Kev siv cov khoom granite yog ib feem tseem ceeb ntawm kev ua haujlwm ntawm Coordinate Measuring Machines (CMM). Raws li cov khoom siv ruaj khov uas muaj peev xwm tiv taus qhov nyuaj ntawm kev ntsuas, granite yog qhov kev xaiv khoom zoo meej rau nws cov qauv kev ruaj khov, kev nthuav dav thermal tsawg, thiab kev tawv ncauj siab. Qhov chaw teeb tsa thiab kev taw qhia ntawm cov khoom granite hauv CMM yog cov yam tseem ceeb uas cuam tshuam loj heev rau qhov tseeb ntawm kev ntsuas.
Ib lub luag haujlwm tseem ceeb ntawm cov khoom granite hauv CMM yog los muab lub hauv paus ruaj khov rau lub tshuab ua cov haujlwm ntsuas. Yog li ntawd, qhov chaw teeb tsa thiab kev taw qhia ntawm cov khoom granite yuav tsum yog qhov tseeb, sib npaug, ruaj khov, thiab sib dhos kom raug kom ntseeg tau tias muaj kev nyeem ntawv raug. Kev tso cov khoom granite rau hauv qhov chaw raug pab txo cov yam ntxwv ib puag ncig uas yuav ua rau muaj qhov yuam kev ntsuas. CMM yuav tsum tau teeb tsa rau hauv ib puag ncig tswj hwm kom txo qhov cuam tshuam ntawm cov khoom sab nraud rau ntawm cov txheej txheem ntsuas.
Qhov kev taw qhia ntawm cov khoom granite hauv CMM yog lwm yam tseem ceeb uas cuam tshuam rau qhov tseeb ntawm kev ntsuas. Qhov kev taw qhia ntawm cov khoom granite nyob ntawm qhov chaw ntawm txoj haujlwm ntsuas hauv lub tshuab. Yog tias txoj haujlwm ntsuas poob rau ntawm ib txoj kab ntawm lub tshuab, cov khoom granite ntawm qhov kev taw qhia ntawd yuav tsum tau taw qhia txaus kab rov tav kom ntseeg tau tias lub ntiajteb txawj nqus ua haujlwm tawm tsam kev txav mus los ntawm lub tshuab. Qhov kev taw qhia no txo qhov yuam kev los ntawm lub zog gravitational drift. Tsis tas li ntawd, kev teeb tsa cov khoom granite raws txoj kab ntawm kev txav mus los ua kom ntseeg tau tias kev txav mus los tsis muaj lwm yam sab nraud.
Qhov chaw ntawm cov khoom granite hauv CMM kuj tseem ceeb heev rau kev ua tiav qhov ntsuas tseeb. Cov khoom yuav tsum tau teeb tsa rau hauv tus qauv uas txo cov teebmeem ntawm kev hloov pauv ntawm lub tshuab. Kev tso cov khoom granite rau ntawm qhov chaw ntawm lub tshuab yuav tsum sib npaug thiab sib npaug. Thaum lub nra hnyav raug faib sib npaug rau ntawm qhov chaw, lub thav duab ntawm lub tshuab oscillates hauv tus qauv symmetrical tshem tawm kev hloov pauv.
Lwm yam uas cuam tshuam rau qhov chaw teeb tsa thiab kev taw qhia ntawm cov khoom granite yog qhov nthuav dav ntawm cov khoom siv. Granite muaj cov coefficient thermal ntawm kev nthuav dav; yog li, nws nthuav dav thaum kub nce. Qhov kev nthuav dav no tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ntsuas yog tias tsis tau them rov qab txaus. Txhawm rau kom txo qis cov teebmeem ntawm kev nthuav dav thermal ntawm kev ntsuas, nws yog qhov tseem ceeb rau kev teeb tsa lub tshuab hauv chav tswj kub. Tsis tas li ntawd, cov khoom granite yuav tsum tau txo qis kev ntxhov siab, thiab lub moj khaum teeb tsa yuav tsum tau teeb tsa rau hauv txoj hauv kev uas them rov qab rau cov teebmeem thermal ntawm lub tshuab.
Qhov chaw teeb tsa thiab kev teeb tsa ntawm cov khoom granite hauv CMM muaj feem cuam tshuam loj heev rau kev ua haujlwm ntawm lub tshuab. Nws yog ib qho tseem ceeb uas yuav tsum ua qhov kev kuaj xyuas qhov tseeb ntawm lub tshuab kom txo qhov yuam kev thiab tswj qhov tseeb ntawm kev ntsuas. Kev kho qhov system kuj tseem yuav tsum tau ua kom kho qhov yuam kev ntawm qhov system.
Xaus lus, qhov chaw teeb tsa thiab kev taw qhia ntawm cov khoom granite hauv CMM ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub tshuab. Kev teeb tsa kom zoo yuav tshem tawm cov teebmeem ntawm cov yam sab nraud thiab ua rau muaj kev ntsuas raug. Kev siv cov khoom granite zoo, kev teeb tsa kom zoo, kev ntsuas kom raug, thiab kev kuaj xyuas qhov tseeb tsis tu ncua ua kom ntseeg tau tias qhov ntsuas raug ntawm CMM.
