-- the automation measurement technique that uses a kind of innovation, will help solve much machine tool flexible the problem with manufacturing environment inherent place 2008, kurt production company installed an automation to produce a system in its Minneapolis manufactory (APS) . This APS system and treatment unit whole set throw production, the spare parts that enters this system treatment is a course beforehand the cast of spray paint, when leaving this system, already made the component that has assembled. Strategy of its very will effective tool clamping apparatus and advanced and complex measurement the system is united in wedlock together, all sorts of variable that effectively control machines the place in the operation to appear in APS treatment, heat treatment and grinding. Make the statement of limited company according to Kurt, people takes the height of tool clamping apparatus of its Anglock brand seriously, it is the precision that is based on them and wear well sex. Because,be this reason, this company claims, 50 come for years, these bench clamp make this company's best-selling product all the time. Measuring is one of crucial factors that Kurt company automation produces a system to score a success. The form of bench clamp casting that processes without nicety is like picture place to show, this is this cast use in a grinder of automation system assemble and unassemble automatically this company also understands the treatment situation before workpiece, this kind of product is sure have very strong price competition ability. High grade bench clamp, very good price, it is to make win the home to hold leadership position and the key that boycott the person that abroad low is modelled on in the market. Whole set investment produces whole APS and treatment unit, the spare parts that enters this system treatment is a course beforehand the cast of spray paint, when leaving this system, already made the component that has assembled. This APS system has height inside buy automation level, can 24h keeps moving, need artificial interpose rarely. If the spare parts short of is necessary quality standard of place production, so use automation production to also be without a meaning of course. For example, the flatness of bench clamp component and parallelism must accord with close together tolerancepublic errand dimension to ask, this is two crucial quality index, although use very perfect manual technology, want to achieve this one standard to also be not easy thing. The flatness that the design of APS already was achieved or exceeded place regulation and dimension of parallelism public errand ask, change in nobody / below the circumstance that works without lamplight, also constant maintains its normal productivity reliably. System of this one APS is overall decorated a graph to show configuration of L of this system blazing layout. Can see from the picture, grinder of plane of numerical control of two Chevalier CNC is arranged to be in assemble and unassemble at the back of workstation. Machining center is located in the left of setting to reach the view of personnel of its project technology according to the design of Kurt company, want be complete likelihood to achieve this, strategy of effective tool clamping apparatus and advanced and complex measurement because of APS the system is united in wedlock together. Their combination, all sorts of variable that can control the place in the operation is being processed with grinding in APS treatment, heat treatment effectively to appear. The component of Anglock bench clamp of 8 kinds of different type and different measurement, machine processing on APS, they accord with flatness and the test requirement of parallelism entirely. So, be what makes its scored so extraordinary success after all? It is much machine tool flexible the diversification that produces a system is substaintial. Say simply, a variety of operations of much stage machine tool can increase the opportunity that creates an error necessarily. The position that Docklock pneumatic a powerful person locates the system is in, reach its how to be locking of body of casting of each bench clamp over grinder. These working measure by measure systematic monitoring " use this to plant muti_function the system will achieve taller repetition precision, the challenge that its face is: The treatment processing of body of any casting of specific bench clamp can adopt a variety of likely producer form, " report of manager of department of Kurt industry product Mr Jeff Lenz says. "For example, the body of bench clamp casting of a kind of specific type, in can using 5 treatment tray among them, it is on an any machine tools of 4 horizontal machining center undertake machining. This bench clamp also can stand in two heat treatment among them one has heat treatment, can be on the any tray of 6 tray, and be versed in in 6 grinding among them one undertakes grinding is machined. Use a variety of likely producer formula, use appropriative measures clamping apparatus of system, tool and SPC software, its flatness and parallelism can achieve our goal. And afore-mentioned all products that these things are Kurt company. " system of NextpageAPS dekko APS is conspicuous because of its blazing mixture design. This system uses L position, among them L long leg part by a Mazak Palletech FMS (technology of campstool gram tray is flexible manufacturing system) composition, be linked together with 4 horizontal machining center all round its receive. Tray technology lades twice of the station among them one is managed by a robot, this robot also is to be mixed by workstation of a two planar grinder, heat treatment machining center of one Taichun vertical comprises " branch line " provide a service. Although system of this tray technology belongs to the device that the standard comparatives in this manufacturer technology, but this branch line is however develop by Kurt company among them a configuration, use at be opposite machine the accurate treatment that adds workpiece. And other something makes APS and any other flexible manufacturing system unit differs somewhat, its designed the range of products that is Kurt him company to create to reveal a space distinctly. Unit of the Kurt tool clamping apparatus that project technology personnel uses a level, tool fixture that designs technically, Docklock and other project system and this one treatment assembles form a complete set. In fact, the treatment with effective tool stable to assuring, high grade clamping apparatus; Reliable robot assembles and unassemble; Attemper neatly the demand that arrangement produces with satisfying a product to mix; It is very crucial to all sorts of compositive combination that manufacture technology. On the system among them a monitor, showed body of bench clamp casting reading of apparently dimension of 28 public errand is same, what crucial grinding machines operation criterion to be developed by metric branch of this company Kurt Gaging is special measure systematic place control. This one system uses the SPC software of this company. The core part of this system is a when its interior is designed and build metric workstation. When the primitive cast when bench clamp enters phase of final finish machining grinding, this are metric the station can is opposite each operation of body of bench clamp casting undertakes a series of measure, monitoring each craft (include heat treatment and machine treatment, grinding treatment) , need not change among. "When body of bench clamp casting secures the treatment on clamping apparatus, a series of LVDT probe will be right peace of the flatness of this spare parts, ply is spent all right undertake metrical. This one process needs the time of 30s about. This are metric device will offer concerned measurement data, include the overall length of body of casting of this bench clamp, because this system operates personnel,complete understanding spare parts is in those who undertake each operation around is exact measure data. " Mr Lenz explanation says. The APS system that leads by SPC system by quality of SPC software monitoring, Kurt SPC Premium and Manager manager software are full automatic change computerized numerical control of machine tool, CNC and automatic data to collect provided interactive function. Check looks up grinding craft to be able to see this software is how to manage machine tool and other equipment, and how does the other measure in processing unit with APS system interact reach how to deliver consistent result. The grinder of plane of numerical control of two Chevalier Smart B246011 in APS, can machine processing to amount to 60 kinds of different bench clamp configuration. Maintain all measure that these differring to ensure exact location is mixed, locate in the Docklock pneumatic that Kurt company equiped on tray system. This system is sold through locating 4 at 0 o'clock make its secure the bottom in each tray, these fixed position are sold spark by bedspring fixed position, make tray is secured, release them through enraging a powerful person next. According to the view of this company, the fixed position precision that fixed position sells maintains in 0. 0002in (1in=25.
4mm) in limits, and the air cylinder of Docklock can lock up body of bench clamp casting closely calm, undertake grinding is machined in order to facilitate. The process of the fixed position that finish and locking needs a few seconds about. Of every grinder bear board can carry on amount to 3 tray, this wants a basis to the dimension of body of bench clamp casting and operation ask and be decided. Contact measures probe to move locally in the many keys of body of casting of each bench clamp, determine its height and require grinding amount. Apogee and nadir are found on the casting body without finish machining, the finish machining that is grinder is automatic process designing, arrive in order to make once be laded by the robot when tray,its reach the most significant operation level when the lathe bed of grinder, after be being located by Docklock positioner, a metric head is met automatic perch, test and verify the position of each tray, detect the height of body of casting of each bench clamp. The fixed position that measures tray to go up quadrilateral through electronic means sells height and this is finished. This one process is for test and verify whether tray is aimed with workbench lathe bed, and likewise important is to check its to whether be put in any laden problems. The purpose of height of test and verify, it is to decide the grinding that place of body of casting of each bench clamp needs is measured. If height and load capacity are incorrect, the robot will try to undertake locating afresh to tray. If new fixed position did not win a success, tray general by repatriate, spark at the same time the orgnaization is given out to systematic operation personnel call the police, so that take corresponding step. The design that measures a head should bear quite abominable grinding machines an environment. The existence of cooling fluid and greasy filth should be not affected measure an operation or affect its to measure precision. Grinder and measure software and KurtUSB are collected to measure head interface hardware to undertake contacting directly through SPC data between the head. The measurement of the spare parts data starts with what grinding machines / stop dimension to will be passed to send grinder to control a system directly. After finishing each grinding to machine cycle, the measurement that has installed beforehand head general test and verify is final these precision that machine craft. (the precision for measure and master whole measure a process, in predefine and programmable cycle, use an independence to come at the fixed pin of grinder tray test and verify and the circumstance that master measure) . With installation APS the circumstance photograph when before is compared, use SPC software to control grinding to process an operation, can make machine periodic time to shorten 30% . In fact, the exercise of hand tool discharge previously already was washed out, need not latency time, this one word is done not have count this one latency time inside. The collection of data and analysis are collected in the data that passes a few weeks later, this company can identify the area that gives existence issue, the metabolic element that causes because of clamping apparatus, tool and other issue place through eliminating thereby, raise craft level ceaselessly, mr Lenz report says. "Data is collected in much data when us when, we established a kind of distributinging plan that contains a few mode, the technology of a kind of above is used in suggesting to be occupied in this. For example, the sign that data showed every horizontal machining center and every grinder to wait. " Mr Lenz continues to say: "Our measurement is installed ensure we can produce the system of bench clamp casting with a very stable quality, no matter APS processes unit,medium machine tool, clamping apparatus and tool system use what kind of combination. To optimize craft further, if appeared problem, or the feed speed that we get on in tool, clamping apparatus and machine tool made change, we can analyse our easily the effect that opposite produces. " before APS is installed, treatment of the heat treatment that Kurt company uses a convention, machine and grinding treatment unit will produce its bench clamp. Operation personnel must be passed groom specially ability is finished measure an order. The software that Mr Jon Baller is group of Kurt project system develops a manager, his memory says, the job is being measured previously is a slow process. It depends on the change of personnel, an operation personnel and another operation personnel differ somewhat, and each production number also differs somewhat, accordingly, keeping stable and high grade is a very big challenge, he says: "When we design new APS, its target is to use electronic means of precision of treatment of real time monitoring and each technology measure but date from sex. We had achieved this one goal. And, we used our labour force effectively. Now, we need 3 operations staff only, and old manufacturing system, we need 5 operations staff. And, new system upgrades very easily still, because we are in,carry on mix to order goods and increase order goods quantitative respect ever had experienced more change " ask an attention, this are new the system has a lot of advantages, one of the mainest proposals that Mr Baller offers are: "Build to agree with the large system that our bench clamp produces, make we can have an opportunity to show our ability. " in the final analysis, this kind of advantage has very important sense, because it was our company to provide the tool that its need, in order to hold the quality that its compete in global market and value.
