Granite yog ib yam khoom siv dav dav hauv kev tsim cov tshuab ntsuas sib koom ua ke (CMM) vim nws cov khoom siv lub cev zoo heev. CMMs yog cov cuab yeej tseem ceeb siv hauv ntau yam lag luam rau kev ntsuas geometry ntawm cov duab thiab qhov chaw nyuaj. Cov CMMs siv hauv kev tsim khoom thiab cov txheej txheem tsim khoom xav tau lub hauv paus meej thiab ruaj khov kom tswj tau qhov tseeb thiab rov ua dua ntawm kev ntsuas. Granite, ib hom pob zeb igneous, yog ib yam khoom zoo tagnrho rau daim ntawv thov no vim nws muaj kev ruaj khov zoo heev, kev ruaj khov thermal siab, thiab cov coefficients nthuav dav thermal qis.
Kev tawv yog ib qho tseem ceeb uas yuav tsum muaj rau lub platform ntsuas ruaj khov, thiab granite muab kev tawv zoo dua piv rau lwm cov ntaub ntawv, xws li hlau lossis hlau. Granite yog cov khoom siv ntom ntom, tawv thiab tsis muaj qhov, uas txhais tau tias nws tsis deform thaum lub sijhawm thauj khoom, ua kom ntseeg tau tias lub platform ntsuas CMM khaws nws cov duab txawm tias nyob hauv ntau yam kev thauj khoom. Qhov no ua kom ntseeg tau tias cov kev ntsuas tau ua yog qhov tseeb, rov ua dua, thiab taug qab tau.
Kev ruaj khov ntawm thermal yog lwm yam tseem ceeb hauv kev tsim cov CMMs. Granite muaj cov coefficient thermal expansion qis vim nws cov qauv molecular thiab qhov ceev. Yog li ntawd, nws ruaj khov heev ntawm ntau qhov kub thiab qhia txog kev hloov pauv me me vim muaj qhov kub sib txawv. Cov qauv Granite muaj cov coefficient qis ntawm thermal expansion, uas ua rau nws tiv taus thermal distortion heev. Raws li kev lag luam cuam tshuam nrog ntau yam khoom thiab daim ntawv thov uas ua haujlwm ntawm ntau qhov kub sib txawv, kev siv granite hauv kev tsim CMMs ua kom ntseeg tau tias kev ntsuas tau ua tiav raug, tsis hais qhov kub hloov pauv li cas.
Qhov ruaj khov ntawm granite yog sib xws, txhais tau tias nws nyob hauv nws cov duab thiab daim ntawv qub, thiab nws qhov nyuaj tsis hloov pauv raws sijhawm. Qhov no ua kom ntseeg tau tias cov khoom granite ntawm CMM muab lub hauv paus ruaj khov thiab kwv yees tau rau cov khoom txav mus los ntawm cov cuab yeej ntsuas. Nws ua rau lub kaw lus tsim cov kev ntsuas raug thiab nyob twj ywm calibrated dhau sijhawm, tsis tas yuav rov kho dua ntau zaus.
Tsis tas li ntawd xwb, granite kuj ruaj khov heev, yog li nws tuaj yeem tiv taus kev siv CMM ntau dhau sijhawm, uas ua rau nws muaj peev xwm ntsuas tau meej thiab txhim khu kev qha rau lub sijhawm ntev. Granite kuj tsis yog hlau nplaum, uas yog qhov zoo tseem ceeb hauv kev siv hauv kev lag luam uas cov teb hlau nplaum tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ntsuas.
Hauv kev xaus, granite yog siv dav hauv kev tsim cov tshuab ntsuas kev sib koom tes vim nws qhov kev tawv nqaij tshwj xeeb, kev ruaj khov thermal, thiab qhov ntev sib xws dhau sijhawm. Cov yam no ua rau CMM muab qhov tseeb, rov ua dua, thiab taug qab cov duab nyuaj siv hauv ntau yam kev tsim khoom thiab cov txheej txheem ntau lawm. Kev siv granite hauv kev tsim cov CMMs ua kom muaj kev ntsuas zoo rau kev lag luam txhim khu kev qha thiab muaj txiaj ntsig zoo dua.
