6,umucuukulinganisa

Ngomucu ojwayelekile ojwayelekile, igeji yokukala indandatho yochungechunge noma igeji yepulaki isetshenziselwa ukukala.

Ngenxa yokuthi ipharamitha yentambo miningi, akunakwenzeka ukukala ipharamitha ngayinye yochungechunge ngalunye, ngokuvamile sisebenzisa igeji yentambo (igeji yokukala indandatho yochungechunge, igeji yepulaki yentambo) ukuze sahlulele intambo ngokugcwele.Lolu hlobo lwezindlela zokuhlola lungokwendlela yokuhlola yokwamukelwa yohlobo lokuhlanganiswa kwe-analogi, hhayi nje elula, enokwethenjelwa, futhi imfuneko enembayo enentambo evamile impela, ngoba lena sekuyiyona ndlela evamile yokuhlola ukwamukelwa esetshenziswa ekukhiqizeni kwangempela okwamanje.

7, ukulinganisa kwentambo (ububanzi obuphakathi)

Ekuxhumekeni kwentambo, ubukhulu be-diameter obuphakathi kuphela obunquma ubunjalo bokulingana kwentambo, ngakho-ke indlela yokwahlulela kahle ukuthi ububanzi obuphakathi bufanelekile kubaluleke kakhulu.Ngokusekelwe eqinisweni lokuthi usayizi wedayamitha emaphakathi kufanele uqinisekise ukuthi ukusebenza kwesevisi okuyisisekelo kakhulu kochungechunge kuyafinyelelwa, umbandela wokufaneleka kobubanzi obumaphakathi ucaciswe ezingeni: “Ububanzi obumaphakathi bomucu wangempela akufanele budlule ububanzi obumaphakathi bephrofayili yezinyo eliqinile elikhulu kunawo wonke.Ububanzi obubodwa obumaphakathi banoma iyiphi ingxenye yomucu wangempela akufanele budlule ububanzi obumaphakathi bomumo wezinyo eliqinile elincane kunawo wonke.”

I-Single diameter yokukala indlela elula kakhulu inezinhlobo ezimbili njengamanje, eyodwa iwukusebenzisa intambo yobubanzi be-micrometer ukukala ububanzi, enye iwukusebenzisa isilinganiso senaliti ezintathu (engisebenzise isilinganiso senaliti ezintathu).

8. Ibanga lokufanisa intambo:

Ukulingana kwentambo kuwusayizi oxegayo noma oqinile phakathi kwemicu eyisikulufa, futhi izinga lokulingana liyinhlanganisela ecacisiwe yokuchezuka nokubekezelelana okusetshenziswa emicu yangaphakathi neyangaphandle.

(1) Emiculweni eyi-intshi efanayo, kunamabanga amathathu entambo: 1A, 2A kanye no-3A kuntambo yangaphandle, namabanga amathathu: 1B, 2B kanye no-3B ngentambo yangaphakathi, wonke alingana negebe.Uma iphezulu inombolo yebanga, kuqina ukulingana.Kuchungechunge lwamayintshi, ukuchezuka kucaciswe ebangeni 1A no-2A kuphela, ibanga 3A linguziro, futhi ibanga 1A no-2A liyalingana.

Uma inani lamabanga likhulu, liba lincane ukubekezelelana, njengoba kuboniswe emfanekisweni:

I-1) I-Class 1A ne-1B, isigaba sokubekezelelana esixege kakhulu, esilungele ukubekezelela ukulingana kwemicu yangaphakathi neyangaphandle.
2) Ikilasi 2A kanye ne-2B amakilasi avame kakhulu okubekezelela intambo acaciswe ochungechungeni lwaseBrithani lwezibopheli zemishini.
3) I-Class 3A ne-3B, isikulufu ukuze senze ukulingana okuqinile, okufanelekile izibophelelo ezinokubekezelelana okuqinile, ngomklamo oyinhloko wokuphepha.
4) Emicu yangaphandle, kukhona ukuchezuka okufanele kwekilasi 1A no-2A, kodwa hhayi kwekilasi 3A.Ukubekezelelana kwekilasi 1A kukhulu ngo-50% kunokubekezelelana kwekilasi 2A, 75% kukhulu kunokubekezelelana kwekilasi 3A kanye no-30% kukhulu kunokubekezelelana kwekilasi 2B emicu yangaphakathi.I-1B ingamaphesenti angu-50 mkhulu kuno-2B futhi 75 amaphesenti amakhulu kuno-3B.

(2)intambo yemethrikhi, intambo yangaphandle inebanga elivamile lentambo: 4H, 6E, 6g kanye ne-6H, intambo yangaphakathi inebanga elivamile lentambo: 6g, 6H, 7H.(Ibanga lokunemba kwentambo yesikulufu yansuku zonke ihlukaniswe ngo-I, II, III, ngokuvamile II) kuchungechunge lwemethrikhi, ukuchezuka okuyisisekelo kuka-H no-H kunguziro.Ukuchezuka okuyisisekelo kuka-G kuphozithivu, futhi lokho kuka-E, F, kanye no-G kunegethivu.Njengoba kuboniswe emfanekisweni:

I-1) H indawo evamile yokubekezelela indawo emicu yangaphakathi, futhi ngokuvamile ayisetshenziswa njengendawo yokumboza, noma ngongqimba oluncane lwephosphating.Ukuchezuka okuyisisekelo kokuma kwe-G kusetshenziselwa izikhathi ezikhethekile, njengokucweba, futhi akuvamile ukusetshenziswa.

2) I-G ijwayele ukusetshenziselwa ukunamathelisa okungu-6-9um okuncanyana, okufana namabhawudi angu-6h adingwa imidwebo yomkhiqizo, intambo ngaphambi kokucwecwa izothatha ibhendi yokubekezelela engu-6g.

3) Ukulingana kwentambo kungcono kakhulu kuhlanganiswe ku-H/ G, H/ H noma G/H, kumabhawudi, amantongomane neminye imicu yokubopha ecolisisiwe, ukulingana okujwayelekile okunconyiwe okungu-6H/6g.

Izinga elimaphakathi lokunemba lochungechunge oluvamile
Inathi: 6H ibhawudi: 6g
Ibanga elimaphakathi lokunemba kochungechunge olunomthwalo osindayo
Inathi: 6G Bolt: 6E
Izinga eliphezulu lokunemba
Inathi: 4H Bolt: 4H, 6h

9, intambo ekhethekile evamile
