Kuyini ukubekezelelana kwejometri

I-ISO ichaza ukubekezelelwa kwejiyomethri njengokuthi "Ukucaciswa komkhiqizo weJiyomethri (GPS)−Ukubekezelela kweJomethrikhi−Ukubekezelela isimo, umumo, indawo kanye nokuphelelwa yisikhathi".Ngamanye amazwi, "izici zejiyomethri" zisho ukuma, usayizi, ubudlelwano bendawo, njll. bento, futhi "ukubekezela" "ukubekezelela iphutha".Isici "sokubekezelelana kwejometri" ukuthi akuchazi nje ubukhulu, kodwa futhi nokubekezelelana kokuma nesimo.

Umehluko phakathi kokubekezelelana kwe-dimensional kanye ne-geometric:

Izindlela zokulebula imidwebo yokuklama zingahlukaniswa kabanzi zibe izigaba ezimbili: "ukubekezelelana kwe-dimensional" kanye "nokubekezelelana kwejometri".Ukubekezelelana kwe-Dimensional kulawula ubude bengxenye ngayinye.

Ukubekezelelana kweJiyomethri kulawula ukuma, ukufana, ukuthambekela, isikhundla, ukuphuma, nokunye.

I-Dimensional Tolerance Umdwebo

Umdwebo wokubekezelela wejometri

Kusho "qinisekisa ukuthi i-surface A ayidluli ukufana kuka-0.02".

Kungani kufanele umake ukubekezelelana kwejometri?

Isibonelo, lapho e-oda ingxenye yepuleti, umklami ucacise ukubekezelela kobukhulu njengoba ngezansi.

A Ibhande lokubekezelelana

Nokho, ngokwemidwebo engenhla, umenzi anganikeza lezi zingxenye.

A Ibhande lokubekezelelana

Izingxenye zingase zingafaneleki noma zibe nesici uma ukufana kungaphawulwanga emdwebeni.

Umkhiqizi akanalo umthwalo wemfanelo, kodwa kunalokho ukumaka ukubekezelela komklami.Imidwebo yengxenye efanayo ephawulwe ukubekezelelwa kwejometri ingaholela ekwakhiweni okuboniswe ngezansi.Ulwazi lokubekezelela iJiyomethri, njengokuthi "i-parallelism" kanye "nokuhlelwa", yengezwa kumfanekiso ngokusekelwe kulwazi lobukhulu.Lokhu kusiza ukugwema izinkinga ezibangelwa ukumane uphawule ukubekezelelana kwe-dimensional.

aUkubekezelelana KokuhambisanabUkubekezelelana kwe-FlatnesscI-Datum

Ukufingqa, ukusebenzisa ukubekezelelana kwejometri kungaveza ngempumelelo futhi ngokushesha lokho umklami akufunayo, okungenzeka kungenzeki ngokubekezelelana kobukhulu.

Incazelo ku-ISO

Ukuxhumana phakathi kosayizi nokuma kuchazwa kanje:

Imininingwane ku-ISO8015-1985eziboniswa kumapulani, njengosayizi nokulinganiselwa komumo, azihambelani nabanye osayizi, imikhawulo, noma izibaluli futhi zisebenza ngokwazo ngaphandle kwalapho kucaciswe ngenye indlela.

Njengoba kushiwo ngaphambili, isimiso sokuzimela siyindinganiso yomhlaba echazwe yi-ISO.Nokho, ezinye izinkampani zase-US zingase zingawulandeli umgomo wokuzimela ngokuhambisana nemihlahlandlela ye-ASME (American Society of Mechanical Engineers).Ukuze ugweme noma yikuphi ukudideka ngesikhathi sohwebo nezinkampani zakwamanye amazwe, kutuswa ukuba kuxoxisane futhi kucaciswe izidingo zokucaciswa kusengaphambili.

I-Xiamen Ruicheng inikeza ukubonisana kwamahhala kwayo yonke imiklamo.Zizwe ukhululekile ukuxhumana nathi nganoma yiziphi izidingo zamazinga okukhiqiza/okuhlola .
