As the development of technology, taller and taller also to the treatment quality requirement of the product. How does ability make the product that gives high grade qualification, this is the chief difficult problem that is placed before compatriots, 3 coordinate measured the development of machine to be offerred for this can realize join with advanced numerical control machine tool namely, can come true to undertake with the design digital-to-analogue is delivered again. Realized design, treatment thereby, examine be an organic whole without seam a link to detect control circulatory system. Because this is hit to offer high grade product,laid a foundation. Design, treatment, detect unifinication circulatory system introduces: It is currently in domain of industry of cool one's heels of car, boat, the CAD design software of the mainstream satisfies the requirement that complex external form designs very hard still, the manual model that still needs to be made according to waiting by greasy filth, clay, wood or fiber glass will come true, but need of this kind of model is machined with numerical control machine tool, with respect to need model of word of know exactly about sth weaves machine program, and measure with 3 coordinate machine measure into line scanning, attainable this number model. Above all, will manual model is placed clamp of the fixed position in machine is measured in 3 coordinate, undertake metrical the data set nodding the cloud with forming a model next, the current form that adopts a file finally (Igs, step) guide the data set nodding the cloud that forms by these geometrical features in CAD/CAM software (like MasterCAM, pro/E, the) such as UG, use these to nod the cloud to form curve, curved surface hypostatic perhaps. In the hypostatic process that build a model, we must combine the feature of original model to edit the dimensional curve feature that forms by dot cloud, dominate the reasonable niche of turning point. The curve can be join of precise point point, OK also plan to close form, or interpose at both between. Found a curve according to need, the number that can change reference point will adjust a curve. Reference point grow in quantity criterion appearance be identical has been spent, reference point reduces a curve relatively smooth suitable. The curvature that can pass a curve will judge smooth compliance of the curve, also can check curve and the be identical sex that scanning chooses, what still can change curve and other curve is successional (join, tangent, curvature is successive) . The design that also can have a model at the same time is revised etc. Anyhow, the curve edits and modification process of the hypostatic design that build a model is technical with experience sex very strong level, need has professional technology personnel to finish. It is to use design digital-to-analogue to undertake setting of cutting tool method forms numerical control machine tool to be able to identify code of G, M next, input its numerical control machine tool to process a product. 3 coordinate are used to measure again after treatment is finished machine the product that will measure treatment to come out, reach quite with original design digital-to-analogue machining error, if accord with the requirement of the model, criterion batch production. Conversely, revise treatment craft to perhaps undertake repair is machined again. The 3 coordinate that car hub goes against project example to use Xi'an force heart to measure equipment limited company to produce now instead measure machine measure software function and CAD/CAM software MasterCAM to have car boss converse project undertakes elaborating: Measure equipment: Heart of force of Xi'an of FLY1086 CNC3000 (measures equipment limited company to make) diagnostic analysis: Car hub attributes swing tower part, important surface is outside outline and tire cooperate the surface, the requirement is smooth level off, satisfy the high speed travel of the car, central opening position is spent etc. Survey plan: Divide second installation to measure, coordinate department definition is in central aperture center. It is OK to measure swing tower generatrix to use CAD/CAM software to rotate bus rotate bus form swing tower, next will other measure an element to undertake gyral, drawing perhaps is excised, array feature editor will form hub entity. Use software: 3 coordinate measure machine measure software MasterCAM to measure software specification: The 3 coordinate that Xi'an force heart measures equipment limited company to produce are measured machine measure software to be able to come true fictitious measure, off line process designing, successive scanning is measured, form the function such as output of tolerancepublic errand assess, CAD. Scan continuously especially measure reach CAD to output a function to make converse project becomes a possibility. Master CAM explains: Can realize CAD/CAM function, whether does clew of the meeting when inputting the data that nod the cloud to pursue incorporate his, if incorporate,a certain number of data files that can fasten same coordinate next generating incorporate make a file, cloud of facilitating editor dot and curve, curved surface is hypostatic perhaps wait. Provide gymnastics to make move: Graph sketch map of 1 operation flow shows 1 times like the graph: Put hub model in 3 coordinate to measure first in machine, undertake scanning metrical getting nodding cloud data, pass CAD software to undertake designing modification again. Graph 2 it is the diagnostic curve that guides the data in MasterCAM nods the cloud to form namely. The course rotates, after drawing, excision and array editor design are amended, if the graph is shown 3 times,form hub digital-to-analogue entity to be in MasterCAM. Graph cloud atlas of 2 number foothold pursues it is OK that substance of 3 hubs digital-to-analogue adopts current form next be defeated by design digital-to-analogue to 3 coordinate machine to undertake the operation such as off line process designing forms a spare parts to measure an order. Also can undertake numerical control process designing forms code of G, M directly, machine tool of input numerical control undertakes machining. 3 coordinate measure reoccupy of good treatment finally hub spare parts machine the requirement that whether the part that undertakes proved recipe can know treatment comes out metrical check accords with primitive hub model. If accord with, can batch production. Conversely, be machined into travel repair again or revise treatment craft. Realized design, treatment so, detect of unifinication without crack link circulatory system, and detect mediumly in this system be measure with 3 coordinate machine will come true for the standard, and it is the input that computer has data directly, output, avoided factitious blueprint to deliver the error that brings in the process. Also rose to design the efficiency of research and development at the same time, shortened design, treatment, examining time, make high grade product can faster, better put in the market. The last word is converse the project is a new technology that can promote industry to develop quickly, it is the new measure that rise and improves way of traditional design thinking. We are in only long-term production fumbles ceaselessly in practice, ability makes this technology develops its tremendous energy and efficiency. CNC Milling
