Izixhobo zokulinganisa zemveli kunye noomatshini bokulinganisa abalungelelanisiweyo (CMM) zombini zisetyenziselwa ukulinganisa ubukhulu, kodwa kukho umahluko omkhulu kubuchwepheshe, ukuchaneka kunye nokusetyenziswa. Ukuqonda la mahluko kubalulekile ekukhetheni indlela efanelekileyo yokulinganisa kwiimfuno ezithile zokuvelisa.
Izixhobo zokulinganisa zemveli, ezinje ngee-calipers, ii-micrometer, ii-height gauges, njl.njl., zizixhobo eziphathwa ngesandla ezixhomekeke ekusebenzeni ngesandla. Zifanelekile kwiimilinganiselo ezilula kwaye zihlala zisetyenziswa kwiindawo zokuvelisa ezincinci. Ngokwahlukileyo koko, umatshini wokulinganisa odibeneyo yinkqubo entsonkothileyo elawulwa yikhompyutha esebenzisa ii-probes ukulinganisa iipropati zomzimba zento ngokuchanekileyo okuphezulu. Amandla e-CMM okubamba inani elikhulu lamanqaku edatha ayenza ifaneleke kwiijiyometri ezintsonkothileyo kunye nokulinganisa okuchanekileyo okuphezulu.
Omnye womahluko ophambili phakathi kwezixhobo zokulinganisa zemveli kunye noomatshini bokulinganisa abalungelelanisiweyo linqanaba lokuchaneka. Izixhobo zemveli zinemida ngokubhekiselele ekuchanekeni, zihlala zibonelela ngokuchaneka ngaphakathi kwee-microns ezimbalwa. Kwelinye icala, ii-CMM zinokufikelela ekuchanekeni kwe-sub-micron, zizenze zifaneleke kumashishini afuna ukunyamezelana okungqongqo kakhulu, njengokwenziwa kweenqwelo moya kunye neemoto.
Omnye umahluko ophambili sisantya nokusebenza kakuhle kokulinganisa. Izixhobo zemveli zifuna ukusebenza ngesandla kwaye zihlala zicotha xa zithelekiswa neeCMM, ezinokuskena ngokuzenzekelayo kwaye zilinganise amanqaku amaninzi kwindawo yokusebenza ngexesha elifutshane. Oku kwenza iiCMM zisebenze ngakumbi kwimveliso enkulu kunye neendawo ezintsonkothileyo.
Ukongeza, ukuguquguquka kokulinganisa ngumahluko ophawulekayo phakathi kwezixhobo zemveli kunye neeCMM. Nangona izixhobo zemveli zilinganiselwe kumlinganiselo othe ngqo kunye nejometri ezilula, iiCMM zinokulinganisa iimilo ezintsonkothileyo ze-3D kunye neekhonto, nto leyo ezenza zifaneleke ukuhlola iindawo ezintsonkothileyo nokwenza uhlolo olupheleleyo lolawulo lomgangatho.
Ngamafutshane, izixhobo zokulinganisa zemveli zifanelekile kwiimilinganiselo ezisisiseko kunye nemisebenzi emincinci, ngelixa ii-CMM zibonelela ngezakhono eziphambili ngokubhekiselele ekuchanekeni, isantya kunye nokuguquguquka. Ukuqonda umahluko phakathi kwezi ndlela zimbini zokulinganisa kubalulekile ekukhetheni isisombululo esifanelekileyo ukuhlangabezana neemfuno ezithile zokuvelisa.
