Mu rwego rw'inganda zikora indege, nta mpungenge y'ikosa ihari. Kuva ku mpande za turbine za moteri ya jet kugeza ku gice cy'icyuma gitera ikirere, buri gice kigomba kuba cyujuje ibisabwa bipimwe muri mikoroni z'umubare umwe. Muri iki gihe gikomeye, ukuri kw'uburyo bwo gukora ni byiza gusa nk'uko ibikoresho bikoreshwa mu kubaka no gupima ibi bice bihagaze. Nubwo porogaramu zigezweho n'ubuyobozi bwa laser bikunze kwiba urumuri, ishingiro ry'ubuhanga bugezweho rishingiye cyane ku bikoresho byamaze igihe kirekire: granite ifite ubuhanga buhanitse.
Ibice bya granite ntibikiri plaque zoroshye zo kugenzura intoki gusa; byahindutse ibintu bigoye kandi byubatse imiterere y’ibikoresho bipima (CMMs), ibyuma bipima vuba cyane, na sisitemu yo guhuza imiterere y’urumuri. Iyi nkuru irasuzuma impamvu granite ikora neza cyane ikomeje kuba ibikoresho by’ingenzi ku nganda z’indege n’uburyo igenzura umutekano n’imikorere y’ikinyagihumbi gitaha cy’indege.
Ishingiro ry'Uburimbane bw'Ibipimo
Ibice by’ikirere akenshi biba binini, bigoye, kandi bikozwe mu bikoresho bigoye gukoresha imashini nka titaniyumu na Inconel. Mu gihe cyo gukora, ibyo bice bihura n’imbaraga nyinshi n’ihindagurika ry’ubushyuhe. Kugira ngo byemezwe ko igice gikwiriye guhumeka, kigomba gupimwa ukurikije urwego rw’ikirere ruhamye kurusha igice ubwacyo. Iki ni igitekerezo cy’"urwego rw’ikirere". Iyo urwego rwo gupima rwagutse, rugahindagurika, cyangwa rukanyeganyega gato, amakuru yakusanyijwe arangirika, bishobora gutuma ibice bifite inenge bishyirwaho.
Granite ifite ubuhanga buhanitse, cyane cyane granite y'umukara ifite ubucucike bwa kilo 3100/m³, itanga igisubizo cyiza cyo kudahinduka. Bitandukanye n'icyuma cyangwa icyuma gishongeshejwe, gishobora kugorama iyo hari stress cyangwa impinduka z'ubushyuhe, granite ikora nk'urufatiro rudafite aho rubogamiye kandi rudahinduka. Itanga "ingingo ya zeru" idahinduka, igenzura ko ibipimo bifatwa n'ibyuma bikurikirana imirasire ya laser cyangwa CMM ari ishusho nyayo y'ukuri. Mu nganda aho guhindagurika kwa mikorosikopi bishobora gutuma umuntu ananirwa cyane, uku kudahinduka si ikintu cy'agaciro gusa - ni ikintu gisabwa mu mutekano.
Gutuza: Umurinzi ucecetse w'ubuziranenge
Imwe mu mbogamizi zikomeye mu nganda zikora indege ni ugucunga ubushyuhe. Inzu nini zikoramo zishobora guhura n'ihindagurika ry'ubushyuhe umunsi wose, kandi uburyo bwo gukora imashini ubwabwo butanga ubushyuhe bukabije. Ibyuma bifite igipimo cyo kwaguka k'ubushyuhe (CTE), bivuze ko bikura iyo bishyushye kandi bigagabanuka iyo bikonje. Iyo ikiraro cya CMM cyangwa imashini ikoze mu cyuma, bizakura uko uruganda rushyuha, bigatuma imashini itakaza ubushobozi bwo kuyipima no guteza amakosa mu gupima.
Granite ifite CTE iri hasi cyane, iri hasi cyane ugereranyije n'iy'icyuma. Iyi miterere karemano ituma idahura n'ihindagurika rito ry'ubushyuhe riboneka mu bidukikije bigenzurwa. Mu gukoresha granite mu bice by'imiterere y'igenzura n'inganda, abahanga mu by'indege bareba ko imiterere y'imashini iguma ihoraho uko ikirere kiba kiri kose. Uku guhagarara kw'ubushyuhe budakora bikuraho gukenera sisitemu zikonjesha kandi zihenze mu bikorwa byinshi, bitanga ibanze ryizewe ryo gukora akazi gakomeye.
Gutemba no kurangiza ubuso bw'inyuma
Ibice by'ikirere akenshi bisaba imiterere y'ubuso nk'indorerwamo hamwe n'imiterere y'ikirere igoye. Kugira ngo ibi bigerweho bisaba ahantu ho gukora imashini hatarangwamo "guhindagura" cyangwa guhindagura. Iyo igikoresho gikata gikoresheje ibikoresho bikomeye nk'igice cya titaniyumu, bitera guhindagura gukomeye. Iyo imiterere y'imashini yinjiza kandi ikagaragaza uku guhindagura, imiterere y'ubuso iragabanuka, kandi ubuzima bw'igikoresho buragabanuka cyane.
Imiterere ya granite ifite kristalo itanga ubushobozi bwo kugabanya ubushyuhe bw'amashanyarazi - kugeza ku nshuro icumi nziza kurusha icyuma. Ibi bivuze ko ibice bya granite bifata ingufu zihindagurika aho kuzikwirakwiza. Mu rwego rw'imashini ya CNC cyangwa scanner ya laser yihuta cyane, ishingiro rya granite rikora nk'ikintu gikomeye gifata ubushyuhe. Ubu bushobozi bwo kugabanya ubushyuhe butuma habaho ubwinshi bw'ibikoresho byo kugaburira no gukata neza, bigatuma ibikoresho byo gukata birangira neza kandi bikagabanya kwangirika kw'ibikoresho bihenze byo gukata. Ku buryo bwo kugenzura amatara, uku guhagarara ni ingenzi cyane; ndetse no guhindagurika guke cyane kw'ibikoresho byo gukata cyangwa HVAC biri hafi bishobora gutuma scan zigaragaza ubushobozi bwo hejuru, bigatuma amakuru adakoreshwa.
Ubushobozi bwo gukomera no gutwara imizigo
Ibikoresho byo mu kirere akenshi biremereye, kandi ibikoresho bikoreshwa mu kubifata ni binini cyane. Urubuga rwa granite rutunganye rugomba gushyigikira iyi mitwaro rudahindagurika. Granite y'umukara ifite ubucucike bwinshi ifite uburyo bworoshye bwo guhindagurika, ibyo bikaba bivuze ko ikomera cyane. Ubu buryo bwo gukomera butuma urubuga ruguma rutambitse ndetse no mu gihe cy'imitwaro iremereye.
Byongeye kandi, granite ntabwo ikoresha ingufu za rukuruzi kandi ntishobora kwangiza. Mu nganda zikora indege, aho ibikoresho by'ikoranabuhanga n'ibikoresho by'ingufu bya rukuruzi bikunze gukoreshwa, imiterere ya granite idakoresha ingufu za rukuruzi irinda ingaruka mbi. Byongeye kandi, bitandukanye n'icyuma gishongeshejwe, granite ntabwo ikoresha ingese. Irwanya ibintu bikonjesha, amavuta, n'ibintu bishongesha bikunze kuboneka ku iduka, bigatuma ubuso bukomeza kuba bwiza mu gihe cy'imyaka myinshi hatabayeho kubungabungwa cyane. Ubu buryo butuma iba ishoramari rihendutse ku buryo bworoshye kuri gahunda z'indege z'igihe kirekire zishobora kumara imyaka makumyabiri cyangwa irenga.
Inganda zigezweho no guhindura ibintu uko bishakiye
Gushaka granite mu by’ikirere byatumye habaho iterambere rikomeye mu buryo ibi bice bikorerwamo. Ntabwo bihagije gukata ibuye rimwe gusa; ibikoresho bigezweho byo mu kirere bisaba ubuhanga buhanitse, ibikoresho byometseho, n’ubugari bwo ku rwego rwa nanometero.
Inyubako zigezweho ubu zikoresha imashini nini zisya zikoresha ikoranabuhanga hanyuma abanyabukorikori b'abahanga bagakoresha intoki kugira ngo bagere ku buremere bwo kugorora ibintu bitari bisanzwe bifatwa nk'ibidashoboka. Izi nzira zemeza ko ibice bya granite byujuje ibisabwa mpuzamahanga nka DIN 876 cyangwa ASME B89.3.7. Byongeye kandi, inganda zirimo kubona icyerekezo cyo kugera ku bipimo binini. Uko inyubako z'indege zigenda zikura—nk'ibice by'amababa by'indege zitwara abagenzi zo mu gisekuru gitaha—ameza yo kugenzura granite arimo kwiyongera, uburebure bumwe ubu bukaba burenga metero 9.
Hari kandi n'icyerekezo gikomeje kwiyongera mu ikoreshwa rya "granite y'ubukorano" cyangwa amabuye y'agaciro mu bikoresho byihariye by'imashini. Ibi bikoresho bihuza granite yasheshwe na epoxy resins kugira ngo bikore inyubako zoroshye kandi zishobora gushyirwa mu buryo bugoye mu gihe zigumana inyungu z'ubushyuhe n'ubukonje bw'amabuye karemano. Ariko, kugira ngo habeho urwego rwo hejuru rw'ibipimo n'ubudahangarwa bw'igihe kirekire, granite y'umukara karemano iguma ari yo ikoreshwa nk'izahabu bitewe n'igihe cyayo cya geology kandi nta stress ifite.
Uruhare rw'Impamyabumenyi n'Ikurikiranwa ry'Ibintu
Mu rwego rw'indege, inyandiko ni ingenzi kimwe n'igice gifatika. Igice cyose cya granite gikoreshwa mu kwemeza ibice by'ingenzi mu ndege kigomba kuba cyemejwe. Ibi bisaba igeragezwa rikomeye muri laboratwari zigenzurwa n'ikirere kugira ngo harebwe ko ari ndende, ko ari ndende, kandi ko ari ndende.
Abakora bagomba gutanga ibyemezo byo gupima ibintu bikurikije amahame y’igihugu n’amahanga (nka NIST cyangwa PTB). Uru ruhererekane rw’amabwiriza rugaragaza ko "umugaba" ukoreshwa mu gupima igice cy’indege ari ukuri. Iyo hatabayeho uku gupima ibintu, amakuru yakozwe na CMM cyangwa icyuma gikurikirana ibintu muri laser nta gaciro aba afite. Abatanga granite bakomeye ubu bakorera mu bidukikije byemejwe na ISO, bagenzura ko ibice batwara bidafite stress imbere kandi biteguye guhita byinjizwa muri sisitemu zikora neza cyane.
Umwanzuro
Mu gihe ubwubatsi bw'indege bukomeza imipaka y'umuvuduko, imikorere myiza, no gukoresha lisansi mu buryo buciriritse, ibice bigize izi ndege bigomba kuba byoroshye kandi bikomeye, bigasaba ubushobozi bwo kwihanganira gukora ibintu bikomeye. Ibice bya granite bitanga urufatiro rutuje kandi ruhamye rwubatsweho iyi ntambwe. Mu gutanga ubushyuhe budashobora kugereranywa, kudahindagurika kw'ingufu, no gukomera gukomeye, granite igenzura ko ibikoresho bikoreshwa mu kubaka no kugenzura indege zacu ari byiza nk'ubw'ubuhanga bwazishushanyije. Mu gushaka ubwiza mu kirere, inganda zikomeje guhagarara ku butaka bukomeye—mu buryo bufatika.
