Izindaba Zenkampani

Umshini wokulinganisa oqondile (i-CMM) uyithuluzi lokulinganisa elisebenza kahle kakhulu elasungulwa ngasekupheleni kwawo-1960. Ukuvela kwawo, ngakolunye uhlangothi, kungenxa yezidingo zokuthuthukiswa kokukhiqiza.

Kunezinhlobo ezintathu zezindlela zokulinganisa ekulinganisweni kwamaphuzu okuvamile: ukulinganisa okuqondile, ukulinganisa kohlelo kanye nokulinganisa kokuzifundela.

Umshini Wokulinganisa Ohlanganisiwe (i-CMM) uyithuluzi elisetshenziselwa ukukala ngokunembile i-geometry yento. Ngokwezindlela ezahlukene zokulinganisa, i-CMM ingahlukaniswa ngezigaba ezilandelayo:

Uma i-CMM isebenzisa isakhiwo somshayo ongunxantathu njengomshayo wayo, ingaba nemiphumela emibi elandelayo ekunembeni.

Njengengxenye ebalulekile yesakhiwo somshini, ukwakheka kanye nesimo somshayo kuthinta ngqo ukuzinza kanye nomthamo wokuthwala wesakhiwo. Umshayo ongunxantathu uwumklamo ovamile womshayo oqukethe onxantathu abathathu abaxhumene, abavame ukusetshenziselwa ukusekela nokuthwala imithwalo esindayo. Nakuba izakhiwo zomshayo ongunxantathu zinezinzuzo ngandlela thile, zingase zibe namaphutha athile esakhiwo.

Uhlelo olujwayelekile lokuhlola i-CMM luqukethe izingxenye ezine: i-probe quill yokulinganisa, isandiso se-probe, ukulungiswa noma isandiso se-stylus, kanye ne-stylus.

Enkambisweni yokuhlola umkhiqizo, uma kutholakala ukuthi idatha yokuhlola yohlelo olufanayo noma ingxenye efanayo ngesikhathi sokuhlolwa okuningi ihluke kakhulu, umphumela awuhambisani, noma uhlukile esimweni sangempela sokuhlanganiswa, kudingeka ihlolwe futhi ihlaziywe kusukela ezicini eziningana. Nanka amaphuzu ayinhloko.

Embonini yokukhiqiza yanamuhla, i-CMM isetshenziswa kakhulu enqubweni yokukhiqiza, okwenza umgomo kanye nesihluthulelo sekhwalithi yomkhiqizo kushintshe kancane kancane kusukela ekuhlolweni kokugcina kuya ekulawulweni kwenqubo yokukhiqiza.

Uma usebenzisa umshini wokulinganisa ohlanganisayo ukuze ulinganise, uma ukuphambuka kokulinganisa kukhulu kakhulu, sicela ulandele indlela elandelayo ukuze uxazulule inkinga.

Inqubo yokusebenza ye-CMM ngokuvamile ihlanganisa ukulungiselela, uhlelo lokulinganisa olukhethiwe, ukusetha amapharamitha okulinganisa, ukucubungula idatha, ukucubungula idatha, ukucubungula okulandelayo.

Kunezinhlobo eziningi zama-probe e-CMM, ahlukaniswe kakhulu ngokuthi ukujikeleza okuhleliwe, ukujikeleza ngesandla, ukukhomba okuzenzakalelayo kokujikeleza ngesandla, ukukhomba okuzenzakalelayo kokujikeleza kanye nohlelo lokuthola olujwayelekile.

I-CMM igxile ekulinganisweni kwejometri esikhaleni esinezinhlangothi ezintathu, kuyilapho ama-profilometer egxile kuphrofayili yobuso kanye nokungaguquguquki. I-CMM ifanelekela ukusetshenziswa okubanzi kwezimboni, kuyilapho ama-profilometer egxile kakhulu ekuhlaziyweni kwezimpawu zobuso.
