs many knowledge, and of knowledge getting is this system most scabrous problem, by accepted the " of bottleneck of a " in handling a process for broad sense knowledge. System of mutation type CAPP uses classification and coding system to press every kinds of spare parts classification of a few attribute and encode, coexist in the database, when the technology that makes a new part when need plans, these spare partses encode is inputted, next.
Depend on this to pile up the craft that recovers the part with as new as this similar part from inside the database to plan, undertake correction. System of mutation type CAPP needs to be opposite through interactive means additions and deletions of similar technology content, and cannot finish automatically by the computer. Shenyang is heavy-duty the sort of spare parts of blame swing tower with the craft relatively complex feature such as machinery plant casing, baseplate is various, the sex of disperse of process of treatment of spare parts craft of different type is extremely strong, and the process between series product has huge likeness sex again, accordingly, set out actually from heavy-duty plant, integrated mutation type and the advantage that achieve type, use integrated type CAPP(to start type partly) system, practice proves this system is provided more practical. 1 system is overall design 1.
1 overall program mixes mutation type achieve type union to rise, form the CAPP system that starts type partly to ask according to systematic target and function, the means with decision-making craft drew lessons from the thought that the knowledge base in expert system and inferential machine become independent each other, put forward to be decision-making mode of the foundation with the database, go up in this foundation.
Build a knowledge base in order to produce type regulation, carry deduction, have process decision-making, decide its process thereby. Systematic work flow, if pursue,1 is shown. 1.
Is the design system of module of 2 systems function main by advocate accuse module and: of 4 functions module? Cong of ⑹ of languid bank 4? Qin of haze of station of Luo ⒐ ひ ? Does Luo ⒐ ひ overspread Bo of Song of of account of calf ひ holding sb in respectful awe? Tiny fragments of stone of Fei of Luo ⑾ low thorough? ?1 of goblet mallet umbrella.
1 advocate accuse module advocate accuse what module uses at coordinate and controlling whole system to move, in advocate accuse module to fall achievable the choice to each function module and call. Nextpage 1.
Information of 2 spare partses inputs module the function of this one module is to guide an user to stipulate by the system criterion losing a person loses a person information of complete spare parts, the choice that realizes spare parts information by model of information of systematic spare parts, extraction and put store. 1.
3 craft are decision-making module the function of this module is a basis the spare parts conveys person message, use systematic technology knowledge and data to build the treatment course of the spare parts. 1.
4 technology knowledge base / module of technical data library the function of this module is to use the place in storing craft designs a process to use the data that reachs generation. From the point of the property of data, include static state and trends two kinds of data. Static technical data basically involves the relevant data that in supporting craft to design a process, requires. Dynamic technical data basically is to point to the pertinent information that designs the generation in the process in craft. 1.
5 systems manage module the function of this module is to use the senior management that provides a system, what data of knowledge of implementation system technology falls in different treatment environment is newer with safeguard, the foundation with decision-making craft lays in order to make a system in different environment. In network CAPP, return the attributive administration that can achieve an user. The system supervises the construction of module, if pursue,2 are shown. (1) attributive management, attributive supervises the particular case according to the enterprise, can install the user 〔 that has different limits of authority for instance administrator of director of systematic manager, project, average user, database) in order to assure the safety of business information and data data and stability. Every user has an entry code, and have corresponding operation limits of authority. (2) systematic database management, systematic database management offers an interactive friendly interface, undertake maintenance to systematic database. Database administrator is in what this can undertake a database to add, delete or revise. (3) craft library management, show the standard craft to already losing a person undertakes modification (4) management of library of company natural resources, company natural resources points to norm of the equipment of the enterprise, workshop, tooling, man-hour, material to wait. (5) systematic help, systematic help provides detailed use guide, the user can master the operation of this system quickly through it. The 2 classification that are based on product feature code spare parts information is the boy or girl friend that the system has craft is designed and basis, the computer still cannot resemble a person identifying all information on part drawing euqally at present, in the computer so interior must have a special data structure to have a description to spare parts information. Some heavy-duty machine plant is not swing tower spare parts to code the structure is to be based on a product to wait for the part that draft to classify encode, encode shares 7, represent 4 attribute, if the graph is shown 3 times, showed the meaning that everybody piles up. Nextpage for example, number shows mine equipment for K021255- - pink grinds machinery- - roller disk type grinds the roller embryo in coal machine. Additional, the graph name that uses encode of this kind of means and part has complete consistency, can change each other, because this passes this,the code is returned can undertake administrative to blueprint file. Roller embryo number is the procedure of K021255 spare parts, if express,1 is shown. The primitive information content that the designs heavy-duty plant CAPP system of 3 databases needs not only is big, and generates intermediate data and final data also are very giant and complex, and the relation between data and administrative levels sex also are of complex diversity. Because this need builds many databases. The need in this system builds model database of choice of technical data library, machine tool, mental allowance database, man-hour norm database, if the watch is shown 2 times, choose database structure watch for mental allowance. The system is in application, what apply to get used to a system is flexible, the technical data in the database and technology knowledge should have bigger extensive sex and flexibility. The intellectual data in technical data library, data that concerns treatment natural resources especially must agree with the actual condition photograph of the factory, namely the intellectual data in technical data library must be factory process capability, machine resource and technology experience, the true description that craft is used to, and more important is can mix as plant equipment the improvement of craft, undertake additive, change, found, with the content in deleting technical data library. This is about to beg a database must its have be safeguarded goodly and govern a function. 4 process are decision-making in CAPP design process, the most crucial question is craft decision-making. Craft is decision-making the craft feature that the process is mechanical spare parts essentially and the image process that machine a method, craft feature includes model face element (aperture, face, chamfer) , technical requirement, manage changes property to wait, treatment method includes to machine working procedure to be decided really, machine tool, knife, clip, quantity, complementary have a choice, the surplus between working procedure is made, craft diagram scale, some still includes man-hour norm to make even wait for content. Below the demarcate that producing condition of requirement of job of environment, production, production and manufacturing time domain, establish both corresponding relationship, concern this kind the main task that the model of legibility of translate into computer is CAPP. Does decision-making method divide the craft of CAPP kind of: ? ⒓ of to fold of M haze attacks cook over a slow fire of painful clump of Qiao haze Yao jumps J of haze to fold to guide system of solid Mo APP often applies above integratedly all sorts of decision-making methods. The calls; to will calculate decision-making at mental allowance applying day that this system uses procedure of logistic and decision-making implementation calculates, the computation of man-hour norm, computation of operating costs wait for; and applied creativity in machine tool choice decision-making will come true. Nextpage 4.
Of 1 mental allowance get in process of design of system of CAPP of spare parts of blame swing tower, does in v the need after corresponding process card content have two sort model correction job: ? Shine Suo embeds pregnant to ask fine gold of Fang of Yue of the americium that hand in a flat stone on iron rammer with ropes attached at the sides of of of Mi Nan Pan shine Suo embeds pregnant to ask the americium that hand in Yue Fang to Wen Kang of thick of Nai of vertebra of San of Xing of fine gold Lu seeks mental allowance of Qing ? get belong to a pair of formalization languages namely. When this is designing standard technology with respect to need, if how is "#" caught,be a special identifier before mental allowance.
If express,2 are shown. Be like:" The aperture inside half fine vehicle reachs end panel, every leave # mental allowance. "When advocate control a process from appearance of the v in project database when craft, to its content undertakes scanning operating, should read "#" , when character, want to decide mental allowance namely, undertake inquiring to craft content database, inquiry gives corresponding treatment method and machine tool name, again the dimension according to the spare parts, realize the choice of mental allowance finally. Mental allowance decides particular procedure is as follows: (1) builds a database according to machining technologist manual, mental allowance chooses database structure watch, if express,2 are shown. (2) is read from inside technical data library take treatment method, it is with lathe exemple, include car of thick car, half fine vehicle, essence of life. The acquisition that machines a method: ? Does narrow one's eyes of take along sth to sb ask ＜ of of elder brother of Qiao of サ of source of the americium that hand in Cong Quan to ひ exhibits charcoal does ㄖ school brag does narrow one's eyes of take along sth to sb of Li of regretful of ㄇ of commonplace し any of several hot spice plants ask the americium that hand in ?: ? Idle of breed of stitch the sole to the upper brushs? of location of reef king crab to be able to add before its % , its form is % fine vehicle, read when the program % when, read ever since two; are like half fine vehicle (3 character) two %% can be added before its, its form is %% half fine vehicle, when the program reads %% , read ever since 3, realized the contact perception to formalization language namely. (3) is read from inside technical data library take machine tool name, machine tool name can undertake reading extraction through procedure database, procedure database structure. (The basic measure that 4) adopts machine tool name and treatment method, place to machine a spare parts (length dimension and width dimension) calculative of mental allowance of affirmatory mental allowance is specific and algorithmic slightly. 4.
The choice Shenyang of 2 machine tools dimensions of some machine plant is giant, the sort of the machine tool is various, choosing machine tool equipment is one of important segment in process design. Machine tool choice can be mixed with procedure database database of machine tool choice is a foundation, particular procedure is as follows: (1) builds a database according to machine tool type. (2) is read from inside technical data library take machine tool name and treatment method, machine tool name reads those who take method and name of the machine tool in getting mental allowance course and treatment method with what machine a method take a method identical. (The geometrical measure that 3) adopts method of machine tool name, treatment, part and weight decide code name of machine tool type. (4) uses afore-mentioned methods to undertake inquiring can acquisition code name of type of many machine tools to the machine tool, these machine tool types made conflict part, because this need undertakes conflict clear up,decide conflict clear up is politic. When affirmatory conflict clear up is politic, should artificial intelligence theory and optimize a thought sufficient union rises, main from the following two respects regard: 1, the primary and secondary that distinguishs a machine tool to choose influencing factor concerns. Is the element cent that affects machine tool choice two kinds of big: ? Shine こ of bright Qiang commonplace kills where collate of Shan of blame of of Ge of ≡ of of vomit of Can of of of stand upright of Qiong of separate of Suo quiet collate chew Wan stops to need こ kills Huo of ⑽ of copy of Qiang of ⑽ of copy of Xiong of scene to show alarm Zhuo to delay deceive ⒗ to cast ぷ to save ⒐ Fei, wait like environmental tie, take after all restrain with how many kinds appropriate, decide according to the scale of production of the enterprise and manufacturing feature commonly, capture main demarcate element to capture those to machine a feature to ask to remove the factor of decisive action to the spare parts namely.
This system faces heavy-duty and mechanical manufacturing industry, outside be being restrained except the environment, consider the carrying capacity of the machine tool and power mainly even. After main factor is certain, below the premise that allows in hardware condition, answer to consider a few auxiliary factors more as far as possible, if load of workshop, machine tool allocates,wait for an element. 2, the relative stability that realises the machine tool chooses influencing factor. If the enterprise does not make major reform or product structural adjustment, so these influencing factor return the stability that can keep certain inside quite long period of time, choose afore-mentioned thought application at the machine tool in, can use conflict inactive strategy, machine the strategy of conflict clear up with total least cost. When many machine tools satisfy a requirement at the same time, the choice machines the machine tool with total least cost among them. Be based on content shedding to carry the strategy of conflict clear up with the shortest course. When choosing a machine tool namely, in other condition completely consistent premise falls, between the machine tool that should make choose as far as possible and a choose machine tool carry a course to be the shortest, through afore-mentioned conflict clear up strategy can realize the choice of the machine tool. Because 5 brief summary are heavy-duty the factory is large company, have _L art to design inflict to reach many cars to ask, in system of heavy-duty plant CAPP implementation network can realize enterprise interior what the iformation flow between departmental door, content shedding and capital flow is smooth deliver, made sure products plan cycle shortens thereby, all sorts of information such as machine tool equipment between each branches call, improved work efficiency. Because the CAPP system of this network should be,did not come to heavy-duty plant the development direction of CAPP system. CNC Milling CNC Machining
