Yiziphi izindinganiso zokugreda zenkundla yokuhlola igwadle yebanga elingu-00?

Inkundla yokuhlola igwadle yebanga elingu-00 iyithuluzi lokulinganisa elinembe kakhulu, futhi amazinga ayo okugreda ahlanganisa ngokuyinhloko izici ezilandelayo:

Ukunemba Kwejiyomethri:

Ukucaba: Iphutha lokucaba kuyo yonke indawo yesikhulumi kufanele libe lincane kakhulu, livamise ukulawulwa kuye ezingeni le-micron. Isibonelo, ngaphansi kwezimo ezijwayelekile, ukuchezuka kobucaba akumele kudlule ama-microns angu-0.5, okusho ukuthi indawo yesikhulumi cishe isicaba ngokuphelele, ihlinzeka ngereferensi ezinzile yokulinganisa.

Ukufana: Kudingeka ukufana okuphezulu kakhulu phakathi kwezindawo zokusebenza ezihlukene ukuze kuqinisekiswe ukunemba kokulinganisa. Isibonelo, iphutha lokufana phakathi kwezindawo zokusebenza ezimbili ezincikene kufanele libe ngaphansi kwama-microns angu-0.3 ukuze kuqinisekiswe ukwethembeka kwedatha lapho kulinganiswa ama-engeli noma izindawo ezihlobene.

I-Perpendicularity: I-perpendicularity phakathi kwendawo ngayinye yokusebenza nendawo eyinkomba kufanele ilawulwe ngokuqinile. Ngokuvamile, ukuchezuka kwe-perpendicularity kufanele kube phakathi kwama-microns angu-0.2, okubalulekile ezinhlelweni zokusebenza ezidinga ukukalwa okuqondile, njengesikali sokuhlanganisa esinezinhlangothi ezintathu.

Izinto ezibonakalayo:

I-Granite: I-Granite enokwakheka okufanayo kanye nesakhiwo esiminyene ngokuvamile sisetshenziswa njengesisekelo. Ukuqina kwayo okuphezulu, ukumelana nokugqokwa okuhle kakhulu, kanye ne-coefficient ephansi yokwandisa ukushisa okushisayo kuqinisekisa ukuzinza kobukhulu beplathifomu kanye nokumelana nokuguquka ngesikhathi sokusetshenziswa kwesikhathi eside. Isibonelo, i-granite ekhethiwe kufanele ibe nobulukhuni be-Rockwell obungu-70 noma ngaphezulu ukuze kuqinisekiswe ukuguga okuhle kakhulu kwenkundla nokumelana nokuklwebheka.

Ukuzinza: Izinkundla zokuhlola igwadle zebanga elingu-00 zithola ukwelashwa okuqinile kokuguga ngesikhathi sokukhiqiza ukuze kuqedwe izingcindezi zangaphakathi, kuqinisekiswe ukusebenza okuzinzile ngaphansi kwezimo zemvelo ezihlukahlukene. Ngemuva kokwelashwa, izinga lokushintsha kobukhulu beplathifomu aleqi ku-0.001 mm/m ngonyaka, lihlangabezana nezimfuneko zokulinganisa ukunemba okuphezulu.

Ikhwalithi Yobuso:

Ubulukhuni: Ubulukhuni bengxenye yesikhulumi buphansi kakhulu, ngokuvamile bungaphansi kuka-Ra0.05, okuholela ekubushelelezini okufana nesibuko. Lokhu kunciphisa ukungqubuzana nephutha phakathi kwethuluzi lokulinganisa nento elinganiswayo, ngaleyo ndlela kuthuthukisa ukunemba kokulinganisa.

Ukucwebezela: Ukucwebezela okuphezulu kwenkundla, ngokuvamile okungaphezu kuka-80, akugcini nje ngokuthuthukisa ubuhle bayo kodwa futhi kusiza ukubhekwa komsebenzisi kwemiphumela yokulinganisa nokulinganisa.

Ukuzinza Kokunemba Kwesilinganiso:

Ukuzinza Kwezinga Lokushisa: Ngenxa yokuthi izilinganiso zivame ukudinga ukusebenza ezindaweni ezihlukene zezinga lokushisa, inkundla yokuhlola igwadle yebanga elingu-00 kufanele ibonise ukuzinza okuhle kakhulu kwezinga lokushisa. Ngokuvamile, ukunemba kokulinganisa kweplathifomu akufanele kuhluke ngaphezu kwama-microns angu-0.1 ebangeni lokushisa elingu--10°C ukuya ku-+30°C, okuqinisekisa imiphumela yokulinganisa enembile ngaphansi kwazo zonke izimo zokushisa.

Ukuzinza Kwesikhathi Eside: Ukunemba kokulinganisa kwenkundla kufanele kuhlale kuzinzile ekusetshenzisweni kwesikhathi eside, futhi ngemva kwesikhathi esithile sokusetshenziswa, ukunemba kwayo akufanele kuhluke ngale kobubanzi obushiwo. Isibonelo, ngaphansi kwezimo ezijwayelekile zokusebenza, ukunemba kokulinganisa kwenkundla akufanele kuchezuke ngama-microns angaphezu kuka-0.2 esikhathini esingangonyaka owodwa.

Kafushane, izindinganiso zokugreda zezingxenyekazi zokuhlola zegwadle zebanga elingu-00 ziqine kakhulu, ezihlanganisa izici eziningi ezihlanganisa ukunemba kwejometri, izakhiwo zezinto ezibonakalayo, ikhwalithi ephezulu, nokuzinza kokunemba kokulinganisa. Kuphela ngokuhlangabezana nalawa mazinga aphezulu lapho inkundla ingadlala indima yayo ebalulekile ekulinganisweni okunembayo okuphezulu, ihlinzeka ngokulinganisa okunembile nokuthembekile kocwaningo lwesayensi, ukuhlolwa kobunjiniyela, nokulawula ikhwalithi.
