Chero ani zvake akawana michina yekuyera chaiyo pasi rese akasangana nedambudziko rimwe chete: chigadzirwa chimwe chete chinogona kutsanangurwa zvichienderana nemiyero mishanu yakasiyana yenyika, imwe neimwe iine sisitimu yayo yekuyera, tafura yekutsungirira, uye mazwi. Kunzwisisa zvinorehwa nemiyero iyi - pane kuitora sezvitambi zvemvumo zvinochinjika - kunokosha kune chero ani zvake anotenga kana kugadzira mapuratifomu epamusoro, matinji akatwasuka, kana maturusi ekuyera granite.
Mitemo Mikuru Pakutarisisa
DIN (Germany) — DIN 876 inosanganisira kushivirira kupfava kwemahwendefa epamusoromuzvikamu zvitatu (00, 0, uye 1), Giredhi 00 rakachengeterwa kushandiswa murabhoritari. DIN 875 inotarisa ma straightedges, uye DIN 650 inovhara maV-blocks. Mitemo yeGerman inoshandiswa zvakanyanya senzvimbo yekutarisa muEurope neAsia nekuda kwematafura avo akadzama ekutsungirira akabatana nehukuru hweplate.
ASME/GGGP (United States) — Nyanzvi yeUS yaimbove ichitsanangura Federal Specification GGG-P-463c, yakazopetwa kuita zviyero zveASME B89, izvo zvinoronga mapuratifomu epamusoro neLaboratory, Inspection, uye Tool grades zvichibva pakusiyana kwenzvimbo.
JIS (Japan) — Maindasitiri eJapan anoratidza chimiro cheDIN asi anoshandisa mazita avo emhando yepamusoro uye nguva dzekuyedza, dzinowanzo taurwa nemidziyo inotumirwa kubva kuindasitiri yezvishandiso zvemuchina weJapan.
GB (China) — Mitemo yenyika yeChina yemapureti epamusoro egranite nezvishandiso zvekuyera zvakabatana zvakanyanya nemaitiro eISO neDIN mumakumi maviri emakore apfuura, zvichiratidza kukura kuri kuita huwandu hwekugadzira zvinhu nemazvo munyika.
BS 817 (United Kingdom) neGOST 10905 (Russia) — Dzese dzinotsanangura zvinodiwa zvakafanana zvekusatsetseka uye kupedzisa pamusoro, neBS 817 yaimbotaurwa nezvayo mumisika yeCommonwealth uye GOST ichiri kutsanangurwa mukutenga kweRussia neCIS.
Nei Kusiyana Kwacho Kuchikosha Mukuita
Dambudziko guru harisi rekuti imwe chiyero "chiri nani" pane chimwe - ndechekuti magiredhi ekushivirira haachinjiki zvakananga nguva dzose. Plate yeGiredhi 0 pasi peDIN 876 uye plate yeLaboratory-grade pasi peASME B89 zvakafanana mupfungwa asi zvakaedzwa pasi penzira dzakasiyana uye mamiriro ekunze (kazhinji tembiricha ye20°C, kunyangwe kushivirira kwekutsauka kuchisiyana). Vatengi vanofunga kuenzana vasina kutarisa mushumo chaiwo wekuyedza vanogona kuguma vaine michina inoenderana nechiratidzo chemwe nyika asi kwete kushivirira kwavanoda.
Kutevedzana Ndiyo Mubvunzo Wechokwadi
Pamusoro pekuti ndechipi chiyero chakadhindwa pachitupa, mubvunzo unonyanya kukosha ndewekuti: kurongeka kunogona kurondwa kuburikidza nesangano renyika remetrology here? Vagadziri vane mukurumbira vanogadzirisa zvishandiso zvavo zvekuyera - zviratidzo zvekuyeresa, mainterferometer elaser, mazinga emagetsi - zvichienderana nezvitupa zvinopihwa nemasangano akavimbika (muChina, kazhinji masangano emetrology emaguta nemapurovhinzi, ane nzira yekudzokera kuNational Institute of Metrology). Pasina cheni iyoyo, chitambi che "Giredhi 0" chinongovimbika chete serabhoritari yakachipa.
Kune mainjiniya anotsanangura mabhesi egranite kana maturusi ekuyera kubva kune vatengesi vepasi rese, chidzidzo chinoshanda chiri nyore: bvunza kuti ndeipi nzira yekuyedza yakashandiswa, kumbira data rekuyera chaiyo kwete kungonyora giredhi chete, uye simbisa kuti michina yekuyedza pachayo ine chitupa chinoteverwa. Vagadziri vanodzidzisa vashandi kuburikidza nemazinga akasiyana-siyana enyika - DIN, ASME, JIS, GB, BS, uye GOST zvakafanana - vanowanzo kuve munzvimbo iri nani yekugadzira zvinhu zvinogara pasi pechero chiyero chinodiwa nesystem yemhando yemutengi.
