Byuzuye Cmm hamwe nubuyobozi gupima gupima

Imashini ya cmm niyihe?

Tekereza imashini yuburyo bwa cnc ishoboye gukora ibipimo nyabyo muburyo bwikora. Nibyo imashini za CMm zikora!

Cmm igereranya "imashini yo gupima imashini". Birashoboka ko ibikoresho byanyuma bya 3D bikoreshwa mubijyanye no guhuza burundu, ukuri, n'umuvuduko.

Porogaramu yo Guhuza Imashini Gupima

Guhuza imashini gupima bifite agaciro igihe icyo aricyo cyose gikeneye gukorwa. N'ibipimo bigoye cyangwa byinshi, ni byiza gukoresha Cmm.

Mubisanzwe Cmm ikoreshwa mugufashwa no kugenzura ubuziranenge. Ni ukuvuga, bakoreshwa mu kugenzura igice cyujuje ibisabwa nuwashizeho ibintu.

Barashobora kandi kumenyeraHindura injeniyeriIbice bihari mu gupima neza kubiranga.

Ninde wahimbye imashini za Cmm?

Imashini za mbere za CMM zateguwe na Ferranti shingiro rya Scotland muri za 1950. Bari bakeneye gupima ibice mu karopagace n'inganda. Imashini za mbere cyane zifite amashoka 2 yo kugenda. Imashini 3 za AXIS zatangijwe mu myaka ya za 1960 na DEA yo mu Butaliyani. Igenzura rya mudasobwa ryaje mu ntangiriro ya za 70, kandi ryatangijwe na Sheffield wa USA.

Ubwoko bw'imashini za CMM

Hariho ubwoko butanu bwo guhuza imashini yo gupima:

• Bridge Ubwoko bwa CMM: Muri iki gishushanyo, gikunze kugaragara, umutwe wa Cmm ugendera ku kiraro. Uruhande rumwe rw'ikiraro rugendera kuri gari ya moshi ku buriri, naho ubundi rushyigikiwe ku musego wo mu kirere cyangwa ubundi buryo ku buringanire nta gariyari.
• Cantilever Cmm: Cantilever ishyigikira ikiraro kuruhande rumwe gusa.
• Gantry Cmm: Ikando ikoresha gari ya moshi kumpande zombi, nka router ya CNC. Ubusanzwe ni cmm nini ya cmm, kugirango bakeneye inkunga yinyongera.
• Horizontal ART CMM: Shushanya cantilever, ariko hamwe nikiraro cyose kimuka hejuru yintoki aho kuba kuri axis. Ibi nibyinshi cyane bya Cmm, ariko birashobora gupima byinshi binini byarimo bigize nkibiri.
• Ubwiza bw'amaboko ya CMM: Izi mashini zikoresha amaboko yuzuye kandi mubisanzwe uhagaze. Aho gupima xyz mu buryo butaziguye, baratera guhuza umwanya uzunguruka kuri buri guhuriza hamwe hamwe nuburebure buzwi hagati yingingo.

Buriwese afite ibyiza nibibi bitewe nuburyo bwibipimo bigomba gukorwa. Ubu bwoko bwohereza imiterere yimashini ikoreshwa mugushiraikipeugereranije nigice gipima.

Dore ameza yogufasha gusobanukirwa ibyiza nibibi:

Ibibazo bisanzwe bihagaze muri 3 bipimo-x, y, na z. Ariko, imashini zihanitse zirashobora kandi kwemerera inguni yahinduwe yo gupima ahantu hashobora kugeraho. Imbonerahamwe ya Rosery irashobora kandi gukoreshwa mugutezimbere uburyo bwiza bwibintu bitandukanye.

Cmm akenshi ukorwa kuri granite na aluminium, kandi bakoresha ikirere

Iperereza ni sensor igena aho ubuso bwigice aricyo gipimo.

Ubwoko bw'iperereza burimo:

• Imashini
• Optique
• Laser
• Umucyo wera

Imashini zo gupima ibipimo zikoreshwa muburyo bugera kuri bitatu rusange:

• Amashami yo kugenzura ubuziranenge: Hano mubisanzwe babitswe mubyumba bisukuye byimihindagurikire y'ikirere kugira ngo bagabanye neza.
• Igorofa: Hano Cmm iri hasi mumashini ya CNC kugirango byoroshye gukora igenzura nkigice cyimikorere ntarengwa hagati ya Cmm na mashini aho bihabwa. Ibi bituma ibipimo bigomba gukorwa mbere kandi birashoboka cyane ko biganisha ku kuzigama nkuko amakosa yamenyekanye vuba.
• Portable: PORMES CMB yoroshye kugenda. Bashobora gukoreshwa hasi kumaduka cyangwa no gufata kurubuga rwa kure mugice cyo gukora kugirango bapime ibice mumurima.

Nigute imashini za CMM (CMM neza)?

Imashini zo gupima imiyoboro ziratandukanye. Mubisanzwe, bagamije gushira muri micrometero. Ariko ntabwo byoroshye. Kimwe coco, ngaho ikosa rishobora kuba imikorere yubunini, bityo ikosa ryo gupima CMM rishobora kuba ryerekanwe nka formula ngufi ikubiyemo uburebure bwibipimo nkihinduka.

Kurugero, Emblic's Forcel Classic Cmm yashyizwe ku rutonde nka Cmm ihantu heza hose, kandi igaragaza ukuri kwayo nka:

1.0 + l / 300um

Ibyo bipimo biri muri microns kandi l byasobanuwe muri mm. Reka rero tuvuge ko tugerageza gupima uburebure bwikintu cya 10mm. Formula yaba 1.0 + 10/300 = 1.0 + 1/30 cyangwa microns 1.03.

Micron ni igihumbi cya mm, ari hafi 0.00003937. Ikosa rero mugihe ripima uburebure bwa 10mm ni 0.00103 mm cyangwa 0.00004055. Ibyo ni munsi ya kimwe cya kabiri cya cumi-ikosa rito!

Kurundi ruhande, umuntu agomba kugira neza 10x ibyo tugerageza gupima. Bivuze rero niba dushobora kwizera gusa iki gipimo kuri 10x kagaciro, cyangwa 0.00005. Biracyari ikosa rito.

Ibintu bikana no murijier yo hasi ya Cmm ibipimo. Niba CMM irimo gucungwa mubugenzuzi bugenzurwa nubugenzuzi bwa Lab, ifasha cyane. Ariko hejuru yububiko, ubushyuhe burashobora gutandukana cyane. Hariho inzira zitandukanye Cmm irashobora kwishyura itandukaniro ryubushyuhe, ariko ntanumwe utunganye.

Cmm abakora bakunze kwerekana ukuri ku itsinda ryubushyuhe, kandi ukurikije ibipimo bya ISO 10360-2 kuri Cmm neza, itsinda risanzwe ni 64-72f (18-22C). Nibyiza keretse niba amaduka yawe ari 86f mu cyi. Noneho ntufite ikintu cyiza kubwikosa.

Abakora bamwe bazaguha urutonde rwindege cyangwa ubushyuhe bufite ibitekerezo bitandukanye. Ariko bigenda bite iyo uri murwego rwo hejuru rwibice bimwe mubihe bitandukanye byumunsi cyangwa iminsi itandukanye yicyumweru?

Umwe atangira gukora ingengo yimari idashidikanywaho yemerera imanza mbi. Niba ibyo bihe bibi bitera kwihanganira ibitemewe kubice byawe, ibindi birakenewe bikenewe:

• Urashobora kugabanya imikoreshereze ya CMM mugihe runaka cyumunsi mugihe tempiyo igwa muburyo bwiza.
• Urashobora guhitamo imashini gusa ibice cyangwa ibiranga mugihe runaka cyumunsi.
• Nibyiza cmm birashobora kugira ibitekerezo byiza kubushyuhe bwawe. Bashobora kuba bakwiriye nubwo bashobora kuba bahenze cyane.

Nibyo, izo ngamba zizasenyuka kubushobozi bwawe bwo guteganya neza akazi kawe. Mu buryo butunguranye, uratekereza ko kugenzura ibihe byiza biri ku igorofa bishobora kuba ishoramari ryiza.

Urashobora kubona uko ikintu cyose gipima cyose gikura.

Ibindi bigize bijyana nuburyo bwo kwihanganirana na CMM isobanutse. Ibipimo bya zahabu ni Geometrike Dimensinonsing no Guhanganya (GD & T). Reba amasomo yintangiriro kuri GD & T kugirango umenye byinshi.

Cmm software

Cmm ikora ubwoko butandukanye bwa software. Ibipimo byitwa DMIS, bigereranya ibipimo ngenderwaho bisanzwe. Mugihe atari interineti nyamukuru ya software kuri buri mwana wa CMM, benshi muribo byibuze barayishyigikira.

Abakora bashizeho uburyohe bwabo bwite kugirango bongere imirimo yo gupima idashyigikiwe na DMIS.

Dmis

Nkuko DMIS yavuze, ariko nka G-Kode ya CNC, hari imvugo nyinshi zirimo:

• PC-DMIS: verisiyo ya hexagon
• Gufungura
• Touchmis: Sogorptron

Mcosmos

MCOSTMOS ni porogaramu ya Cmm ya Nikon.

Calypso

Calypso ni Cmm software ya zesi.

Cmm na cad / cam software

Nigute Cmm na porogaramu ifitanye isano na cad / cam software?

Hano haribintu byinshi bya dosiye ya CAD, rero reba kuri software yawe ya CMM ihuye nabyo. Kwishyira hamwe kwanyuma byitwa Model Bishingiye (MBD). Hamwe na MBD, icyitegererezo ubwacyo kirashobora gukoreshwa mugukuramo ibipimo bya CMM.

MDB irutwa neza, ntabwo rero ikoreshwa muburyo bwinshi.

Cmm Ibikorwa, Ibikoresho, nibikoresho

Cmm Ibikorwa

Ubwoko butandukanye bwa probe nuburyo burahari kugirango byorohereze ibintu byinshi bitandukanye.

Cmm

Ibikoresho byose bizigama igihe cyo gupakira no gupakurura ibice kuri cmm, kimwe na mashini ya CNC. Urashobora no kubona Cmm ufite pallet yikora pallet kugirango winjire cyane.

Cmm Igiciro

Imashini nshya yo gupima ipima itangira mumadorari 20.000 kugeza 30,000 hanyuma uzamuke ugera kuri miliyoni zirenga 1.
