Below Utopian condition, exploration technology of optics or other blame contact is to measure complex, the optimal method of small mechanical part, but it is highbrow actually. Optical system has the advantage of speed, and avoid make the spare parts is out of shape, but the restriction that also has its oneself, can inspect an edge to cannot reflect the condition at the back of its because of what add workpiece, and optical system cannot fix a few three-dimensional defect for example form of parallel, perpendicular, column or plane. In surveying a system through counting a sensor technology integratedly to go to however, OK all crucial features a complex part are installed in finish in clip. These much sensor measure a system to include to be not osculatory sensor normally -- video, white light and / or laser -- the measurement that uses the surface and side, and touch hairdo and scanning type to measure a head to use the feature that explores those blame to contact plant institute to cannot be achieved to measure, sink for example aperture. Measure a head to be met in unused moment with what the machine tool makes syncretic system retractile. The measurement that explores small feature tradition technology, for example coordinate is measured machine touch hairdo to measure a work up change with getting used to demand. Today, have different the sensor that touchs hair voltage, of different length hit a needle, of different measurement and material measure a needle. But what had changed as a result of the feature is more tiny, these detector can be achieved much smaller still can stabilize sparking have physical restriction. For example, a petty meeting before touching a needle to spark in detector bends, communicated exterior position wrongly. Or a long meeting that hit a needle folds a turn (the edge that came up against Kong Huo chamfer) and recorded a data to nod, and hit a needle actually and did not come up against treat measured surface. The use of the development of production technology and EDM makes machine tiny feature to become a possibility, and spare parts test is very difficult however, for example small hole. In a few application, spark the dimension of bougie or the length that hit a needle can be prevented completely spark measure. Spark the measurement that measures the situation that does not suit application to include little gap, aperture, groove, or rake of Kong Ba model, because groovy detector can be measured,slant the position. There are two kinds of commonly used detectors when treatment. The first kind is to be in already treatment facilities goes up add component, additionally one kind of detector that be called. Latter is loaded when assembling equipment, call compositive bougie. These bougie can tuck up when treatment won't affect treatment, because this does not need,change tool. Compositive detector is used reliable, can use at any time, wait for a problem without interface of cable of such as wire, radio and safe power supply. It is OK that common device installed compositive detector to become judge an environment and make response to the environment. The facility that has these capacity is in encounter the case with smaller and smaller part and spare parts bigger change to fall to show its unique value. As advanced as the communication of controller exploration technology is integrated the software that runs in controller and machine tool. For example Datron Dynamics, milford, n.

Com) , manufacturer of machine tool of milling of CNC of a high speed has ground gave out the 3rd acting compositive exploration system, its the first pace detects place whether correctly, scan next and identify a part, choose correct procedure to undertake machining. The explanation of president Dr. Walter Schnecker of Datron says: "Put wrong part into the machine when operator even, this equipment still can produce a correct part, because explore scanning,be the correct procedure that this spare parts chooses. Small workshop has a lot of spare partses to change the job, they can discover can detect automatically the accuracy that holds clip can reduce changeover and working cycle. " the Z on Datron machine to revise the irregular figure that explores OK identifying to add workpiece face, no matter be accidental,those who appear still is design place is peculiar, detector can help a machine have dynamic compensation to it. Through be opposite raw the scanning of a surface transmits these data to controller to accomplish this. Controller is rough whole face or work place self-correcting. Pass this course, the time that hold clip decreases and product fraction defective is decreased for the smallest. Z to correction detector it is permanent installation is on main shaft edge, just extend when need only come. Be based on such design not to need to change tool, without the obstacle of wire cable, and be in main shaft won't be damaged by the accident when sudden move. Should install three-dimensional exploration device, z can locate to the spare parts to compensation detector and in coordinate of X, Y, Z aspirant travel surface is irregular detect, find the center of aperture and protruding stage, undertake forecasting a quantity to change in order to compensate material before treatment, feedback data controls what a lot of parts can have in information catenary to try a project instead to ISO9000 quality. Installation has Leinishao (Renishaw) the Datron machine of TP20 detector can use pair of complex parts and spare parts feature to undertake metrical, undertake marking in circular surface for example (Logo) sculpture. Normally, three-dimensional process designing needs to adjust the surface to cut profound change in order to ensure the sculpture deepness of level off. Use TP20 surface can be scanned and of spare parts surface irregular can apply in processing data with change, and need not three-dimensional process designing. TP20 has 6 freedom to spend, of motion, touch hairdo to explore a system to improve working cycle. Slight contact comes from Carl Zeiss IMT Corp.

F25 machine (Www.

Com) it is system of a contact, integrated an optical system, include 3 sensor - two are used measure, one uses hand operator. One is mood of the film that suppress report sensor of complete scanning contact can have contact. It also can use as full automatic scanning mode. The new director Gerrit DeGlee of the accurate product of Zeiss points out, the diameter that measure a head is OK small to 0.

12mm, osculatory pressure measures engine model than traditional coordinate experience value is about 100 times less. "This is very important, because allow smaller clip,hold power. Because miniature spare parts is placed to hold may be out of shape, must reckon clip holds power accurately and do not make the spare parts is out of shape " , deGlee says. The optical system that installs on F25 machine, vicinity contacts sensor, can be used independently or use with osculatory sensor union. This system has annular illuminant to be able to undertake process designing according to brightness and direction, with the smallest change the shadow that does not need. The Datron machine that installation has Renishaw TP 20 is OK ensure on circular spare parts cut identically deep. Should want to measure very small or when needing the feature that microscope ability sees, operator sees very hard measure a process. For example on F25 0.

Of 12mm measure a head not to magnify cannot see almost. Because this machine has an optical system to be able to magnify of contact detector measure extent, facilitate image enlarge handlers develops a program to monitor. Optical testing system will be measured directly show go up in test software screen. F25 is not the model that factory workshop uses, , because its high accuracy and lack are right,heat up the control of the influence, especially the environment of the workshop. Fluky measure precision to be less than 250 accept rice (be less than 0.

00025mm or 0.

0000098 inches) . Should measure when achieving such precision, hot effect is very apparent. This type uses stable heat to expand systematic glass-ceramics, this is telescopic development originally. This kind of material eliminated the inaccuracy of hot coefficient of expansion to decide, and need no longer check the hot sensor of this coefficient. The small contact that blame contact explores Smartscope much sensor to check a system to make do not have the deflection that measure a head explores a technology to become a possibility, this product comes from Luo Che of city of American new York this special Optical Gaging Products Inc.

Com) . This technology is called " feather is explored " , of use miniature measure a head and make its do persistent jiggle. This detector is in a very narrow bottom that measure a head has 0.

The bougie of 125 Mm. When bougie is close to the object that be measured, when be close to the jiggle that causes to the surface to change, record measured value. Detector impartiality moves, test system uses the power that is less than １ milligram. OGP says " feather is explored " make little gap, aperture, of groove or aperture it is easy to unplug modular rake measures quantitative change to get, still can explore softness or alterable form material. This technology can be used at X, y and Z axis. To prevent damage, bougie shrinks in unused moment return protection in the space, just extend when need is measured automatically only come. Another comes from the blame contact of OGP to measure sensor to have high side position and high resolution when measuring the surface, this sensor is sensor of Rainbow exploration Baiguang, it can get inferior resolution of miniature Z axis. This technology uses the off color of patulous axis in a lens, the wavelengh of every light is in the dot that its differ on smooth axis. Color analysis makes Rainbow detector not sensitive to exterior reflex and coarse change. Should use in much sensor system, detector can offer blame contact to measure with scanning surface, exterior detail can be any appearances and the scanning on the side makes this area figure. Much sensor system is integrated and all complex part has geometry, the appearance of prism appearance and free configuration, the opening that has critical space or fixed position are nodded and a lot of positions on the spare parts have fundamental connection, the measurement that needs many sensor system. Much sensor measures equipment to be able to use specific sensor to measure measure specific feature, regard a spare parts as the one part that entire character depicts. The system is surveyed in much sensor in, software conformity is all sensor is a serious consideration. Optimal software conformity includes consideration all sensor that using, because this measures method to go up in,in any dots these sensor can be used, and integrated not of beautiful before needing to be used every time calibration. And, efficient software allows to handle and analyse the data that comes from any sensor, way is measured in in can handle video border very easily to nod, laser nods aggregate group and scanning contact to explore data. "High capacity (great distance) much sensor is small of the excel nicety of exploration system small survey a system, a crucial good point is to be able to be in same a data file is medium, the dimension of the measurement of small feature and small feature connection rises, and can be on whole spare parts have fixed position. " the president Fred Mason of Optical Gaging Products points out. The great distance that contains tiny detector measures a system to be able to be in a file small to the key of the spare parts feature and correlation of a data of macroscopical dimension and its position. The small feature that can go up to the spare parts undertakes the tiny detector that contains traditional video to measure system and high resolution exact location, or as associated as crucial data. Small sensor can survey a system with the much sensor at any capacities in. The fixed position that important video measures a system to should consider to ensure equipment has high resolution and the tall enlarge to position of specific spare parts are diploid. The measurement in should exploring a system systematic performance is superior when having high accuracy, small exploring is the most accurate. Measure in integrated video is mixed in the course small explore measure, can make the feature with complete spare parts and need not the user intervenes. CNC Milling CNC Machining
