Mu gihe ibintu bikorwa mu buryo bunoze, aho uburinganire busaba intsinzi, guhitamo ibikoresho by'ibanze byo gupima ni ingenzi cyane. Abahanga mu by'imashini, abahanga mu kugenzura ubuziranenge, n'amatsinda ashinzwe gutanga amasoko bakunze guhura n'ikibazo gikomeye: uburyo bwo kugera ku buziranenge buhanitse cyane nta mafaranga menshi akoreshwa. Igisubizo akenshi kiba mu buhanga bw'igikoresho gisa n'aho cyoroshye—isahani ya granite itunganyeAho kuba inkingi gusa, iki gikoresho ni ikimenyetso cy’uko nta kosa ririho, kandi gusobanukirwa akamaro kacyo ni ingenzi mu kunoza laboratwari iyo ari yo yose igezweho yo gupima.
Ijambo "ameza" rikunze gutuma habaho ishusho y'intebe yoroshye yo gukoreraho, ariko ameza y'ubuso burambuye bwa granite yakozwe kugira ngo ihuze n'ibisabwa bikomeye byo kugenzura imiterere. Ni urwego rw'icyitegererezo, rwagenzuwe kandi rwemejwe ku bipimo mpuzamahanga bikomeye (nka ASME B89.3.7), rwemeza ko habaho itandukaniro riciriritse kandi rishobora gupimwa kuva ku buryo burambuye. Iki cyemezo ni cyo kiyizamura kuva ku buso busanzwe ikajya ku gikoresho cyemewe cyo gupima. Uburyo bwo gukora bunoze busaba abatekinisiye b'abahanga cyane bakora uburyo bwo gufunga ibyuma bitatu, bakareba ko ubuso burangiye butandukana n'ubw'ubuziranenge ku rugero rwa santimetero ntoya gusa, bitewe n'urwego rw'ubuziranenge bukenewe.
Ububasha bw'umwimerere bwa Granite Metrology
Ubuhanga bwa granite, ubusanzwe ikaba ari diabase y'umukara mwinshi cyangwa ibuye ry'umukara rikungahaye kuri quartz, buturuka ku buziranenge bwayo bw'ubutaka. Iyi granite isanzwe itanga inyungu zidasanzwe ugereranyije n'ubuso busanzwe bw'icyuma cyabumbwe cyangwa ceramic, ingenzi cyane mu buryo bunoze. Bitandukanye n'ubuso bw'icyuma, granite igaragaza hysteresis ntoya, bivuze ko igaruka vuba ku ishusho yayo ya mbere nyuma yo gukurwaho umutwaro, bigabanye kugorama kw'igihe gito bishobora kugira ingaruka ku bipimo by'ubushyuhe. Byongeye kandi, Coefficient of Thermal Expansion (CTE) yayo nke itanga ubushyuhe budasanzwe, ituma ihindagurika rito ry'ubushyuhe mu bidukikije bya laboratwari rigira ingaruka zikomeye ku rugero rw'ubugari. Uku guhagarara ntigushobora kuganirwaho kugira ngo hakorwe neza, cyane cyane iyo hakoreshejwe ibikoresho by'ubushyuhe nk'urwego rw'ikoranabuhanga cyangwa interferometer za laser. Imiterere ya granite idakonjesha kandi idafite ubushyuhe nayo yoroshya ibidukikije, ikuraho impungenge ku ngese cyangwa kubangamira ibikoresho byo gupima rukuruzi.
Iyo ikigo gishora imari mu isahani yemewe ya granite, ntabwo baba bagura gusa isahani nini; baba babona igipimo cyizewe kandi gishingiye ku bipimo byose bikorerwa mu buryo bwo kugenzura ubuziranenge. Imiterere y'ibikoresho bya crystalline ituma ubusaza, bushoboka mu myaka ibarirwa muri za mirongo ikoreshwa, butuma habaho gucikagurika kwa microscopic aho kuba plastike cyangwa gukora uduce twazamutse, bigatuma ubuso bupimwa bugumana ubuziranenge bw'igihe kirekire kurusha ibikoresho byoroshye.
Gusesengura Ingano y'Ibiciro bya Granite Surface Plate
Kimwe mu bintu by'ingenzi bigira ingaruka ku byemezo byo kugura ni ikiguzi cya mbere cya granite surface plate. Abashinzwe amasoko bagomba kureba kure y'igiciro cya sticker maze bakabara agaciro kose, karimo kuramba, guhamye, n'ikiguzi cyo kubungabunga ubuziranenge mu gihe cyose igikoresho kimaze. Gusobanukirwa ibintu by'ingenzi bitanga ikiguzi bifasha mu gufata icyemezo cy'ishoramari risobanutse neza.
Igiciro gishingiye ahanini ku bintu bitatu bya tekiniki. Icya mbere, ingano n'uburemere bw'amasahani manini bisaba uburyo bugoye bwo kuyakoresha mu gihe cyo kuyahuza no kuyashakira ibikoresho fatizo byinshi. Icya kabiri, urwego rw'ubuziranenge rukenewe - amasahani yemewe ku rwego rwo hejuru (AA, cyangwa urwego rwa laboratwari) asaba amasaha menshi y'akazi aturutse ku batekinisiye b'abahanga mu gupima. Uyu murimo w'inzobere cyane kandi utwara igihe ni wo ugize itandukaniro rikomeye ry'ibiciro hagati y'icyumba cy'ibikoresho (Icyiciro cya B) n'ikiciro cy'inzobere mu gupima (Icyiciro cya AA). Icya nyuma, gushyiramo ibintu byihariye, nk'ibyuma bikozwe mu buryo bw'ikoranabuhanga byo gushyiraho ibikoresho byihariye, imiyoboro ya T isya neza kugira ngo ikoreshwe mu buryo bugoye, cyangwa uburyo bworoshye bwo koroshya imbere kugira ngo igabanye uburemere mugihe ikomeza gukomera, byose bigira uruhare mu ishoramari rya nyuma.
Mu by’ukuri, plaque idasobanutse neza cyangwa idahamye—akenshi bitewe no kugura moderi ihendutse kandi idafite icyemezo—itera gukora ibice bidahuye n’ibyo iteganya. Ikiguzi gikurikiraho cyo gusimbuza, kongera gutunganya, kugarura abakiriya, no gutakaza ibyemezo by’inganda biruta cyane itandukaniro ry’igiciro cy’plaque y’amabuye y’agaciro kandi yemewe. Kubwibyo, kubona ishoramari rya mbere nk’ubwishingizi burambye mu gihe habayeho ubuziranenge buke n’ibidasobanutse neza bitanga icyerekezo gikwiye cy’ubukungu.
Imbonerahamwe y'Ubuso bwa Granite yo Gusuzuma nk'Umutungo w'Ingamba
Ameza yo kugenzura ubuso bwa granite, nta gushidikanya, ni yo mutima wa laboratwari iyo ari yo yose yizewe yo kugenzura ubuziranenge (QC) cyangwa iy’ibipimo. Inshingano yayo y’ingenzi ni ugutanga urubuga rwiza kandi rudafite aho rubogamiye rw’ibikoresho nyabyo nk’ibipimo by’uburebure, ibimenyetso by’ubugari, ibigereranyo by’ikoranabuhanga, ndetse n’ingenzi cyane, ishingiro ry’imashini zipima (CMMs).
Urugero, ukuri kw'isesengura ryoroheje ry'uburebure rishingiye cyane cyane ku bugari n'ubugari bw'icyapa cy'ubuso ubwacyo. Iyo urwego rw'icyitegererezo rufite umugongo muto cyangwa uhindagurika, iryo kosa ry'ubugenge ryimurwa mu buryo butaziguye kandi rigashyirwa muri buri gipimo gikurikiraho, bigatera gupima ibintu mu buryo bunyuranye. Igenzura risanzwe rishingira ku cyapa kugira ngo gitange urwego rw'icyitegererezo rwa zeru, bigatuma haboneka ibipimo byizewe byo kugereranya hakoreshejwe ibice cyangwa ibipimo by'icyitegererezo. Rikora kandi nk'ahantu h'ibanze ho gushyiraho datum, aho ibintu byose biri ku gikoresho cy'ingenzi bipimwa. Byongeye kandi, mu bikorwa byo mu rwego rwo hejuru, uburemere bunini bw'ameza y'ubuso bw'igorofa ya granite bukora nk'aho ari ho hashyirwa ibintu bihamye, birwanya gutigita kuri CMM cyangwa laser trackers, bigenzura ko n'ibintu bito byo hanze cyangwa imiterere bitabangamira ibipimo by'urwego rwa sub-micron bikorerwa.
Kugira ngo icyuma gikoreshwe mu kugenzura kigumane ubuziranenge bwacyo nk'igikoresho cyo kugenzura, kigomba gushyigikirwa neza. Igikoresho cy'umwuga kandi cyubatswe ku ntego ni ingenzi, cyagenewe gufata icyuma ku ngingo zigabanya stress (zizwi nka Airy points). Gushyira icyuma gikoze neza cyane ku ntebe y'akazi idafite imiterere ihanitse, isanzwe bihita bibangamira ubugari bwemewe bwa icyuma kandi bigatuma imiterere yose y'ibipimo idashoboka. Sisitemu yo gushyigikira ni uburyo bwo kongera ubuziranenge bwa icyuma.
Gukomeza Kwizerwa Gushingiye ku Gupima
Nubwo igihe kirekire cy'ameza y'ubuso bwa granite gihamye, ntabwo kidahungabanywa n'ibintu bikomeye byo gukoreshwa buri gihe. Ndetse n'ibikoresho biramba cyane bishobora kwangirika mu buryo buciriritse. Kubungabunga neza ni ngombwa kandi byoroshye: ubuso bugomba kubungabungwa neza, budafite ivumbi rikabije, imyanda isya, cyangwa ibisigazwa bito bishobora kwangiza ibikoresho byo gupima. Hagomba gukoreshwa gusa ibikoresho byihariye byo gusukura plate y'ubuso. Ingaruka zikomeye ku buryo plate y'ubuso ingana ituruka ku kwangirika gukomeye, ari nayo mpamvu abatekinisiye bashishikarizwa gukoresha ubuso bwose aho kwibanda ku bipimo ahantu hamwe hato.
Ariko, uburyo bwonyine bwo kurinda ishoramari ni ugupima buri gihe kandi bushobora gukurikiranwa. Ubu buryo buhora bugaruka, bugomba gushyirwa mu giciro cy’igihe kirekire cya granite surface plate, ntibushobora kuganirwaho kugira ngo bukomeze kubahiriza amahame mpuzamahanga y’ubuziranenge. Mu gihe cyo gupima, umuhanga mu by’ubumenyi bw’ikirere wemewe akoresha ibikoresho bigezweho, nk’urwego rw’ikoranabuhanga rutunganye cyangwa ibikoresho bya laser, kugira ngo agaragaze ubuso bwose. Bagenzura ko ubugari bwa plate muri rusange, ubushobozi bwo gusubiramo ahantu hatandukanye, n’ubugari bw’ahantu haherereye biguma mu buryo buhamye mu rugero rwagenwe rw’urwego rwayo. Ubu buryo bwo kongera kwemeza butuma plate ikomeza kuba ifite ububasha nk’igipimo cyizewe cyo gupima ikigo, ikarinda ubuziranenge bwa buri gicuruzwa gipimye.
Mu isoko mpuzamahanga rihanganye, inganda zikora ibice byazo mu buryo bwo kwihanganira ibintu zifite ibiciro biri hasi, ubwishingizi buke, kandi abakiriya barushaho kunyurwa. Iyi nyungu ishingiye ahanini ku kugira ishingiro ryizewe cyane ry’ibipimo. Icyemezo cyo kugura plaque ya granite yemewe ni ikoranabuhanga rikomeye, kandi mu gushora imari mu mbonerahamwe y’ubuso bwa granite yemewe kandi ikoreshwa mu kugenzura no kuyihuza n’ubufasha bw’abahanga no kuyigenzura buri gihe, ibikoresho bishobora kwemeza ko amakuru yabyo azaba meza, bigahindura ikiguzi cya mbere kikaba umutungo urambye, w’ibanze ku bwiza no kunguka birambye.
