Isahani y'ubuso bwa granite ikora neza ni kimwe mu bikoresho by'ingenzi mu gupima ibintu mu nganda. Ikora nk'urugero rw'ibipimo - urugero rw'imiterere y'ubutaka - aho ibindi bipimo byose mu iduka bigereranywa. Iyo isahani y'ubuso idakora neza, buri gipimo cyose gikoreshejwe kizakomeza gutera imbere, kikanduza amakuru y'igenzura n'ibyemezo by'inganda.
Ku bikorwa byinshi by’inganda, kugera ku bugari bungana na mikorometero nke ku gice kinini cy’ubuso birakwiye. Ariko ku rwego rwo hejuru - mu gupima ibikoresho bya semiconductor, laboratwari z’igihugu zipima ibipimo, sisitemu zo gupima fotolithography, hamwe n’ubuhanga bwa CMM buhanitse cyane - ubugari bugomba kwemezwa hakurikijwe urwego rwa nanometer. Ikibazo gikurikiraho ni iki: ni gute wapima ikintu ukurikije ubugari bungana n’ibikoresho bisanzwe biboneka kugira ngo ubipime?
Iyi nkuru irasuzuma amahame, uburyo, n'ibikoresho bikoreshwa mu kugenzura no kugera ku bugari bw'urusobe rw'amazi kuva ku rwego rwa mikorometero kugeza kuri nanometero.
Impamvu Ubusa Bufite Agaciro Kurusha Uko Ubitekereza
Ubugari bw'aho plate y'ubuso bugaragara hakurikijwe amakosa ntarengwa yemewe (MPE) mu gace k'akazi, akenshi agaragara muri mikorometero (μm). Icyiciro AA (urwego rwiza rw'ubucuruzi hakurikijwe ibipimo mpuzamahanga byinshi) gisanzwe gisaba ubugari buri muri 1.6 μm ku gice cya 1000 × 630 mm munsi y'ibipimo ngenderwaho bya DIN 876 by'Abadage, cyangwa mu buryo bwihariye hakurikijwe ibipimo ngenderwaho bya ASME B89.3.7 by'Abanyamerika.
Ariko imiterere y'aho ibintu biherereye ni yo yose. Isahani "irambuye" ifite uburebure bwa 3 μm kuva ku mpera kugeza ku mpera irahagije cyane mu igenzura rusange ry'aho ibintu bibera. Isahani imwe ikoreshwa nk'iy'ibanze mu gupima icyiciro cya fotolithography kigamije kumenya neza aho ibintu biherereye muri nanometero 10 ntabwo ikwiriye na gato - ikosa ryayo ryonyine ni rinini inshuro 300 ugereranyije n'ubushobozi bwo kwihanganira aho ibintu biherereye.
Iki cyuho kiri hagati y’ “ibihagije ku bikorwa byinshi” n’ “ibihagije ku bikorwa byinshi” ni yo mpamvu uburyo bwo gupima ari ingenzi, kandi impamvu abakora plaque zo hejuru bose badafite ubushobozi - cyangwa ubunyangamugayo - bwo kugaragaza neza ibicuruzwa byabo ku rwego rwa nanometer.
Ikibazo cy'ingenzi: Gupima ibyo udashobora kugereranya mu buryo butaziguye
Gupima ubugari bw'ubugari kugeza kuri mikorometero biragoye cyane: shyira isahani ku gipimo kizwi kandi kigororotse, usuzume ubuso neza, hanyuma wandike ibinyuranyo. Ariko gupima ubugari bw'ubugari kugeza kuri nanometero bitanga ikibazo cy'ibanze - nta gipimo cy'ubugari bw'ubugari gihagije kugira ngo gikoreshwe nk'igipimo ngenderwaho cyo kugereranya.
Ku gipimo cya nanometero, buri buso — harimo n'ubuso bw'icyitegererezo — bufite ikosa ryabwo bwite. Uburemere buhindura ubuso bunini mu buryo bupimye. Imiterere y'ubushyuhe itera kwaguka k'ubushyuhe ku gice cy'icyuma. Ndetse n'imiyaga y'umwuka n'urusaku rw'amajwi bishobora guteza ingaruka zishobora kumenyekana. Igipimo ubwacyo kigomba kuba gikubiyemo ibi byose.
Abahanga mu bya Metrology bashyizeho uburyo butandukanye bwo gukemura iki kibazo, bwinshi muri bwo bukaba bukubiyemo gutandukanya ikosa ry'igikoresho n'ikosa ry'ikintu hakoreshejwe uburyo bwa mibare binyuze mu gupima ibintu mu buryo bunyuranye cyangwa mu myanya itandukanye.
Uburyo bw'ingenzi bwo gupima n'ibikoresho
Ibikoresho by'ikoranabuhanga byo mu rwego rwo hejuru n'ibipima uburebure ni bimwe mu bikoresho by'ingirakamaro mu kugaragazaisahani yo hejuruUbugari mu bice binini. Ibikoresho nka WYLER Leveltronic series (Ubusuwisi) bigira ubushobozi bwo kubona uburebure bwa 0.001 mm/m cyangwa irenga - bingana no kubona itandukaniro rya mikorometero 1 hejuru ya metero 1. Mu kunyura ku buso mu buryo butunganye mu buryo bw'urusobe rw'amazi (uburyo bwa Union Jack, imiterere y'amazi, cyangwa imiterere yuzuye y'amazi), umuhanga mu by'ikirere ashobora gukora ikarita yuzuye y'ubutaka.
Interferometry ya laser itanga impinduka mu gupima intambwe kugira ngo habeho ubugari ku rwego rwa sub-micrometer na nanometer. Igikoresho nka Renishaw XL-80 laser interferometer gishobora gupima kwimuka kugera kuri nanometer imwe mu ntera ya metero nyinshi. Mu gupima plate y'ubuso, lumiere ya laser iyoborwa kuri plate mu gihe indorerwamo y'urumuri cyangwa indorerwamo igenzura inzira igenzurwa; kunyura mu lumiere yagaragajwe bigaragaza imiterere y'ubuso.
Gupima ubugari bw'ibipimo hakoreshejwe indorerwamo z'urumuri - ikirahure gikozwe neza cyane cyangwa imiterere ya silica ifite amakosa ari munsi ya nanometero 30 - bishobora kugaragaza neza imiterere y'ibice by'ubuso n'indorerwamo ku buso bwa milimetero kare amagana icyarimwe. Interferometero zuzuye zikoreshwa mu bigo by'igihugu by'ibipimo zishobora gupima ubugari bwa mm 600 mu gipimo kimwe.
Utwuma dupima ubushobozi bw'ikirere hamwe n'udupira tw'umwuka dutanga ubundi buryo, dufite ubushobozi bwo gusuzuma ubuso nta gukoraho. Ibi bikunze gukoreshwa hamwe n'udupira twa granite cyangwa ceramic - ubwabyo bikoreshwa nk'imbonerahamwe y'ingendo - bigatuma habaho uburyo bwo gupima imiterere y'ikirere.
Uburyo bwo Gupima Ibyuma Bitatu: Kwisuzuma Ubwiherero
Bumwe mu buryo bukomeye cyane bwo kugera no kugenzura ubugari budafite ishingiro ryisumbuyeho ni uburyo bw'ibice bitatu. Muri ubu buryo, ibice bitatu bifatanye mu buryo bwihariye bwo gusimburana no kugereranya. Imibare y'uburyo ikorwa yemeza ko ikosa iryo ari ryo ryose riri mu gipande kimwe rigaragazwa binyuze mu mikoranire yacyo n'ibindi bibiri - ibice byose hamwe bisobanura urwego rugororotse aho gusobanura urwego urwo ari rwo rwose rwo hanze.
Uburyo bw'ibice bitatu ni bwo shingiro ry'amateka ryo gukora ibice by'ubuso mu buryo bunonosoye kandi buracyafite akamaro na n'ubu. Ishyirwa mu bikorwa ryabwo rigezweho rihuza ubuhanga gakondo bwo gukubita intoki n'ibipimo by'ikoranabuhanga kugira ngo biyobore inzira yo gukosora - abanyabukorikori b'abahanga bashobora "gusoma" ubuso bakurikije uko bukora, hamwe n'urwego rw'ikoranabuhanga rupima ibyo amaboko abona.
Ingaruka ni inzira ihurira: buri ruhererekane rwo gupima, gupima no gukuraho ibikoresho byatoranijwe bituma amasahani yose uko ari atatu yegereza ubugari butunganye. Ikintu kidashoboka si uburyo ahubwo ni ukwihangana, ubuhanga, n'ibikoresho byo gupima biboneka by'abantu bakora akazi.
Uruhare rw'ibidukikije bipima
Ku rwego rwa nanometero, ibidukikije byo gupima biba igice cy'uburyo bwo gupima. Ubushyuhe bugomba kugenzurwa atari ku gipimo gito gusa ahubwo no ku murongo utoroshye - ubusanzwe ± 0.5°C cyangwa irenga - kuko kwaguka k'ubushyuhe bw'isahani ya granite ya metero 1 kuri 0.1°C gusa ari nanometero amagana. Ubushuhe bugira ingaruka ku buso bwa granite ubwabwo no ku buryo umwuka unyuramo imirasire ya laser interferometry. Gutigita kw'inyubako, HVAC, cyangwa imashini zegereye bitera amakosa yo mu mwanya uhinduka, bigahindura ibipimo by'ubugari buhamye.
Iyi ni yo mpamvu laboratwari zikomeye zo gupima - hamwe n'inganda zikora granite zikora neza cyane - zishora imari mu bidukikije bigenzurwa. Icyumba cyubatswe ku buryo bufatika gicungwa n'ubushyuhe n'ubukonje gifite hasi hadakoreshwa ibintu bihindagurika, imiyoboro irinda guhindagurika hirya no hino, hamwe n'ibyuma bicukura hejuru bidakomeye si ikintu cy'akataraboneka - ni itegeko rya tekiniki kugira ngo ugere ku rwego rwo hejuru kandi wemeze ko ufite uburebure bwo hejuru bw'ubugari.
Imiyoboro irwanya guhindagurika (ubusanzwe ifite ubugari bwa mm 500 na mm 2000 z'ubujyakuzimu ikikije icyumba cyo gupimiramo) igabanya ubugari bw'inyubako mu buryo bufatika. Inzu zikozwe muri sima ikomeye cyane kugeza ku bugari bwa mm 1000 cyangwa zirenga zitanga uburemere n'ubukana bukenewe kugira ngo zirwanye imivurungano ihindagurika. Iyi shoramari mu bikorwa remezo rigena mu buryo butaziguye urwego rw'ubugari uruganda rushobora kugeraho kandi rukagenzura neza.
Gukurikirana Gupima: Urusobe rw'Icyizere
Igipimo cy’ubugari bw’ibipimo ni icy’ukuri nk’ibikoresho byakoreshejwe mu kugikora - kandi ibyo bikoresho ni icy’ukuri gusa iyo bigenzuwe neza hakurikijwe ibipimo by’igihugu n’iby’amahanga. Mu gupima neza, uru ruhererekane rw’ibipimo si amahitamo: ni ishingiro ry’icyizere cy’ibipimo.
Igisobanuro cya Système international d'unités (SI) cy'iki gipimo ubu kigerwaho binyuze mu muvuduko w'urumuri n'ibipimo bya laser bigengwa n'ibigo by'igihugu bipima ibipimo (NMIs) - nka NIST muri Leta Zunze Ubumwe za Amerika, PTB mu Budage, NPL mu Bwongereza, na NIM mu Bushinwa. Impamyabushobozi zo gupima ibipimo zitangwa n'ibigo by'intara cyangwa by'igihugu bipima ibipimo zitanga ibimenyetso by'uko igikoresho runaka cyagereranyijwe n'ibipimo byo hejuru bikurikiranwa n'ibyo bikorwa by'ibanze.
Ku ruganda rukora granite ikora neza, kuba ibikoresho byose bipimirwa byapimwe n’ibigo byemewe byo gupima - bifite icyemezo gikurikizwa ku gipimo cy’igihugu - bivuze ko agaciro k’ubugari bwavuzwe ku bicuruzwa byabo atari imibare idafite ishingiro ahubwo ari ibipimo bya SI-followed hamwe n’ibitazwi neza.
Umwanzuro: Gupima Si Ukwemeza Gusa — Ni Ugukora
Gupima ubugari bw'aho plate y'ubuso iherereye kugeza ku buziranenge bwa nanometero si igenzura rya nyuma ry'ubuziranenge gusa. Ni igice cy'ingenzi cy'igikorwa cyo gukora, kiyobora buri ntambwe yo gukosora mu gihe cyo gusimbuza no gutanga ibitekerezo bituma ubuso bugera ku bipimo bisabwa. Nta bushobozi bwo gupima neza, nta bushobozi bwo gukora neza.
Ubushobozi bwo kugera no kwemeza neza ubugari bw’ibice bya granite mu buso bwa nanometero bugaragaza umupaka nyakuri w’ubushobozi - utandukanya umubare muto w’inganda zikora neza cyane ku isi n’izikora ibikoresho byinshi. Bisaba ibikoresho bikwiye, ibikoresho bikwiye, ibidukikije bikwiye, ibikoresho bikwiye, bigenzurwa ku bipimo bishoboka, bikoreshwa n’abantu bafite amahugurwa n’uburambe kugira ngo babikoreshe neza.
Ku bakoresha ibyuma bipima neza - haba muri laboratwari z'igihugu zipima ibipimo, ibigo bikora ibikoresho bya semiconductor, cyangwa ibigo bigezweho bya CMM - gusobanukirwa uburyo ibyuma bipima si ikibazo gikomeye. Bigena neza niba ibipimo bikorerwa kuri ibyo bikoresho bishobora kwizerwa.
