Peb-coordinate Measuring Machines (CMMs) yog cov cuab yeej muaj tseeb, meej thiab txhim khu kev qha uas siv ntau yam kev lag luam rau kev ntsuas qhov ntev. Qhov tseeb thiab ruaj khov ntawm CMMs nyob ntawm ntau yam ntawm cov ntaub ntawv siv hauv lawv cov kev tsim kho, thiab ib qho ntawm cov khoom siv nrov tshaj plaws rau lub hom phiaj no yog granite.
Granite yog lub pob zeb ntuj uas paub txog nws cov khoom zoo heev. Nws muaj zog, ruaj khov, thiab tsis tshua muaj thermal expansion, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau CMMs. Qhov tseeb thiab ruaj khov ntawm granite Cheebtsam hauv CMM raug cuam tshuam ncaj qha los ntawm kev hloov pauv kub. Hauv tsab xov xwm no, peb yuav tham txog yuav ua li cas hloov qhov kub thiab txias cuam tshuam rau granite Cheebtsam 'qhov tseeb thiab ruaj khov hauv CMM.
Granite Cheebtsam thiab kub hloov pauv
Granite Cheebtsam hauv CMMs feem ntau yog ua los ntawm dub granite, uas yog ib qho tawv, ruaj, thiab ntom daim ntawv ntawm granite. Nws qhov siab ceev thiab qis thermal expansion coefficients ua rau nws tsim nyog siv rau hauv kev tsim kho ntawm CMMs. Txawm li cas los xij, txawm tias dub granite muaj cov cuab yeej zoo heev, nws tseem cuam tshuam los ntawm kev hloov pauv hauv qhov kub thiab txias.
Kev hloov pauv kub uas tshwm sim hauv ib puag ncig ntawm CMM ncaj qha cuam tshuam rau cov khoom siv granite 'qhov tseeb thiab ruaj khov. Qhov kub thiab txias hloov ua rau muaj kev ntxhov siab thiab cov kab mob ntawm cov khoom siv granite, uas tuaj yeem ua rau cov khoom deformation thiab ua rau muaj kev ntsuas tsis raug.
Qhov cuam tshuam ntawm qhov kub thiab txias hloov ntawm qhov tseeb
Granite yog cov khoom siv uas tsis tshua muaj thermal expansion coefficient, uas txhais tau hais tias nws hloov me ntsis hauv qhov loj me thaum raug kev hloov pauv hauv qhov kub thiab txias. Txawm li cas los xij, vim tias CMMs xav tau kev ntsuas qhov tseeb thiab meej, txawm tias kev hloov pauv me me hauv cov khoom siv granite 'loj tuaj yeem cuam tshuam rau lawv qhov raug.
Thaum qhov kub hloov pauv tshwm sim, qhov ntsuas tau muab los ntawm CMM yuav tsis raug, thiab qhov ntsuas yuav tsis rov ua dua. Qhov no tshwm sim vim hais tias cov khoom siv granite nthuav dav lossis cog lus ntawm tus nqi sib txawv, ua rau muaj kev hloov pauv ntawm lub tshuab ua haujlwm.
Qhov cuam tshuam ntawm qhov kub thiab txias hloov ntawm kev ruaj ntseg
Kev ruaj ntseg yog hais txog lub peev xwm ntawm CMM los tswj nws qhov raug raws sij hawm, txawm tias ib puag ncig. Kev hloov kub tuaj yeem cuam tshuam qhov ruaj khov ntawm cov khoom siv granite hauv CMM. Thaum qhov kub ntawm ib puag ncig hloov pauv, cov khoom siv granite yuav nthuav dav lossis cog lus, ua rau muaj kev ntxhov siab hauv cov khoom siv. Sij hawm dhau mus, qhov rov tshwm sim ntawm qhov kub thiab txias hloov yuav ua rau granite poob nws qhov kev ruaj ntseg, thiab CMM qhov tseeb yuav raug cuam tshuam.
Ua kom Granite Cheebtsam ruaj khov thiab raug
Txhawm rau kom ntseeg tau tias cov khoom siv granite hauv CMM nyob ruaj khov thiab raug, nws yog qhov tseem ceeb los tswj qhov kub ntawm ib puag ncig ntawm lub tshuab. Ib txoj hauv kev kom ua tiav qhov no yog los ntawm kev ua kom CMM nyob rau hauv ib puag ncig kev tswj hwm, qhov twg qhov kub thiab txias yuav tsum tsis tu ncua. Lwm qhov kev xaiv yog siv cov tshuab ntsuas kub uas yuav tswj tau qhov kub thiab txias tsis tu ncua hauv CMM.
Kev tuav tswj kom raug thiab kev saib xyuas ntawm CMM kuj tseem ceeb hauv kev ua kom nws ruaj khov thiab raug mus ntev. Kev tuav lub CMM nrog kev saib xyuas thiab ua raws li cov chaw tsim khoom cov lus qhia rau kev saib xyuas yuav pab tiv thaiv kev ua yuam kev los ntawm kev hloov kub.
Xaus
Granite Cheebtsam siv hauv CMMs yog qhov tseem ceeb rau lub tshuab kom raug thiab ruaj khov. Lawv muaj zog, ruaj, thiab muaj thermal expansion coefficients tsawg, ua rau lawv zoo tagnrho rau daim ntawv thov no. Txawm li cas los xij, qhov kub thiab txias hloov ntawm ib puag ncig ntawm lub tshuab tuaj yeem cuam tshuam rau cov khoom siv granite 'qhov tseeb thiab ruaj khov, ua rau kev ntsuas tsis raug.
Thaum tswj qhov kub thiab txias ib puag ncig yog qhov tseem ceeb rau kev ua kom cov khoom siv granite ruaj khov thiab raug, kev tuav thiab kev saib xyuas kom zoo kuj tseem ceeb. Los ntawm kev saib xyuas cov khoom tseem ceeb no, cov neeg siv tuaj yeem ua kom lawv cov CMMs nyob ruaj khov thiab raug rau xyoo tom ntej.
