A bridge coordinate measuring machine (CMM) ke letsete la bohlokoa bakeng sa indasteri leha e le efe ea tlhahiso kaha e thusa ho netefatsa hore lihlahisoa tse hlahisoang li finyella litlhoko le litekanyetso tse hlokahalang.Ha u khetha CMM ea borokho, lintlha tse fapaneng li hloka ho nahanoa, 'me e' ngoe ea lintlha tsa bohlokoa ka ho fetisisa ke mofuta oa thepa ea bethe e lokelang ho sebelisoa.Bethe ea granite ke khetho e ratoang bakeng sa li-CMM tse ngata tsa borokho, 'me sehlooho sena se tla tšohla hore na ke hobane'ng ha libethe tsa granite li le bohlokoa tabeng ea khetho.
Granite ke mofuta oa lejoe le chesehang le entsoeng ho tloha ho khanya e liehang ea magma ka tlas'a lefatše.Lejoe lena le tsebahala ka ho tšoarella ha lona, ho thatafala, le ho hanyetsa ho senya le ho taboha, ho etsa hore e be thepa e loketseng bakeng sa kaho ea libethe tsa CMM.Granite e na le botsitso bo botle ba sebopeho, ho bolelang hore e khona ho boloka sebopeho le boholo ba eona leha e le tlas'a liphetoho tsa mocheso le mongobo.Ho feta moo, granite e na le coefficient e tlase ea katoloso ea mocheso, e etsang hore e be thepa e ntle haholo ea ho fokotsa kholo ea mocheso nakong ea tekanyo.
Lebaka le leng le etsang hore libethe tsa granite li tumme ho li-CMM tsa borokho ke ka lebaka la matla a tsona a phahameng a mongobo.Damping e bolela bokhoni ba thepa ea ho monya ho thothomela le ho fokotsa lerata.Bokhoni bo phahameng ba granite bo thusa ho fokotsa ho thothomela le lerata le hlahisoang nakong ea ho lekanya, ka hona ho ntlafatsa ho nepahala ha tekanyo le ho pheta-pheta.Ho phaella moo, granite e na le conductivity e tlaase ea motlakase, e thusang ho fokotsa kotsi ea ho kena-kenana le motlakase nakong ea ho lekanya, ho eketsa botšepehi ba tekanyo ea mochine.
Granite e sebelisoang ha ho hahoa li-CMM tsa borokho hangata ke tsa boleng bo phahameng, tse thusang ho ntlafatsa ho nepahala le nako e telele ea tsamaiso.Lebaka ke hobane granite ea chekoa, ea bentšoa, 'me e felile ho latela maemo a khethehileng ho netefatsa hore e na le sebaka se bataletseng le se ts'oanang.Ho bata ha bethe ea granite ke ntlha ea bohlokoa hobane e fana ka sebaka se tsitsitseng sa litšupiso moo probe e tsamaeang teng nakong ea tekanyo.Ho phaella moo, ho tšoana ha bethe ea granite ho tiisa hore ho na le ho senyeha ho fokolang kapa ho sotha sebakeng sa ho lekanya, ho lebisang ho litekanyo tse nepahetseng le tse ka phetoang.
Ka kakaretso, ho khetha borokho ba CMM bo nang le bethe ea granite ke taba ea bohlokoa ka lebaka la melemo e mengata eo e fanang ka eona.Bethe ea granite e fana ka botsitso bo phahameng ba boemo bo holimo, coefficient e tlase ea katoloso ea mocheso, matla a ho futhumatsa a phahameng, conductivity e tlase ea motlakase, le pheletso ea boleng bo holimo.Lintlha tsena kaofela li kenya letsoho ho nepahala, ho pheta-pheta, le ho phela halelele ha tsamaiso.Ka hona, ha u khetha CMM ea borokho, etsa bonnete ba hore bethe ea granite e finyella litekanyetso le litlhaloso tse hlokahalang ho finyella liphello tse nepahetseng tsa tekanyo.
