CMM (lub tshuab ntsuas sib koom ua ke) yog ib qho cuab yeej tseem ceeb uas siv rau kev ntsuas qhov tseeb ntawm cov khoom geometric nyuaj hauv ntau yam lag luam xws li tsheb, aerospace, thiab kev kho mob. Txhawm rau kom ntseeg tau tias cov txiaj ntsig ntsuas tau meej thiab sib xws, lub tshuab CMM yuav tsum tau nruab nrog cov khoom granite zoo uas muab kev txhawb nqa ruaj khov thiab nruj rau cov ntsuas ntsuas.
Granite yog ib yam khoom zoo tagnrho rau CMM Cheebtsam vim nws qhov kev ua haujlwm siab, cov coefficient thermal expansion qis, thiab kev ruaj khov zoo heev. Txawm li cas los xij, zoo li lwm yam khoom siv, granite kuj tuaj yeem hnav tawm raws sijhawm vim kev siv tas li, cov yam ntxwv ib puag ncig, thiab lwm yam. Yog li ntawd, nws yog ib qho tseem ceeb los soj ntsuam qib kev hnav ntawm cov khoom granite thiab hloov lawv thaum tsim nyog kom ntseeg tau tias qhov tseeb thiab kev ntseeg tau ntawm CMM kev ntsuas.
Ib qho ntawm cov yam tseem ceeb uas cuam tshuam rau kev hnav ntawm cov khoom granite yog qhov zaus ntawm kev siv. Qhov ntau zaus ntawm cov khoom granite siv, qhov ntau dua nws yuav hnav tawm. Thaum soj ntsuam qhov degree hnav ntawm cov khoom granite hauv CMM, nws yog ib qho tseem ceeb uas yuav tsum xav txog tus naj npawb ntawm kev ntsuas voj voog, zaus ntawm kev siv, lub zog siv thaum lub sijhawm ntsuas, thiab qhov loj ntawm cov ntsuas probes. Yog tias cov granite siv rau lub sijhawm ntev thiab qhia cov cim ntawm kev puas tsuaj, xws li tawg, chips, lossis pom kev hnav, nws yog lub sijhawm los hloov cov khoom.
Lwm yam tseem ceeb uas cuam tshuam rau kev hnav ntawm cov khoom granite yog qhov chaw ib puag ncig. Cov tshuab CMM feem ntau nyob hauv cov chav ntsuas kub kom tswj tau qhov chaw ruaj khov rau kev ntsuas kom raug. Txawm li cas los xij, txawm tias nyob hauv cov chav tswj kub, av noo, plua plav, thiab lwm yam ib puag ncig tseem tuaj yeem cuam tshuam rau kev hnav ntawm cov khoom granite. Granite yooj yim rau kev nqus dej thiab tuaj yeem tsim cov kab nrib pleb lossis chips thaum raug dej noo rau lub sijhawm ntev. Yog li ntawd, nws yog ib qho tseem ceeb kom khaws qhov chaw hauv chav ntsuas kom huv, qhuav, thiab tsis muaj cov khib nyiab uas tuaj yeem ua puas rau cov khoom granite.
Yuav kom paub tseeb tias qhov ntsuas raug, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas cov xwm txheej ntawm cov khoom granite thiab txiav txim siab seb lawv puas xav tau hloov. Piv txwv li, kev tshuaj xyuas ntawm qhov chaw granite kom pom tias nws puas muaj kab nrib pleb, chips lossis qhov chaw hnav pom qhia tias cov khoom xav tau hloov. Muaj ntau txoj hauv kev los ntsuas qib hnav ntawm cov khoom granite hauv CMM. Ib txoj hauv kev yooj yim thiab yooj yim yog siv ntug ncaj los xyuas seb puas tiaj tus thiab hnav. Thaum siv ntug ncaj, them sai sai rau tus lej ntawm cov ntsiab lus uas ntug kov cov granite, thiab xyuas seb puas muaj qhov sib txawv lossis thaj chaw ntxhib raws qhov chaw. Lub micrometer kuj tseem siv tau los ntsuas qhov tuab ntawm cov khoom granite thiab txiav txim siab seb puas muaj qhov twg tau hnav tawm lossis lwj.
Xaus lus, qhov xwm txheej ntawm cov khoom granite hauv lub tshuab CMM yog qhov tseem ceeb rau kev ua kom muaj kev ntsuas tseeb thiab raug. Nws yog ib qho tseem ceeb uas yuav tsum soj ntsuam qhov kev hnav ntawm cov khoom granite tsis tu ncua thiab hloov lawv thaum tsim nyog. Los ntawm kev ua kom ib puag ncig hauv chav ntsuas huv, qhuav, thiab tsis muaj khib nyiab, thiab saib xyuas cov cim qhia ntawm kev hnav, cov neeg ua haujlwm CMM tuaj yeem ua kom lub neej ntev ntawm lawv cov khoom granite thiab tswj qhov tseeb thiab kev ntseeg siab ntawm lawv cov khoom siv ntsuas.
