Kev siv cov khoom siv granite hauv choj-hom kev sib koom tes ntsuas tshuab (CMMs) tau dhau los ua tus qauv kev lag luam vim lawv cov tshuab zoo heev thiab thermal stability. Granite yog cov khoom siv ntom thiab cov khoom siv nyuaj uas muaj cov coefficient ntawm thermal expansion, ua rau nws cov khoom siv zoo rau kev ntsuas ntsuas kev ntsuas. Txawm li cas los xij, kev hloov pauv kub tseem tuaj yeem cuam tshuam qhov raug thiab ruaj khov ntawm cov khoom siv granite hauv CMMs, thiab nws yog ib qho tseem ceeb kom nkag siab tias cov kev hloov no tuaj yeem cuam tshuam cov txiaj ntsig ntsuas.
Kev hloov kub tuaj yeem ua rau qhov hloov pauv ntawm cov khoom siv granite, uas tuaj yeem cuam tshuam qhov ntsuas qhov tseeb. Thaum qhov kub thiab txias, granite nthuav dav, thiab thaum kub poob, granite sib cog lus, ua rau cov khoom hloov pauv. Qhov no tuaj yeem ua rau qhov tsis raug ntawm kev ntsuas vim qhov kev hloov pauv ntawm qhov kev ncua deb ntawm cov khoom siv thiab cov sensors. Txawm li cas los xij, qhov loj ntawm qhov cuam tshuam ntawm qhov kub hloov pauv nyob ntawm cov khoom siv ntawm granite thiab cov qauv tsim tshwj xeeb ntawm CMM. Ntau lub tuam txhab tau kov yeej qhov kev sib tw no los ntawm kev tsim lawv cov qauv CMM nrog kev sib xyaw ntawm cov ntaub ntawv uas muaj cov coefficients sib txawv ntawm thermal expansion, yog li txo qhov cuam tshuam ntawm qhov kub thiab txias.
Kev hloov kub kuj tuaj yeem cuam tshuam qhov kev ruaj ntseg thiab rov ua dua ntawm CMM. Kev nthuav dav cua sov tuaj yeem ua rau cov neeg kho tshuab drift hauv CMM Cheebtsam, ua rau kev ntsuas tsis raug. Tsis tas li ntawd, kev hloov pauv kub tuaj yeem ua rau granite nto deform, uas ua rau muaj kev hloov pauv hauv qhov profile uas tuaj yeem ua rau kev ntsuas yuam kev. Cov neeg tsim khoom lag luam daws cov teeb meem no los ntawm kev ua haujlwm thermal stabilization nyob rau hauv qhov ntsuas ib puag ncig, ua tib zoo tsim cov qauv CMM kom txo qis thermal expansion thiab drift, thiab xyuas kom meej tias lub tshuab muaj kev ruaj ntseg zoo.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev hloov pauv kub tsis tas yuav muaj qhov tsis zoo rau qhov tseeb ntawm cov khoom siv granite. Thaum hloov qhov kub thiab txias, granite tuaj yeem ua kom ruaj khov dua vim cov txheej txheem ntawm thermally-induced stress nyem. Thaum cov khoom ua kom sov, cov khoom nthuav dav, ua rau kev tso tawm ntawm kev ntxhov siab sab hauv. Cov kev ntxhov siab no tsuas yog tso tawm ib zaug xwb, txhais tau hais tias cov khoom tuaj yeem ruaj khov los ntawm kev ua kom sov rau qhov kub siab.
Hauv kev xaus, thaum qhov kub hloov pauv tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm cov khoom siv granite hauv CMMs, qhov kev cuam tshuam ntawm kev cuam tshuam yog nyob ntawm tus qauv tsim ntawm lub tshuab thiab cov khoom siv tshwj xeeb. Cov neeg tsim khoom yuav tsum coj qhov cuam tshuam ntawm qhov kub thiab txias ntawm lawv cov khoom rau hauv tus account thiab tsim lawv CMMs nyob rau hauv ib txoj kev uas ua kom cov qib siab tshaj plaws ntawm qhov raug thiab ruaj khov. Kev saib xyuas kom zoo thiab ntsuas ntsuas kuj tseem tuaj yeem pab txhawb kev ua haujlwm zoo hauv CMM, thiab nws tseem ceeb heev uas yuav tsum ua raws li cov txheej txheem pom zoo kom txo qis qhov cuam tshuam ntawm qhov kub thiab txias. Los ntawm kev ua raws li cov lus qhia no, cov neeg siv tuaj yeem tso siab rau qhov raug thiab ruaj khov ntawm lawv cov granite-based CMM systems.
