The engineering technology research that cutting of car mould high speed machines and treatment of cutting of applied high speed are the development climate that contemporary car mould creates. Engineering technology of high speed cutting is one of crucial technologies that high speed cutting uses. The article introduced the technical measure that craft of cutting of car mould high speed studies, discussed to develop the technical line that craft of cutting of car mould high speed studies, combinative example introduced engineering technology of high speed cutting to enclothe a mould to make medium application in the car. Treatment of high speed cutting is a kind of the processing technique of cutting of development trend high speed that car mould makes is 21 centuries advanced production technology, having powerful vitality and wide applied perspective. Can solve through processing technique of high speed cutting in car mould convention cutting is machined in a series of problems that get a worry fully. In last few years, in the cutting of high speed of industrial developed country such as the United States, Germany, Japan processing technique was in major pattern company to get applied extensively, working procedure of 85% form cutting of mould electric spark already were replaced by high speed treatment. Part of high speed processing technique is efficient, high grade, small bad news at a suit, already made the main trend in international mould workmanship. The processing technique of high speed cutting that makes a trade through mould of domestic and international car carries out application, processing technique of high speed cutting has following advantages: One, treatment of high speed cutting rose to machine cutting of speed high speed with cutting of prep above convention 10 times cutting speed of the left and right sides undertakes to car mould high speed cutting is machined. Because main shaft of high speed machine tool stimulates Zhen Pin rate to exceed far " machine tool, cutting tool, workpiece " natural frequency limits of the system, process of car mould treatment is smooth and without concussion. 2, efficiency of production of treatment of high speed cutting uses high speed machining center high or high speed milling machine machines a mould, can install in workpiece finish in clip model the thick, finish machining of the face and car mould are other the machining of place, namely alleged " pass " technology (One Pass Machining) . The application of processing technique of high speed cutting raised the development rate of car mould greatly. 3, the because took minimum,machines the surface step pitch that treatment of high speed cutting can acquire high quality and cut deep, treatment of high speed cutting can acquire very high surface quality, OK even leave out benchwork overhauls smooth process. 4, simplify treatment of milling of treatment process convention can be in only quenched ongoing travel, quench cause be out of shape must want nap of deal with labour or use report to machine final take shape. Can pass treatment of high speed cutting to finish now, and won't appear the case hardening that electric treatment brings about. Additional, as a result of cutting the quantity decreases, the cutting tool that high speed treatment can use smaller diameter reachs mould detail to undertake machining to smaller round horn radius, saved partial machining or manual nap working procedure, shortened thereby production is periodic. 5, treatment of high speed cutting makes process of car mould repair becomes more convenient car mould often needs repair for many times in use process in order to prolong service life, if use treatment of high speed cutting to be able to complete this work quickly, obtain the treatment result that grinds with mill generation, and can use former NC program, need not new process designing, and can accomplish do not have accurately by accident. 6, treatment of high speed cutting can machine the horniness car pattern with mixed appearance by mechanism of high speed cutting knowable: When high speed cutting, cutting power decreases greatly, cutting process becomes easier, treatment of high speed cutting has larger dominant position in cutting high strenth and side of tall hardness data, can add a tool to have complex model the car mould with face, taller hardness. The processing technique of cutting of meaning high speed that develops research of engineering technology of cutting of car mould high speed made an industry receive wide application in mould of domestic and international car, and already gained tremendous benefit, but the mechanism that high speed cutting machines and relevant theory still are not perfected up to now, the database of high speed cutting that is aimed at car mould had be notted build. The means of parameter of cutting tool of cutting of high speed of option of domestic and international company and parameter of treatment of high speed cutting still with the tradition " try cut " law and " experience " the law is given priority to, when processing some one new-style data, often need to use a variety of cutting tool to undertake cutting experiments repetition, study those who analyse cutting tool to wear away, damaged means and its reason, find out material of cutting tool of a group of first-rate and treatment parameter from which, turn over Fu for many times so, blindness is big, and waste much labor power, financial capacity and resource. And be like alloy steel of alloy cast iron, high strenth, super alloy in the light of special type material (the alloy that be like titanium) the treatment of high speed cutting that waits for material, how to choose appropriate cutting cutting tool according to material character, how to design reasonable cutting parameter, in still studying at present and developing. Build and use of the database about high speed cutting, the document that concerns domestic and internationally rarely up to now reports. Because processing technique of high speed cutting starts,this basically is late, the data of cutting of practical high speed that can be used at production at present still is lacked very. The research of processing technique of cutting of high speed of mould of our country concerned car starts later. In recent years, numerous pattern company bought a large number of high speed to machine equipment and cutting cutting tool from the country such as the United States, Germany, France, Japan in succession, the engineering technology that fumbles in practice cutting of car mould high speed is machined, gained a few successful experience. But, on one hand, imported equipment is equal to introduce a technology. High speed cutting especially the aspect of high speed cutting that large car covers a mould, can offer without successful experience draw lessons from, how making introduced device produces due effect as soon as possible is the problem of one a lecture given to a large number of students before the person that place in business management and project technology personnel; On the other hand, technical personnel learns edge application in the edge in the job, fumble, parameter of the example of treatment of high speed cutting with was accumulated certain, craft and working experience, how to save these valuable experience and homiletic summary draw lessons from for other technology personnel, avoiding to take roundabout way more also is a difficult problem. Car pattern company should build a high speed to machine cutting database not only, and should be to be aimed at a car to enclothe a mould of treatment spy a note of the ancient Chinese five-tone scale " characteristic " cutting database, the cutting database that builds namely not only can store parameter of high speed cutting, and can store outstanding high speed cutting machines example and decision-making knowledge, accordingly this is can " grow knowledge automatically " database; On data and experience foundation, still need to machine job of job of numerical control process designing to undertake administrative effectively to high speed. Build a such databases that are aimed at pattern company distinctive condition, already was head and shoulders above the category of general cutting database, but this kind " characteristic " the build and applies sure meeting to raise car mould high speed to machine quality of the database and efficiency, bring considerable economic benefits for the enterprise. The content that engineering technology of cutting of car mould high speed studies one, the time that the processing technique of cutting of research high speed of mechanism of treatment of high speed cutting is growing domestic and internationally is short, cutting mechanism respect still has a lot of content to still need to study further and be perfected, main show is rising considerably as a result of speed, the cutting force that machines process generation, heat in metal cutting, cutting tool wears away the phenomenon that state and treatment surface circumstance will machine corresponding element place to arise with the tradition and the result that create differ significantly. The lack of mechanism of high speed cutting uses the development of processing technique of cutting of block up high speed, because this wants to undertake high speed cutting machines the research of mechanism above all,be opposite in order to deepen technical personnel and operation personnel the understanding of processing technique of high speed cutting, make full use of the treatment that processing technique of high speed cutting covers a mould to have efficient high quality to the car. 2, of parameter of treatment of high speed cutting optimize practice proof, reasonable treatment parameter is used to will improve work efficiency greatly below the circumstance with equipment, material, politic and fair treatment, accomplish treatment to efficiency, cutting tool wears away and machine the optimal combination of quality. Accordingly, a cutting of mould high speed is being enclothed to machine a respect to undertake parameter is optimized machining in the car is to raise work efficiency and car to enclothe a mould to machine segment of a of quality main technique. 3, the fundamental premise that strategy of treatment of cutting of high speed of mixed pattern curved surface studies to undertake high speed cutting is machined successfully is to bear approximately constant cutting load, can make sure below this kind of condition good high speed cutting machines the effect. Be aimed at mixed pattern curved surface, bulk of material of the purify in needing to undertake machining a process changes the treatment strategy with constant load of small, cutting studies in order to avoid cutting tool faster wear away and reduce error letting a knife. 4, database of cutting of treatment of car mould high speed builds high speed to machine cutting database to store the data such as parameter of high speed cutting offers technical personnel and operation to personnel inquires and be used, in management technical data and auxiliary technology personnel undertake technology program respect is having main effect. To increase technical personnel and the work efficiency that operate personnel, stimulative business stability develops continuously, build the cutting database that covers a treatment of mould high speed in the light of the car imperative. The technical method that engineering technology of cutting of car mould high speed studies one, cutting treatment is finite the flying development of technology of yuan of imitate technology computer makes use numeric imitate method to study cutting machines process and the relation between all sorts of parameter to become a possibility, only then what at going up the metallic cutting of 70 time machines the century is finite yuan of imitate technology development in computer technology is medium also got great progress. What metallic cutting machines is finite yuan of geometry condition that imitate considered material attribute, cutting tool, cutting machines parameter (deepness of cutting speed, feed, cutting) and the element such as the cutting power load that cutting treatment causes, hot load and leftover stress. The foundation with test and verify is assisted to go up in the experiment, fictitious cutting machines the action process that the cutting tool in the process and spare parts move relatively, undertake dynamic physics emulate to cutting bits figuration course, can show the distributinging case of treatment behavior and the physical quantity such as the temperature that be mixed by rate of the in-house stress of treatment spare parts, meet an emergency, meet an emergency, the treatment quality that casts a part and cutting tool wear away, the circumstance such as damaged. Then, pass pair of craft parameter optimize, can improve the treatment quality of the spare parts, reduce cutting tool effectively wear away degree, reduce the high cost that when using traditional trial and error procedure to decide new technology, requires and time. Additional, when metallic cutting machines imitate, can define relevant element (condition of geometry of treatment parameter, cutting tool and the upper limit of hot, force) the relation between the purify rate with material. Below the premise that ensures the spare parts machines quality, raise the purify rate of material through changing cutting parameter, achieve the goal that improves productivity thereby. The car enclothes a cutting of mould high speed to machine mechanism and treatment parameter to optimize a technology to involve physics of material science, mechanical, metal, machinery to make wait for many course, solve hard all the time in CNC Machining domain. Existing CAM software can according to the spare parts a note of the ancient Chinese five-tone scale of curved surface spy undertakes numerical control process designing, assure a knife orbit does not collide, hands-off, but the spare parts after assuring to machine hard is on the physical target such as exterior quality and cutting tool life also is best, often cause product precision low, cutting tool wears away serious, machining a process to undertake optimization is analysed to high speed cutting so is a task with compare difficulty to comparative again however main. Machine from afore-mentioned cutting finite yuan of imitate technology overview in light of, imitate of word taking number emulates the way that ties with experiment research, it is to solve this significant step of real problem. Cutting process and those who cut bits figuration course is finite yuan imitate studies for development cutting mechanism, raise cutting to machined quality to offer new, more effective analysis method. 2, the inference that is based on the high speed cutting of example inference to machine database compose to build a technology to be based on example (CBR, Case-based Reasoning) traceable 20 centuries seventies, it is the mode of a kind of inference that artificial intelligence technology appears in development process. Say simply, the solution that uses similar before problem namely and knowledge will resolve new issue. Be based on example inference is a kind of inference means that is sought to divide a territory at all sorts of problems by wide application, apply method of this kind of inference to beg solution problem not to rely on the regulation of a domain of the problem that seek solution, rely on the experience that accumulates before and the similar example that solve successfully however. This is close to the train of thought that solves a problem at human expert and method very much. Actually, the technology that is based on example inference is a kind of problem seeks solution means, applicable at numerous domain. The domain is machined in cutting of car mould high speed, the element that the problem begs solution to want a consideration is very much, the certain part of the solution can decide with simple regulation, but below most circumstance, want to notice the particular case of real problem. When be like choice cutting cutting tool, cutting tool type can apply regulation very simply to decide, but what wait for data like parameter of model of angle of cutting tool dimension, geometry, razor blade, dimension, angle, treatment is affirmatory, decide very hard with simple and effective regulation. Sometimes, use certain the regulation that has existed brings about wrong conclusion possibly even. Below this kind of circumstance, the inference that application is based on regulation got very big confine, use method of figure of artificial nerve network the blame numerical value of domain of very unmanageable problem data, and the technology that application is based on example inference will solve such problem to overcome afore-mentioned difficulty very easily. Additional, as a result of accumulated experience little, in process of treatment of high speed cutting, of spare parts and cutting tool material best match those who reach fluid of the choice of cutting dosage, cutting to choose, machine tool tigidity and workpiece tigidity are opposite of the influence that machines precision and exterior quality and cutting method and machine tool choose, between cutting tool life and cutting dosage and finished cost reasonable match, spare parts and, also cannot express with simple formula or regulation. And these information and experience are right sense of technology of cutting of promotion high speed is great, it how be collected accordingly and be handled is very important to how be collected accordingly and be handled. And the methodological as it happens that is based on example inference to solve a problem can use afore-mentioned experience and treatment example to solve high speed cutting to machine what appear in the process all sorts of problems. Below the circumstance that at present domain of treatment of high speed cutting lacks the cutting data with a large number of applicable systems, experience and regulation, application is based on example inference technology to solve the thoughtway of the problem, can be build processing technique of cutting of high speed of database of high speed cutting, promotion, offer a practical way. Graph the technical course of engineering technology of cutting of high speed of mould of car of course of technology of research of technology of cutting of high speed of 1 car mould with finite compose builds yuan of imitate technology and the database of high speed cutting that are based on example inference the technology props up a technology for research, wait with theoretical analysis and experiment research to assist a technology, enclothe a cutting of mould high speed to machine craft to develop thorough research especially to car mould. Its study the process is: Have stuff above all mechanical function experiments, use test data compose to build finite yuan of model, discuss high speed cutting to machine mechanism, optimize high speed cutting to machine parameter and announce high speed cutting machines the rule; Be based on optimized treatment parameter source data and law of treatment of high speed cutting, use example inference method to build database of high speed cutting; Research has complex curved surface special the car of a note of the ancient Chinese five-tone scale enclothes a mould to keep approximate and constant the treatment of high speed cutting of cutting load is politic, break through 3 ＋ key of means of 2 axes CNC Machining uses technical segment, development car enclothes a mould 2 axes CNC Machining assists 3 ＋ process designing tool, it is these achievement finally in treatment of cutting of actual high speed undertake applied. Graph 1 to study course sketch map. Graph the 2 cars that have on high speed machining center enclothe a cutting of high speed of mould of car of milling of mould high speed limited company of pattern of car of east wind of example of engineering technology application is dimensions of industry of domestic car mould one of companies with the biggest, the most advanced technology. Begin from 2000, this company organizes technical personnel to undertake processing technique of high speed cutting studies, what marriage car mould enclothes a mould to make especially is actual, solved a series of crucial technologies, summed up to suit a car to cover the technical program of a treatment of cutting of mould high speed and method, include: The car enclothes the basic idea of a treatment of cutting of mould high speed; High speed machines the standard of choose and buy of equipment; The installation of machine tool of high speed treatment and debug; The use of cutting tool of high speed cutting; Agree with the CAM software that high speed cutting machines; "Processing technique of cutting of high speed of 3+2 " axis; Craft of treatment of high speed cutting and measure a technology to wait.
