Hlaziya Ngokuphelele Ukuqinisekiswa Kwe-Metrological kwe-CMM
I-CMM uhlelo lokulinganisa oluyinkimbinkimbi oluhlanganisa ubuchwepheshe bokubona, bokukhanda, bukagesi, bekhompyutha kanye nobokulawula, ngakho-ke kunezici eziningi ezingaqinisekile ezithinta imiphumela yokulinganisa, kodwa kumathuluzi omshini amancane naphakathi nendawo, ukuphambuka kwezinga lokushisa elizungezile kusukela ekushiseni okujwayelekile (20℃) kuyisici esiyinhloko esithinta ukungaqiniseki kokulinganisa. Ukuze kwenziwe imiphumela enembile yokulinganisa i-CMM, izinga lokushisa elizungezile kufanele lilawulwe ngokuqinile ngaphakathi kobubanzi bencazelo ye-CMM.
1. Ingabe uhlelo lokuthola lwe- Umshini Wokuxhumanisa kuthinta imiphumela yokulinganisa?
Siyazi ukuthi uma umshini wokuhlanganisa ulinganisa, I-Probe ithumela isignali ngemva kokuxhumana nomsebenzi ozolinganiswa, bese kuba indawo yokuxhumanisa yeprobe eqoqwa uhlelo lokulawula kanye nekhompyutha, bese kubalwa okudingekayo ukuze kutholakale imiphumela yokulinganisa esiyidingayo. Njengamanje, iningi lama-probe anama-coordinate amathathu uhlobo lokushintsha, olunesimiso sokuklama esiholela ezindaweni ezahlukene zokuthintana zokushintsha ezindaweni ezahlukene, okuletha amaphutha okuthola. Iphutha lithinta ngqo ukungaqiniseki kwemiphumela yokulinganisa yokuhlanganisa. Ngakho-ke ufuna iphutha libe lincane ngangokunokwenzeka.
2. Yimaphi amaphutha angu-21 ezixhumanisi ezintathu?
Kunezingqimba ezintathu zokunyakaza, ngayinye inephutha elilodwa lokuma kanye namaphutha amahlanu ejiyometri. Amaphutha ejiyometri afaka amaphutha okuqondile ngezindlela ezimbili kanye namaphutha e-angular ngezindlela ezimbili. Kunamaphutha ayi-18 ezingqimbeni ezintathu, kanye namaphutha angama-21 ekuqondeni phakathi kwezingqimba ezintathu.
3. Kunini lapho kudingeka khona ukulinganisa amaphutha angu-21?
Isisekelo, ukunemba kanye nokulinganiswa kwezixhumanisi ezintathu kuyinkimbinkimbi. Nakuba kungabhalwanga ohlwini lwemininingwane, iphutha lokulinganisa elingu-21 liyadingeka ezimweni ezilandelayo: ukwamukelwa kabusha; Iphutha lokulinganisa ubude Iphutha lomphumela wokulinganisa; Ama-coordinates ngemva kokunyakaza komshini; Umshini wokuhlanganisa ulungisiwe.
4. Yimiphi imishini edingekayo ukuze kulinganiswe izixhumanisi?
Izindinganiso ezidingekayo ukuze kulinganiswe ama-coordinates amathathu yilezi: usayizi webanga elihambisanayo lebhulokhi yokulinganisa lingu-1000mm; i-interferometer ye-laser. Izinga le-elekthronikhi; Irula yesikwele; Ibhola elijwayelekile, njll.
