Kuzinhlelo zokusebenza zokulinganisa ukunemba ezihlanganisa amapuleti angaphezulu kwegwadle, izingxenye zomshini, namathuluzi okulinganisa, izici ezimbalwa zobuchwepheshe zingathonya kakhulu imiphumela yokulinganisa. Ukuqonda lokhu okuguquguqukayo kubalulekile ukuze kugcinwe ukunemba okukhethekile lokho okokusebenza kwe-metrology okusekelwe kugwadule eyaziwa ngakho.
Into eyinhloko enomthelela ekuthembekeni kokulinganisa isukela ekungaqinisekini okungokwemvelo kwamathuluzi okuhlola ngokwawo. Amadivayisi anemba okuphezulu njengamaleveli e-elekthronikhi, ama-laser interferometers, ama-micrometer edijithali, nama-caliper athuthukisiwe wonke aphethe ukubekezelela okucaciswe ngumkhiqizi okunikela kuso sonke isabelomali sokungaqiniseki kokulinganisa. Ngisho nemishini yezinga eliphezulu idinga ukulinganiswa okuvamile ngokumelene namazinga aziwayo ukuze kugcinwe amazinga okunemba athile.
Izimo zemvelo zinikeza okunye ukucatshangelwa okukhulu. I-granite ye-thermal expansion coefficient ephansi uma kuqhathaniswa (imvamisa engu-5-6 μm/m·°C) ayisusi isidingo sokulawula izinga lokushisa. Indawo yokusebenzela enamagradient ashisayo angaphezu kuka-±1°C angabangela ukuhlanekezela okulinganisekayo kukho kokubili indawo yereferensi yegwadle kanye nendawo yokusebenza elinganiswayo. Imikhuba engcono kakhulu yemboni incoma ukugcina indawo yokulinganisa engu-20°C ±0.5°C ezinzile ngesikhathi sokulinganisa esifanelekile sazo zonke izingxenye.
Ukulawula ukungcola kumelela into evame ukubukelwa phansi. I-sub-micron particulate matter enqwabelana endaweni yokulinganisa ingadala amaphutha abonakalayo, ikakhulukazi uma kusetshenziswa izindlela zokulinganisa eziyisicaba noma ze-interferometric. Indawo yegumbi lokuhlanza le-Class 100 ilungele izilinganiso ezibaluleke kakhulu, nakuba izimo zeshabhu elawulwayo ezinezimiso ezifanele zokuhlanza zinganela izinhlelo zokusebenza eziningi.
Isu lomsebenzisi lethula esinye isendlalelo sokuhlukahluka okungaba khona. Ukusetshenziswa kwamandla okulinganisa okungaguquki, ukukhetha okufanele kwe-probe, kanye nezindlela zokuma ezijwayelekile kufanele kugcinwe ngokucophelela. Lokhu kubaluleke kakhulu uma ukala izingxenye ezingajwayelekile ezingase zidinge ukulungiswa ngendlela oyifisayo noma izindlela zokulinganisa ezikhethekile.
Ukusebenzisa amaphrothokholi ekhwalithi aphelele kunganciphisa lezi zinselele:
- Ukulinganisa okokusebenza okujwayelekile kulandelelwa ku-NIST noma amanye amazinga aziwayo
- Amasistimu okuqapha okushisayo anesinxephezelo sesikhathi sangempela
- Izinqubo zokulungiswa kwendawo esezingeni elihlanzekile
- Izinhlelo zokunikeza izitifiketi ezisebenza ngezikhathi ezithile
- Ukuhlaziywa kokungaqiniseki kokulinganisa kwezinhlelo zokusebenza ezibucayi
Ithimba lethu lobuchwepheshe lihlinzeka:
• Amasevisi okuhlola ingxenye ye-Granite athobela i-ISO 8512-2
• Ukuthuthukiswa kwenqubo yokukala ngokwezifiso
• Ukubonisana nokulawulwa kwemvelo
• Izinhlelo zokuqeqesha opharetha
Ngemisebenzi edinga amaleveli aphezulu okuqinisekisa ukulinganisa, sincoma:
✓ Ukuqinisekiswa kwansuku zonke kwezindawo eziyinkomba eziyinhloko
✓ Ukulinganisa izinga lokushisa kathathu kwamathuluzi abalulekile
✓ Ukuqoqwa kwedatha okuzenzakalelayo ukunciphisa ithonya lika-opharetha
✓ Izifundo zokuhlobana ngezikhathi ezithile phakathi kwezinhlelo zokulinganisa
Le ndlela yobuchwepheshe iqinisekisa amasistimu akho okulinganisa asuselwa kugwadle alethela imiphumela engaguquki, enokwethenjelwa ehlangabezana namazinga omhlaba wokukhiqiza ngokunemba kanye nezinhlelo zokusebenza zokulawula ikhwalithi. Xhumana nochwepheshe bethu be-metrology ukuze uthole izisombululo ezenziwe ngokwezifiso ezinseleleni zakho zokulinganisa ezithile.
