Oomatshini bokulinganisa abathathu (ii-CMMs) zizixhobo ezisetyenziswa ngokubanzi kuluhlu lwamashishini okuvelisa ukulinganisa ubungakanani obuchanekileyo, ijometri, kunye nendawo yezakhiwo ze-3D ezinzima.Ukuchaneka kunye nokuthembeka kwaba matshini kubaluleke kakhulu ekuqinisekiseni umgangatho wemveliso yokugqibela, kwaye enye into ephambili eyenza igalelo ekusebenzeni kwabo yinto ephambili ephantsi kwenkqubo yokulinganisa: i-granite surface plate.
IGranite yaziwa ngeempawu zayo ezikhethekileyo zomzimba, kubandakanya ukuqina kwayo okuphezulu, i-coefficient ephantsi yokwandiswa kwe-thermal, kunye nomthamo ogqwesileyo wokudambisa.Ezi mpawu zenza ukuba ibe yinto efanelekileyo kwi-CMM, efuna isiseko esizinzile nesiqinileyo ukuxhasa iiprobes zabo zokulinganisa kunye nokubonelela ngedatha echanekileyo kunye neyongaguqukiyo.Kweli nqaku, siza kuphonononga iingenelo zegranite njengeyona nto iphambili kwiiCMM kunye nokuba inegalelo njani ekusebenzeni kwazo.
1. Ukuqina: I-Granite inemodyuli ephezulu kakhulu ye-Young's, oku kuthetha ukuba ixhathisa kakhulu kwi-deformation xa iphantsi koxinzelelo lomatshini.Olu lukhuni luqinisekisa ukuba i-granite surface plate ihlala ihleli kwaye izinzile phantsi kobunzima besampuli okanye iprobe yokulinganisa, ukuthintela nakuphi na ukuphambuka okungafunekiyo okunokuphazamisa ukuchaneka kwemilinganiselo.Ukuqina okuphezulu kwegranite kukwavumela ii-CMM ukuba zakhiwe ngeepleyiti ezinkulu zegranite zomhlaba, ezithi nazo zibonelele ngesithuba esikhulu seendawo ezinkulu kunye neejometri ezintsonkothileyo.
2. Ukuzinza kwe-Thermal: I-Granite ine-coefficient ephantsi kakhulu yokwandiswa kwe-thermal, oku kuthetha ukuba ayinwebeki okanye iyancipha kakhulu xa ibonakaliswe utshintsho kwiqondo lokushisa.Le propati iyimfuneko kwii-CMM kuba naluphi na utshintsho kubungakanani bepleyiti yomphezulu ngenxa yotshintsho lobushushu luya kuvelisa iimpazamo kwimilinganiselo.Iipleyiti zomphezulu weGranite zinokubonelela ngemilinganiselo ezinzileyo nethembekileyo nakwiindawo apho ukuguquka kwamaqondo obushushu kubaluleke kakhulu, njengefektri okanye iilebhu.
3. Umthamo wokudambisa: Igranite inesakhono esisodwa sokufunxa ii-vibrations kwaye ibathintele ekubeni bachaphazele imilinganiselo.Ukungcangcazela kunokuvela kwimithombo eyahlukeneyo efana nokothuka koomatshini, oomatshini abasebenzayo, okanye izinto ezenziwa ngabantu kufutshane neCMM.Umthamo wokudambisa wegraniti unceda ukunciphisa impembelelo yokungcangcazela nokuqinisekisa ukuba ayenzi ngxolo okanye iimpazamo zomlinganiselo.Lo mhlaba ubaluleke kakhulu xa usebenza ngeendawo ezibuthathaka kakhulu okanye ezibuthathaka okanye xa ulinganisa kumanqanaba aphezulu achanekileyo.
4. Ukuqina: I-Granite yinto enzima kakhulu kwaye inokunyamezela ukusetyenziswa kwexesha elide kunye nokuxhatshazwa kwiindawo zoshishino.Iyakwazi ukumelana nemikrwelo, i-corrosion, kunye nokugqoka kunye nokukrazula, okwenza kube lukhetho olufanelekileyo lwecandelo ekufuneka linike imilinganiselo ezinzileyo nechanekileyo kwixesha elide.Iiplati zegranite zomhlaba zifuna ukugcinwa okuncinci kwaye zingahlala amashumi eminyaka, ukubonelela ngokutyalomali kwexesha elide kwi-CMM.
5. Ukucoca ngokulula: I-Granite ilula kakhulu ukuyicoca kunye nokugcina, okwenza kube yinto ekhethekileyo yokusetyenziswa kwezoshishino.Indawo yayo engabonakaliyo ichasene nomswakama kunye nokukhula kwebhaktheriya, ukunciphisa umngcipheko wokungcola kunye nokuqinisekisa ukunyaniseka kwemilinganiselo.Iipleyiti zomphezulu we-Granite zinokucocwa ngokukhawuleza ngamanzi kunye nesepha kwaye zifuna umgudu omncinci wokuzigcina zikwimeko entle.
Ukuqukumbela, i-granite njengenxalenye ephambili yee-CMM ibonelela ngeenzuzo ezibalulekileyo ezinegalelo ekusebenzeni kwazo kunye nokuthembeka.Ukuqina, ukuzinza kwe-thermal, umthamo wokudambisa, ukuqina, kunye nokulula kokucoca kwenza i-granite ibe yinto efanelekileyo yokukhethwa kwecandelo elimele linike imilinganiselo echanekileyo kunye neyokuhambelanayo phantsi kweemeko ezahlukeneyo.Ii-CMM ezakhiwe ngeepleyiti zomphezulu wegranite zomelele ngakumbi, zizinzile, kwaye zichaneke ngakumbi, zibonelela ngokuzithemba kunye nokuchaneka okufunekayo ukwenza iimveliso ezikumgangatho ophezulu.
