Mu mashami agenzura ubuziranenge hirya no hino ku isi, imashini ipima (CMM) ifite umwanya w’ubuyobozi. Iyo igice cy’indege gikozwe mu mashini kigomba kwemezwa hakurikijwe imiterere yacyo, iyo ibikoresho by’ubuhanga bigomba gusuzumwa mbere yo guteranywa, iyo icyuma gishyirwa mu buvuzi gikeneye icyemezo cy’ingano mbere yo gukoreshwa mu kubaga - CMM ni yo isanzwe ifata umwanzuro wa nyuma. Ibipimo byayo bifite uburemere bw’icyizere mu bya tekiniki bugira ingaruka ku byemezo bigira ingaruka ku mutekano, imikorere, n’inshingano z’ubucuruzi.
Nyamara ku bikoresho byose by’ikoranabuhanga bigezweho, ibipimo by’ubuhanga, na porogaramu zigoye zigize CMM igezweho, ishingiro ry’ubuhanga bw’imashini ni ibuye. Gusobanukirwa impamvu - no gusobanukirwa ibiba iyo iryo buye ridafite ubuziranenge buhagije - bihishura ikintu cy’ingenzi ku buryo ubuziranenge bwo gupima bugerwaho mu buryo bufatika.
Icyo CMM ipima n'uko ikora
Imashini ipima ibintu bihuza ibintu ipima ibintu bihuza ingingo z’ibice bitatu ku kintu gifatika. Ibi ibikora ihuza icyuma gipima ibintu kigera ku gice gipimwe (cyangwa hafi yacyo, mu gihe hari ibikoresho bidahuza ibintu) ku buso bw’igice gipimwe, ikandika aho XYZ iherereye kuri buri gice gihuza ibintu, kandi ikabara imiterere ya geometrike (indege, silindiri, utubumbe, ubuso budafite imiterere) buhuye neza n’igicu gipima ibintu.
Ubunyangamugayo bw'iyi gahunda bushingira ku bintu byinshi bikora hamwe nk'uburyo:
- Ubuhanga bw'imirongo itatu y'imashini (uburyo igenda neza mu mirongo igororotse, n'uburyo imyanya yayo ipimwa neza hakoreshejwe imirongo igenamiterere)
- Ubunyangamugayo n'uburyo bwo gusubiramo kwa sisitemu ya probe (uburyo ihora itera aho igera n'uburyo itandukaniye neza n'aho igera ku gice cyo gusoma cya scale)
- Ubushyuhe bw'imiterere y'imashini (kugira ngo hirindwe kwaguka gutandukanye hagati y'ibice bitandukanye)
- Ubwiza bw'ubuso bw'ifatizo rya datum (ubuso burambuye aho ibipimo byose bya Z-axis bikomoka kandi aho imiterere y'imashini ishingira)
Iki kintu cya nyuma — ubuso bw’aho CMM iherereye — ni plaque y’ubuso bwa granite aho CMM yubatswe. Mu bishushanyo byinshi bya CMM, plaque y’ubuso bwa granite si ameza idakora gusa aho imashini ikorera. Ni igice cy’imikorere cy’uburyo bwo gupima. Inkomoko ya CMM ya Z-axis iragaragazwa ugereranije n’ubu buso; inzira ziyobora imigozi itambitse y’imashini zishyirwaho kandi zigakura ubuziranenge bwazo kuri ubu buso; igice gipimirwa gihagaze kuri ubu buso (cyangwa ku gikoresho gishyizwe kuri bwo). Ikosa iryo ari ryo ryose mu kugorofa cyangwa ku guhagarara kw’igihe kirekire kw’plaque ya granite rikwirakwira mu buryo butaziguye mu miyoboro CMM ivuga.
Isahani y'ubuso bwa Granite nka Datum Zero
Muri metrologiya ya kera, datum ni ikintu gishingiye ku buryo bufatika (ingingo, umurongo, cyangwa urwego) aho ibipimo bifatwa. Mu isi ifatika ya CMM, datum plane ni ubuso bwo hejuru bw'ikibaho cy'ubuso bwa granite.
Iyo uruganda rwa CMM rupima imashini nshya, rukoresha ubuso bw'ameza ya granite nk'icyitegererezo cyo gushyiraho sisitemu y'imbere y'imashini. By'umwihariko:
- Ubuso bw'imbonerahamwe bugaragaza imiterere ya XY ya sisitemu yo guhuza imashini
- Ikiraro cya CMM cyangwa umurongo ugororotse (Z) byerekezwa kuri iki gitero
- Ubugororangingo bw'imirongo itambitse (X na Y) bupimwa kandi bugasubizwa ugereranyije n'imiterere nyayo y'ubuso bw'ameza
Uku gupima kubikwa nk'imbonerahamwe y'ubwishingizi bw'imiterere y'imashini mu igenzura rya CMM. Iyo imashini ipima igice, izi ngengo y'imari zibitswe zikosora amakosa yakozwe mu buryo busanzwe mu migendekere y'imashini - amakosa yapimwe kandi agaragazwa ugereranyije n'ubuso bwa granite igihe cyo gupima.
Iyo icyuma gishushanyijeho granite gihinduye imiterere — bitewe no kwangirika, ubushyuhe, cyangwa kugabanya imbaraga z’imbere — imbonerahamwe y’ubwishingizi ntabwo ikomeza gusobanura neza imiterere y’imashini. CMM isa nkaho ikora neza (igenda, icyuma gitera, ibipimo biratangazwa) ariko ibipimo birimo amakosa ari mu buryo bwikora yiyongera uko imiterere y’icyuma gishushanyije igenda igabanuka. Ayo makosa ni ay’uburiganya cyane kuko atari ay’uburiganya — afitanye isano mu buryo bw’ahantu, agaragara nk’ibice by’imbonerahamwe aho amakosa y’imiterere yagaragaye.
Amanota yo guhitamo porogaramu za CMM
Ntabwo buri porogaramu ya CMM isaba amanota amwe yaisahani yo hejuru ya granite, ariko guhitamo bigomba gushingira ku bisabwa mu gupima ibintu bidasobanutse neza, ntabwo ari igiciro cyo kugura cy’imbonerahamwe.
CMM na Laboratwari zo Gupima
CMM zikoreshwa nk'imashini zigenzura - zipima izindi CMM, zemeza ibikoresho by'ubushakashatsi, cyangwa zikora nk'umuyoboro w'ubugenzuzi ku buryo bwo gupima - ubusanzwe zikenera urwego rwa 00 (urwego rwa laboratwari kuri DIN 876) cyangwa Laboratwari y'urwego kuri ASME B89.3.7. Izi ni plaque zo hejuru cyane zikorerwa mu bucuruzi, zifite ubushobozi bwo kwihanganira ubugari buri hasi mu rugero rwo hasi rwa mikorometero imwe hejuru y'ubuso bwose bw'ameza.
Kuri uru rwego, ubuso bw'ameza ya granite bugomba kandi kongera kwemezwa buri gihe no kwemezwa bundi bushya, ibipimo bigakurikiranwa n'ibipimo by'igihugu. Igihe cyo kongera kwemezwa giterwa n'ubukana bw'ikoreshwa n'uburemere bw'ibipimo, ariko ubusanzwe biba buri mwaka cyangwa kabiri mu mwaka.
Igenzura ry'ibicuruzwa ku nyubako za CMM
CMM zikoreshwa mu igenzura ry’umusaruro — zigenzura ko ibice byakozwe mu mashini byujuje ibisabwa mbere yo guteranya — akenshi zikora n’ibipande by’ubuso bya grade 0 cyangwa grade 1. Ibisabwa mu gupima ibintu bidasobanutse neza mu igenzura ry’umusaruro biraruhura kurusha mu kazi ko gupima, kandi mu buryo nk’ubwo, ibisabwa ku meza ya granite ntibigoye cyane.
Ariko, "guterura cyane" bigomba kumvikana mu rwego rwo kugenzura ubushobozi bw'ibice. Niba CMM ikoreshwa mu kugenzura imiterere ifite ubushobozi bwa μm 10–20, icyuma cyo hejuru cya 1 (gifite ubugari buri hagati ya μm 5–10 ugereranyije n'ameza angana neza) birakwiye. Gukoresha icyuma cyo hejuru cya 2 cyangwa icyuma cyo hejuru cya workshop kuri iyi porogaramu bishobora gutuma ikosa ry'imiterere y'ameza rigira uruhare runini mu gupima gukomeye.
CMM ntoya z'ibikoresho by'ikoranabuhanga na optique nziza
Mu ishami rikora ibikoresho by'ikoranabuhanga n'ikoranabuhanga rigezweho, CMM nto zikoreshwa mu gupima imiterere ku rwego rwa micrometer na sub-micrometer ku bice nk'aho bihurira, aho bashyira amashusho, n'ibikoresho bya kamera bikozwe mu buryo bugezweho. Izi porogaramu zisaba plaque zo hejuru za 00 - kandi, rimwe na rimwe, ameza ya granite agenzurwa n'ubushyuhe - kugira ngo hagerwe ku bintu bidasobanutse neza bikenewe mu gupima.
Uburyo Busanzwe bwo Kunanirwa: Ni iki Kitagenda neza Iyo Ubuziranenge bwa Granite Budahagije
Ingaruka zo kugaragaza cyangwa kwakira granite nziza idahagije muri CMM zigaragara mu buryo butandukanye bwo gucika intege:
Uburyo bwo gusohora amakuru mu buryo busanzwe mu bice bikoreshwa cyane
Hagati mu mbonerahamwe ya CMM, n'uturere turi munsi y'aho ibikoresho bikunze gukoreshwa, bihura n'ubucucike bwinshi bw'aho ibikoresho bihurira n'aho bishyirwa hamwe ndetse n'umubare munini w'ibice bishyirwamo. Uko igihe kigenda gihita, utu duce dushobora kwangirika, bigatuma habaho gufungana gato. Ameza ya granite yo mu rwego rwa 0 cyangwa 00 yakozwe neza, yakozwe mu bikoresho bikomeye kandi bikomeye, irwanya kwangirika neza. Ibuye ryizewe nabi - cyane cyane marble cyangwa granite y'imvi nke - ni ryoroshye cyane kandi ritera imiterere yo kwangirika vuba.
Mu bikorerwamo aho ahantu runaka hakoreshwa inshuro ibihumbi mu kwezi, uku kwambara gushobora kwiyongera kugeza aho bigira ingaruka ku buryo ibipimo bipima neza mu gihe cy'umwaka umwe cyangwa ibiri. Ibimenyetso bigaragara nk'ubwiyongere bwiza cyangwa bubi mu gice cya Z gipimirwa aho cyashaje - ubwiyongere bushobora kutamenyekana ako kanya nk'ikibazo cyo kwambara ku meza.
Ubushyuhe buhindagurika buturutse ku gice cyo hasi
Ameza ya granite ya CMM mu bikorwa bikorerwamo akenshi ashyirwa ku igorofa ry’uruganda rihura n’ubushyuhe bwinshi - cyane cyane hafi y’inkuta zo hanze, inzugi z’aho bapakira ibikoresho, cyangwa hafi y’ibikoresho bitanga ubushyuhe. Iyo ameza ya granite ihuye cyane n’ubutaka butari bumwe, ubushyuhe bunyura mu meza butangana, bigatuma ubushyuhe buhinduka bugahindura ubuso bw’ameza.
Granite nini cyane (nk'umukara ufite ubucucike bwinshi) ifite ubushobozi bwo gutwara ubushyuhe buke kandi CTE nkeya kurusha granite isanzwe y'ikijuju, bivuze ko ihangana buhoro n'ibibazo by'ubushyuhe kandi ikagoreka gake iyo hari ubushyuhe buke. Igihe cy'ubushyuhe cy'ameza manini kandi akomeye ni kirekire - bifata amasaha menshi kugira ngo ingaruka zuzuye z'ubushyuhe zigaragare - ariko iyo ubushyuhe bumaze kugaragara, bukomeza igihe kirekire nk'icyo nyuma y'uko isoko y'ubushyuhe ikuweho.
Uburyo busanzwe bwo kugabanya ubushyuhe ni ugutandukanya neza ameza ya granite ya CMM n’ubutaka — hakoreshejwe ibikoresho byo gukingira bitanga ubushyuhe — no gushyira CMM ahantu hadahinduka n’ubushyuhe kure y’amasoko y’ubushyuhe n’inkuta zo hanze.
Gutembera no kuruhuka mu ibuye ritarashaje bihagije
Granite itarashaje neza kandi itaragabanya stress mbere yo gukora neza ishobora gukomeza kuruhuka buhoro buhoro nyuma yo gutanga, bigatuma ubuso bwakozwe buva mu ishusho yabwo mu mezi menshi. Ubusanzwe iyi nzira igenda buhoro kandi itanga umuvuduko wo kumanuka uri munsi ya mikorometero imwe ku mwaka mu bikoresho byatunganyijwe neza - ariko mu rwego rwo kugenzura ibisabwa na CMM, ndetse n'iyi mivuduko yo kumanuka buhoro ni ingenzi mu gihe cy'imyaka myinshi ibikoresho by'ubuhanga bimara.
Umuti ukwiye ni ugusuzuma neza ibikoresho bishya bitangwa n’uruganda rukora plaque, harimo no gusaza igihe gito ku bikoresho biciwe mbere yuko bitangira gutunganywa neza. Uruganda rurenga iyi ntambwe kugira ngo rugabanye igihe cyo gukora rugurisha ibicuruzwa bisa n’aho byujuje ibisabwa mu gihe cyo kubitanga ariko bikagabanuka mu gihe cyo kubitanga.
Gutunganya Ameza ya Granite ya CMM biri mu mirimo
Kimwe n'ibikoresho byose byo gupima neza, amasafuriya y'ubuso bwa granite ya CMM akeneye gusanwa buri gihe no kongera gupimwa kugira ngo harebwe ko akomeje kugera ku bugari bwayo. Uburyo bwiza bwo kubungabunga ameza ya granite ya CMM burimo:
Gukurikirana ubushyuhe n'inyandiko — Kubika urutonde rw'ibipimo by'ubushyuhe mu mbonerahamwe bigaragaza imiterere y'ubushyuhe kandi bigafasha guhuza ibitagenda neza mu gupima n'ibihe by'ubushyuhe.
Gusukura buri gihe — Ubuso bugomba gusukurwa buri gihe hakoreshejwe imashini zisukura zabugenewe (pH idasembuye, idasembuye) kugira ngo ukureho uduce duto, ibisigazwa by'udukoko dukonjesha, n'uduce duto dushobora kwangiza ubuso. Ubuso ntibugomba na rimwe gusukurwa n'ibikoresho bisembuye.
Kongera kugenzura ubugari bw'igipimo - Ubugari bw'igipimo bugomba gupimwa ukurikije icyemezo cy'umwimerere kugira ngo hamenyekane uko ibintu bigenda cyangwa byangirika. Uburyo bwo gupima n'igikoresho bigomba kwandikwa kandi bigakurikiranwa hakurikijwe ibipimo bimwe n'icyemezo cy'umwimerere.
Gufata neza ibikoresho biremereye — Ibikoresho biremereye cyangwa ibice bigomba gushyirwa ku buso bwa granite witonze kandi bigashyigikirwa ahantu hangana kugira ngo hirindwe ko hari ahantu hashobora gukurura ibintu bishobora gukata impande cyangwa bigatera stress nyinshi aho hantu.
Gusana imashini zicagagura n'ibyangiritse — Imashini n'ahantu hangiritse bigomba kwandikwa no gusuzumwa. Imashini nto mu bice bitari ingenzi zishobora kutagira ingaruka ku buryo imashini ikora neza iyo ziri hanze y'aho imashini ikorera. Imashini zicagagura mu bice bipimirwa cyane zigomba gusuzumwa hakurikijwe ingengo y'imari y'imashini kugira ngo hamenyekane niba kongera gukoresha imashini cyangwa kuyisimbuza ari ngombwa.
Imbonerahamwe ya Granite nk'igice cy'ingengo y'imari idafite ishingiro yo gupima
ISO 10360, igipimo mpuzamahanga kigenga isuzuma ry’imikorere ya CMM, kigaragaza uburyo ukuri kw’ibipimo bya CMM bigomba kugenwa no kugaragazwa. Igipimo gitandukanya ukuri kw’ibipimo bya CMM n’uburyo ibipimo byose bidasobanutse neza bikoreshwa ku gikorwa runaka cyo gupima.
Uburyo bwose bwo gupima butari bwo kugena uko CMM ipima burimo uruhare ruturutse kuri:
- Ubuziranenge bw'ingano ya CMM (kuva ku isuzuma rya ISO 10360)
- Amakosa yo gupima isuzuma
- Ingaruka zo gufunga ibice no gufunga
- Ingaruka z'ubushyuhe ku gice no ku mashini
- Ikosa ry'imiterere y'ubuso bw'ameza ya granite
Iyi nkunga ya nyuma - ikosa ry'imiterere y'imbonerahamwe ya granite - ikunze gukurwa mu isesengura ryoroheje ry'ibidashoboka, cyane cyane mu bidukikije aho kwibanda ku gihe cy'izunguruka rya buri gice aho kuba isesengura ry'ibidashoboka. Kubireka bitera ibipimo bitazwi neza kandi bitanga icyizere; ibisubizo nyabyo by'ibipimo birimo ikindi gice cy'ikosa kitaramenyekana.
Ingengo y'imari yuzuye kandi ihamye yo gupima - nk'uko bisabwa na ISO/IEC 17025 ku ma laboratwari yemewe yo gupima, ndetse no kuba inzobere mu gupima ibintu by'ingenzi - igomba kuba irimo uruhare rw'ubuso bw'ameza ya granite. Ibi bisaba kumenya ubugari bw'ameza nyabwo (kuva ku isuzuma riheruka), no kumenya uburyo iryo kosa ry'ubugari rijyanye n'ibipimo biri gukorwa.
Umwanzuro: Imiterere y'ibintu byose bishingiyeho
CMM ni sisitemu yo gupima, kandi kimwe na sisitemu zose zo gupima, ubunyangamugayo bwayo bugengwa n'ubunyangamugayo bw'aho igarukira. Isahani y'ubuso bwa granite ni yo referensi - ku murongo wa Z, ku ndege ya XY, ku gupima ibice, no ku gupima ikarita yose y'amakosa ya geometrike y'imashini.
