Ibigomba kwitabwaho mu guhitamo
Mu guhitamo urubuga rwa granite, ugomba gukurikiza amahame yo "guhuza neza porogaramu, ingano ihuye n'aho ikorerwa, no kwemeza ko iyubahirizwa." Ibi bikurikira bisobanura ibipimo by'ingenzi byo guhitamo uhereye ku ngingo eshatu z'ingenzi:
Urwego rw'Uburyo: Guhuza imiterere yihariye y'amasomo n'amahugurwa
Urwego rw'ubuziranenge butandukanye ruhura n'ibihe bitandukanye byo gukoresha, kandi guhitamo bigomba gushingira ku bisabwa mu buryo bunoze bw'aho imikorere ibera:
Laboratwari/Ibyumba byo kugenzura ubuziranenge: Amanota asabwa ni Class 00 (imikorere ijyanye n'ubuziranenge) cyangwa Class AA (ubuziranenge bwa mm 0.005). Ibi bikwiranye n'ikoreshwa rya ultra-precision nko gupima ubuziranenge no kugenzura optique, nk'amabara akoreshwa mu mashini zipima (CMMs).
Ahakorerwa imirimo/Ahakorerwa imirimo: Guhitamo Icyiciro cya 0 cyangwa Icyiciro cya B (ubuziranenge bwa mm 0.025) bishobora guhaza igenzura rusange ry'ibikoresho, nko kugenzura ibice bya CNC, mu gihe bipima uburambe n'ikiguzi. Ingano: Kuva ku gipimo gisanzwe kugeza ku gishushanyo mbonera cy'ahantu hifashishijwe ikoranabuhanga
Ingano y'urutonde igomba kuba yujuje ibisabwa haba mu gushyiramo ibikoresho byo gukoreraho ndetse n'ibisabwa mu mwanya wo gukoreraho:
Formula y'ibanze: Ubuso bw'urupapuro bugomba kuba bunini ho 20% ugereranyije n'igice kinini cy'umurimo kirimo gusuzumwa, bigatuma habaho icyuho cy'umupaka. Urugero, kugira ngo ugenzure igice cy'umurimo gifite 500×600 mm, ingano ya 600×720 mm cyangwa irenga ni byiza.
Ingano Zisanzwe: Ingano zisanzwe ziri hagati ya mm 300×200×60 (ntoya) na santimetero 48×96×10 (nini). Ingano zihariye ziri hagati ya mm 400×400 na mm 6000×3000 zirahari ku buryo bwihariye.
Ibikoresho by'inyongera: Hitamo muri T-slots, imyobo ifite imigozi, cyangwa imiterere y'inkombe (nk'urukuta rwa 0 na 4-ledge) kugira ngo wongere ubushobozi bwo gushyiraho ibikoresho.
Icyemezo n'Iyubahirizwa ry'Amategeko: Gutanga Ingwate ku buryo bubiri ku byoherezwa mu mahanga no ku bwiza
Icyemezo cy'ingenzi: Kohereza ibicuruzwa mu mahanga ku masoko y'i Burayi na Amerika bisaba abatanga ibicuruzwa gutanga icyemezo cya ISO 17025 kirekire, harimo amakuru yo gupima, kutamenya neza, n'ibindi bipimo by'ingenzi, kugira ngo hirindwe gutinda kwemererwa ibicuruzwa bya gasutamo bitewe n'inyandiko ituzuye. Amahame y'inyongera: Ku bijyanye n'ubuziranenge bw'ibanze, reba amabwiriza nka DIN 876 na JIS kugira ngo urebe ko ubushobozi bwo kwihanganira ibintu (urugero, Grate 00 ± 0.000075 santimetero) n'ubucucike bw'ibikoresho (granite y'umukara ikundwa kubera imiterere yayo ikomeye no kudahinduka) byujuje ibisabwa.
Guhitamo byihuse Irebereho
Gukoresha laboratwari neza cyane: Icyiciro cya 00/AA + 20% biruta igikoresho cyo gukora + icyemezo cya ISO 17025
Isuzumabumenyi risanzwe: Icyiciro cya 0/B + ingano zisanzwe (urugero, santimetero 48 × 60) + kubahiriza DIN / JIS
Kohereza ibicuruzwa mu Burayi no muri Leta Zunze Ubumwe za Amerika: Icyemezo kirekire cya ISO 17025 ni itegeko kugira ngo hirindwe ingaruka zo kwemererwa ibicuruzwa muri gasutamo.
Binyuze mu guhuza neza, kubara mu buryo bwa siyansi, no kugenzura no kwemeza neza, twemeza ko urubuga rwa granite rwujuje ibisabwa mu musaruro ndetse n'amahame mpuzamahanga agenga imitunganyirize y'ibicuruzwa.
Inama ku bijyanye no kubungabunga no gupima
Imikorere myiza y’urukuta rwa granite ishingiye ku buryo bwa siyansi bwo kubungabunga no gupima. Ibi bikurikira bitanga ubuyobozi bw’umwuga mu buryo butatu: ikoreshwa rya buri munsi, kubika igihe kirekire, no kwemeza neza ko ibintu bipimwe bikomeza kuba inyangamugayo.
Kubungabunga buri munsi: Isuku n'Uburinzi Ingingo z'ingenzi
Uburyo bwo gusukura ni bwo shingiro ryo kubungabunga ubuziranenge. Mbere yo gukoresha, menya neza ko ubuso nta bizinga. Turakugira inama yo guhanagura n'amazi 50% na 50% bya arukoro ya isopropyl. Kumutsa n'igitambaro cyoroshye cyangwa igitambaro cy'impapuro kugira ngo wirinde kwangiza ubuso bwa granite ukoresheje isuku ivanze n'aside cyangwa ibikoresho byo gukaraba. Mbere yo gushyira ibice, kuraho buhoro buhoro ukoresheje amabuye kugira ngo ukureho uduce duto cyangwa impande zityaye. Siga amabuye hamwe mbere yo kuyakoresha kugira ngo usukure urubuga kugira ngo wirinde ko umwanda uhasya. Icy'ingenzi: Nta mavuta akenewe, kuko agahu k'amavuta kazagira ingaruka ku buryo butaziguye ku buziranenge bw'ibipimo.
Imiterere y'ibikorwa byo kubungabunga buri munsi
Ntugakoreshe isuku irimo ammonia nka Windex (ishobora kwangiza ubuso).
Irinde gukubita ibintu biremereye cyangwa gukurura ibintu mu buryo butaziguye ukoresheje ibikoresho by'icyuma.
Nyuma yo gusukura, menya neza ko wumisha neza kugira ngo wirinde ko amazi asigara.
Kubika igihe kirekire: Kurwanya kwangirika no gukumira ivumbi
Iyo udakoreshwa, fata ingamba ebyiri zo kwirinda: Turakugira inama yo gupfuka hejuru ukoresheje plywood ya santimetero 1/8-1/2 iriho icyuma cyangwa umupira, cyangwa igipfundikizo cy'umukungugu cyabugenewe, kugira ngo utandukanye n'umukungugu n'udusimba duto. Uburyo bwo gushyigikira bugomba kubahiriza amabwiriza ya leta GGG-P-463C, hakoreshejwe ingingo eshatu zihamye hepfo kugira ngo urebe ko imizigo ikwirakwira neza kandi ugabanye ibyago byo kwangirika kw'amazi. Ingingo zo gushyigikira zigomba guhuza n'ibimenyetso biri hepfo y'urukuta.
Ingwate y'ukuri: Igihe cyo gupima no kwemeza
Gupima buri mwaka birasabwa kugira ngo hamenyekane neza ko ikosa ry’ubugari bw’aho ibintu biherereye rikomeza kuba rijyanye n’ibipimo bya mbere. Gupima bigomba gukorwa ahantu hagenzurwa ku bushyuhe buhoraho bwa 20°C n’ubushuhe kugira ngo hirindwe ubushyuhe cyangwa umwuka ushobora kubangamira ibisubizo by’ibipimo.
Ku bijyanye n’impamyabushobozi, porogaramu zose ziza zifite icyemezo cyo gupima gikurikiranwa hakurikijwe amabwiriza mpuzamahanga ya NIST cyangwa ibipimo ngenderwaho bingana nayo, bihamya ko bizakomeza kuba birebire kandi bisubirwamo. Ku bijyanye n’ibikorwa byo mu kirere bigezweho, serivisi zo gupima za ISO 17025 zemewe na UKAS/ANAB zishobora gusabwa, bikongera iyubahirizwa ry’ubuziranenge binyuze mu kwemezwa n’abandi bantu.
Inama zo Gupima
Mbere yo gukoresha bwa mbere, banza urebe neza niba icyemezo cyo gupima gihari.
Gusubiramo ikoreshwa birakenewe nyuma yo kongera gusya cyangwa gukoresha mu murima (hakurikijwe ASME B89.3.7).
Ni byiza gukoresha uwakoze ikoranabuhanga rya mbere cyangwa umutanga serivisi wemewe kugira ngo agenzurwe neza kugira ngo hirindwe ko ibintu bidahinduka burundu bitewe n’imikorere idahwitse.
Izi ngamba zemeza ko urubuga rwa granite rugumana ubuziranenge bwo gupima ibintu mu gihe cy’imyaka irenga 10, bitanga uburyo buhoraho kandi bwizewe bwo gukoresha nko kugenzura ibice by’indege no gukora ibumba neza.
