Mu isi ihindagurika ry’imashini zikora neza cyane—aho sisitemu zo kubona imashini zitunganya amakuru abarirwa muri za miriyoni ku isegonda na moteri zikora neza zigenda zihuta mu kirere—ikintu cy’ingenzi cyane gikomeza kuba ubuziranenge bwa geometrike butajegajega. Buri mashini iteye imbere, kuva ku bikoresho byo kugenzura wafer kugeza ku byuma binini bya laser, igomba gukurikirana inkomoko yayo kugeza ku murongo n’umuyoboro bishobora kwemezwa. Iki gisabwa cy’ibanze niyo mpamvu ibikoresho byihariye bya metrology, cyane cyane granite straight ruler ifite ubuso bubiri butanga ubuziranenge, amategeko ya granite linear, naamategeko agenga indege ya granite, biracyari amahame y'ingenzi mu nganda zikoresha ikoranabuhanga rihanitse.
Ibi bikoresho si ibice by'amabuye asukuye gusa; ni ishusho nyayo y'ibipimo ngenderwaho by'isi yose, bitanga ishusho idahinduka aho imiterere y'imashini zigezweho isobanurwa, ikemezwa, kandi igasubizwa.
Fiziki y'Ukuri kw'Ubunini
Gukomeza kwishingikiriza kuri granite mu gihe cya nanometer bishingiye cyane kuri fiziki y'ibintu, aho ibikoresho gakondo by'ubuhanga nk'icyuma cyangwa icyuma cyashongeshejwe binanirwa kuzuza ibisabwa kugira ngo bibe bihamye.
Umwanzi w’ingenzi w’ubuziranenge ni uguhindagurika kw’ubushyuhe. Ibyuma bigaragaza ko ubushyuhe bushobora kwaguka cyane (CTE), bivuze ko ihindagurika rito ry’ubushyuhe ritera impinduka zipimirwa ku bunini. Mu buryo bunyuranye, granite yirabura yihariye ifite ubuziranenge buhanitse cyane kandi ifite ubushyuhe bwinshi. Iyi miterere yemerera ibikoresho bya granite gukomera mu gihe ubushyuhe buhindagurika, bigatanga umurongo cyangwa urwego rw’ifatizo rushobora gusobanurwa neza kandi rudahungabanywa n’urusaku rw’ibidukikije.
Uretse ubushyuhe, icyuma gipima amashanyarazi ni ingenzi cyane. Granite ifite ubushobozi bwo gupima imbere mu buryo buhanitse, butuma yinjiza vuba ingufu za mashini no gusibanganya umuyaga. Icuma gipima icyuma, iyo gihungabanye, gikunda gukurura, kigakwirakwiza amakosa muri sisitemu ipimwa. Ariko, icuma gipima icyuma gipima gitambitse vuba, kigenzura ko ibipimo bigaragaza imiterere nyayo y'ikintu kigamije, atari uguhindagura kw'igikoresho ubwacyo. Ibi ni ingenzi cyane cyane iyo ukoresha sisitemu ndende cyangwa uburyo bwo gupima amashanyarazi bufite ubushobozi bwo hejuru.
Gusobanura umurongo: Umutegetsi w'ibara rya Granite ufite ubuso bubiri butunganye
Igisabwa cyane kandi cy’ingenzi mu kubaka imashini ni ukugororoka. Buri nzira y’umuhanda iyobora, sisitemu y’imodoka, n’urwego rwo guhindura ibintu bishingiye ku murongo w’urugendo ugororotse neza. Inyuguti y’icyuma gigororotse cya granite ifite ubuso bubiri butunganye ni yo ikora neza muri ubu buryo, itanga impande zigororotse kandi, by’ingenzi, urwego rw’icyitegererezo rungana.
Kugira ubuso bubiri bugororotse kandi buhanganye bituma agakoresho gakoreshwa atari mu kugenzura gusa ko urumuri rugororotse cyangwa urwego rw'ikoranabuhanga ku nkombe yo hejuru y'akazi, ahubwo no mu gukora igenzura rihambaye ry'uburyo ibintu bingana no kuzunguruka mu birindiro by'imashini. Urugero, mu gushyiraho ibikoresho binini byo guteranya cyangwa inkingi ndende z'imashini, ubwo buso bubiri bungana bwemerera umutekinisiye kwemeza ko inzira ebyiri zitandukanye zo gushyiramo zijyanye kandi zijyanye n'umurongo mukuru w'icyitegererezo (nk'ikibaho cy'ubuso). Ubu buryo bwinshi bworoshya intambwe z'ingenzi zo guhuza, butuma imashini iba yubatswe kare kandi ihuje n'ukuri kuva ku rufatiro kugeza hejuru.
Ubuso bw'izi nyuguti bugomba kuzuza amahame akomeye cyane, akenshi yemewe n'ubushobozi bwo kwihanganira ibintu bupimirwa muri mikoroni cyangwa ibice byazo, bigasaba urwego rw'ubuso bushobora kugerwaho gusa binyuze mu nzira zo gufunga zigenzurwa cyane.
Uburyo bwo gupima ibintu butandukanye: Amategeko agenga umurongo wa granite
Ijambo amategeko agenga umurongo wa granite rikunze gukoreshwa nk'icyiciro rusange cy'ibikoresho byagenewe gutanga icyitegererezo cyemewe cyo kugorora mu ntera nini. Aya mategeko ni ingenzi ku mirimo minini y'inganda, nka:
-
Amakosa yo Gupima: Bikoreshwa hamwe na interferometer za laser cyangwa auto-collimators kugira ngo hamenyekane ikosa ryo kugororoka mu nzira y'urugendo rw'umurongo w'imashini. Imiterere y'itegeko rya granite itanga imiterere ihoraho ikenewe kuri ibi bipimo by'imbaraga cyane.
-
Guhuza ibyuma: Bikora nk'ibikoresho by'agateganyo kandi byemewe kugira ngo ibice binini (nk'imiringa y'ibiraro cyangwa amaboko y'ibiganza) bibe bigororotse neza mbere yo gufungwa burundu.
-
Gupima Ibikoresho byo mu rwego rwo hasi: Gutanga icyerekezo cy’ibanze cy’aho ibikoresho byo mu rwego rwo hasi, imiterere y’imikorere cyangwa ubuyobozi bipimirwa.
Kuba granite iramba kandi ihamye bivuze ko iyo itegeko ry’umurongo wa granite rimaze kwemezwa, ubuziranenge bwayo bugumaho igihe kirekire kurusha ibikoresho by’icyuma bingana, bigabanura inshuro n’igiciro cyo kongera kuyihindura.
Gushyiraho Indege Itunganye: Amategeko Ajyanye n'Indege ya Granite
Amategeko agenga imiterere y’ahantu hakozwe mu buryo bw’umwihariko agamije gukemura ikibazo cy’ishingiro ryemewe rifite isura ebyiri zidasanzwe kandi zigororotse. Mu gihe imiterere igororotse yibanda ku murongo, amategeko ajyanye yibanda ku buryo uburebure n’ubugari bingana mu gice cy’aho bakorera.
Aya mategeko ni ingenzi kuri:
-
Gupima no Gutandukanya: Bikoreshwa nk'ibipimo byo gushyiramo ibice cyangwa ibishyigikizo bihamye aho uburebure bungana n'ubugari hagati y'ingingo ebyiri zihanganye bigomba kuba ntakuka, nko mu gihe cyo gushyiraho ibice by'urumuri cyangwa gupima uburebure.
-
Kugenzura Imbonerahamwe no Gupima Imbonerahamwe: Bikoreshwa ku masahani yo hejuru kugira ngo byemezwe ko ibice bitandukanye by'isahani bigumana uburebure bumwe ugereranije n'ubundi.
-
Gupima neza: Bikoreshwa mu mirimo yo guteranya aho intera nyayo iri hagati y’ibintu bibiri bihwanye igomba kuba ijyanye n’ubushobozi bwo kwihanganira ibintu buciriritse, hashingiwe ku buryo itegeko rihuriza hamwe ibintu bibiri by’ingenzi.
Kugira ngo habeho gukora neza amategeko agenga imiterere y’indege ya granite asaba kugenzura cyane uburyo bwo gusya no gukurura, hakagaragazwa ko impande zombi zitagomba gusa kugira ubusumbane buke bwo kugorora ahubwo ko zifite intera iringaniye neza kuri buri gice cy’ubuso bwazo.
Igipimo cy'Ubuziranenge ku Isi
Ububasha bw'ibi bikoresho bisa n'ibyoroshye buri mu cyemezo cyabyo. Abakora ibikoresho bakorera ku rwego rwo hejuru mu nganda zikora neza bagomba kubahiriza no kurenza amahame mpuzamahanga menshi y'ibipimo (nka DIN, ASME, JIS, na GB). Uku kwiyemeza kubahiriza ibipimo ngenderwaho ni icyizere kitaziguye ku bakiriya bo ku isi yose—kuva ku nganda zikora imodoka zo mu Budage kugeza ku nganda zo mu kirere zo muri Amerika—ko ukuri kw'imiterere y'ikirere gusobanurwa n'umurongo ugororotse wa granite ufite ubuso bubiri bwiza bwemezwa ku isi yose.
Byongeye kandi, iyi gahunda yo kwemeza isaba umuco wo kugira ireme ritajegajega. Ibi bivuze ko uburyo buri gice gikoresha neza atari umusaruro w'ibikoresho byo gukata bigezweho gusa, ahubwo ni ugukora neza kwa nyuma gutangwa n'abahanga mu gukata intoki bafite uburambe buhanitse. Aba banyabukorikori, akenshi bafite uburambe bw'imyaka irenga mirongo itatu, bakoresha ubuhanga bwabo bwo gukoraho kugira ngo bakureho ibikoresho ku rwego rwa micro-one, bageza granite ku rugero rwayo rwa nyuma rwemewe. Ubu buhanga bw'abantu, hamwe no kugenzura hakoreshejwe sisitemu zigezweho zo gupima zidahuye nka laser interferometers, ni byo biha ibi bikoresho bya granite ububasha bwabyo busesuye kandi budasubirwaho mu isi yo gukora neza cyane.
Ubudahangarwa bworoheje kandi budahinduka bw'amabuye, butunganywa hakurikijwe amahame akomeye ya metrologie igezweho, buracyari inkingi y'ingenzi mu isi y'ubukorikori bw'ingufu za nanometero zigenda zihinduka.
