Css" Type=text/css Rel=stylesheet> controls technical development as contemporary number, of numerical control machine tool popularize degree to get rising quickly. As the arms of the person at the head of a procession that creates technical application field in numerical control, through 20 old accumulate quickly, aerospace company already bought CAD/CAM software not to think from in the past with, use CAD/CAM technology as indispensable main technique truly to now, this also enough report gives his " lead technology lays in the strategy " necessity. If hypothesis introduces the CAD/CAM system that the price does not poor without decision-making in the past layer, also will never aerospace CAD/CAM technology applies today. Review domestic main performance to be: Although equipment of hardware of war industry production system reached higher level, but still put in bigger difference on production level of true high accuracy; To hi-tech method, the enterprise has taller self-identity to spend, with respect to domestic informatization character, because the enterprise has the excessive exclusiveness of software and information system, and bring about more high accurate production technology to be apart from outside the door; The software of the enterprise is in as initiative software tool merely use, and do not talk to go up the soft equipment of real significance, the soft equipment that should promote software tool to serve as an enterprise still has a paragraph of very long way to want; Go to introduce truly, break restrict development and idea to guard; Avoid environment of as same as abroad hardware, software, and the circumstance of production efficiency and precision great difference happens. The settlement that the article is based on control of CNC Machining quality to be short of annulus below, CNC Machining gets used to precision of craft of machine tool of technology, numerical control to detect oneself wait for a technology, and be based on Delcam to be in machine detect technical implementation craft and quality automation undertake respectively preliminary discuss. One, CNC Machining process is not controlled, the craft that is informatization is short of what annulus creates demand as aerospace company to rise, very tall to machining the requirement of precision and quality stability, quality of CNC Machining process detects also got more and more enterprises take seriously. Some aviation industry is in part production process, should undertake detecting to metric center between the working procedure of process of its CNC Machining, and the machine tool stops machine need check, numerical control machine tool arrives 3 coordinate, return numerical control machine tool next, relapse for many times so, decide whether below one working procedure undertakes; And the spare parts arrives finally eventually check remains waste. Analyse problem reason, depend on more link existing to accuse. In production process, the spare parts is in numerical control machine tool and enterprise have enough to meet need relapses between metric center CMM. Locating to avoid process of have enough to meet need and spare parts to return numerical control machine tool to search, and occurrence stress is out of shape, CMM detects the mistake risk that exists possibly, use in machine detect technology (the generation of the risk that Delcam OMV) can avoid effectively to exist in CNC Machining process and worthless cost. For this, we can raise the following question: Carry workpiece to measure the cost of machine to 3 coordinate? How to exceed large work to carry? Cost how many? How does complex form spare parts hold clip? How to know the machine tool is processing waste product? Does repair spare parts hold the time cost of clip? How much is cost of machine tool dead time? The problem discovers in sampling observation, is other work quality reliable? Increase sampling observation density to want to cost of how many time and manpower cost raise? How does the product quality of each link assure whole treatment working procedure? When the spare parts needs check, waste of how many cost does machine tool backwater create? Be aimed at in technology of engine quality control character, need a machine tool to have not just measure a head, and need is had be aimed at detect the analytic ability of data, so the machine tool is had measure a head, whether to accord with is the level measured in machine check? The answer is negative. In machine detect want to have: Rely on the CAD model of the design, undertake data comparing is opposite do not breaking away from those who make theoretical model to detect, want to have a model to produce quality analysis at the same time, and can will among detect the result stores the online data in system of business management information collects a function, have perfect data to detect report, let data of CNC Machining process have but date from sex, OMv is to solve pilot of quality of CNC Machining process main tool, the quality control scotoma that makes up for workmanship of conventional numerical control, be short of annulus. In machine detect the capacity that data has output SPC data in the light of batch spare parts, detailed quality is offerred to dominate data in the course that produces effectively in spare parts quantity. In machine detect the technology is to be based on numerical control system to finish, detect by what PowerlNSPECT writes numerical control machine tool to be able to be carried out program, undertake colliding interfering checking. To numerical control machine tool character, its are main the function is used at tackling CNC Machining quality, the requirement cannot be done to the system transform, the code that uses itself of numerical control machine tool will come true in machine detect, output detect result, can support 5 axes machine tool at the same time. It is code of Siemens840D_ OMV part below: ... M80 C4 F2 M79 L_Output="G33O NO AO.

The article is based on Delcam to be in machine detect automation of quality of aerospace product CNC Machining, it is to be in utmost ground to reduce factitious factor, use digitlization method, the quality control that allows CNC Machining to make a process to numerical control from outfit clip is in a palm completely to accuse in. The development of CNC Machining technology is it is main show form in order to change technologist craft train of thought. Get used to processing technique oneself, same meeting overturns the transmission craft mode of go ahead of the rest of front jig of put into production of the spare parts in conventional technology, and use " make without clamping apparatus " machining complex, perhaps say for the number masked clip, intelligence holds clip. Here get used to treatment oneself just as its name implies is understandable for, to the work that sets arbitrarily on numerical control machine tool, be in through what numerical control machine tool has machine detect function, undertake detecting to the spare parts through digitlizing a method, obtain fixed position data, and according to the spare parts current condition adjusts CNC Machining program to undertake machining, this to complex, search without the tradition diagnostic spare parts has an advantage more; Additional, cast scraggly (need " borrow makings " ) , surplus is inhomogenous; Complex 3D spare parts, without straight edge / aperture department can offer search (for example: Forging blade; Model face part rehabilitate / solder the feature looks for) ; Repair and face-lifting, need searchs one part cannot from actual CAD model, need spare parts searchs through relevant curved surface; Large work on equipment shift searchs difficult part, if use,get used to processing technique oneself, can increase manufacturing automation capacity effectively. Automation of craft of the ala before some plane that has carried out with Delcam below makes enterprise battleplan and quality automation case undertake discussing. The ala before the alula face before battleplan wing is called or duck ala, the effect that the ala can have to a simple move or action operates and be balanced in that way like stabilizer before operates the flight state of the plane, like a simple move or action, roll etc, maintain a plane to shed medium flight to balance in faze take offense, can produce partial lift. In plane production process, earlier with can entering the space, ability of stable flight, motor-driven and basic function are main index, optimize demand as parameter of power of flying pilot time, of quality stability demand rise, need improves the workmanship of more crucial part. The quality automation craft of the battleplan wing that this case mentions is improved, be not the ala before this enterprise cannot make this in the past, be opposite however the demand of production efficiency and quality stability, control those who make a technology to rise as number, enterprise of our aviation manufacturing industry must give take seriously. To the case of craft quality stability of this battleplan wing, we undertake discussion from the means that hold clip above all, conventional technology needs to be this spare parts custom-built 3 special fixture, this spare parts is made should repeat outfit clip 6 times to just can be finished, and may put in blemish of the following craft: Workpiece is out of shape serious; The machine tool perhaps is processing waste product, and be not discovered, the quantity produces a spare parts not to talk to go up precision and consistency, stop machine, modification craft, efficiency low and wasteful many time; Many auxiliary outfit clip and clamping apparatus prepare; But maneuverability is poor; Very high production cost; Be not the craft stability of constant error. Improvement technology is to be based on plan to have " the standard can be duplicated " and begin the work: The spare parts installs clip to decrease; Decrease be out of shape; Digitlization is in machine detect and get used to a technology to let reject occurrence odds turn into oneself " 0 " ; High accuracy assures, consistency assures; Decrease and avoid to stop machine; Less technology measure; Reduce local treatment process; Considerably managing charge; Whole production process can accuse, and the operation that realizes STABLEPROCESS(stability handles process) . As craft automation is made and quality controls a system, have the following and main function: The spare parts date that defines work according to need above all and production information, have a spare parts to produce process control and quality but date from sex. Get used to machine tool of numerical control of treatment system program to detect oneself method, move on numerical control machine tool. Produce one each to get used to a result. Output one each to get used to treatment result. Undertake an analysis to result data, undertake the error is evaluated. Check a result, be outputted and suit oneself adjust CNC Machining code or parameter of numerical control machine tool. 3, precision of craft of numerical control machine tool detects (NC Checker) regards CNC Machining engineering technology as personnel, before write and arranging numerical control craft, to the craft precision of numerical control machine tool, whether to suit to process current work, our engineering technology personnel does not have most time such data, and place of tall accurate treatment must know these data. To this function the article is not done spread out discuss, do brief introducing merely, in order to offer reference of personnel of numerical control engineering technology. To going up in treatment program suiting oneself in the exemple, precision of numerical control bed detects use PowerlNSPECT NC Checker, can offer fast, handy machine tool and exploration system precision to detect method, can detect quickly and the moving state that report machine tool explores a system with its, with before begin, affirm the machine tool explores systematic precision with its, and because machine what if wear away,be run or cause,detect changes of any machine tool precision, for you treatment gives spare parts of high quality, high accuracy to offer safeguard and hope. Software applies to the commonly used machine tool with wide range in machine detect. 4, the last word is based on numerical control machine tool to be in machine detect of the tall nicety that the technology can have deeper person and quality automation extend application, in order to solve the crucial technology difficult problem of our aerospace manufacturing industry. The place on put together is narrated, have applied advanced technique to be in abroad, we can read extensively, more want fine concept, or from overall product terminal function looks for difference, from fine point hand, understand its to apply setting and domain to wait, the engineering technology staff that needs us to have rich aerospace product to make experience more at the same time is peeped to new technology and do not abandon, its want choose and person, take its essence of life and develop, from go up to rise our software tool to equip to have the software of bigger productivity at all. Informatization is much discipline knowledge accumulate, professional software solves professional problem, enterprise informatization much platform evolves is constant climate. Informatization environment includes enterprise ego development, commercial message to run unit of system, professional domain informatization system. And the article mentions in machine detect and getting used to processing technique oneself is unit informatization and the new technology of sex of the look up before having will have good applied prospect in future.
