Already produced the market of fundamental change to suit, manufacturing industry is developing the product that has higher additional cost energetically. In product development, the effect that measures a technology appears increasingly important. Be in at present nicety is metric detect domain, measure precision to already measured class to develop accept rice to measure level from original micron, to appearance of more imperceptible treatment detect also be paid close attention to by more. Not only be like surface roughness of shape size, surface, circularity to wait to the precision quality of the product put forward taller detect requirement, and use all sorts of detecting at what test and verify machines precision of machine tool itself the technology also is in ceaseless progress. It is never-ending that quality management produces a workshop to machine efficiency and the pursuit that reduce finished cost to rising to gauging technical demand. But, the most important is to improve product quality. Accordingly, use strict level, execute proper quality management crucial. As the method of quality management, the component as using high accuracy group make treatment machine tool and high accuracy is deployed to measure on product line machine in that way, need builds product line a kind " self-discipline " system. Can forecast from this, will be needed to detect to quality management henceforth equipment and the demand that support a system will increase further. Producing the spot actually, use gauge will detect the product still is the mainstream detects up to now means. Gauge is to be aimed at the special measuring tool with all sorts of custom-built products, do not have hold the versatility that is used at other component concurrently, if the design of component produces change, be redesigned with respect to need and make gauge. Be opposite as the market the diversification of product requirement, the sort of component is increasing ceaselessly, make the amount of gauge also increases subsequently. In addition, the craft with the making excellent need of high accuracy gauge, as the replace replacement of skilled worker, buy high accuracy gauge very hard already now. Passing what gauge obtains to detect is a spare parts merely as a result eligible, whether enter below one process, and the real measure cost that cannot be measured and records a part. Accordingly, the measuring instrument that can be used at producing the spot implement times get attention. Measure an instrument through introducing the spot, can be collected and accumulate measure data, apply these data feedback at machining flow. In addition, through building a database, record and save measure data, when as end item in component work off hind produces the problem such as quality blemish, can mastering this component is to be in when, machine where, have namely but date from sex (Traceability) , search easily also reason and solve a problem. But on the other hand, measure an instrument to measure the raising of precision as the spot, the environmental suitability to the instrument, dependability and detect efficiency also raised taller requirement. The domain is measured in nicety, be used at quality management but means of thinking of date from sex and the value that assess uncertainty of measurement already achieved extensive consensus in manufacturing industry. Evaluate as run-of-mill measurement, forming research to discuss precision to trace to the source the environment with uncertainty of measurement. Trace to the source by precision and do not spend the to measuring dependability assessment that form certainly, formed with ISO (international Organization for Standardization) standard system runs a system for contemporary quality of the representing. The management of dimension can say is production main essential factor. Henceforth, as the development of overseas production foreground is valued, ask the high accuracy component that produces in different area has interchangeability. In the process of globalization, it is large company not just, include small and medium sized business to will take seriously more and more even be based on international the product production of general measurement technique. New knowledge product line is online metrical value, discussing complete quality management method just is the powerful weapon that surmounts globalization tide. Right online the user demand that detected demand produces to satisfy ceaseless pursuit high accuracy, low cost, the requirement is measured the instrument can machine quality for the examination not only and undertake dimension is measured (measure quite) , still can come true online detect (or measure instrument installation to be by product line, facilitate of the workpiece that be measured assemble and unassemble and carry) . Detect in the appearance of car component respect, use real time increasingly to detect workpiece will detect as a result seasonable feedback winds the way such as treatment flow, online detect present a driving development trend. In production the spot undertakes detecting, need satisfies the following requirement of the user: ① improves manufacturing efficiency; ② raises the dependability that measures an outcome; ③ gets used to the harsh environment that produces the spot; ④ satisfies the installation space of measurement unit to wait. These requirements basically are based on automation, unmanned change metrical requirement. Correspondence implements quality management and the need that build product line at the user, each measure equipment manufacturer to already will be offerred for specific user about detect the solution of the problem serves as main development strategy to give carry out. Make online detect the key of the solution is to be used at what monitoring machines flow to measure a technology to whether can match appropriately with treatment facilities. Use closed circuit (Closed-loop) the means cutting tool that monitor and the quality that change knife system to will raise machining and efficiency, reduce manufacturing cost substantially thereby. Online detected purpose is maintain and improve treatment, assembly precision quality and manufacturing efficiency. At present the enterprise takes will original product line changeover seriously to reach the efficient product line that produces high grade product steadily to can improve the treatment, performance that assembles a system very, special need is accordingly online detect technology and the support that measure equipment. The demand Marposs company that surveys to automation puts forward the earliest and applied contact and blame contact measure a technology development is online and measure from the line machine. This company measurement a lot of standardization component and the package need according to the user undertake assorted custom-built, in order to get used to all sorts of treatment machine tools (like grinder) undertake to work measure pilot asks be metricaled automatically mixing. As package solution, marposs company still developed correspondence to be measured at the size shape of all sorts of grinding machine tools, sound blasts off monitor and quantity of oscillatory, grinding survey a system. According to saying, this company already received the order of solution of a lot of systems and large order, show exuberant market demand. In recent years, measure precision to what appearance precision measures an instrument the requirement is strict with each passing day, to small hole and tiny part gauge demand also increasing continuously, the new product that satisfies this kind of requirement is being come out by development ceaselessly. For example, of Taylor Hobson company exceed nicety to be not contact three-dimensional face figure is measured machine the special algorithm that Talisurf is based on this company to win patent, use interference stripe to determine resonance peak value and phasic position, can with very tall measurement speed is mixed high resolution (0.

1 dust) the high accuracy information that gets the sample that be measured. The resolution of the instrument and measure precision to be able to use the corrective plan that has traceability to undertake calibration. Asking to appearance precision strict gear measures a domain, the lead of NC tooth form of Osaka essence machine is measured machine measure equipment to be able to be opposite the parameter such as the tooth form of gear, teeth directional, pitch undertakes full automatic measure quickly, used the direct and deferent servo that can remove oscillatory effect. The field is created in the car, the power that how enhances gear transmits efficiency to already made crucial technology, because this demand rises gear ceaselessly,measure the precision of machine. Can mix to raise the acceleration of the car comfortable sex, the noise that eliminates engine and transmission case and vibration are very important, especially gear-box, to gear detect precision demand is very high. About the measurement technique of gear, osaka essence machine thinks " still do not have national attestation at present in Japan. Because this must be used,for calibrating fiducial standard gear affirms measure precision, the concerned attestation orgnaization of recommit abroad has a test. " the demand that gauges to high accuracy, high resolution measures parts of an apparatus as positional precision, line coder (Linear Encoder) communal trace to the source the system is inside Japan have not establish. 2004, heidenhain company introduced length precision to detect in factory of name ancient house device. This is German physics labour learns an institute (PTB) the precision calibrating device that takes the lead in developing. With respect to length gauge quantity character, PTB in order to have but the laser of date from sex, standard rule, line coder is a foundation, with aggregate the ground assures the length standard grading of 10 above measure precision. Measure essential factor to waiting besides the temperature beyond length, baric, angle, also establish be calibrating of periodic executive precision to several years with half an year respectively but system of date from sex. In recent years, with coder of graduation staff guage together, absolutely (Absolute) coder already gradually predominate. The coder of Heidenhain company already implemented high accuracy, high resolution (can amount to 10nm) change with high speed communication. The number that is used at measuring dimension precision measures gauge (Digital Gauges) the requirement is had high accuracy, high resolution and to all sorts of work environments get used to ability. The number of company of Sony Manufacturing Systems measures plan product lineup in increased volume newly smaller, precision taller, resolution is smaller (the smallest can amount to 0.

1 μ M) new-style date, the high accuracy that can realize maximum Cheng 12mm is measured. In addition, to satisfy an user flexible the demand that much dot is measured and much interface outputs, this company still was rolled out can agile and corresponding different jumper is counted (can amount to 64 lines at most) the MG set that much interface exports measures module. This company can obtain metric code to maintain to build, can satisfy user requirement, have but the quality of system of calibrating of length of date from sex assures a system, already passed the attestation of standard of ISO 9001 international. Devote oneself to to offer measure integral solution with 3 coordinate machine when undertaking metrical, to ensure of dimension precision but date from sex applies his at work measure examine, need evaluates metrical inaccuracy to be spent surely. For this, need evaluates all sorts of error elements, give inaccuracy in order to calculate to be spent surely. In WGl0 of ／ of ISO ／ TC213 (coordinate is measured machine) in standardizing the job, already set coordinate measures the precision of machine to evaluate a standard, and discussing what inaccuracy spends surely evaluate a standard. In shorten further 3 coordinate measure the measurement of machine time, raise respect of its motion career to existing to compete all the time. Current, raising the technical bottleneck that measures machine shift and the rate that increase decelerate quickly further is oscillatory, wait through using means of the new technology that measure a head, drive and tall tigidity to design, can eliminate vibration effectively, make rise further measure accident to move speed to become a possibility. Measure when 3 coordinate especially machine use at online when detecting, the requirement is machining a line to go up to undertake compensating correction to the temperature error of workpiece. Accordingly, measure equipment to produce business to devoting oneself to to offer the overall program that the issue measures in solving treatment for the user. Measure to 3 coordinate machine, can have not called at present " standard plan " precision measures an instrument. It is OK to use gauge block test and verify one axis and the precision of 2 axes, but the 3 axes precision that should measure machine character to serving as 3 coordinate undertakes test and verify still has defective. Shallow billabong ability grinds 3 coordinate measure the park of Quality Master of compasses of three-dimensional precision test and verify of development the measurement of machine on workbench, in position of positive and negative each are measured 3 times, can be evaluated according to measuring data instant and simple and easy and corrective 3 coordinate measure the geometrical precision of machine. CNC image measures the development of machine to regard as detect stamping workpiece, cast small-sized, thin model the high accuracy that machines a spare parts measures an instrument, guide in sensor the CNC image of use CCD camera is measured machine had rapid development. Current, the freeboard precision image that resolution is less than L μ M measures camera of CCD of machine, equipment and resolution to amount to 0.

The laser altitude meter of 0l μ M, mixture that is used at aggrandizement to measure height measure machine also had developed. Technical respect is measured in nicety, important is right more high accuracy and the workpiece with complex form undertakes efficient measure. Metrical inaccuracy is spent surely is to be used at evaluating to detect not only result, more important is to be used at from consider to detect on the whole cost, in order to build efficient testing system. Want to provide the standard that is a foundation with high accuracy not only, and study even can the technology that accurately imitate assesses complex uncertainty of measurement makes be used actually change, this will be henceforth the main task that nicety measures a domain. The interference that needs affirmatory cutting tool, clamping apparatus in CNC Machining. Although the treatment software such as CAM also can be chosen,deserve to emulate function of imitate desired result, but the accident in treatment or breakdown are an operation normally carelessly when cause, because this still had better use other system issue,advanced travel checks test and verify. Device used the 0SP series CNC that rivers bend greatly to prevent strike a system, no matter be,the hand moves an operation, the interference that CNC device can check workpiece, cutting tool, clamping apparatus automatically to wait, in happen before colliding stop automatically machine. Besides the production with breed and changeful batch, undertake trying machining waiting transforming the manufacturing site of the program in a lot of need, the value of the tool that prevent a fault is increasing increasingly. Cannot not mention CAM software when talking about 5 axes to machine. Through pressing operation guideline set all sorts of treatment conditions reflect operation personnel style reflect CAM. But, like 5 axes treatment jumps over sophisticated treatment in that way, the pretreatment before its are machined spends time more. The automation of CAM can be achieved after all why to plant degree, it is a very big task to the manufacturing industry henceforth. The place on put together is narrated, can use " high additional value is machined " this one keyword will generalize " compound treatment / 5 axes are machined " product development trend and manufacturing site requirement, and the progress of these technologies accumulate the possibility that containing future of change Japan manufacturing industry.
