Cov tshuab ntsuas peb-coordinate (CMMs) yog cov khoom siv dav dav thoob plaws ntau yam kev lag luam tsim khoom los ntsuas qhov loj me, geometry, thiab qhov chaw ntawm cov qauv 3D nyuaj. Qhov tseeb thiab kev ntseeg tau ntawm cov tshuab no yog qhov tseem ceeb rau kev ua kom zoo ntawm cov khoom kawg, thiab ib qho tseem ceeb uas pab txhawb rau lawv cov kev ua tau zoo yog lub hauv paus tseem ceeb uas yog lub hauv paus ntawm cov txheej txheem ntsuas: lub phaj granite.
Granite paub txog nws cov khoom zoo heev, suav nrog nws qhov siab tawv, qis coefficient ntawm thermal expansion, thiab zoo heev damping peev xwm. Cov yam ntxwv no ua rau nws yog cov khoom zoo tagnrho rau CMMs, uas xav tau lub hauv paus ruaj khov thiab nruj los txhawb lawv cov ntsuas probes thiab muab cov ntaub ntawv tseeb thiab sib xws. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov zoo ntawm granite ua lub hauv paus tseem ceeb ntawm CMMs thiab nws pab txhawb rau lawv cov kev ua tau zoo li cas.
1. Kev Ruaj Khoov: Granite muaj Young's modulus siab heev, uas txhais tau tias nws tiv taus kev hloov pauv thaum raug kev ntxhov siab. Qhov kev ruaj khov no ua kom lub phaj granite tseem tiaj tus thiab ruaj khov nyob rau hauv qhov hnyav ntawm cov qauv lossis qhov ntsuas ntsuas, tiv thaiv txhua qhov kev hloov pauv tsis xav tau uas yuav ua rau qhov tseeb ntawm kev ntsuas tsis zoo. Qhov kev ruaj khov siab ntawm granite kuj tso cai rau CMMs kom raug tsim nrog cov phaj granite loj dua, uas ua rau muaj chaw ntau dua rau cov khoom loj dua thiab cov qauv geometries nyuaj dua.
2. Kev ruaj khov ntawm thermal: Granite muaj cov coefficient qis heev ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus ntau thaum raug rau kev hloov pauv ntawm qhov kub thiab txias. Cov khoom no yog qhov tseem ceeb rau CMMs txij li thaum muaj kev hloov pauv ntawm qhov loj ntawm lub phaj nto vim yog kev hloov pauv ntawm qhov kub thiab txias yuav ua rau muaj qhov yuam kev hauv kev ntsuas. Cov phaj nto granite tuaj yeem muab kev ntsuas ruaj khov thiab txhim khu kev qha txawm tias nyob rau hauv ib puag ncig uas qhov kub thiab txias hloov pauv tseem ceeb, xws li cov chaw tsim khoom lossis cov chaw kuaj mob.
3. Lub peev xwm ua kom tsis txhob co: Granite muaj peev xwm tshwj xeeb los nqus cov kev co thiab tiv thaiv lawv kom tsis txhob cuam tshuam rau kev ntsuas. Kev co tuaj yeem los ntawm ntau qhov chaw xws li kev co tshuab, kev siv tshuab, lossis kev ua ub no ntawm tib neeg ze ntawm CMM. Lub peev xwm ua kom tsis txhob co ntawm granite pab txo qhov cuam tshuam ntawm kev co thiab xyuas kom meej tias lawv tsis tsim suab nrov lossis kev ntsuas yuam kev. Cov cuab yeej no yog qhov tseem ceeb tshwj xeeb thaum cuam tshuam nrog cov khoom rhiab heev thiab mos lossis thaum ntsuas ntawm qib siab.
4. Kev Ruaj Khov: Granite yog ib yam khoom siv uas ruaj khov thiab siv tau ntev uas siv tau ntev thiab siv tsis tau zoo hauv kev lag luam. Nws tiv taus khawb, xeb, thiab hnav thiab tsim kua muag, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau ib qho khoom uas yuav tsum muab kev ntsuas ruaj khov thiab raug rau lub sijhawm ntev. Cov phaj granite xav tau kev saib xyuas tsawg kawg nkaus thiab tuaj yeem kav ntev li ntau xyoo, muab kev nqis peev mus sij hawm ntev hauv CMM.
5. Yooj yim ntxuav: Granite yooj yim ntxuav thiab tswj, ua rau nws yog qhov kev xaiv zoo rau kev siv hauv kev lag luam. Nws qhov chaw tsis muaj qhov ntxeem tau tiv taus cov dej noo thiab cov kab mob loj hlob, txo qhov kev pheej hmoo ntawm kev ua qias tuaj thiab xyuas kom meej tias qhov ntsuas tau zoo. Cov phaj granite tuaj yeem ntxuav tau sai nrog dej thiab xab npum thiab tsis tas siv zog ntau los khaws cia kom zoo.
Xaus lus, granite ua lub hauv paus tseem ceeb ntawm CMMs muab cov txiaj ntsig zoo uas pab txhawb rau lawv cov kev ua tau zoo thiab kev ntseeg siab. Qhov tawv, thermal stability, damping peev xwm, durability, thiab yooj yim ntawm kev ntxuav ua rau granite yog qhov kev xaiv zoo tshaj plaws rau ib qho khoom uas yuav tsum muab cov kev ntsuas tseeb thiab sib xws hauv qab ntau yam mob. CMMs ua nrog granite nto phaj muaj zog dua, ruaj khov dua, thiab raug dua, muab kev ntseeg siab thiab kev meej meej uas xav tau los tsim cov khoom zoo.
