Nigute dushobora kwemeza neza ukuri? Ingingo zingenzi zitegura mbere yo gupima ibice bya Granite

Muri ultra-precision engineering, igice cya granite nikintu cyibanze cyerekana, gitanga urufatiro rwumutekano kubikoresho bikorera kuri minzani na nanometero. Nubwo bimeze bityo ariko, nibikoresho byavukijwe cyane-ZHHIMG® yacu yuzuye-granite yumukara-irashobora gutanga ubushobozi bwayo bwose mugihe inzira yo gupima ubwayo iyobowe nubumenyi bukomeye.

Nigute abajenjeri na metrologiste bemeza ko ibisubizo byo gupima ari ukuri? Kugera ku bisubizo nyabyo, bisubirwamo mugihe cyo kugenzura no kugenzura bwa nyuma imashini ya granite, ibyuma byo mu kirere, cyangwa imiterere ya CMM bisaba kwitondera byimazeyo mbere yuko igikoresho cyo gupima gikora hejuru. Iyi myiteguro akenshi irakomeye nkibikoresho byo gupima ubwabyo, byemeza ko ibisubizo byerekana mubyukuri geometrike yibigize, ntabwo ari ibidukikije.

1. Uruhare Rwingenzi rwo Gutunganya Ubushyuhe (Igihe Cyuzuye)

Granite ifite Coefficient nkeya idasanzwe yo Kwagura Ubushyuhe (COE), cyane ugereranije nibyuma. Nyamara, ibikoresho byose, harimo na granite yubucucike bwinshi, bigomba guhagarikwa mubushuhe bwumuyaga udasanzwe hamwe nigikoresho cyo gupima mbere yuko igenzura ritangira. Ibi bizwi nkigihe cyo gushira.

Ikintu kinini cya granite, cyane cyane icya vuba cyimuwe kiva mu ruganda kijya muri laboratoire yabigenewe, kizatwara imashanyarazi - itandukaniro ryubushyuhe hagati yacyo, hejuru, na base. Niba gupima bitangiye imburagihe, granite izaguka buhoro buhoro cyangwa igabanuke uko iringaniye, biganisha ku guhora mu gusoma.

• Amategeko agenga igikumwe: Ibice byuzuye bigomba gutura mubipimo byo gupima - ubushyuhe bwacu hamwe n’ubwiherero bugenzurwa n’ubushuhe - mu gihe kinini, akenshi amasaha 24 kugeza kuri 72, bitewe nubunini bwibigize hamwe nubunini. Ikigamijwe ni ukugera kuburinganire bwumuriro, kwemeza ibice bya granite, igikoresho cyo gupima (nka laser interferometer cyangwa urwego rwa elegitoronike), kandi ikirere cyose kiri mubushuhe busanzwe buzwi ku rwego mpuzamahanga (mubisanzwe 20 ℃).

2. Guhitamo Ubuso no Gusukura: Kurandura Umwanzi Ukuri

Umwanda, ivumbi, n imyanda ni abanzi bonyine bakomeye bapimye neza. Ndetse na microscopique agace k'umukungugu cyangwa igikumwe gisigaye kirashobora gukora uburebure buhagaze bwerekana ibinyoma byerekana ikosa rya micrometero nyinshi, bikabangamira cyane gupima uburinganire cyangwa kugororoka.

Mbere yubushakashatsi ubwo aribwo bwose, ibyuma byerekana, cyangwa ibikoresho bipima bishyirwa hejuru:

• Isuku ryuzuye: Ubuso bwibigize, bwaba indege yerekanirwamo cyangwa icyuma cyerekana gari ya moshi, bigomba gusukurwa neza ukoresheje guhanagura neza, kutagira linti hamwe nogukora isuku ryinshi (akenshi inzoga zinganda cyangwa isuku ya granite).
• Ihanagura Ibikoresho: Icyangombwa kimwe ni ugusukura ibikoresho byo gupima ubwabo. Kugaragaza, ibikoresho fatizo, hamwe ninama zubushakashatsi bigomba kuba bitagira inenge kugirango tumenye neza inzira ninzira nziza.

3. Gusobanukirwa Inkunga no Kurekura Stress

Uburyo igice cya granite gishyigikirwa mugihe cyo gupima ni ngombwa. Ibikoresho binini, biremereye bya granite byashizweho kugirango bikomeze geometrie iyo ishyigikiwe ku ngingo zihariye, zibarwa mu mibare (akenshi zishingiye ku ngingo ya Airy cyangwa Bessel kugirango ibe nziza).

• Gushiraho neza: Kugenzura bigomba kubaho hamwe na granite yibice bishingiye kumfashanyo yagenwe na igishushanyo mbonera. Ingingo zingoboka zitari zo zirashobora gutera impagarara zimbere no gutandukana kwimiterere, kuzunguruka hejuru no gutanga gusoma "kutihanganira" gusoma, nubwo ibice byakozwe neza.
• Kunyeganyega Kwigunga: Ibidukikije bipima ubwabyo bigomba kuba byitaruye. Urufatiro rwa ZHHIMG, rugizwe na metero imwe yuburebure bwa anti-vibration hasi hamwe nu mwobo wo kwigunga wa mm 2000, bigabanya kwivanga kw’imitingito no gukanika imashini, bigatuma ibipimo bifatwa ku mubiri uhagaze neza.

4. Guhitamo: Guhitamo Igikoresho Cyiza cya Metrology

Hanyuma, igikoresho gikwiye cyo gupimwa kigomba gutoranywa hashingiwe ku cyiciro gikenewe hamwe na geometrie. Nta gikoresho kimwe cyuzuye kuri buri gikorwa.

• Flatness: Muri rusange uburinganire buringaniye hamwe nuburyo bwa geometrike, Laser Interferometer cyangwa Autocollimator ikemurwa cyane (akenshi ihujwe nUrwego rwa elegitoronike) itanga ibyemezo bikenewe kandi birebire neza.
• Ibyukuri byaho: Kugirango ugenzure imyambarire yaho cyangwa isubirwemo (Subiramo Gusoma Ibyukuri), Urwego Rukuru rwa elegitoronike cyangwa LVDT / Ubushobozi bwibibazo bifite imyanzuro kugeza kuri 0.1 mm ni ngombwa.

Mugukurikiza neza izi ntambwe zo kwitegura - gucunga neza ubushyuhe bwumuriro, kubungabunga isuku, no kwemeza inkunga ikwiye - itsinda ryubwubatsi rya ZHHIMG ryemeza ko ibipimo byanyuma byibigize ultra-precision aribintu byukuri kandi byizewe byerekana ukuri kurwego rwisi rwatanzwe nibikoresho byacu hamwe nabanyabukorikori bacu.
