三坐標(biāo)測量技術(shù)小結(jié)

三坐標(biāo)

三坐標(biāo)測量機(jī)，它是指在一個(gè)六面體的空間范圍內(nèi)，能夠表現(xiàn)幾何形狀、長度及圓周分度等測量能力的儀器，又稱為三坐標(biāo)測量儀或三坐標(biāo)量床。三坐標(biāo)測量機(jī)的工作原理:

任何形狀都是由空間點(diǎn)組成的,所有的幾何量測量都可以歸結(jié)為空間點(diǎn)的測量,因此精確進(jìn)行空間點(diǎn)坐標(biāo)的采集,是評(píng)定任何幾何形狀的基礎(chǔ)。

坐標(biāo)測量機(jī)的基本原理是將被測零件放入它允許的測量空間，精確的測出被測零件表面的點(diǎn)在空間三個(gè)坐標(biāo)位置的數(shù)值，將這些點(diǎn)的坐標(biāo)數(shù)值經(jīng)過計(jì)算機(jī)數(shù)據(jù)處理，擬合形成測量元素，如圓、球、圓柱、圓錐、曲面等，經(jīng)過數(shù)學(xué)計(jì)算的方法得出其形狀、位置公差及其他幾何量數(shù)據(jù)。

在測量技術(shù)上，光柵尺及以后的容柵、磁柵、激光干涉儀的出現(xiàn)，革命性的把尺寸信息數(shù)字化，不但可以進(jìn)行數(shù)字顯示，而且為幾何量測量的計(jì)算機(jī)處理，進(jìn)而用于控制打下基礎(chǔ)。

三坐標(biāo)測量儀可定義為—一種具有可作三個(gè)方向移動(dòng)的探測器，可在三個(gè)相互垂直的導(dǎo)軌上移動(dòng)，此探測器以接觸或非接觸等方式傳送訊號(hào)，三個(gè)軸的位移測量系統(tǒng)(如光學(xué)尺)經(jīng)數(shù)據(jù)處理器或計(jì)算機(jī)等計(jì)算出工件的各點(diǎn)坐標(biāo)(X、Y、Z)及各項(xiàng)功能測量的儀器‖。三坐標(biāo)測量儀的測量功能應(yīng)包括尺寸精度、定位精度、幾何精度及輪廓精度等。應(yīng)用領(lǐng)域：

形狀和位置公差與檢測

零件幾何要素和形位公差的特征項(xiàng)目一、零件幾何要素及其分類

形位公差的研究對象幾何要素（簡稱要素）

（一）要素：構(gòu)成零件幾何特征的點(diǎn)、線、面。見書圖3-1（二）要素的分類1、按存在的狀態(tài)分

理想要素：具有幾何學(xué)意義的要素，即幾何的點(diǎn)、線、面，它們不存在任何誤差。圖樣上表示的要素均為理想要素。

實(shí)際要素：零件上實(shí)際存在的要素。標(biāo)準(zhǔn)規(guī)定：測量時(shí)用測得要素代替實(shí)際要素

2、按結(jié)構(gòu)特征分

輪廓要素：構(gòu)成零件外廓、直接為人們所感覺到的點(diǎn)、線、面各要素。如圖3-1中1、2、3、4、5、6都是輪廓要素。

中心要素：具有對稱關(guān)系的輪廓要素的對稱中心點(diǎn)、線、面。如圖3-1中7、8均為中心要素。

3、按檢測時(shí)的地位分

被測要素：圖樣上給出了形位公差要求的要素。是被檢測的對象。

右圖中，φd2的圓柱面和φd2的臺(tái)肩面都給出了形位公差，因此都屬于被測要素�；鶞�(zhǔn)要素：零件上用來確定被測要素的方向或位置的要素，基準(zhǔn)要素在圖樣上都標(biāo)有基準(zhǔn)符號(hào)或基準(zhǔn)代號(hào)，如右圖中φd2的中心線即為基準(zhǔn)要素A。

4、按功能關(guān)系分

單一要素：僅對被測要素本身給出形狀公差的要素。如上圖中φd2的圓柱面是被測要素，且給出了圓柱度公差要求，故為單一要素。

關(guān)聯(lián)要素：與零件基準(zhǔn)要素有功能要求的要素。（即相對于基準(zhǔn)要素有功能要求而給出位置公差的要素）。如上圖中，φd2的臺(tái)肩面相對于φd2圓柱基準(zhǔn)軸線有垂直的功能要求，且都給出了位置公差，所以φd2的圓柱臺(tái)肩面就是被測關(guān)聯(lián)要素。

三坐標(biāo)怎樣用來進(jìn)行曲面檢測？模的情況下用三坐標(biāo)測量機(jī)對曲面件檢測，通常是，先在CAD軟件里用相關(guān)命令在曲面數(shù)模上生成截制測量機(jī)到對應(yīng)的位置，進(jìn)行檢測，并比較坐標(biāo)值的偏離。這種方法需要設(shè)計(jì)人員額外提供理論數(shù)據(jù)現(xiàn)，對于單點(diǎn)測量來說，由于無法確定矢量方向，測頭的補(bǔ)償根本無法實(shí)現(xiàn)。因此，這種辦法具有一量

進(jìn)行檢測是CMM測量技術(shù)發(fā)展的需要。由于曲面建構(gòu)技術(shù)比較復(fù)雜，在CAD應(yīng)用范疇里也屬于高端完成。在測量軟件內(nèi)，則是通過導(dǎo)入設(shè)計(jì)數(shù)模而利用的問題。為了實(shí)現(xiàn)這一目的，就必須解決好四個(gè)方測尖補(bǔ)償、理論值捕獲。

首先要做的工作，當(dāng)然是保證數(shù)模正確導(dǎo)入到測量軟件。事實(shí)上，由于技術(shù)、利益等眾所周知的原因同的軟件和格式，例如國內(nèi)影響比較大的UG、PROE、CATIA等，均不能直接互讀文件。國際上建立了一系列的數(shù)據(jù)交換標(biāo)準(zhǔn)，如國際標(biāo)準(zhǔn)數(shù)據(jù)交換STEP(StandardfortheExchangeofPro標(biāo)準(zhǔn)IGES(InitialGraphicsExchangeSpecification)等。盡管IGES標(biāo)準(zhǔn)存在數(shù)據(jù)文件大、轉(zhuǎn)換時(shí)間是目前應(yīng)用最廣泛的接口標(biāo)準(zhǔn)，絕大部分CAD軟件均支持該標(biāo)準(zhǔn)，我國也將IGES作為推薦標(biāo)準(zhǔn)。能的測量機(jī)軟件，均支持IGES格式。差異基本上主要體現(xiàn)在復(fù)雜數(shù)模輸入后個(gè)別曲面的丟失、破損0M的數(shù)模，有的可能用幾十秒鐘，有的可能要幾分鐘。目前市面上比較有名的CMM測量軟件，均基測量儀自主研發(fā)的ZCRMDT測量軟件，導(dǎo)入數(shù)模到檢測軟件的情況，數(shù)模大小46M多。

軟件，一些測量機(jī)軟件商也開發(fā)了各種直讀接口，如UG文件直讀、PROE文件直讀等，不需中間文過，這種接口一般都需要另外購買。

坐標(biāo)測量機(jī)軟件的一項(xiàng)重要內(nèi)容，無論有無數(shù)模，都必須通過對齊，將機(jī)器坐標(biāo)系與工件坐標(biāo)系保持一比性。

于箱體類零件，基本都采用3-2-1方式建坐標(biāo)，利用面、線、點(diǎn)特征來確定坐標(biāo)軸和原點(diǎn)，通過建立工件坐標(biāo)系來將工件找正，這也是最

、最準(zhǔn)確的對齊方法。應(yīng)盡量選用加工好、范圍大的特征來作為建坐標(biāo)基準(zhǔn)，以減小對齊產(chǎn)生的誤差。通常，對于建立的坐標(biāo)系，還需要可

進(jìn)行平移、旋轉(zhuǎn)等操作，以產(chǎn)生新的對齊。

于不規(guī)則形體，計(jì)算就要復(fù)雜得多。如果工件上有明確的特征點(diǎn)，如3個(gè)孔心，則通常測量出實(shí)際值，與理論值對應(yīng)，進(jìn)行3點(diǎn)找正。

們經(jīng)常會(huì)遇到工件上沒有明確特征的情況，即我們無法準(zhǔn)確的將測量值和理論值直接對應(yīng)。對于該情況，測量軟件常用的是迭代找正的方法

于單點(diǎn)觸發(fā)采數(shù)的測量機(jī)，通常是軟件在數(shù)模曲面上選取多點(diǎn)作為目標(biāo)點(diǎn)，所選取的點(diǎn)應(yīng)能在全部6個(gè)自由度上固定零件，以防零件出

轉(zhuǎn)和移動(dòng)，然后將測量機(jī)移動(dòng)到工件上盡量對應(yīng)的位置采集實(shí)測點(diǎn)，軟件將測量點(diǎn)在數(shù)模上目標(biāo)點(diǎn)的附近區(qū)域進(jìn)行迭代找正，直到找正誤差

指定的精度內(nèi)。有的測量軟件在迭代超差時(shí)，將指導(dǎo)你重新測量到更接近的點(diǎn)進(jìn)行更準(zhǔn)確的計(jì)算。

有種情況是直接測量多個(gè)點(diǎn)，軟件將該點(diǎn)群與理論數(shù)模進(jìn)行最佳匹配計(jì)算，將點(diǎn)群與數(shù)模一步步對齊，直到點(diǎn)群與數(shù)模的偏差均方根最小

方法點(diǎn)數(shù)越多越準(zhǔn)，但同時(shí)計(jì)算越復(fù)雜，對計(jì)算機(jī)要求較高，通常在掃描點(diǎn)云的對齊中，用得比較多。

管每種軟件關(guān)于對齊都有不同的分類和特點(diǎn)，但基本主要采用以上方法。

、測尖補(bǔ)償

前，三坐標(biāo)測量機(jī)用得最多的是機(jī)械觸發(fā)式測頭，配以紅寶石測針，必然會(huì)帶來測尖補(bǔ)償?shù)膯栴}。

于平面、圓等標(biāo)準(zhǔn)特征，可以通過整體偏置的方式自動(dòng)補(bǔ)償測頭，對于連續(xù)掃描的曲線，也可以用同樣的方式自動(dòng)處理。但對于曲面測量時(shí)

常遇到的單點(diǎn)測量，如何解決測尖補(bǔ)償問題呢？

單獨(dú)對一點(diǎn)進(jìn)行補(bǔ)償，則必須知道補(bǔ)償?shù)姆较蚴噶�，也即是接觸點(diǎn)處的法向矢量方向。為了找到該法線方向，比較準(zhǔn)確的做法是，在測點(diǎn)的

邊測量個(gè)微平面，以該微平面的法向視為測點(diǎn)處曲面的法向，從而完成測尖補(bǔ)償。

于工件測點(diǎn)附本身曲率變化不大的地方，或者工件與數(shù)模本身偏差較小的情況下，如果要求不高，為了減少采點(diǎn)數(shù)，也可以不測量微平面

件直接以測點(diǎn)刺穿數(shù)模的方向矢量進(jìn)行測尖補(bǔ)償，即以數(shù)模上該處的法向矢量代替工件上實(shí)測處的法向矢量做為測尖補(bǔ)償?shù)姆较�。但是如�?/p>

件與數(shù)模本身該處曲率偏差大，則測尖補(bǔ)償將不準(zhǔn)，導(dǎo)致測量數(shù)據(jù)不可靠。

于非接觸式測頭，不存在測尖補(bǔ)償問題。

、理論值捕獲

解決了數(shù)模的導(dǎo)入和對齊后，理論值的捕獲就比較簡單。對于圓等標(biāo)準(zhǔn)特征，軟件只需要能從CAD數(shù)模上選取識(shí)別該特征，即可直接從

性中提取理論值。對于自動(dòng)測量來說，就可以直接根據(jù)數(shù)模特征進(jìn)行編程，指導(dǎo)機(jī)器運(yùn)行到特征的理論值位置附近進(jìn)行測量。

于曲面工件上的點(diǎn)，通常分為曲面點(diǎn)和邊緣點(diǎn)，有的軟件分得更細(xì)。對于曲面上的點(diǎn)，通過直接測量，測量點(diǎn)沿?cái)?shù)模曲面法向投影到曲面上

可獲得理論點(diǎn)。但邊緣點(diǎn)就不同了，邊緣是CAD曲面的邊界所在，例如，鈑金件的邊，最簡單的如方體的棱邊等。如果要檢測邊緣上的點(diǎn)于測針無法直接準(zhǔn)確測量到，并且測頭的補(bǔ)償方向無法確定，因此，無法直接測量，只能采用間接測量的方式。通常，其處理原理如圖

示，為了測量邊緣上P點(diǎn)，可以在其兩邊測點(diǎn)。此例采用前3點(diǎn)用于確定上面，第4,5點(diǎn)確定邊界方向，而最后一點(diǎn)6確定目標(biāo)點(diǎn)的位置

投射到前面確定的邊所產(chǎn)生的點(diǎn)，視為邊緣測量點(diǎn)，其理論值為數(shù)模中曲面邊緣距其最近點(diǎn)。

過以上方式，即可實(shí)現(xiàn)邊緣點(diǎn)的檢測。具體到不同軟件，可能有不同的處理方法。

．曲面測量軟件現(xiàn)狀

于3D數(shù)模對曲面工件進(jìn)行檢測，在三坐標(biāo)機(jī)測量里屬于高級(jí)應(yīng)用范疇，一般在高端測量軟件才包含該功能。目前國內(nèi)市場上比較常見的如

C-DMIS的CAD++版，VIRTULDMIS等，它們是由WILCOX、ENTELEGENCE等專業(yè)測量機(jī)軟件公司開發(fā)而成。POWERINSPECT由于其在數(shù)模處理上的功能較強(qiáng)，也被引用到坐標(biāo)機(jī)上，它是由英國的CAD/CAM軟件商DELCAM提供，這也體現(xiàn)了測量機(jī)軟件與CA

件結(jié)合越來越緊密的趨勢。

實(shí)上，對于曲面質(zhì)量評(píng)價(jià)，作為曲面建構(gòu)、編輯、分析的一部分，CAD軟件制造商較早就有比較好的解決辦法，尤其是在逆向工程處理軟

，在將采集的點(diǎn)云處理成曲面后，往往需要比較點(diǎn)云和設(shè)計(jì)曲線、曲面的偏離，以便在保證精度的同時(shí)提高表面質(zhì)量。圖4為imagewa
