"Do not talk, production spare parts " . Aaron Krieger describes the mood that a lot of clients when Krieger machinery company found in the Stuart of Florida before becoming him 24 years with this word. There is not overmuch dialog with design engineers at that time. In those days, the client hopes job shops can make a part only. Of course, mr Krieger also needs part drawing paper and norms watch to make his hand moves equipment to be engaged in machining production only. Nowadays, the workshop relies on CNC milling machine and machining center to make the client's part, but Mr Krieger thinks, the place of intense attraction is these powerful mechanical equipment not just. He explains: "No matter design an engineer to lie,design the where in the process, we can begin to make a part " . He says, this kind of flexibility and answering a gender is nowadays what clients go after. "They expect we can solve a problem. " no matter the concerned information of the spare parts is what form or format,this is meant, can effective ground and design engineers interaction. Sometimes, spare parts information is in CATIA, ProE or the hypostatic model with the complete good development that SolidWorks founds in such CAD system. And fall in certain circumstance, because design the period that data has not gotten to digitlization far when the spare parts, because this concerns the only source of spare parts information,be traditional blueprint merely. Sometimes, the spare parts is the idea in developer brains merely just. "We must reply such gesticulation " Mr Krieger says, he is compared in sky with forefinger delimited a rectangle. "They hope we are made give a such part, so wide, so long, be here and there have a few holes, " he is saying, and face empty middle finger point to. To realize this kind of flexibility, mr Krieger discovery needs a variety of software resource. The workshop has system of a CAD, will operate with it or establish the system of spare parts geometry of digital format. The workshop still has system of CAM of an off line to be used at creating machine program of G code spare parts. Finally, CNC milling machine and machining center own system of a few control, they offer conversational form on the machine tool inside the workshop directly programming. The geometrical body that systems of these double screen control still make the workshop can guide by CAD system place is founded, and run the spare parts machine program that by CAM system place creates. The agile, compositive method that develops KMC makes workshop nature formed it to be in the initial experience of CNC domain. What managing a workshop is original 6, in 7 years, the technology that Mr Krieger regards a skilled machinist as to rely on him will handle the work of the factory. But, to 20 centuries when 80 time metaphase, he discovers change is machined into CNC is only outlet, only such factory ability continue to live. Fortunately, he found a kind of method, make he can think already like machinist in that way, and be opposite smoothly process designing of CNC machine tool. The answer is system of conversational type process designing, it uses a kind of intuitionistic logical pattern to enquire the information of concerned spare parts. "I know how to must machine a spare parts, " Mr Krieger says. "I can see this in the brains in me. Conversational type process designing helps me put this pair of picture to control screen, here, the picture will turn the CNC that machines this spare parts into machine program. " Mr Krieger thinks workshop process designing can make CNC operation is carried out successfully in its workshop self-confidently, he 1983 from Hurco company (the indiana that is located in an Indiana Bolisi) bought milling machine of a KM3-P. This machine tool contains system of process designing of conversational type of an Ultimax II, the system has Shuang Bing. A screen shows choice and treatment options, and the 2nd side by side the choice that screen criterion hints to place make answer, show body of spare parts geometry and cutting tool way according to the definition. This machine tool moves successfully. The 2nd machine tool was installed after 1 year, it mixes the first almost exactly like. Later additionally 3 machine tools were installed again in 5 years. These 3 are the machine tool of machining center of Hurco BMC 4020 that contains Ultimax III or IV system completely. At this moment KMC built workshop of a CNC completely already, the career is flourishing rise, reputation is better and better, become electronic instrument, reaction engine and medicine to produce business reliably into a when resemble an industry, it can provide preliminary prototype / development component, initiative fare is low, be engaged in high quality for a long time producing the job. Software resource increases CAD and KMC of CAM system help to retain this kind of power. The main CAD resource of KMC is from Kubotek USA company (the Moerbaile that is located in city of Ma Sazhu a place of strategic importance) system of bought a KeyCreator. This CAD software is former of the is based on PC CAD software of Cadkey be callinged upgrade edition. Invited John Goings to help last year when Mr Krieger when he manages a workshop, introduced this CAD system. Mr Goings once was the business manager of a of this workshop long-term client, the experience of associate with makes he is familiar with KMC very much. Mr Goings still is being made and respect of CAD application software has very solid cultural background. His CAD knowledge especially useful. CAD software makes the workshop can operate the geometrical system of almost all format, include 2 peace keeping model of three-dimensional line draw a frame round, scale model or hypostatic model -- the general pattern that carries system of spare parts geometry at present. The system of spare parts geometry that becomes a client is sent to send KMC(is normally when passing Email) , mr Goings opens it in KeyCreator, change its into primitive form of the system. At this moment, he and Mr Krieger analyse this geometry system together and machine strategy basically certainly. This strategy is to cite the foundation of the task. John Goings checks 3D hypostatic model on CAD screen, the treatment that is used in order to develop at spare parts production is politic. Repair any blemish in geometrical body or mistake at this moment, make its useful to machining application software. Same, the tagging that uses CAD software dimension and scale draft function, also can founding 2 dimension blueprint easily right now. The main CAM resource of KMC is CNC Software company (the software of a Mastercam that the Tolland) that is located in Kangniedige provides. Mr Krieger bought this software 2002, advocate if be curved surface of batten curve, NURBS and body of other and intricate geometry because of it,such workpiece offerred process designing to support. In addition, his discovery needs offline CAM system, so that one part the heavy burden of 3 axes process designing is transferred from machine tool cutting tool. Because the control system on CNC machine tool accepts file of G code spare parts, because this this CAM software makes a workshop OK,more agile ground assigns process designing task. Most CAM process designing wants the geometrical system that guides one is offerred by the client above all, its format is STEP, Parasolids, ACIS or IGES file. Guide data avoids to rebuild geometrical body perhaps appears data input is wrong. This simplified to generate cutting tool to machine the process of method. The G code document that produces finally passes disk or reticle is transmitted machine tool. Although CAD and CAM are value,do not poor and indispensible software, but the foundation that Mr Krieger still thinks the function of control equipment of machine tool tool and workshop process designing just are flexibility of its workshop treatment. "Conversational mode is the quickest way that makes the spare parts enters cutting process for the workshop to us, " he says. Pass with certain hope " gesticulation " the client communication that produces prototype, this is this option offers a instantly the example of process designing. More important is, workshop process designing is helpful for routine. "It makes we are editing, revise and optimized respect of spare parts machine program to obtain the biggest flexibility, " Mr Krieger says. He says, we admit the design change that the client poses easily. For example, "Data piece is searched " the proper place that the function conduces to fixed position must inputting new data to be worth where. Use workshop process designing, we need not return CAM system, edit machine program and use tiring-room processor afresh. Need not manage the many version of machine program of a spare parts carefully. Newest version is that one machine program that saves in the memory of machine tool control equipment from beginning to end. The length of G code program wants like the length comparison of the machine program that establishs through conversational mode many short, accordingly more be saved easily and transmit. Finally, mr Krieger report says, because pass the cutting tool that conversational mode prepares to machine the accuracy classics of the precision of method and machining center to confirm,be quite reliable, so his workshop is done rarely try cut. The cooperation between synergic CAD, CAM and workshop process designing helped KMC assume the job of a new client recently. The spare parts is the case that an aluminium makes, have case of a small tobacco about so big, enclosing the printed circuit that is used at controlling plane electron system board. A frame around in 4 outside side, it allows this crust to be installed directly go up in an appearance dial. What the interior of crust has a lot of chamfer and bore is fixed, they hold circuit board stand with Yu An, be built before join and operate face plate. "For contest mark this project, we got an example spare parts and blueprint of a spare parts, " Mr Krieger memory says. "When examining all geometry body inside crust with me when John, we discover this will be the project of sex of a quite rich challenge. " a hypostatic model that the blueprint that Mr Goings consults the client is offerred established whole case in KeyCreator. Hypostatic model allows two people to rotate and watch this geometry system from different point of view, such they can understand how this geometry body " break up " the independent part that becomes OK and separate treatment. They discover the extruding aluminous semifinished product that uses off-the-peg standard measure can reduce waste, make lowest of cost of material. Can assemble these parts into a complete work next. Mr Krieger suggests to use spot welding to assemble assembly parts, undertake aluminous immersed solder in the spot next. This aluminium makes electronic instrument case come out through assembling a spare parts to produce, these spare partses are to serve as 6 alone workpiece (if the place in illustration is shown) come to those who make machine. The option of agile process designing of the workshop makes KMC can refer sample quickly to win order to be based on this kind to create strategy beforehand to the client, KMC was referred bid. This price that bid is very competitive, aroused strong interest of the client, but they still have a bit concern and such new, contractor signs unfamiliar contract. "We think to send the sample spare parts of an ourselves may capture this business, " Mr Krieger says. Two people of Krieger and Mr Goings give him two weeks time a future life produce sample, include 1 week turnaround time to undertake aluminous immersed solder among them. This is meant all component should give in the treatment inside 4 days, keep the production with current workshop. Use the spare parts model in CAD, mr Goings machined working procedure to make alone file for every. For example, of every side panel exterior it is a working procedure; The interior of every face plate (rear) it is another working procedure. Mr Krieger relatively simple outside process designing of workshop of admeasure of side treatment component, the treatment of in-house geometry body with a more complex, taller repeatability gives CAM system. Mr Krieger assumed the job of workshop process designing, allocate CAM process designing to the Shuford Swift of main Mastercam programmer of KMC. "On Hurco, body of my general geometry guides with DFX file format on a screen, begin to follow next clew builds cutting tool to machine method below conversational mode, " Mr Krieger explanation says. "This makes I can select the certain part of the geometrical system that is called below clew, and need not a line a paragraph of a line, arc of a paragraph of arc rebuild model. " the result that entered appropriate geometrical system to also achieve similar spare time through guiding on CAM station. As a result of the flexibility of machining center control equipment, operation of the first pace passes conversational means generation on a machine tool, and operation of the 2nd pace undertook process designing in Mastercam, move with G code means on another machine tool. "This makes we produced such opinion, if we win this job, can found many working procedure to be used at production to run so, " Mr Krieger says. System of workshop process designing makes KMC can found a model easily to repeat or replace machine program, in order to match many parts process. "This kind of action is tremendous, " Mr Krieger says. "It makes become flowing to manufacturing changeover from tectonic prototype much, fast much. " after been machine when all and separate spare parts, interlocking edge makes the lid before 4 side panel and appearance cooperates cheek by jowl together, and exterior frame slips another end. This design formed a substantive case, all detail part already also had machined its inside and outside, all gets ready undertake spot welding. "When we submit sample to the client, left very good impression to them, " Mr Goings says complacently. "We won this order. " the value that realizes a technology to Mr Krieger, can share production technology, is to sell man-hour not just, the life that this makes he regards job shops as owner is more significant. With the past " do not talk production spare parts " times photograph is compared, with the design engineers cooperate each other and give effectively answer, this makes us OK now more satisfactory use skill and experience. The key is to use treatment and software resource to blend in idea in the spare parts. This makes the workshop can add all difference to the middle of data value, mix when creativity especially when productivity is euqally important. CNC Milling
