Granite yog ib yam khoom siv feem ntau siv rau hauv cov qauv ntsuas sib koom tes (CMM) vim nws ruaj khov zoo heev thiab tiv taus qhov kub thiab txias hloov pauv. Qhov tseeb ntawm kev ntsuas tag nrho ntawm CMM raug cuam tshuam los ntawm ntau yam tseem ceeb, thiab kev xaiv granite ua cov khoom siv hauv tsev ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau tias kev ntsuas raug thiab txhim khu kev qha.
Ib qho ntawm cov yam tseem ceeb uas cuam tshuam rau qhov kev ntsuas qhov tseeb ntawm CMM yog qhov ruaj khov ntawm lub tshuab. Granite muaj qhov ceev ceev thiab qhov coefficient qis ntawm thermal expansion, muab lub hauv paus ruaj khov thiab khov kho rau CMMs. Qhov kev ruaj khov no txo cov teebmeem ntawm kev co thiab kev hloov pauv thermal uas tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ntsuas. Tsis tas li ntawd, cov khoom siv damping ntuj ntawm granite pab txo qhov cuam tshuam ntawm kev cuam tshuam sab nraud, txhim kho qhov tseeb ntawm kev ntsuas.
Lwm yam tseem ceeb yog qhov ruaj khov ntawm cov khoom CMM. Granite qhia txog qhov hloov pauv me me ntawm lub sijhawm, ua kom lub tshuab tswj tau nws qhov tseeb thiab rov ua dua tau ntev. Qhov no yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev ntsuas sib xws thiab txhim khu kev qha.
Qhov zoo ntawm cov granite siv rau hauv CMM kev tsim kho kuj tseem ceeb heev rau kev ntsuas qhov tseeb. Cov nplaim du thiab tiaj tus yog qhov tseem ceeb rau kev teeb tsa cov txheej txheem ntsuas thiab cov khoom siv kom raug, nrog rau kev txav mus los ntawm cov tshuab axes. Cov nplaim granite zoo pab txhawb rau qhov tseeb ntawm CMM.
Tsis tas li ntawd xwb, kev tsim thiab kev tsim cov khoom CMM xws li cov hlau qhia thiab cov kabmob cua tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ntsuas tag nrho. Kev sib dhos thiab kev ntsuas kom zoo ntawm cov khoom no, nrog rau kev ruaj khov los ntawm lub hauv paus granite, yog qhov tseem ceeb rau kev ua tiav qhov kev ntsuas kom raug thiab rov ua dua.
Hauv kev xaus, kev xaiv granite ua cov khoom siv rau CMM yog qhov tseem ceeb hauv kev ua kom muaj kev ntsuas siab. Nws qhov kev ruaj khov, qhov ntev, qhov zoo ntawm qhov chaw thiab cov khoom damping tag nrho pab txhawb rau qhov tseeb thiab kev ntseeg siab ntawm lub tshuab. Thaum ua ke nrog cov khoom tsim thiab calibrated zoo, granite ua lub luag haujlwm tseem ceeb hauv kev ua tiav cov kev ntsuas meej hauv ntau yam kev lag luam thiab kev siv metrology.
