Graph 1 workshop interior is very neat, bright, provided a very easy work environment to the treatment of the machine tool is produced and operate personnel now, leinishao (the method of innovation technology control of Renishaw) company already was in its " new " inside workshop, through the production of innovation control method got be strengtheninged further. Company of Lei Ni carry on is the metric system manufacturer of an England, be in early 20 centuries at the beginning of 90 time, developed mill of car of carry on of RAMTIC(Lei Ni to examine center) system and its distinctive technology control method. RAMTIC system first when face city, its have two apparent development characteristics in domain of actual machine tool technology. One of, used portable revolving stage coming back namely, the tray that is used at workpiece and cutting tool is changed deferent. Another characteristic was to use man-made example or example cell, adopt these model, the machine tool can examine automatically and have the measure desired result of oneself. The focus with RAMTIC the most conspicuous system depends on its manufacturing function, before and be being referred to the workshop be being produced, can thoroughly test and verify its all technical properties. Place of no less than introduces in that way, RAMTIC system can let what this company uses a level mix the VMC vertical machining center with relatively inferior charge, in order to reach the treatment precision of certain level and automation level. 2006, this company installed new treatment facility inside the workshop that the course transforms in the round. All small-sized and nice spare partses are machined inside this workshop, later this factory according to the house of stone of a village near seat (Stonehouse) names for its. Its purpose builds the most advanced machine on the world to achieve its namely one of job shops, this is very crucial one step. Company of Lei Ni carry on needs to enlarge its productivity, so that apace catchs up with the speed of its product development. This company hopes its much product is produced in England, ask domestic factory can reach as identical as other area production efficiency and economic level that is to say. This factory is after put into production, appeared a few problems. Whether does the RAMTIC system that has had 15 years of life still have energy, can they find themselves in new plant " position " ? Whether is this job shops still using revolving stage coming back and man-made model? What institute of new plant of no less than behaves is same, how does the manufacturing concept of company of Lei Ni carry on get carrying on? The answer is affirmative of course. Over, RAMTIC technology got tremendous progress. The fact proves, producing an idea can continue to carry on. RAMTIC technology has very tall automation productivity and reliable technology control level. Example of combined-type rotator, man-made and screw device still is used in routine. And more important is, concerned craft sex and complete craft test and verify design a principle to be being applied by more extensive promotion. Actually, they are the two big main pillar in producing control system at present, can rise to control function in whole factory. Company of Lei Ni carry on calls this kind of basic method " system of productivity of Lei Ni carry on " . RAMTIC system can regard the craft that is the application in level of machine tool grade to control example, and yield system can regard bigger Leinishaosheng is foundation of pilot of craft of effective inside factory limits implementation. Graph 2 need are mutiple level the production of technology control ability of in an orderly way gives accurate treatment part. Of company of Lei Ni carry on " craft pyramid " make clear, technology control must be built firmly on DFM foundation, and should get the support of stable workshop environment can see from stone house factory, use intelligence to change strategy, and pass strong execution, any manufacturers can make their production maintains go up in due level. The main reason of system of RAMTIC of RAMTIC system development depends on 20 centuries when 80 time, job shops does not have the machine of company of Lei Ni carry on air conditioning equipment. At that time, the environmental temperature wave motion inside the workshop is bigger, together with machines the quantity of heat that the machine tool place with not stable condition sends out. In the meantime, this company tests the demand of the instrument to rise quickly to bougie. Apparent, this company still needs to raise production and craft automation level. Then, the project technology personnel of company of Lei Ni carry on developed a kind of integrated measurement technique, in order to solve the problem of existence. But at first, as a result of the influence that is changed by the temperature in craft, and the obstacle that encounters in realizing automation process, this kind of effort did not succeed. Then, this company begins to explore a kind of new strategy, passed effort of a few years, manufacturing operation was on right way gradually. The reform innovation of craft must be mixed from the design of the project think set out, answer to be contacted cheek by jowl with this. For example, engineers begin an edition " manufacturing design manual " , build and communicate the most effective practice experience. This manual is occupied according to foregone all computation, the treatment technology that practices the course test and concerned spare parts character edit together, form the database of spare parts character of a standardization. Actually, do the effectively Suo Dingsheng in can designing a process to produce technology so. During this, this company begins to use automation line exercise and automation treatment technology. In the meantime, engineers begin to seek the means that solves a few problems. For example, developed portable tray revolving stage coming back, the workpiece that regards VMC vertical as machining center assembles and unassemble automatically means. Clamping apparatus of unified swallow end chamfer not only can hold calorie of many parts, satisfy the need that spare parts polyhedron machines, and still can install the tool carrier that includes many cutting tool. Accordingly, this kind of revolving stage coming back can supply all sorts of requires cutting tool and part. More important is, this revolving stage coming back can shed regulating system as a job, balance the workload in technological process, return the requirement of respect of can contented inventory at the same time. Much work clamping apparatus can install a series of workpiece, be just as " workpiece reserves box " . The main part that assembles whole product place to need is included inside every workpiece box, the signal that spare parts box issues according to system of this company MRP is classified. Accordingly, revolving stage coming back is become offer " batch workpiece " device, its amount often with demand order goods the quantity is synchronous. When revolving stage coming back once berth is on the side of the machine tool, the work that handles personnel announces an end with respect to of short duration, until till the treatment of all spare partses is finished after 25h. Result from the newest invention of RAMTIC project system compares a skill for man-made example. Man-made example namely example component, they can machine a characteristic on behalf of a series of average machine already, be like groove, aperture and protruding stage; Also can represent the duplicate of specific work. No matter its attribute which kinds of kind, man-made example and treatment material have same heat expansile. What man-made example installation uses in spare parts and cutting tool is same a clamping apparatus of swallow end chamfer go up, the stage conveys and can exchange through rotating. Man-made example is in before depositing a machine tool to go up, need surveys machine captain test in CMM coordinate. Man-made example can make the workpiece of the treatment on the machine tool or structural member get heating up bulgy compensating. In addition, it still can let measure on machine with dog the join that measures a level is together. Because have this two big advantages, it makes the automation test and verify on the machine tool became a possibility, the handiwork that because this does not need,has costly take time again later in treatment examines. Need of this man-made example uses bougie timely on the machine tool to detect, have the measure of detected result and desired result comparative. All error that always cause apparent error likely can get automatically compensating. According to the view of this company, introduce a common man-made model, can be control of craft public errand in 50µm. If introduce specific workpiece man-made model, can be tolerancepublic errand control in 20µm. 1993, RAMTIC technology is applied on 4 machine tools by comprehensive ground, achieved expectant result by the plan, include long-term nobody turn an operation, dimension public errand maintains in micron grade level, treatment cycle shortened 50%~75% . 1995, company of Lei Ni carry on operates its machine treatment business to remove a new plant of air conditioning, new plant is located in the New Mills headquarters of area of Gloucestershire county Wotton-under-Edge. 7 RAMTIC unit system was installed when new plant start business. In 10 years of after this, new Mills new plant upgrades continuously and expand, there already was system of 19 RAMTIC unit to throw production before stop production. However, arrived 2004, new Mills factory already can install more machine tools without redundant place. But, this company still hopes to develop new industry further metric domain. This produces the part of large quantities of quantities in the round with respect to need, and add spare parts variety. In addition, this company need promotes finished product inside shorter time to the market. Accordingly, returning need to build a new plant soon. After having careful consideration to a few kinds of plan, this company decides to purchase an off-the-peg large factory building, transform the interior of workshop neat, ventilated, agree with the workshop that machines production. New factory building is former it is manufacturer of a model that note model, from Leinishao company headquarters makes an appointment with a few miles distance. There is a bougie to detect in hand of graph Mr 3 Paul Maxted device, used this kind of bougie to detect on a lot of machine tools of this job shops factory of device stone house besides neat and bright besides, the stone house factory building that the course transforms is very capacious. This factory 2006 practice, cover an area of 9300m2(100000ft2) , among them 6500m2(70000ft2) is machine job shops, another 930m2(10000ft2) eletroplate as the finish machining of the spare parts and positive pole workshop. Here produces 5000 kinds of different parts about, the spare parts total output of every month is 400000 about. Be in stone house factory, RAMTIC system remains Leinishao's fair driver to machine the skeleton force of the operation. RAMTIC system applies at one goes up by the 28 Mazak AJV product line that forms with FJV machine tool. These machine tools were passed transform, the main transfer machinery that includes one apply mechanically to be exchanged at clamping apparatus of tray of swallow end chamfer among them contains the index mechanism of triangular base with, horizontal land installation is between the center (comfortable machine) at 3 undertaking on tray. Present revolving stage coming back uses whole sealing structure, but its interior construction is basic and identical. Same, man-made example still has crucial effect, but heat is out of shape compensation already became his no longer main function. The environmental temperature control inside stone house factory building is in 2 ℃ of ± (3. Inside 5F) limits, be close to the cooling fluid temperature that uses at the machine tool. Machine tool place has character of the buy inside some controallable main shaft and the fuel factor that guide screw produces. Quantity of heat can produce certain effect admittedly to the motion of the machine tool, but this kind of effect is opposite for not quite apparent. Through rebuilding crucial data nods the position and newer job coordinate, can dog of bougie detect the course eliminates his to affect. This kind detects is the ongoing travel of new on treatment tray work. However, man-made example provided a basic link to come from the foregone precision standard of the machine tool. This kind but the characteristic of date from sex makes the check test testimony on the machine tool becomes a possibility. Man-made example also can be helped reduce metrical uncertainty. Man-made example needs to use bougie to detect on the machine tool regularly, the size that measures dimension and CMM coordinate machine captain check undertakes comparative. Any errors that detect can serve as a coefficient of proportionality, correct the other measured value that produces on the machine tool. To project technology personnel character, stone house is a very good plant. There are a lot of apparent differring between old plant and new plant, this to them it is a rare opportunity. Its markeddest characteristic is: The machine tool sets hub: The supply that these this locality change all sorts of cutting tool that the center can provide place of machine tool periphery to need, debug install and examine equipment. Collect Chinese style cuts bits deferent system: A large number of aluminium that produce in high speed treatment cut bits to be centered in to reduce a system character inside, cut bits to be able to pass trash loop device to reclaim through dry lump use. Prepare an area through transforming the raw material that upgrade: Numerical control is cut off curium and an automation goes the wool blank after burr workstation will be handled sends in time toward configuration area. Such, the wool blank that handles via past burr can be on clamping apparatus secure take one's place better. Project technology and workshop staff member contact cheek by jowl: The seat that produces project technology personnel is close to job shops more, be helpful for communicating each other with operation personnel. Spare parts water cleans workstation: The spare parts can discharge a standard to be cleaned quickly according to strict dissolvent. Dynamical pyramid is designed about production (a few comments of abbreviation DFM) and the workshop environment that stabilize continuously give enough sketch this tremendous picture. Since start business of stone house plant since, DFM had entered his development period truly. In the old machine of New Mills factory job shops is used to now the treatment technology with the production of spare parts of test and verify and new development. All machine tools inside stone house factory are OK undertake duplicating according to the machine tool of New Mills factory, use same machine tool and same condition. Manufacturing engineer can be here all sorts of documents that development, test and verify and work out process about new part, include to divide the process designing of design of analyse, clamping apparatus and numerical control system to cutting tool from cost choose, try move to study with the function. Same, the technology that always did not incorporate in DFM guidelines needs to have a test here, add a database again next in. When a new part needs go into operation, all manufacturing problems had been solved entirely. Ni Shaogong of thunder of no less than manages production serves place of department general manager Mr Gareth Hankins to point out in that way, DFM is the best opportunity that gains economic production, because be in design process, the much that affects product cost is decision-making already made. Accordingly, the much of company of Lei Ni carry on produces an engineer to concentrate their energy on DFM now, this do not make a person strange. In the closest production the operation runs a course in, only a third party supports his to operate, the circumstance in the past is not such. In responsibility respect of the staff member, the key also produced similar change. Now, their main responsibility is being produced centrally " pyramid " intermediate part. The production of major job shops is begun around the operation environment with stable move, is not to be centered on treatment craft. The system of these high automation basically is to move automatically, if resource change cannot get constant pilot word, they cannot achieve stable and consistent predicting result. Establish new standard, have best practice and carry out be special key strictly according to the standard. Personnel of machine tool operation must list beforehand " the examination detailed list before the job " , should mix by examine and verify of a superintendent sign. Before beginning production everyday, assure to have proper examination through this detailed list, and finish defend the work daily. CNC Milling
