Mu isi ikomeye yo gukora ibintu bigezweho, aho ndetse no kunyuranya na mikorometero bishobora kwangiza umutekano cyangwa imikorere, igikoresho kimwe ntawe ugishidikanyaho nk'icyitegererezo cy'ukuri: icyuma cyo hejuru cya granite cya grade 00. Kuva ku igenzura ry'ibice by'indege kugeza ku igeragezwa ry'umunaniro w'amagare, ibi bisate by'amabuye yakozwe neza byahindutse intwari zitari zizwi mu ikoranabuhanga rya none. Ariko se ni iki gituma ibi bikoresho bya kera—byakozwe mu isi mu myaka ya za miriyoni—biba ingenzi mu nganda zo mu kinyejana cya 21? Kandi kuki inganda kuva ku modoka kugeza ku zikora semiconductor zikomeje kwishingikiriza ku bice bya granite kuruta ibindi byuma bisanzwe?
Ubumenyi bw'ibuye: Impamvu Granite yiganje mu gupima neza
Munsi y'ubuso busesuye bwa buri santimetero ya granite yo mu rwego rwa 00 hari ikintu cy'ingenzi cya geologiya. Yakozwe mu buryo butuma magma ihinduka buhoro buhoro mu gihe cy'umuvuduko ukabije, imiterere yihariye y'amabuye y'agaciro ya granite—25-40% ya quartz, 35-50% ya feldspar, na 5-15% ya mica—irema ibintu bifite imiterere idasanzwe. “Imiterere ya kristali ya granite ihuza iratanga ubuziranenge budasanzwe,” ibi ni ibyasobanuwe na Dr. Elena Marchenko, umuhanga mu by'ibikoresho muri Precision Metrology Institute. “Bitandukanye n'icyuma gishongeshejwe, gishobora kugorama mu gihe cy'ihindagurika ry'ubushyuhe cyangwa kikabyara uduce duto duturuka ku munaniro w'icyuma, imihangayiko y'imbere ya granite yagabanutse mu buryo busanzwe mu myaka ibihumbi.” Uku guhagarara gupimwe muri ISO 8512-2:2011, amahame mpuzamahanga agena ubushobozi bwo kwihanganira uburebure bw'isahani ya 00 kuri ≤3μm/m—hafi 1/20 cy'umurambararo w'umusatsi w'umuntu mu burebure bwa metero imwe.
Imiterere y'imiterere ya granite igaragara nk'urutonde rw'ibyo injeniyeri yifuza. Ifite ubukana bwa Rockwell bwa HS 70-80 n'imbaraga zo gukanda kuva kuri 2290-3750 kg / cm², irusha icyuma gikozwe mu cyuma ku rugero rwa 2-3 mu kudashira. Ubucucike bwayo, bwagaragajwe kuri ≥2.65g / cm³ na ASTM C615, butanga uburyo budasanzwe bwo kudasimbuka - ni ingenzi ku bipimo byoroheje aho ndetse n'ihindagurika rya microscopic rishobora kwangiza amakuru. Ahari icy'ingenzi cyane ku ikoreshwa rya metrology, granite ntabwo ikoresha ingufu za rukuruzi kandi ntihindagurika mu bushyuhe, ifite coefficient yo kwaguka hafi 1/3 cy'icyuma. "Muri laboratwari zacu zigenzura semiconductor, ubushyuhe burahamye ni cyo kintu cyose," Michael Chen, umuyobozi ushinzwe kugenzura ubuziranenge muri Microchip Technologies, agira ati: "Isahani y'ubuso bwa granite ifite urwego rwa 00 ikomeza kuba ndende muri 0.5μm hejuru y'ubushyuhe bwa dogere selisiyusi 10, bidashoboka iyo ikoresheje ibyuma."
Ibikoresho by'imigozi n'ubuziranenge bw'imiterere: Ubuhanga bwa Granite mu nganda zigezweho
Nubwo granite karemano itanga substrate nziza yo gupima neza, kuyishyira mu nganda bisaba ubuhanga bwihariye. Ibyuma bifatanye mu migozi—ibifunga by'icyuma bishyirwa mu ibuye—bihindura plaque zo hejuru zidafite imigozi mo ibyuma bikora neza bishobora gufata ibikoresho, jigs, n'ibikoresho byo gupima. James Wilson, injeniyeri w'ibicuruzwa muri Unparalleled Group, uruganda rukora ibikoresho bya granite ruzwi cyane, agira ati: “Ibitandukanye n'ibyuma, ntushobora gukanda imigozi muri granite gusa. Uburyo bubi butera gucika cyangwa kwangirika.”
Sisitemu zigezweho zo gushyiramo imigozi, nka KB self-locked press-fit ibiti biva muri AMA Stone, zikoresha ihame ryo gufunga aho gukoresha kole. Izi mashini zishyiramo ibyuma bitagira umugese zifite amakamba afite amenyo aruma granite iyo ikandagiwe, bigatuma habaho isano ikomeye ifite ubushobozi bwo kuyikuramo kuva kuri 1.1kN kugeza kuri 5.5kN bitewe n'ingano yayo. Wilson asobanura ati: “Imashini zacu za M6 zifite amakamba ane zigira imbaraga zo gukurura 4.1kN muri granite ifite ubugari bwa mm 12. Ibyo birahagije kugira ngo ibikoresho biremereye bigenzurwe nta ngaruka zo gucika uko igihe kigenda gihita.” Uburyo bwo gushyiraho busaba gucukura imyobo ihamye (ubusanzwe ifite umurambararo wa mm 12) hagakurikiraho gukanda hakoreshejwe inyundo ya rubber—uburyo bwakozwe kugira ngo hirindwe kuvunika kw'ibuye.
Ku bijyanye n'ibikoresho bisaba kuvugururwa kenshi, abakora ibikoresho batanga amasafuriya y'ubuso bwa granite afite imiyoboro ya T—imiyoboro ifite icyuma gikozwe neza kandi ifasha ibikoresho kugenda neza. Iyi miyoboro ishyigikiwe n'icyuma ikomeza kuba ndende mu gihe itanga uburyo bwo gukora ibintu bigoye. “Isafuriya y'ubuso ya granite ya santimetero 24 na 36 ifite imiyoboro ya T iba urubuga rwo gupima,” uko ni ko Wilson abivuga. “Abakiriya bacu b'indege bakoresha ibi bikoresho mu kugenzura ibyuma bya turbine, aho bakeneye gushyira ibikoresho ku mfuruka nyinshi badahungabanyije uburyo bwo kubigaragaza.”
Kuva kuri Laboratwari kugeza ku murongo w'umusaruro: Imikoreshereze nyayo y'ibice bya Granite
Igipimo nyacyo cy'agaciro ka granite kiri mu ngaruka zayo ku mikorere y'igare. Mu gukora ibice by'amagare, aho ibikoresho byoroheje nka fibre ya karubone bisaba isuzuma rikomeye ry'umunaniro, amasahani ya granite atanga ishingiro rihamye ryo gusesengura stress. “Dupima amasahani ya fibre ya karubone dukoresha imitwaro igera kuri 1200N ku nshuro 100.000,” ibi ni ibyasobanuwe na Sarah Lopez, injeniyeri w'ibizamini muri Trek Bicycle Corporation. “Isahani ishyirwa ku isahani ya granite yo mu rwego rwa 0 ifite ibikoresho byo gupima. Iyo hatabayeho kunyuranya kw'isahani, twabona ibimenyetso by'umunaniro bitari byo bivuye ku mashini.” Amakuru y'ibizamini bya Trek agaragaza ko ibikoresho bishingiye kuri granite bigabanya itandukaniro ry'ibipimo ho 18% ugereranije n'ameza y'icyuma, bigatuma umusaruro wizewe.
Inganda zikora imodoka nazo zishingikiriza kuri granite kugira ngo zikore neza. Uruganda rwa BMW rwa Spartanburg rukoresha plaque zisaga 40 za granite mu buryo bwa A mu gukora moteri, aho zemeza ko imitwe ya silinda iri hagati ya 2μm. Karl-Heinz Müller, umuyobozi ushinzwe inganda muri BMW, agira ati: “Ubuso bw’umutwe wa silinda bugomba gufunga neza.” “Ubuso bugoramye butera gusohora amavuta cyangwa gutakaza imbaraga. Plaque zacu za granite ziduha icyizere cy’uko ibyo dupima ari byo tubona muri moteri.” Ibipimo by’ubuziranenge bw’uru ruganda bigaragaza ko garanti igabanukaho 23% bitewe n’igabanuka ry’imitsi yo mu mutwe nyuma yo gushyira mu bikorwa sisitemu zo kugenzura zishingiye kuri granite.
Ndetse no mu ikoranabuhanga rigezweho nko gukora inyongeramusaruro, granite igira uruhare runini. Ibiro bishinzwe icapiro rya 3D Protolabs bikoresha amapine ya granite yo mu rwego rwa 00 kugira ngo bitunganye imashini zayo zicapa, bigenzura ko ibice byujuje ibisabwa mu bunini bw'ibikoresho kugeza kuri metero kibe imwe. "Mu icapiro rya 3D, ubuziranenge bw'ibice bushobora kunyerera bitewe n'ubushyuhe," uyu ni Ryan Kelly, injeniyeri wa porogaramu za Protolabs. "Ducapa buri gihe ikintu gipima kandi tukagisuzuma ku ipine yacu ya granite. Ibi bidufasha gukosora imashini iyo ari yo yose inyerera mbere yuko igira ingaruka ku bice by'abakiriya." Isosiyete ivuga ko ubu buryo bugumana ubuziranenge bw'ibice muri ± 0.05mm ku bice byose byacapwe.
Ubunararibonye bw'umukoresha: Impamvu injeniyeri zikunda Granite mu mikorere ya buri munsi
Uretse ibisobanuro bya tekiniki, amasafuriya y’ubuso bwa granite yihesheje izina ryayo mu myaka myinshi ikoreshwa mu buryo bufatika. Isuzuma ry’abakiriya rya Amazon Industrial ry’inyenyeri 4.8 rigaragaza ibyiza bifatika bihurirana n’abahanga n’abatekinisiye. Umuguzi umwe wemewe yaranditse ati: “Ubuso budafite imyenge buhindura ibintu mu maduka.” “Amavuta, icyuma gikonjesha, n’amazi yo gusukura bihanagurwa neza nta maranga-ikintu amasafuriya y’icyuma adashobora gukora.” Undi musesenguzi avuga ibyiza byo kubungabunga: “Maze imyaka irindwi mfite iyi safuriya, kandi iracyakomeza gupimwa. Nta ngese, nta gusiga irangi, ahubwo ni ugusukura rimwe na rimwe nkoresheje isabune idakoresha ikoranabuhanga.”
Ubunararibonye bwo gukora kuri granite butuma abantu bayihindura. Ubuso bwayo bworoshye kandi bukonje butanga urubuga ruhamye rwo gupima neza, mu gihe ubucucike bwayo karemano (ubusanzwe buri hagati ya 2700-2850 kg / m³) buyiha imbaraga zihagije zigabanya ingendo zitunguranye. Thomas Wright, umuyobozi w’ubugenzuzi bw’ubuziranenge umaze imyaka 40 mu kazi, agira ati: “Hari impamvu laboratwari zipima ubuziranenge zakoresheje granite kuva kera.” “Ntabwo isaba guhora uyikoresha nk’icyuma gikozwe mu cyuma. Ushobora gushyiraho igipimo cy’ubuziranenge utitaye ku gusya ubuso, kandi impinduka z’ubushyuhe mu iduka ntizikuraho ibipimo byawe.”
Ku bantu bahangayikishijwe n'uburemere—cyane cyane ku masahani manini—abakora batanga amasahani akozwe neza kandi yoroshya uburyo bwo kuyakoresha ariko agakomeza kumererwa neza. Ubusanzwe aya masahani afite uburyo bwo kuyashyigikira bufite ingingo eshanu hamwe n'ibice byo kugena aho ahagarara, bigatuma ahora ahagaze neza ndetse no ku masahani adahuye. Wilson wo muri Unparalleled Group agira ati: “Isahani yacu ya santimetero 48 x 72 ipima ibiro bigera kuri 1200.” “Ariko iyo umuntu ahagaze neza, abantu babiri bashobora kuyapima neza mu minota iri munsi ya 30.” Amasahani kandi azamura isahani ku burebure bwo gukora neza (ubusanzwe santimetero 32-36), bigabanya umunaniro w'umukoresha mu gihe cyo gupima igihe kirekire.
Akamaro k'Uburambe: Uburemere bw'ibidukikije bwa Granite mu nganda
Mu gihe cy’uburambe bukomeje kwiyongera, ibice bya granite bitanga inyungu zitunguranye ku bidukikije ugereranije n’ibindi byuma. Uburyo bwo gukora granite karemano bukuraho ikorwa ry’ibyuma cyangwa ibyuma bikoresha ingufu nyinshi. “Kugira ngo ukoreshe icyuma gishongeshejwe hejuru bisaba gushonga ubushyuhe bwa 1500°C, bitanga imyuka myinshi ya CO2,” ibi ni ibyasobanuwe n’umuhanga mu by’ibidukikije Dr. Lisa Wong wo mu Kigo Gishinzwe Ubucuruzi bw’Ibidukikije. “Amasahani ya granite, ku buryo butandukanye, akeneye gukatwa, gusya no gusya gusa—ibikorwa bitwara ingufu nkeya kuri 70%.
Kuramba kwa Granite kurushaho kunoza imiterere yayo mu bidukikije. Isahani y’ubuso bwa granite ibungabunzwe neza ishobora kumara imyaka 30-50, ugereranyije n’imyaka 10-15 ku masahani y’icyuma akozwe mu byuma ahura n’ingese n’ubusaza. Dr. Wong agira ati: “Isesengura ryacu rigaragaza ko amasahani ya granite agira 1/3 cy’ingaruka ku bidukikije ku buryo ibyuma bisimbura ibindi bikoreshwa mu byuma.” “Iyo ushyize mu bikorwa ikiguzi cyo gusimbuza no kugabanya ikoreshwa ry’ibikoresho, ikibazo cyo kubungabungwa kirarushaho kuba cyiza.”
Ku bigo bikora icyemezo cya ISO 14001, ibice bya granite bigira uruhare mu ntego nyinshi zo kubungabunga ibidukikije, harimo kugabanya imyanda iva mu bikoresho byo kubungabunga no kugabanya ikoreshwa ry'ingufu mu kugenzura ikirere. “Kuba ubushyuhe bwa Granite buhagaze neza bivuze ko dushobora kubungabunga laboratwari yacu yo gupima ubushyuhe kuri 22±2°C aho kuba 20±0.5°C isabwa ku byuma,” nk'uko bivugwa na Michael Chen wo muri Microchip. “Ubwo buryo bwo kwihanganira 1.5°C bugabanya ikoreshwa ryacu ry'ingufu za HVAC ho 18% buri mwaka.”
Gutanga Icyitonderwa: Igihe cyo Gushora imari mu cyiciro cya 00 ugereranije n'icya Granite yo mu rwego rw'ubucuruzi
Kubera ko ibiciro biri hagati ya $500 ku mapine mato ya B kugeza ku $10.000 ku mapine manini ya laboratwari ya 00, guhitamo plate nziza ya granite bisaba guhuza ibikenewe mu buryo bunonosoye ugereranije n'ingengo y'imari. Ikintu cy'ingenzi ni ukumva uburyo ibisabwa mu buryo bunonosoye bihindura imikorere y'isi isanzwe. “Impamyabumenyi ya 00 ni ingenzi muri laboratwari zo gupima aho ugenzura ibipimo by'imashini cyangwa ushyiraho amahame shingiro,” Wilson aratanga inama. “Ariko imashini igenzura ibice byayo ishobora gukenera grade A gusa, itanga ubugari buri hagati ya 6μm/m—ihagije cyane ku bipimo byinshi.”
Imbonerahamwe y'ibyemezo akenshi ishingiye ku bintu bitatu: ibisabwa mu gupima ibintu bidasobanutse, kudahindagurika kw'ibidukikije, n'igihe cy'ubuzima giteganijwe. Ku bikorwa by'ingenzi nko kugenzura imashini zipima umuriro, aho hakenewe ubuziranenge bw'urwego rwa nanometero, ishoramari mu cyiciro cya 00 ntirishobora kwirindwa. Chen yemeza ati: "Dukoresha plaque za 00 kuri sisitemu zacu zo guhuza lithography. Ubugari bwa ± 0.5μm bugira uruhare rutaziguye mu bushobozi bwacu bwo gucapa imiyoboro ya 7nm."
Ku nganda rusange, plaque zo mu rwego rwa A zitanga agaciro keza cyane. Izi plaque zigumana ubugari bwa 6μm/m mu burebure bwa metero 1—zihagije cyane mu kugenzura ibice by'imodoka cyangwa ibikoresho by'ikoranabuhanga. Wilson agira ati: “Plaque zacu zo mu rwego rwa A za santimetero 24 x 36 zitangirira ku $1,200.” “Ku iduka ry’akazi rikora igenzura rya mbere, ni igice gito ugereranyije n’ikiguzi cy’imashini ipima, nyamara ni ryo shingiro ry’ibipimo byazo byose byakoreshejwe n’intoki.”
Iby'ingenzi mu kubungabunga: Kubungabunga ubuziranenge bwa Granite mu myaka ibarirwa muri za mirongo
Nubwo granite iramba, kuyibungabunga neza ni ngombwa kugira ngo igumane ubuziranenge bwayo. Abanzi bayo bakomeye ni ibintu bihumanya, ibyamenetse mu binyabutabire, no kuyikoresha nabi. Wilson araburira ati: “Ikosa rikomeye mbona ni ugukoresha imashini zisukura cyangwa ubwoya bw’icyuma. Ibyo bishobora gushwanyaguza ubuso butoshye kandi bigatera ibipimo byinshi.” Ahubwo, abakora batanga inama ku bikoresho bisukura bidafite pH byakorewe granite, nka SPI's 15-551-5 surface plate cleaner, ikuraho amavuta n’ibikonjesha mu buryo bwizewe nta kwangiza ibuye.
Kwita ku buzima bwa buri munsi bikubiyemo guhanagura ubuso ukoresheje igitambaro kidafite irangi n'isabune yoroheje, hanyuma ukamunika neza kugira ngo wirinde amazi. Ku byanduza byinshi nk'amazi ya hydraulic, agace gato ka soda yo gutekesha n'amazi gashobora gukuramo amavuta nta miti ikaze. Lopez wo muri Trek Bicycle agira ati: “Dutoza abakora gukoresha plate ya granite nk'igikoresho gikwiye. Nta gushyiraho ibikoresho neza, buri gihe ukoresha agatambaro gasukuye, kandi ugapfuka isahani iyo udakoreshwa.”
Gupima buri gihe—ubusanzwe bikorwa buri mwaka ku bidukikije by’umusaruro no mu ma laboratwari kabiri mu mwaka—bituma icyuma gikomeza kuba gihagaze neza. Ibi bikubiyemo gukoresha ibyuma bipima ubugari bwa laser cyangwa ibyuma bipima ubugari kugira ngo hamenyekane aho ubuso bunyura. Wilson agira ati: “Gupima umwuga bitwara $200-300 ariko bigafata ibibazo mbere yuko bigira ingaruka ku bwiza bw’ibicuruzwa.” Inganda nyinshi zitanga serivisi zo gusuzuma zikurikije amahame ya NIST, zitanga inyandiko zisabwa kugira ngo ISO 9001 ishyirwe mu bikorwa.
Ahazaza h'Ubuhanga: Udushya mu Ikoranabuhanga rya Granite
Uko ubushobozi bwo gukora ibintu bukomeza kugabanuka, ikoranabuhanga rya granite ririmo gutera imbere kugira ngo rihure n'ibibazo bishya. Udushya duherutse kuvugururwa turimo inyubako za granite zivanze—amabuye ashimangiwe na fibre ya karuboni kugira ngo yongere gukomera—n'ibikoresho bihuza sensor bigenzura ubushyuhe bw'ubuso n'ubugari mu gihe nyacyo. Wilson yagize ati: “Turimo gukora amasahani meza ya granite afite thermocouples zifatanye.” “Ibi bizamenyesha abakora ku bushyuhe bushobora kugira ingaruka ku bipimo, bitange urundi rwego rwo kwemeza ubuziranenge.”
Iterambere mu gutunganya no gukoresha granite ririmo kwagura ikoreshwa ryayo rirenze plaque zisanzwe. Ibigo 5-axis CNC bikora ibikoresho bigoye bya granite nk'intebe z'izuba n'ibikoresho by'imashini bifite ubushobozi bwo kwihanganira ibice by'icyuma mbere. Wilson agira ati: “Ibigo byacu by'imashini bya granite bifite ubushobozi bwo kudakoresha vibration bwa 30% kurusha ibikoresho by'icyuma bikozwe mu cyuma. Ibi bituma ibigo bikora neza ku bice by'izuba.”
Ahari ikintu gishimishije cyane ni ubushobozi bwo kongera gukoresha granite mu nganda zirambye. Amasosiyete arimo gutegura inzira zo kongera gukoresha amabuye y'imyanda ava mu mabuye y'agaciro n'amaduka akora, ayahinduramo amasahani meza binyuze mu guhuza resin. Dr. Wong agira ati: "Izi granite ziyongera gukoreshwa zigumana 85% by'imikorere ya granite karemano ku giciro gito cya 40%. Turi kubona inyungu z'inganda zikora imodoka zishaka kugabanya ingaruka mbi ku bidukikije."
Umwanzuro: Impamvu Granite ikomeje kuba ishingiro ry'Ubuhanga mu by'Ubuhanga
Mu isi ikomeje kwigarurirwa n'ikoranabuhanga rya elegitoroniki, akamaro kanini k'amasahani yo hejuru ya granite kagaragaza uruhare rwayo rw'ibanze mu kwemeza ko ibipimo ari inyangamugayo. Kuva ku masahani yo mu rwego rwa 00 apima ibikoresho bubaka telefoni zacu zigezweho kugeza ku masahani yo mu rwego rwa B agenzura ibice by'amagare mu maduka yo mu gace, granite itanga ikimenyetso kidahinduka gishingira ku buziranenge bwose. Uruvange rwayo rwihariye rw'ubudahangarwa karemano, imiterere ya mekanike, no kuramba kwayo bituma idasimburwa mu nganda zigezweho.
Mu gihe inganda zikomeje gutera imbere mu kugabanya ubushobozi bwo gupima no gukora inganda zigezweho, ibice bya granite bizakomeza gutera imbere—bihujwe n’ikoranabuhanga, ibyuma bipima, n’isesengura ry’amakuru mu gihe bigumana ubuziranenge bw’ubutaka butuma bigira agaciro. Wilson agira ati: “Ejo hazaza h’inganda hubatswe ku byahise. Granite imaze imyaka irenga ijana yizewe, kandi hamwe n’udushya dushya, izakomeza kuba igipimo cya zahabu cyo gupima neza mu myaka ibarirwa muri za mirongo iri imbere.”
Ku bahanga mu by’ubuhanga, abayobozi b’ubuziranenge, n’inzobere mu nganda bashaka kuzamura ubushobozi bwabo bwo gupima, ubutumwa burasobanutse neza: gushora imari mu isafuriya y’agaciro ka granite si ukugura igikoresho gusa—ni ugushyiraho urufatiro rw’ubuhanga buzatanga inyungu mu bisekuruza. Nk’uko umwe mu basesengura isuzuma rya Amazon yabivuze mu magambo make: “Ntugura isafuriya y’akataraboneka gusa. Ushora imari mu bipimo nyabyo by’imyaka myinshi, igenzura ryizewe, n’icyizere mu nganda.” Mu nganda aho ubuziranenge bugaragaza intsinzi, iryo ni ishoramari rihora ritanga inyungu.
