Metric device expands the applied limits of CMM manufacturing area, and offerred special and metric alternative. In complex in the treatment process with precious product part, workpiece normally from flexible but machine tool of process designing computerized numerical control gets off, use next blame is flexible may a of process designing custom-built gauge undertakes checking. "Hard " metric -- means is appointed the spare parts is designed and build, the work that approachs a machine through producing the measurement unit of area to be opposite offers a kind of way that measures quickly. However hard metric also may be costly. Say according to place of Beau Easton of product quality manager, the manufacturer of jet-propelled motor component that to be in Ohio Xin Xin mentions then, design, build and safeguard hard gauge to may want to cost 20000 dollars. If the design of the spare parts produced a change, can cause gauge to also need a change, so the expense that this may want to raise thousands of dollar more. Graph a of 1 hard gauge but process designing choice, measure a part through checking original to be a standard with a CMM namely, so that use " equatorial " the system will bring CMM precision for the workshop. What this photograph shows is medium measurement is used in Meyer Tool system the Renishaw of expert of weights and measures technique of headquarters of United States of city Hoffman Estates introduced Yilinuosi recently a new metric system, aim cut with these metric and relevant charge. Of this company " equatorial " the system is around the move is sudden a when compare spare parts of a new treatment and original of a reliable measure but measurement unit of motion of process designing parallel and of the design. Meyer Tool is one of the earliest users that handle workshop examination. Through working in a new development unit a person operating from within in coordination with outside forces is used " equatorial " system, manufacturer can avoid to need at least 4 hard gauge and the cost that bear. Equatorial measurement unit is similar to a small-sized coordinate to measure machine, because it contacts bougie through using, will measure the spare parts feature that gives 3 measure. This device takes on to measure the role with different aircraft with coordinate not only in measuring a process, and still depend on coordinate to measure machine -- because coordinate is measured opportunity is potential it is equator is measured but the fountainhead of date from sex. Not be to resemble coordinate measuring place is affirmatory like machine accuracy, but acceptance of equatorial measurement unit can repeat. In measuring a process difference appears particularly important, the gage because of equatorial to containing system, most crucial is from measure accurately advocate the component begins. Graph the feature of 2 this device is it be designed to be structure of a parallel campaign, allow to be measured quickly with dimension but repeatability is measured use to survey a system accurately (for instance a coordinate in temperature control room is measured machine) , advocate dimension is decided, can be far from the influence that temperature change and other workshop effect bring. However, as long as advocate component and manufacturing spare parts are likeness for dimension and feature, and be make by same material. Can believe firmly, this OK and appropriative actual part and environment concern a of change reliable guidance. For example, if because because weather is torrid,workpiece is producing section,be and happened to expand, so, original can appear as much identical proportional expand. Need is done through measuring original " zero balance " , accordingly, the heat of purify workpiece expands to just affect a spare parts to measure a factor of precision. "Zero balance " the pattern of zero of as hard as gauge is similar. Measure original regularly any drift data of the accuracy in corrective process. Pass pair of original every other 3 hours remeasure measure, meyer Tool is used " equatorial " the system enhanced the definition in metric process. As a result of partial plant but the design characteristic of parallel motion, accordingly, to original or manufacturing spare parts periodic measure meet a few faster. To Meyer Tool character, measure cycle to need 2~6min, the speed of this process depends on the complexity of spare parts structure. Use probe of scanning of a successional contact (at present Meyer still does not have such doing, in planning nevertheless) the likelihood makes " equatorial " the system is measured in cycle inside capture conveniently the feature of thousands of several foothold. Graph 3 use contain " equatorial " bougie of scanning of a of the system successional contact, make pass capture quickly thousand several foothold will decide a feature becomes a possibility Bridget Nolan of manager of Meyer Tool SPC says, "We are using equatorial system, make diameter of GD&T exact position, nick, aperture, outline and wave motion measure. " the probe that at least 4 use to differ in the program that runs in the workshop. Commutation wearing allows device to change automatically bougie. The software application cent of this system is two level. The engineer uses but the software of process designing version will establish inspection program. Aborning, a clipper-built version makes operator chooses correct procedure easily to undertake checking. The change that produces between spare parts number can ask to change in " equatorial " the change of the clamping apparatus on systematic unit. Meyer Tool became all sorts of examination settings on different clamping apparatus. Can make corresponding choice to substituting clamping apparatus, this is in previously, be aimed at different spare parts, this workshop may need all sorts of separate hard gauge. And now, need to pass very short time to change with respect to what can realize different gauge only, in addition, return the part that can use identical gauge to measure a feature to differ completely, and can be opposite corresponding advocate spare parts gauge makes apace zero balance.
