Qhov Tseeb thiab Kev Ntseeg Tau ntawm Granite Rulers
Thaum nws los txog rau kev ntsuas qhov tseeb hauv ntau qhov chaw xws li kev tsim kho vaj tse, kev ua haujlwm ntoo, thiab kev ua haujlwm hlau, qhov tseeb thiab kev ntseeg tau ntawm cov cuab yeej yog qhov tseem ceeb. Ntawm cov cuab yeej no, cov ntsuas granite sawv tawm rau lawv qhov kev ua tau zoo tshwj xeeb. Ua los ntawm cov granite khov kho, cov ntsuas no tsis yog tsuas yog ruaj khov tab sis kuj muab qib kev ntsuas uas nyuaj rau sib phim.
Cov ntsuas granite muaj npe nrov rau lawv qhov ruaj khov thiab tiv taus kev warping, uas yog ib qho teeb meem feem ntau nrog cov cuab yeej ntsuas ntoo lossis yas. Qhov kev ruaj khov no ua kom ntseeg tau tias kev ntsuas tseem sib xws dhau sijhawm, ua rau cov ntsuas granite yog qhov kev xaiv zoo rau cov kws tshaj lij uas xav tau qhov tseeb hauv lawv txoj haujlwm. Cov khoom muaj nqis ntawm granite, suav nrog nws qhov ceev thiab qhov nyuaj, pab txhawb rau nws qhov kev ntseeg tau, tso cai rau nws kom tiv taus qhov nyuaj ntawm ib puag ncig kev cob qhia yam tsis poob nws qhov tseeb.
Ib qho ntawm cov yam ntxwv tseem ceeb uas ua rau cov granite rulers raug yog lawv cov npoo uas tau calibrated zoo. Cov npoo no feem ntau raug sib tsoo rau qib siab ntawm kev raug, tso cai rau kev ntsuas meej thiab raug. Tsis tas li ntawd, ntau cov granite rulers tuaj nrog cov cim etched uas tiv taus hnav, xyuas kom meej tias cov kev ntsuas tseem nyeem tau txawm tias tom qab siv ntev. Qhov kev ruaj khov no yog qhov tseem ceeb rau kev tswj hwm kev ntseeg tau hauv ntau yam kev siv, los ntawm kev ua haujlwm layout mus rau cov haujlwm machining nyuaj.
Tsis tas li ntawd xwb, cov kav granite feem ntau siv ua ke nrog lwm cov cuab yeej ntsuas qhov tseeb, xws li calipers thiab micrometers, kom ua tiav qhov tseeb dua. Lawv cov chaw tiaj tiaj muab qhov chaw siv tau zoo, ua rau lawv tsis tseem ceeb hauv cov txheej txheem tswj xyuas zoo.
Xaus lus, qhov tseeb thiab kev ntseeg tau ntawm cov ntsuas granite ua rau lawv yog cov cuab yeej tseem ceeb rau txhua tus neeg uas saib qhov tseeb hauv lawv txoj haujlwm. Txawm hais tias nyob rau hauv qhov chaw ua haujlwm lossis hauv tsev ua haujlwm, kev nqis peev rau hauv cov ntsuas granite tuaj yeem txhim kho qhov zoo ntawm kev ntsuas thiab tag nrho cov txiaj ntsig ntawm qhov project.
