Ukuhlukaniswa Okuhlukile Kwezindlela Zokulinganisa
Indlela yokulinganisa iwukuthola imiphumela yokulinganisa ngokusekelwe kusimiso sokulinganisa esinikeziwe, indlela yokulinganisa ihlukaniswe ngezigaba ezahlukene, nansi izinkomba ezininganaUmamangezindlela zokulinganisa.
Indlela yokulinganisa eqondile yindlela engathola ngqo inani elilinganisiwe, njengokulinganisa ubude bengxenye ngokusebenzisa i-vernier caliper kanye nokulinganisa ububanzi bomgodi nge-micrometer.
Indlela yokulinganisa engaqondile kuyindlela yokuthola inani elilinganisiwe ngokulinganisa amanye amanani anobudlelwano bomsebenzi. Isibonelo, umshini wokulinganisa ohlanganisayo, umshini wokulinganisa obonakalayokanye ne-laser Umshini Wokulinganisa zonke ziyizindlela zokulinganisa ezingaqondile.
Indlela yokulinganisa ukuxhumana kuyindlela yokulinganisa lapho inzwa yemishini yokulinganisa ithinta khona ubuso bengxenye. Izindlela ezivamile zokulinganisa ukuthintana zifaka: i-vernier caliper, i-micrometer, i-styli yokulinganisa kanye nomshini wokulinganisa ingalo ehlangene, njll. Ukulinganisa ukuthintana kuvamile kakhulu ezisetshenziswayo zezimboni zamanje. Kubonakaliswa ukuthembeka okuphezulu, ukunemba okuphezulu kanye nokuphindaphindeka okuhle. Kodwa-ke, ububi bokulinganisa ukuthintana ukuthi amandla okulinganisa ukuthintana angabangela ukuguguleka kwethuluzi lokulinganisa kanye nobuso bengxenye (njengobuso obuthambile), okungathinta ukungaqiniseki kokulinganisa.
Ukulinganisa okungathintani kuyindlela yokulinganisa ukuthi inzwa yemishini yokulinganisa ayithinti ubuso bengxenye. Izindlela ezivamile zokulinganisa okungebona othintana nazo zifaka phakathi ukulinganisa okubonakalayo, ukulinganisa nge-laser, i-tool microscopy, njll. Izinzuzo zokulinganisa okungebona othintana nazo ukuthi inzwa yokulinganisa ayithinti ubuso obulinganiswayo, izingxenye ezizolinganiswa ubuso ngeke zibe nomonakalo, zifaneleka kakhulu ezingxenyeni eziyinkimbinkimbi zobuso obugobile kanye nokulinganisa ubuso obuthambile. Ububi bayo ukunemba okungekho phezulu njengokunemba kokulinganisa kokuthintana.
Umshini wokulinganisa umbono uwukulinganisa okuvamile okungeyona eyokuthintana kanye nokulinganisa okungaqondile. Ithuluzi lokulinganisa ividiyo elinezinhlangothi ezimbili elisebenzisa ihadiwe uqobo (i-CCD, i-eyepiece, umugqa wedatha oqondile, ikhadi lokuthola ividiyo) lingathwebula isithombe ngekhebula liye ekhadini lokuthola idatha yekhompyutha, ngemva kokuthwebula isithombe nge- Isofthiwe esikrinini sekhompyutha, kanye nokulinganisa okusheshayo. Ithuluzi lokulinganisa elibonakalayo lingafunda inani lokufuduka kwerula elibonakalayo ngokushesha futhi lithole umphumela ofiselekayo ngokusebenzisa ukusebenza kwemojuli yesofthiwe ngokusekelwe ku-geometry yendawo. Igrafu ikhiqizwa esikrinini ukuze isetshenziswe yi-opharetha ukulawula isithombe, ukuze kuhlukaniswe ngokubonakalayo ukuphambuka okungenzeka komphumela wokulinganisa.
I-CMM iyisibonelo esijwayelekile sokulinganisa kokuxhumana kanye nokulinganisa okungaqondile. Ukulinganisa okunezinhlanganisela ezintathu kuyindlela yokuthola ulwazi lwezinhlanganisela zobuso bengxenye endaweni ethile yokulinganisa, futhi ukwenza ulwazi lwesimo sento lube yidijithali kubizwa nangokuthi "ukusampula". Lawa manani okulinganisa ayimininingwane ehlukene yezindawo ezihlanganisayo, kunokuba yizici ezithile zejiyometri zobukhulu, indawo kanye nolunye ulwazi. Inqubo yokulinganisa icutshungulwa uchungechunge lwamaphuzu okulinganisa, futhi ama-eigenvalue ejiyometri ahambisanayo ayakhishwa ukuze kutholakale imiphumela yokulinganisa edingekayo.
