Hauv siab -kev tsim khoom kawg, kev ua tau zoo ntawm cov khoom ua tau zoo nyob ntawm qhov tsis yog ntawm kev tsim khoom nkaus xwb tab sis kuj yog cov txheej txheem ua haujlwm kom raug. Cov txheej txheem kev thov kev tshawb fawb tuaj yeem txo qhov hnav thiab tsim kua muag, tswj qhov raug ruaj khov, thiab yog li txuas ntxiv kev pabcuam lub neej ntawm cov khoom, ua kom cov khoom txuas ntxiv thiab cov khoom zoo.
Lub hauv paus ntsiab lus tseem ceeb yog kev nkag siab zoo txog cov yam ntxwv ntawm cov khoom. Ua ntej siv, kev tshuaj xyuas cov ntaub ntawv kev kawm yog tsim nyog los qhia meej txog nws cov khoom siv (xws li lub teeb yuag thiab deformability ntawm aluminium alloys, thiab siab hardness thiab brittleness ntawm ceramics), kam rau ua ntau yam, thiab siv tau rau kev khiav hauj lwm (kub, load, ceev, thiab lwm yam). Piv txwv li, siab -precision bearings yuav tsum tsis txhob ua haujlwm rau lub sijhawm ntev tshaj li qhov ntsuas ceev, vim tias lub zog centrifugal tuaj yeem ua rau hnyav dua; thaum cov ceramic substrates tiv taus qhov kub thiab txias, lawv muaj kev cuam tshuam rau micro- tawg los ntawm cua sov thiab cua txias tam sim ntawd. Tsuas yog los ntawm kev sib piv cov xwm txheej ntawm daim ntawv thov tuaj yeem zam qhov kev pheej hmoo ntawm kev siv ntau dhau lossis siv tsis raug.
Kev saib xyuas nruj rau kev nthuav dav yog yuav tsum tau thaum lub sijhawm teeb tsa thiab tso. Precision qhov feem ntau yog cov khoom sib txuas. Ua ntej kev teeb tsa, cov chaw tiv tauj yuav tsum tau muab ntxuav kom tsis txhob muaj qhov sib xyaw ntawm cov khoom uas tuaj yeem ua rau khawb lossis qhov sib txawv ntawm qhov sib txawv. Siv cov cuab yeej pabcuam (xws li nrhiav tus pins lossis elastic grippers) tuaj yeem txo qhov cuam tshuam ntawm daim ntawv thov tsis sib xws. Yog tias tsim nyog, siv lub torque wrench txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tiv thaiv kev ntxhov siab thiab deformation. Rau cov rooj sib txoos uas xav tau kev sib koom ua ke ntau- cov khoom sib koom ua ke (xws li cov iav teeb lossis cov kev taw qhia kev tsheb ciav hlau), qhov sib lawv liag ntawm "tus tswv ua ntej, tom qab ntawd qhev, kauj ruam -los ntawm - kauj ruam calibration" yuav tsum ua raws. Txheeb xyuas qhov tseeb ntawm qhov tseeb ntawm tus txheeb ze siv lub dial taw qhia lossis laser alignment instrument kom ntseeg tau tias coaxiality thiab parallelism ntawm cov khoom txav tau raws li cov qauv.
Kev saib xyuas kev ua haujlwm thiab kev saib xyuas yog qhov tseem ceeb heev rau kev tswj xyuas qhov tseeb tsis tu ncua. Yuav tsum tau tsim ib lub tshuab tshuaj xyuas tsis tu ncua thaum siv txhua hnub los saib xyuas cov suab nrov txawv txav, kev vibrations, lossis qhov kub thiab txias tsis zoo tshwm sim -cov no feem ntau yog cov cim thaum ntxov ntawm hnav lossis xoob. Rau cov zawv zawg qhov chaw (xws li cov lus qhia thiab cov sliders), cov roj nplua nyeem tsim nyog yuav tsum tau muab ntxiv ib ntus kom tsis txhob muaj kev sib txhuam qhuav los ntawm kev ua kom tsis zoo. Rau qhov chaw kis tau tus mob (xws li cov ntsia hlau lead thiab lub sijhawm siv), qhov nro thiab meshing txheej txheem yuav tsum tau kuaj xyuas kom tsis txhob muaj qhov sib txuam ntawm kev sib kis vim yog xoob. Tsis tas li ntawd, nquag pib- nres lub voj voog lossis kev cuam tshuam yuav tsum tau txo qis thaum tsis tsim nyog, vim tias cov xwm txheej no tuaj yeem ua rau lub ntsej muag ncaj ncees thiab ua rau lub neej qaug zog.
Kev tuav tsis raug cai yuav tsum muaj kev xav thiab sijhawm. Yog tias pom qhov sib txawv ntawm qhov tseeb lossis kev ua haujlwm tsis zoo, tsis txhob hloov kho qhov muag tsis pom. Ua ntej, nres lub tshuab thiab tshawb xyuas qhov ua rau (xws li kev teeb tsa tsis raug, kev hloov pauv tam sim ntawd, lossis cuam tshuam ib puag ncig), tom qab ntawd ua cov phiaj xwm kho lossis hloov pauv. Rau cov khoom kho tau zoo (xws li cov lus qhia me ntsis hnav), cov neeg ua haujlwm yuav tsum siv kev sib tsoo, polishing, lossis lwm yam txheej txheem los kho qhov ntev; tus kheej- sib tsoo uas ua rau qhov kev txiav txim siab thawj zaug raug txwv nruj heev.
Kev siv cov khoom precision yog qhov tseem ceeb ntawm "kev nkag siab meej + kev ua haujlwm zoo + kev saib xyuas zoo." Tsuas yog los ntawm kev sib koom ua ke cov kev txawj ntse no rau hauv kev xyaum ua txhua hnub tuaj yeem ua tau zoo tsis tu ncua nyob rau hauv kev ua haujlwm nyuaj, tso ib qho khoom micro- lub hauv paus rau siab - kev loj hlob zoo ntawm kev tsim khoom lag luam.
