Industry is become with fault of computer X ray picture (CT) scanning is a kind burgeoning detect technology, it detects to reduce product trial-produce considerably cost, and in three-dimensional nondestructive blemish offerred the well and truly analytic workpiece interior in detecting likelihood. Traditional nondestructive detects the technology can be used at detecting only spare parts and the exterior geometry appearance that assemble a product. If need to detect the component with a very complex structure, detect traditionally methodological need holds work with clamping apparatus clip, in order to found specific measurement datum plane, measure with coordinate of machine touch hairdo to measure a head to be finished in time whole detect process, or the outside range that use vision measures systematic mapping workpiece. The interior of a few workpiece previously checks a method to need to use scanning of ray of 2 dimension X, or use detect ruinously means. The basic form that industrial CT scans and medical CAT scanning are similar, just technology of this kind of CT is being used at scanning now all sorts of industry component, is not human body. Medical CAT scanning basically is used at visible purpose, and industrial CT scanning should come true not only visible, and undertake metrical even. Industrial CT scanning is interweave image of ray of 2 dimension X form workpiece interior and exterior and three-dimensional video process. Because use X ray scanning, because this can be in,need not place held free position to fall to undertake detecting to flimsy and fragile component. Because need not bring to bear on to workpiece,measure force and undertake placing holding, its nature place is in when because this can ensure,workpiece is detected. After scanning is finished, undertake reframing to data, undertake data processing with CT CAD software next, dimension of implementation spare parts and CAD model contrast, geometry and public errand (GD ＆ T) analysis, spare parts and spare parts contrast, component / thick analysis of blemish analysis, hole analysis and wall, generate the CAD data that converse project place needs. Use software of this kind of CAD, the user of firm introduction also gets fault scanning data easily, and open / shut in-house component density scanning, by density the value undertakes colour coding and measure wait for a function. The type that industrial CT scans is current, the system of scanning of CT of industry of city carry out that is based on X ray has two kinds of basic kinds: Sector bundle model with line form bundle model. Sector bundle when CT scanning system works, the workpiece on park circumgyrate workbench circles his vertical axis rotates, be in at the same time perpendicular and sectional scanning of fault of ray of aspirant travel X. This kind of system has very expensive work to analyse precision, but to be being measured the dimension of workpiece and density have certain restriction (dimension is less than 12 cubic metre inch, density is less than 8g/cc) . The precision of system of industrial CT scanning and scanning resolution shoot line means length and workpiece density according to X and each are not identical. Generally speaking, sector bundle the resolution limits of CT scanning system is 10 - 300 μ M, precision limits is 3 - 25 μ M. The price of this kind of system differs to 1.2 million dollar from 250 thousand dollar, the reason of price six to one is his scanning resolution, can measure workpiece the largest size and value of scanning of the biggest density are different. Sector bundle the average sweep time of CT scanning system is about 1 - 3 hours, the aftertreatment time that analyses place of data of every workpiece CT to need is 1 hour about. Line form bundle when CT scanning system works, undertake to the workpiece that rotates on circumgyrate workbench the fault with sectional level scans, next with a few kinds beforehand the perpendicular increment of buy repeats process of this one scanning. Think commonly, the precision level of this kind of system under sector bundle scanning system, basically apply to detect size is larger and / or the spare parts with higher density and component (dimension is less than 39 cubic metre inch, density is less than 16g/cc) . Line form bundle the resolution limits of CT scanning system is 150 - 1000 μ M, measure precision each are not identical. Normally, the price of this kind of system differs to 5 million dollar from 500 thousand dollar. Line form bundle the sweep time of CT scanning system is 3 - differ 24 hours, basically suffer the effect of a requirement scanning resolution. Because equipment weight and place want the restriction of X ray licence, technology of industrial CT scanning does not have portable sex. The application that industrial CT scans (1) hole analysis uses Yu Zaihou the wall is plastic, note model or the size that in-house hole determines in combining the nondestructive of material to detect and position. The in-house fiber orientaton that function of this kind of analysis also can use at identifying mid fiber of material of colophony of Bo fine fill and short staple. (2) mural thick analysis basically is used at blowing model model and the industry that pack, detect in the nondestructive of complex part in, measure the little change with profound wall well and truly. (3) generate CAD data to be after scanning, through synthesizing image of ray of 2 dimension X three-dimensional model, can obtain the workpiece interior that can be used at converse project and exterior CAD data easily. Through providing the data of feature of interior of the workpiece that print and appearance of exterior surface geometry, this function also can be used at 3D Printing form cutting. (4) package / the in-house component that blemish analysis is used at analysing clench the teeth or buckles closely together. Through pressing density the value undertakes colour coding, can detect easily the component that is concealed in package before, discovery cooperates blemish and action place. (5) spare parts and analysis of spare parts contrast are used at will two are put together by scanning spare parts undertake contrast, the spare parts that if be opposite,machines with two kinds of different technology, part that produces before and new-style spare parts, or what produce on facilities of two different treatment is same kind the spare parts undertakes contrast. Pass this kind of contrast, can distinguish a difference between the spare parts easily, shorten thereby the processing time that cost does not poor, or use at test and verify some kind of craft. (6) spare parts and analysis of CAD model contrast are used at the spare parts that will be scanned and its CAD to design data to undertake comparing is opposite. Compare through this kind right, can get much ground more quickly than traditional method to undertake first analysis to the product in trial-produce of this locality or abroad. Normally, when undertaking first trial-produce, detector is provided have not make come out, should be commonly after first trial-produce the coordinate that work out of ability of a month gives a part is measured machine (CMM) detect program. Industrial CT scanning can finish the fast contrast of spare parts and its CAD model to analyse inside a few days after first trial-produce. Master spare parts and CAD contrast to analyse a result through be after first trial-produce, with respect to the cost that can reduce modification mould, experimental treatment and follow-up trial-produce greatly. (7) geometrical dimension and public errand (GD ＆ T) the analysis is used at contrasting with spare parts and CAD model functional photograph is united in wedlock, be opposite at the same time the geometrical dimension of a lot of predefine and public errand (GD ＆ T) several foothold undertake an analysis, in order to satisfy process of approval of manufacturing spare parts (PPAP) requirement. In the course that produces to batch from first trial-produce, function of this kind of analysis is very useful, have very tall cost effectiveness, can reduce considerably much model of antrum spare parts detect cost. Once was CT data set to establish program of first GD ＆ T, can be opposite dots of all data of GD ＆ T have fast transition, apply its at subsequently spare parts scanning. Besides plastic industry, various supplier and main car manufacturer, die manufacturer also can scan from industrial CT afore-mentioned analysises of the technology are benefited in the function.
