Cov khoom siv granite siv dav hauv kev lag luam tsim khoom vim lawv muaj kev ruaj khov thiab raug. Cov tshuab ntsuas peb-coordinate (CMM) yog ib qho ntawm ntau yam cuab yeej tsim khoom uas siv cov khoom granite. Kev siv cov khoom granite hauv CMMs lav qhov ntsuas raug vim lawv cov khoom ntuj xws li kev ruaj khov siab, kev ruaj khov, thiab kev ruaj khov thermal. Cov khoom no ua rau cov khoom granite zoo tagnrho rau cov tshuab ntsuas uas xav tau qhov tseeb siab thiab kev ntsuas raug.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov khoom granite hauv CMMs yog lawv txoj kev tiv thaiv kev hnav. Granite yog ib lub pob zeb ntuj tsim uas ruaj khov thiab ruaj khov thiab paub zoo txog nws lub zog thiab kev tiv thaiv kev hnav. Cov khoom granite siv hauv CMMs tuaj yeem tiv taus cov xwm txheej ua haujlwm hnyav, suav nrog kev co thiab kev nyuaj siab, yam tsis muaj cov cim qhia ntawm kev hnav lossis kev hloov pauv. Kev tiv thaiv kev hnav ntawm cov khoom granite ua kom ntseeg tau tias lawv tsis tas yuav hloov pauv tas li, uas thaum kawg txo cov nqi txij nkawm thiab ua kom lub sijhawm ua haujlwm siab tshaj plaws.
Tsis tas li ntawd xwb, cov khoom granite tsis tas yuav kho ntau. Lawv tsis tas yuav kho ntau, thiab yog tias koj saib xyuas zoo thiab ntxuav tas li, lawv tuaj yeem ua kom raug thiab meej rau ntau xyoo. Kev siv cov khoom granite hauv CMMs lav tias lub tshuab ua kom raug, uas ua rau muaj qhov yuam kev tsawg dua thiab cov txiaj ntsig rov ua dua zoo dua.
Ntxiv rau qhov tsis kam hnav thiab ruaj khov zoo heev, cov khoom granite muab kev tiv thaiv ntuj tsim rau kev hloov pauv los ntawm qhov kub thiab txias. Qhov coefficient qis ntawm thermal expansion (CTE) ntawm granite ua kom ntseeg tau tias qhov tseeb ntawm kev ntsuas tseem zoo ib yam tsis hais qhov kub thiab txias hauv qhov chaw ua haujlwm. Qhov CTE qis ua rau granite zoo tagnrho rau kev siv hauv CMMs uas xav tau cov txheej txheem ntsuas meej thiab ruaj khov zoo heev.
Xaus lus, kev siv cov khoom granite hauv CMMs lav qhov tseeb thiab ruaj khov, thiab qhov xav tau hloov pauv tsawg heev. Qhov tsis kam hnav, kev saib xyuas tsawg, thiab kev tiv thaiv ntuj tsim rau kev hloov pauv los ntawm qhov kub thiab txias ua rau cov khoom granite zoo tagnrho rau kev siv hauv CMMs, thiab ntau lwm yam lag luam uas xav tau cov txheej txheem tsim khoom siab. Cov txiaj ntsig ntawm cov khoom granite hauv CMMs suav nrog kev ua haujlwm zoo, kev tswj xyuas zoo dua, thiab txo lub sijhawm tsis ua haujlwm, thaum kawg ua rau muaj kev tsim khoom zoo dua thiab muaj txiaj ntsig zoo dua.
