Choj CMM (Coordinate Measuring Machine) yog ib lub cuab yeej ntsuas siab uas muaj cov qauv zoo li choj uas txav mus raws peb txoj kab orthogonal los ntsuas qhov loj ntawm ib yam khoom. Txhawm rau kom paub tseeb tias muaj tseeb hauv kev ntsuas, cov khoom siv siv los tsim cov khoom CMM ua lub luag haujlwm tseem ceeb. Ib qho khoom siv zoo li no yog granite. Hauv tsab xov xwm no, peb yuav tham txog qhov cuam tshuam tshwj xeeb ntawm cov khoom granite rau qhov tseeb ntawm Choj CMM.
Granite yog ib lub pob zeb ntuj uas muaj cov yam ntxwv tshwj xeeb uas ua rau nws yog cov khoom siv zoo tshaj plaws rau cov khoom siv Choj CMM. Nws yog qhov ntom, muaj zog, thiab muaj kev ruaj khov zoo heev. Cov yam ntxwv no tso cai rau cov khoom siv los tiv taus kev co, kev hloov pauv thermal, thiab lwm yam kev cuam tshuam ib puag ncig uas tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ntsuas.
Muaj ntau yam khoom siv granite siv rau hauv kev tsim kho Choj CMM, suav nrog cov granite dub, liab dawb, thiab grey. Txawm li cas los xij, cov granite dub yog cov khoom siv feem ntau siv vim nws qhov ceev ceev thiab cov coefficient thermal expansion qis.
Qhov cuam tshuam tshwj xeeb ntawm cov khoom granite rau qhov tseeb ntawm Choj CMM tuaj yeem sau ua ke raws li hauv qab no:
1. Kev Ruaj Ntseg: Cov khoom siv granite muab kev ruaj ntseg zoo heev uas ua kom muaj kev ntsuas tseeb thiab rov ua dua. Kev ruaj ntseg ntawm cov khoom siv tso cai rau CMM kom tswj nws txoj haujlwm thiab kev taw qhia yam tsis hloov pauv, tsis hais txog kev hloov pauv ib puag ncig hauv qhov kub thiab txias thiab kev co.
2. Kev Ruaj Khoov: Granite yog ib yam khoom tawv uas tuaj yeem tiv taus kev khoov thiab kev sib ntswg. Kev tawv ntawm cov khoom tshem tawm qhov kev hloov pauv, uas yog kev khoov ntawm CMM cov khoom hauv qab kev thauj khoom. Cov cuab yeej no ua kom ntseeg tau tias lub txaj CMM tseem sib luag rau cov kab sib koom ua ke, muab kev ntsuas tseeb thiab sib xws.
3. Cov khoom siv los ua kom cov av noo: Granite muaj cov khoom siv los ua kom cov av noo zoo heev uas txo cov kev co thiab tshem tawm lub zog. Cov khoom no ua kom ntseeg tau tias cov khoom CMM nqus tau txhua qhov kev co los ntawm kev txav ntawm cov probes, ua rau muaj kev ntsuas tseeb thiab raug.
4. Cov coefficient thermal expansion qis: Granite muaj cov coefficient thermal expansion qis piv rau lwm cov ntaub ntawv xws li txhuas thiab hlau. Cov coefficient qis no ua kom CMM tseem ruaj khov rau ntau qhov kub thiab txias, muab kev ntsuas sib xws thiab raug.
5. Kev Ruaj Khov: Granite yog ib yam khoom siv ruaj khov uas tuaj yeem tiv taus kev hnav thiab tsim kua muag los ntawm kev siv tas li. Kev ruaj khov ntawm cov khoom siv ua kom ntseeg tau tias cov khoom CMM tuaj yeem siv tau ntev, ua kom ntseeg tau tias muaj kev ntseeg siab thiab raug ntawm kev ntsuas.
Xaus lus, kev siv cov khoom granite hauv Choj CMM muaj feem cuam tshuam loj rau qhov tseeb ntawm kev ntsuas. Cov khoom siv ruaj khov, tawv, cov khoom damping, cov coefficient thermal expansion qis, thiab kev ua haujlwm ntev ua kom CMM tuaj yeem muab cov kev ntsuas raug thiab rov ua dua tau ntev. Yog li ntawd, kev xaiv Choj CMM nrog cov khoom granite yog kev nqis peev zoo rau cov tuam txhab uas xav tau kev ntsuas meej thiab raug hauv lawv cov txheej txheem ntau lawm.
