Izinyathelo Zokuqapha Zokukhetha Umshini Wokulinganisa Ohlanganisa Kathathu
1. Ububanzi Bokulinganisa
Lesi yisici esiyinhloko ekukhetheni i-CMM. Uma sihlela ukuthenga i- umshini wokulinganisa ohlanganisayo (i-CMM), kufanele siqale sazi usayizi ozungezile womkhiqizo, bese sikhetha usayizi we-CMM. Isibonelo, lapho sikhetha i-bridge coordinate Umshini Wokulinganisa, intengo yemishini ilingana nobubanzi be-beam, ngakho-ke sidinga kuphela ukuhlangabezana nobubanzi bokulinganisa, singalandeli ububanzi obukhulu obungadingekile. Uma umsebenzi ozolinganiswa uyingxenye nje yomkhiqizo wonke, khona-ke udinga ukukhetha umshini wokulinganisa ohlanganisayo ongabeka futhi wonke umsebenzi etafuleni, ngenkathi ucabangela isisindo somkhiqizo, ungadluli umkhawulo wokuthwala womshini wokulinganisa ohlanganisayo. Uhlelo lwe-probe olukhethiwe luthinta nobubanzi bokulinganisa, njengoba i-probe ithatha inani elithile lesikhala sokulinganisa.
2. Ukukhethwa Kwe-Probe
1) I-Rotary probe: isetshenziselwa kakhulu ukukhiqiza i-CMM
2) I-probe elungisiwe: isetshenziselwa kakhulu imishini yokulinganisa ehlanganisiwe
Akukho phutha lokujikeleza ngesikhathi sokujikeleza. Ngenxa yokuthi i-probe ejikelezayo isebenza ngendlela ehlukile kune-probe emile, kunomehluko ebangeni lokulinganisa lapho ukhetha idivayisi: i-probe ejikelezayo idinga ibanga lokulinganisa elikhulu. Kwinto efanayo yokusebenza, i-probe ejikelezayo izothatha isikhala esithile ngesikhathi senqubo yokujikeleza. Ngokusho kokuhlangenwe nakho kwethu okusebenzayo, ekukhetheni umshini wokulinganisa ohlanganisayo, uma kusetshenziswa i-probe ejikelezayo, kufanele kucatshangelwe ibanga lomshini wokulinganisa ohlanganisayo.
Umshini wokulinganisa we-Coordinate (CMM) uyithuluzi lokulinganisa ukukala usayizi wejiyometri kanye nephutha lesikhundla sesakhiwo somsebenzi. Lapho sikhetha umshini wokulinganisa we-coordinate, singaqhathanisa ukunemba kokulinganisa kwesakhiwo somsebenzi okufanele silinganiswe nokunemba kokulinganisa komshini wokulinganisa. Ukuqhathanisa okunembile akuyona inqubo elula yokuqhathanisa. Ezicacisweni zobuchwepheshe zomshini wokulinganisa, izinhlobo ezimbili zamafomula wokubala okungaqiniseki zobude be-axis eyodwa kanye nokulinganisa isikhala ngokuvamile zinikezwa, futhi ukunemba kokulinganisa okuphindaphindiwe nakho kunikezwa. Lapho kulinganiswa, ukungaqiniseki kokulinganisa kwepharamitha elinganisiwe kunqunyelwe ebangeni elithile. Ekulinganisweni okujwayelekile, amaphuzu amaningi okulinganisa adinga ukulinganiswa. Lapho kulinganiswa ukubekezelelana kokwakheka, inani elikhulu lamaphuzu okulinganisa liyabandakanyeka, okuzobangela amaphutha.
Ngamafuphi, abasebenzisi kufanele bakhethe umshini wokulinganisa ohambisanayo onokunemba okuphezulu kancane (kufaka phakathi ukunemba okuphindaphindiwe). Lokhu akubangelwa nje ubunzima bomsebenzi wokulinganisa, iphutha lephuzu lokulinganisa elethulwe lingase libe likhulu kunalokho obekulindelwe (ngokushintsha ikhanda lokulinganisa noma ukwelula induku yokwelula kuzoletha iphutha elikhulu lokulinganisa), kodwa futhi ngokwanda kwenani lokusetshenziswa, ukunemba komshini wokulinganisa nakho kuzoncipha.
Kusukela esimweni sokusebenza se-probe kuya ekunembileni kwemiphumela yokulinganisa, kukhona ama-probe okuthintana, ama-probe okuskena othintana nawo kanye nama-probe optical angewona othintana nawo. Uma ukhetha i-probe, isivinini sokulinganisa kanye nemvamisa ye-probe yedivayisi kukhethwa ngokuya ngezidingo zokulinganisa.
Isikali se-grating siyisisekelo sokufunda se-CMM, ngakho-ke i-coefficient yayo yokwandisa ukushisa iyadingeka ibe phansi ngangokunokwenzeka ukuqinisekisa ukunemba kokufunda. Manje ukuthuthukiswa kwezinto ezibonakalayo ze-grating ruler kugxile ekunciphiseni i-coefficient yokwandisa ukushisa. Imishini yokulinganisa ihlukaniswe ngesandla (noma yeselula) kanye ne-CNC (ukulawula okuzenzakalelayo). Ekukhetheni, usayizi wento yokuhlola kufanele ulinganiswe kusukela ezicini zosayizi we-batch, izinga lokuzenzakalela, izinga lekhono lomqhubi kanye nokutshalwa kwezimali. Vele, i Umshini Wokulinganisa we-Cnc inokunemba okuphezulu kanye nesivinini sokulinganisa esisheshayo, kodwa isikhathi sokulungiselela ngaphambi kokulinganisa side kakhulu, izidingo zobuchwepheshe ziphakeme kakhulu, kanti utshalomali lwemali lukhulu kakhulu.
