Malunga nenkqubo ye-injini yeemoto, umngxuma oyile oblique kunye nomngxuma wesikhokelo sevalvu isetyenziswa rhoqo isakhiwo. Ngokubanzi olu hlobo lwesakhiwo lune-engile enesiseko sokucubungula. Ukuchaneka kwabo ngomatshini kuphezulu kakhulu, kudlala indima ebaluleke kakhulu ekusetyenzweni kweenjini. Nangona kunjalo, indlela yokulinganisa ngokuchanekileyo ixabiso lokwenyani lokusetyenzwa kwamalungu, kube yingxaki engxamisekileyo ekufuneka isonjululwe.
Uphuhliso olukhawulezayo lwetekhnoloji yokulinganisa yanamhlanje, ukulungelelanisa umatshini wokulinganisa ngoku bayakwazi ukwenza imilinganiselo ezenzekelayo ngobukrelekrele. Kwimingxuma ethambekileyo, sinokusebenzisa iprobe ejikelezayo enokulinganisa ngokulula kulo naliphi na icala. Kodwa ezinye zeCMM zisebenzisa intloko yokulinganisa engakwazi ukujikeleza ngokukhululekileyo, umlinganiselo wokubala i-angle unzima kakhulu. Kodwa ukusebenzisa ithiyori yee-engile ezimacala mabini okujikeleza, kunokuqhubeka nomsebenzi wokubala othile. Ke unokwenza ukusilela komsebenzi weprobe, unokulinganisa i-angle yomngxuma othotyiweyo ngokuchanekileyo njalo njalo.
Izixhobo zokusebenza zibekwe ngokungacwangciswanga kwisithuba sokulinganisa iCMM, kusenokwenzeka ukuba sithambe esithubeni, ekufuneka silinganise, kwakhona kukwenza isixhobo somatshini ojikelezayo wokulinganisa ulungelelwaniso lwenkqubo ngokuhambelana nezahlulo zesakhelo sereferensi, emva koko wakhe umsebenzi. lungelelanisa kwi-workpiece.
Ukuba i-workpiece ilungiswe kakuhle kwi-workbench, inokuba yi-axis ethambekele ezimbini kuphela, kuphela kwinqwelomoya ethambekele omnye komnye. Oko kuthetha ukuba kukho i-axis yoluntu yesakhelo sereferensi elungelelanisiweyo emibini. Sidinga nje ukujikelezisa ii-axes ezimbini ezithe gqolo kwi-axis engaguqukiyo, sizenze zithande ukuhambelana. Ukufunyanwa kwe-two-dimensional kwanele.
Amacandelo ukufumana undoqo kubalo lwemathematika ukumisela isalathiso axis okanye ezimbini axis, ngoko ke inkqubo inxalenye ulungelelwaniso, inkqubo yokwakha kuphela-ezimbini-dimensional ungafumana nkqu axis ukujikeleza kukugcina i-axis kawonke-wonke coefficient ingaguquki.
Xa inxalenye inenkqubo yokulungelelanisa ezimbini, ukuba ubudlelwane phakathi kwenkqubo yokulungelelanisa ezimbini inombono othile, eli xesha linokuba kwi-original esekelwe kwi-3 d ukulungelelaniswa ngokujikeleza kwe-Angle yokulungelelaniswa kwe-dimensional.
