Kev siv cov khoom granite hauv Coordinate Measuring Machines (CMM) yog ib qho kev coj ua zoo hauv kev lag luam tsim khoom. Granite yog pob zeb uas tshwm sim ntuj uas muaj cov khoom zoo heev xws li thermal stability, coefficient qis ntawm thermal expansion, thiab siab stiffness. Cov khoom no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv kev tsim cov cuab yeej ntsuas rhiab xws li CMMs. Cov khoom no ua kom muaj kev ntsuas siab uas tseem ceeb rau kev lag luam tsim khoom.
Kev ruaj khov ntawm thermal yog ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm granite. CMMs yog cov cuab yeej precision uas yuav tsum ruaj khov txawm tias muaj qhov kub hloov pauv. Kev siv granite ua cov khoom siv tsim kho kom ntseeg tau tias lub tshuab tseem ruaj khov, txawm tias qhov kub hloov pauv li cas los xij. Tus coefficient ntawm thermal expansion ntawm granite yog qis, uas ua kom ntseeg tau tias txhua qhov thermal expansion yog tsawg kawg nkaus, tso cai rau kev ntsuas kom nyob ruaj khov ntawm ntau qhov kub ua haujlwm. Cov yam ntxwv no yog qhov tseem ceeb rau qhov tseeb ntawm kev ntsuas los ntawm CMMs.
Qhov coefficient qis ntawm thermal expansion ntawm granite ua kom ntseeg tau tias cov kev ntsuas uas CMMs coj los tseem raug txawm tias muaj kev hloov pauv kub. Kev hloov pauv kub tuaj yeem cuam tshuam rau qhov loj me thiab cov duab ntawm cov khoom uas raug ntsuas. Txawm li cas los xij, kev siv granite ua cov khoom siv rau CMMs ua kom ntseeg tau tias txhua qhov kev hloov pauv kub tsis cuam tshuam rau qhov tseeb ntawm kev ntsuas. Cov cuab yeej no yog qhov tseem ceeb hauv kev lag luam tsim khoom, qhov twg qhov tseeb yog qhov tseem ceeb hauv kev ua kom cov khoom tiav ua tau raws li cov neeg siv khoom cov lus qhia.
Qhov ruaj khov siab yog lwm yam tseem ceeb uas ua rau granite yog cov khoom siv zoo tagnrho rau CMMs. Cov khoom siv hauv CMMs yuav tsum ruaj khov los txhawb cov khoom ntsuas, uas feem ntau yog qhov ntsuas rhiab heev. Kev siv granite ua kom lub tshuab tseem ruaj khov, txo qhov kev hloov pauv los ntawm qhov hnyav ntawm cov khoom ntsuas. Cov khoom no ua kom ntseeg tau tias qhov ntsuas ntsuas txav mus raws li peb txoj kab (x, y, thiab z) uas xav tau los ntsuas kom raug.
Kev siv granite hauv CMM kev tsim kho kuj ua kom lub tshuab ruaj khov rau lub sijhawm ntev. Granite yog cov khoom siv ntom ntom, tawv uas tsis warp, khoov, lossis sag dhau sijhawm. Cov khoom no ua kom lub tshuab khaws nws qhov tseeb thiab qhov tseeb ntau xyoo ntawm kev ua haujlwm. Tsis tas li ntawd, granite tiv taus kev hnav thiab tsim kua muag, txhais tau tias nws xav tau kev saib xyuas tsawg kawg nkaus, txo lub sijhawm tsis ua haujlwm thiab ua kom lub tshuab ua haujlwm ntev dua.
Xaus lus, kev siv granite hauv CMM kev tsim kho yog qhov tseem ceeb hauv kev ua kom muaj kev ntsuas siab hauv kev lag luam tsim khoom. Cov khoom tshwj xeeb ntawm granite, xws li thermal stability, coefficient qis ntawm thermal expansion, thiab siab stiffness, ua kom lub tshuab tseem raug txawm tias muaj qhov kub thiab txias hloov pauv. Tsis tas li ntawd, granite lub zog thiab kev tiv thaiv kev hnav ua kom lub tshuab khaws nws qhov tseeb ntau xyoo ntawm kev ua haujlwm. Zuag qhia tag nrho, kev siv granite hauv CMMs yog kev nqis peev zoo hauv kev ua kom muaj txiaj ntsig zoo thiab zoo hauv kev lag luam tsim khoom.
