Uburyo bwo gupima neza granite

Ikoranabuhanga ryo gupima granite - rijyanye neza na micron

Granite yujuje ibisabwa mu ikoranabuhanga rigezweho ryo gupima mu ikoranabuhanga rya mekanike. Ubunararibonye mu gukora intebe zo gupima no gupima hamwe n'imashini zipima byagaragaje ko granite ifite ibyiza bidasanzwe ugereranyije n'ibikoresho gakondo. Impamvu ni iyi ikurikira.

Iterambere ry'ikoranabuhanga ryo gupima mu myaka ya vuba aha n'imyaka ibarirwa muri za mirongo riracyashimishije na n'ubu. Mu ntangiriro, uburyo bworoshye bwo gupima nk'ibibaho byo gupima, intebe zo gupima, intebe zo gupima, nibindi byari bihagije, ariko uko igihe cyagendaga gihita, ibisabwa kugira ngo umusaruro ube mwiza kandi wizewe byarushijeho kwiyongera. Ubuziranenge bwo gupima bugenwa n'imiterere y'urupapuro rwakoreshejwe ndetse n'uburyo bwo gupima budasobanutse neza bw'imashini ipima. Ariko, imirimo yo gupima irarushaho kuba ingorabahizi kandi ihindagurika, kandi ibisubizo bigomba kuba bisobanutse neza. Ibi bigaragaza ko hatangiye gutegurwa uburyo bwo gupima ibintu mu buryo bw'ikirere.

Gukoresha ukuri bivuze kugabanya uruhande rubogamiyeho
Imashini ipima ibintu mu buryo bwa 3D igizwe na sisitemu yo gushyira ibintu aho biri, sisitemu yo gupima ifite ubushobozi bwo hejuru, sensor zo gupima cyangwa gupima, sisitemu yo gusuzuma na porogaramu yo gupima. Kugira ngo hagerwe ku buziranenge bwo gupima, gutandukanya ibipimo bigomba kugabanywa.

Ikosa ryo gupima ni itandukaniro riri hagati y'agaciro kagaragazwa n'igikoresho gipimisha n'agaciro nyakuri k'ingano ya geometrike (igipimo ngenderwaho cyo gupima). Ikosa ryo gupima uburebure E0 ry'imashini zipima zigezweho (CMMs) ni 0.3+L/1000µm (L ni uburebure bwapimwe). Igishushanyo mbonera cy'igikoresho gipimisha, probe, ingamba zo gupima, igikoresho cyo gukora n'umukoresha bigira ingaruka zikomeye ku gutandukana kw'uburebure. Igishushanyo mbonera cya mekanike ni cyo kintu cyiza kandi kirambye gitera ingaruka.

Ikoreshwa rya granite muri metrology ni kimwe mu bintu by'ingenzi bigira ingaruka ku miterere y'imashini zipima. Granite ni ibikoresho byiza cyane ku bisabwa muri iki gihe kuko yujuje ibisabwa bine bituma ibisubizo biba byiza kurushaho:

1. Ubudahangarwa buri hejuru
Granite ni ibuye ry’ibirunga rigizwe n’ibice bitatu by’ingenzi: quartz, feldspar na mica, rikorwa no gushonga kw’amabuye mu gice cy’urukuta.
Nyuma y'imyaka ibihumbi "ishaje", granite ifite imiterere imwe kandi nta stress imbere. Urugero, impala zifite imyaka igera kuri miliyoni 1.4.
Granite ifite ubukana bukomeye: 6 ku gipimo cya Mohs na 10 ku gipimo cy'ubukana.
2. Kurwanya ubushyuhe bwinshi
Ugereranyije n'ibikoresho by'icyuma, granite ifite igipimo cyo kwaguka kiri hasi (hafi 5µm/m*K) n'igipimo cyo kwaguka burundu kiri hasi (urugero: icyuma α = 12µm/m*K).
Ubushyuhe buke bwa granite (3 W/m*K) butuma habaho igisubizo gito ku ihindagurika ry’ubushyuhe ugereranije n’icyuma (42-50 W/m*K).
3. Ingaruka nziza cyane zo kugabanya gutigita
Bitewe n'imiterere imwe, granite nta kintu na kimwe gisigaye igira. Ibi bigabanya gutigita.
4. Inzira y'ubuyobozi ifite imirongo itatu ikora neza cyane
Granite, ikozwe mu ibuye rikomeye karemano, ikoreshwa nk'isahani yo gupimisha kandi ishobora gukorerwa imashini neza cyane hakoreshejwe ibikoresho bya diyama, bigatuma ibice by'imashini bitanga ubuziranenge bw'ibanze.
Ukoresheje intoki, uburyo bwo gusya neza bushobora kunozwa kugeza ku rwego rwa mikoroni.
Mu gihe cyo gusya, imiterere y'ibice ishingiye ku mutwaro ishobora kwitabwaho.
Ibi bituma ubuso bukomera cyane, bigatuma hakoreshwa imirongo iyobora umwuka. Imirongo iyobora umwuka ikora neza cyane bitewe n'ubwiza bw'ubuso n'ingendo z'umugozi zidakora.

mu gusoza:
Ubudahangarwa bw’ibanze, kudahangana n’ubushyuhe, kudahusha no kudahusha neza kw’umurongo w’ubuyobozi ni byo bintu bine by’ingenzi bituma granite iba ibikoresho byiza kuri CMM. Granite ikoreshwa cyane mu gukora intebe zo gupimisha no gupima, ndetse no kuri CMM zo gupimisha imbaho, ameza yo gupimisha n’ibikoresho byo gupimisha. Granite ikoreshwa kandi mu zindi nganda, nko mu bikoresho by’imashini, imashini za laser na sisitemu, imashini zikora micromachining, imashini zicapa, imashini zikoresha urumuri, ikoranabuhanga ryo guteranya, gutunganya semiconductor, nibindi, bitewe n’uko ibisabwa ku mashini n’ibice by’imashini byiyongera.
