Njengesinye sezixhobo zokulinganisa ezisetyenziswa ngokuqhelekileyo kwishishini lemveliso, i-CMM yebhulorho (i-Coordinate Measuring Machine) ibonelela ngokuchaneka okuphezulu kunye nokuchaneka ekulinganiseni iipropati zejometri zezinto.
Ibhedi yegranite ye-CMM yebhulorho ibaluleke kakhulu ekuchanekeni nasekuzinzeni kwayo.I-granite, into eqinile kwaye izinzileyo, ine-coefficient ephantsi yokwandiswa kwe-thermal, eqinisekisa ukuba ibhuloho ye-CMM isebenza kunye ne-thermal drift kunye nokuchaneka okuphezulu.Ke ngoko, ibhedi yegranite yenye yezinto ezibalulekileyo ezichaphazela ukuchaneka kwe-CMM yebhulorho kunye nokuchaneka.Kubaluleke kakhulu ukuyigcina kwaye uyilungelelanise ngamaxesha athile ukuze uqinisekise idatha yomlinganiselo ethembekileyo.
Ke, ngaba ibhedi yegranite yebhulorho yeCMM kufuneka igcinwe ngamaxesha athile kwaye ilinganiswe?Impendulo nguewe, kwaye nantsi isizathu.
Okokuqala, ngexesha lokusebenza kwebhulorho ye-CMM, ibhedi yegranite inokunxitywa okanye yonakaliswe ngenxa yezinto ezahlukeneyo ezinje ngokungqubana, ukungcangcazela kunye nokuguga.Nawuphi na umonakalo kumandlalo wegranite unokubangela ukuba kubekho utshintsho ekucaba, ukuchaneka, kunye nokwekwere.Nokuba ukutenxa kuncinci kunokukhokelela kwimpazamo yokulinganisa, yonakalise ukuthembeka kunye nomgangatho wedatha yokulinganisa.
Ukugcinwa rhoqo kunye nokulinganisa ibhedi yegranite kuya kuqinisekisa ukuchaneka okuhlala kuhleli kwe-CMM yebhulorho nokuthembeka.Ngokomzekelo, ngokusebenzisa i-laser interferometer ukulinganisa ukuchaneka kunye nokuchaneka kwe-squareness, iinjineli ziyakwazi ukuchonga naluphi na ukuphambuka kwinqanaba elilindelekileyo lokuchaneka.Emva koko, banokuhlengahlengisa indawo yebhedi yegranite kunye nokuqhelaniswa nayo ukuze kugcinwe inzuzo yayo echanekileyo ekusebenzeni ngezinto ezizinzileyo neziqinileyo njengegranite.
Okwesibini, amaziko okuvelisa asebenzisa rhoqo ibhulorho ye-CMM inokuyibeka esichengeni sokusingqongileyo, njengamaqondo obushushu aphezulu, ukufuma, okanye uthuli.Ukutshintsha kwendalo kunokukhokelela kuxinzelelo lwe-thermal okanye lomatshini kwibhedi yegranite, echaphazela ukucaba kwayo kunye nokuthe tye.Ke ngoko, ulungelelwaniso kunye nokugcinwa kwamaxesha ngamaxesha kuya kunceda ukunciphisa impembelelo yobushushu kunye nokutshintsha kokusingqongileyo kwibhedi yegranite.
Okokugqibela, ukulinganisa rhoqo kunye nokugcinwa kwebhedi yegranite nako kunokuphucula ukusebenza kakuhle kunye nemveliso yebhulorho yeCMM.Ibhedi yegranite egcinwe kakuhle iqinisekisa ukuba ukuchaneka kwe-CMM yebhulorho kunye nokuzinza kugcinwa kumanqanaba afanelekileyo.Oku kuthetha iimpazamo ezimbalwa zokulinganisa, imfuneko encinci yokuphinda imilinganiselo, kunye nokusebenza kakuhle.Ukuphuculwa kwemveliso akunciphisi kuphela iindleko zemveliso kodwa kukwahambisa idatha yokulinganisa ngokukhawuleza nangaphezulu.
Ukuqukumbela, ibhedi yegranite ye-CMM yebhulorho idlala indima ebalulekileyo ekuqinisekiseni imilinganiselo echanekileyo nechanekileyo kwimveliso, apho imveliso ekumgangatho ophezulu inyanzelekile.Ukugcinwa kwamaxesha athile kunye nokulinganisa ibhedi yegranite kunokunciphisa imiphumo yokunxiba, umonakalo, kunye neendawo ezibuhlungu, ngoko ke, ukuqinisekisa ukuchaneka kwexesha elide kunye nokuthembeka kwebhulorho ye-CMM.Ngaphezu koko, iibhedi zegranite ezigcinwe kakuhle zinceda ukwandisa imveliso, ukulawulwa komgangatho wenzuzo, kunye nokunciphisa iindleko zemveliso.Ke ngoko, ukulungelelaniswa rhoqo kunye nokugcinwa kwebhedi yegranite ngamanyathelo ayimfuneko ekugcineni ibhulorho yeCMM isebenza ngokugqibeleleyo.
