Ekusetshenzisweni kokulinganisa ngokunemba okubandakanya amapuleti obuso be-granite, izingxenye zomshini, kanye nezinsimbi zokulinganisa, izici eziningana zobuchwepheshe zingathonya kakhulu imiphumela yokulinganisa. Ukuqonda lezi ziguquguquko kubalulekile ekugcineni ukunemba okungavamile okwaziwa ngakho imishini yokukala esekwe ku-granite.
Isici esiyinhloko esithinta ukuthembeka kokulinganisa sivela ekungaqiniseki okungokwemvelo kwezinsimbi zokuhlola ngokwazo. Amadivayisi anemba kakhulu njengamazinga kagesi, ama-laser interferometer, ama-micrometer edijithali, kanye nama-caliper athuthukile wonke aphethe ukubekezelelana okuchazwe ngumkhiqizi okufaka isandla kwisabelomali sokungaqiniseki sokulinganisa sonke. Ngisho nemishini yezinga eliphezulu idinga ukulinganiswa njalo ngokumelene nezindinganiso eziqashelwayo ukuze kugcinwe amazinga acacisiwe okunemba.
Izimo zemvelo ziveza okunye okubalulekile. I-coefficient yokwanda kokushisa ephansi kakhulu ye-Granite (ngokuvamile i-5-6 μm/m·°C) ayisusi isidingo sokulawula izinga lokushisa. Izindawo zokusebenzela ezine-gradient yokushisa edlula i-±1°C zingabangela ukuphambuka okulinganiselwe kokubili ebusweni be-granite kanye ne-workpiece elinganiswayo. Imikhuba emihle yemboni incoma ukugcina indawo yokulinganisa engu-20°C ±0.5°C eqinile nesikhathi esifanele sokulinganisa zonke izingxenye.
Ukulawulwa kokungcola kumelela isici esivame ukunganakwa. Izinto ezincane ezinqwabelana ezindaweni zokulinganisa zingadala amaphutha atholakalayo, ikakhulukazi uma kusetshenziswa izindlela zokulinganisa eziqondile noma ezihlanganisiwe. Indawo yokuhlanza yekilasi 100 ilungele ukulinganisa okubaluleke kakhulu, yize izimo ze-workshop ezilawulwayo ezinezinqubo zokuhlanza ezifanele zinganele ukusetshenziswa okuningi.
Indlela yokusebenza iveza olunye ungqimba lokwehluka okungenzeka. Ukusetshenziswa kwamandla okulinganisa okuhambisanayo, ukukhethwa kweprobe okufanele, kanye nezindlela zokubeka ezijwayelekile kumele zigcinwe ngokuqinile. Lokhu kubaluleke kakhulu lapho kulinganiswa izingxenye ezingezona ezijwayelekile ezingadinga ukulungiswa okwenziwe ngokwezifiso noma izindlela zokulinganisa ezikhethekile.
Ukuqaliswa kwezinqubo eziphelele zekhwalithi kunganciphisa lezi zinselele:
- Ukulinganiswa kwemishini okuvamile okulandelelwa yi-NIST noma ezinye izindinganiso eziqashelwayo
- Izinhlelo zokuqapha ukushisa ezinesinxephezelo sesikhathi sangempela
- Izinqubo zokulungisa ubuso obusezingeni lokuhlanza
- Izinhlelo zokuqinisekisa opharetha ezinezimfuneko zesikhathi esithile
- Ukuhlaziywa kokungaqiniseki kokulinganisa kwezicelo ezibalulekile
Ithimba lethu lobuchwepheshe linikeza:
• Izinsizakalo zokuhlola izingxenye ze-granite ezihambisana ne-ISO 8512-2
• Ukuthuthukiswa kwenqubo yokulinganisa ngokwezifiso
• Ukwelulekwa ngokulawulwa kwemvelo
• Izinhlelo zokuqeqesha opharetha
Ngemisebenzi edinga amazinga aphezulu okuqiniseka kokulinganisa, sincoma:
✓ Ukuqinisekiswa kwansuku zonke kwezindawo zokubhekisela eziyinhloko
✓ Ukulinganiswa kokushisa okuphindwe kathathu kwezinsimbi ezibalulekile
✓ Ukuqoqwa kwedatha okuzenzakalelayo ukuze kuncishiswe ithonya lomqhubi
✓ Izifundo zokuhlobana ngezikhathi ezithile phakathi kwezinhlelo zokulinganisa
Le ndlela yobuchwepheshe iqinisekisa ukuthi izinhlelo zakho zokulinganisa ezisekelwe ku-granite ziletha imiphumela ehambisanayo nethembekile ehlangabezana namazinga omhlaba wonke okukhiqiza ngokunemba kanye nezinhlelo zokusebenza zokulawula ikhwalithi. Xhumana nochwepheshe bethu be-metrology ukuze uthole izixazululo ezenzelwe wena ezinseleleni zakho zokulinganisa ezithile.
