Mu isi ikora cyane mu buhanga bwo gukora ibintu neza cyane, aho sisitemu zikomeye zo gukurikirana imirasire ya laser na algorithms zihambaye zicunga uburyo bwo kugenzura imikorere, bishobora kugaragara nk'ibinyuranyije n'amahame ko ubuziranenge bw'imiterere y'isi bushingira ku bikoresho byo mu minsi ya mbere ya metrology. Nyamara, uko inganda zigenda zirushaho kwibanda ku bice bya sub-micron na nanometer, uruhare rw'ibanze rw'ibikoresho bya granite by'ubuziranenge - cyane cyane granite straight ruler ifite ubuziranenge bwa Grade 00, granite square, nakare ka granite tri—ntibikomeza gusa, ahubwo binarushaho kwiyongera. Ibi bikoresho bidahinduka kandi bidakora ni ingingo z'ingenzi zigaragaza imikorere ya sisitemu zikora neza cyane.
Kuba ibi bikoresho by’icyitegererezo bya granite bikomoka ku ihame ry’ibanze: ubushyuhe n’ubudahangarwa. Imashini iyo ari yo yose yagenewe gukora neza cyane igomba kwemeza ko imiterere yayo yo gupima n’ingendo zayo zigororotse ari ukuri, zigororotse, kandi zigororotse. Iyo inganda zigezweho zisaba ubudahangarwa bw’ibipimo budahungabanywa n’ihindagurika ry’ubushyuhe cyangwa imitingito yo hanze, ibikoresho nk’icyuma cyangwa icyuma gishongeshejwe—bifite ingano yo hejuru y’ubushyuhe (CTE) n’ubushobozi buke bwo kugabanya ubushyuhe—birananirana ikizamini.
Ku rundi ruhande, granite itanga ibidukikije byiza byo gutuza. CTE yayo nke bivuze ko impinduka z'ubushyuhe zitera guhindagurika guke, bigatuma iba ibikoresho byiza byo kugaragaza urwego rw'icyitegererezo rushobora gusobanurwa. Byongeye kandi, ubushobozi bwayo bwo kugabanya ubushyuhe bwinshi butuma ihindagurika ryihuse, bikarinda urusaku n'ijwi ry'ibikoresho by'icyuma, ibi bikaba ari ingenzi cyane muri laboratwari zo gupima no guteranya aho urusaku ruhoraho.
Ishingiro ry'umurongo: Umugenga wa Granite Straight ufite ubuziranenge bwa Grade 00
Gupima ubuziranenge ni inkingi ya mwamba y'ibipimo ngenderwaho. Buri murongo w'ubuyobozi, imiterere y'umwuka, n'umurongo wa CMM bishingiye ku nzira igororotse igenzurwa. Ku bikorwa bigoye cyane, umurongo w'inyuguti ya granite ifite ubuziranenge bwa Grade 00 uba ari wo ugenga byose.
Icyiciro cya 00 (cyangwa impamyabumenyi y’ikirenga ingana nayo) kigaragaza urwego rwo hejuru rw’ubuziranenge bushoboka hanze ya laboratwari z’igihugu zishinzwe ubuziranenge. Uru rwego rw’ubuziranenge rusaba ko ihinduka ry’ubuziranenge ku nkengero zose z’umurabyo rigomba gupimwa mu bice bya mikoroni. Kugira ngo ugere kuri uru rwego rw’ubuziranenge bwa geometrike ntibisaba gusa ibikoresho byiza ahubwo bisaba n’uburyo bwo kubitunganya bugenzurwa neza.
Uburyo bwo gukora bugomba gukurikiza amabwiriza mpuzamahanga akomeye, nka DIN, JIS, ASME, cyangwa GB. Aya mahame mpuzamahanga agenga inzira zo gupima, imiterere y’ibidukikije, n’uburyo bwo kwihanganira ibintu byemewe. Ku bakinnyi bakorera abakiriya mpuzamahanga—kuva ku bigo by’imiti ikoreshwa mu bucuruzi bw’imashini zo mu Buyapani kugeza ku bwubatsi b’ibikoresho by’imashini bo mu Budage—ubushobozi bwo kwemeza icyuma gifata ibara rya granite kinyuranyije n’amahame menshi icyarimwe ni ikimenyetso cy’ubuhanga mu bya tekiniki n’ubuziranenge bwa sisitemu. Akamaro k’iki gikoresho ni akoroshye: gutanga umurongo udahinduka, ushobora gupimwaho ikosa ryo kugororoka ry’umurongo w’imashini uhinduka.
Gusobanura Ubudahangarwa: Granite Square na Granite Tri Square
Nubwo kugororoka ari byo bigena ubwiza bw'imigendere iri ku murongo, kugororoka (cyangwa kare) ni byo bigena imiterere y'imikorere y'imashini. Aho imashini zihurira (nk'imigereka ya X na Y, cyangwa umurongo wa Z ugereranije n'umurongo w'ibanze) bigomba kuba bifite dogere 90 gusa. Guhinduka kose hano, bizwi nka error ya kare, bihindura ikosa ryo mu mwanya, bikongera ingorane zo kugera ku mwanya ukwiye.
Igikari cya granite na granite tri square ni byo bikoresho by'ibanze bikoreshwa mu kugenzura iyi nguni y'ibanze.

Ubusanzwe, aka gace k'amabuye gakoreshwa mu kugenzura ubugari bw'imishumi y'imashini ugereranije n'igice cy'ubuso cyangwa kugenzura ubugari bw'ibice bigize aka gace mu gihe cyo guteranya. Imiterere yako ikomeye ifite ishusho ya L ituma impande zombi zikora zigumana inguni ya 90°.

Akadomo ka granite tri (cyangwa master square) gatanga imiterere yihariye ya geometrike y’impande eshatu, gatuma habaho igenzura ryimbitse ry’imiterere ya cubic mu gitereko cy’imashini. Iyi imiterere ni ingirakamaro cyane mu gushyiraho imbibi za cubic za CMM cyangwa ibyuma binini by’imashini, kwemeza ko indege zose zifatanye kandi zigahuza n’ishingiro.
Kimwe n'umurongo ugororotse, izi kare zigomba kugera ku cyemezo cya Grade 00, bisaba ko inguni ziba zimeze neza mu masegonda arc. Iki gikorwa gishingiye ku buhamye buhebuje bw'ibikoresho bya granite n'ubuhanga budasubirwaho bw'abanyabukorikori b'abahanga bakoresha uburambe bw'imyaka myinshi mu gikorwa cyo gupfunyika intoki kugira ngo bagere ku buso bwa nyuma kandi butunganye.
Urusobe rw'ibinyabuzima by'ubukorikori: Birenze amabuye gusa
Ububasha bw'ibi bikoresho bya granite si mu bikoresho gusa, ahubwo buri mu rusobe rw'ibinyabuzima byose bishyigikira icyemezo cyabyo n'uburyo bikorerwa. Ibigo biyoboye muri uru rwego bisobanukiwe ko gukora neza ari umuco, atari gusa uburyo bigenwa n'ibicuruzwa.
Bitangirira ku banyabukorikori b'abahanga. Mu bigo byihariye kandi bigenzurwa cyane, abahanga mu gusya neza akenshi baba bafite uburambe bw'imyaka mirongo itatu cyangwa irenga. Aba bantu bafite ubuhanga mu gukoresha ibyuma byihariye byo gufunga no gusya kugira ngo bakosore amakosa make n'intoki, akenshi bakora ku buryo amaboko yabo ashobora kubona neza kurusha ibyuma byinshi by'ikoranabuhanga. Ubumenyi bwabo butuma bagera ku buso busunika imbibi z'ubugari n'ubugari, rimwe na rimwe bukagera ku gipimo cya nanometer kugira ngo bugire irangi ryiza cyane risabwa n'ibikoresho by'umwuka. Ubu buhanga bw'abantu ni bwo butandukanya ibintu mu kugera ku bisabwa bikomeye byo mu cyiciro cya 00.
Ubu buhanga bugenzurwa kandi bugenzurwa neza. Urwego rw'inganda rugomba kuba rudahindagurika cyane, rufite ibyumba bisukuye bigenzurwa n'ikirere, ishingiro rya sima irwanya gutigita, n'ibikoresho byihariye byo gupima nka laser interferometers n'urwego rw'ikoranabuhanga ubwabyo bigenzurwa buri gihe kandi bigakurikiranwa na laboratwari z'igihugu zishinzwe ubuziranenge. Ubu bwitange butuma imiterere y'ibice byemewe ikomeza kuba iy'ukuri kuva biva mu ruganda.
Kwishingikiriza kuri ibi bikoresho bya kera ariko byuzuye bishimangira ukuri gukomeye mu buhanga buhanitse cyane: gushakisha umuvuduko uhindagurika n'ubuhanga bwo kubara bigomba guhora bihujwe n'ukuri kw'ubuhanga buhamye kandi bwemezwa. Inyuguti ya granite ifite ubuziranenge bwa Grade 00, kare ya granite, na kare ya granite tri si ibisigazwa by'amateka; ni ibipimo by'ingenzi, bidahinduka byemeza ubuziranenge bw'ubuhanga bw'ejo hazaza. Mu gukomeza gukurikiza cyane ibipimo bya DIN, JIS, ASME, na GB, abakora inzobere bemeza ko ibuye ry'ibanze rikomeza kuba igikoresho cy'ingenzi cyane gishoboka mu gusobanura ukuri kw'ibipimo.
