1. Usoro mgbako maka n'ime oghere dayameta nke eri extrusion ọpịpị:
Usoro: dayameta nha nha nha - 1/2 × pitch eze
Ọmụmatụ 1: Ụdị: M3×0.5＝3-(1/2×0.5)＝2.75mm
M6 × 1.0＝6－(1/2×1.0)：5.5mm
Ọmụmatụ 2: Ụdị: M3×0.5＝3-(0.5÷2)＝2.75mm
M6×1.0＝6－(1.0÷2)：5.5mm

2. Usoro ntụgharị maka ọpịpị waya Britain izugbe:
1 inch = 25.4mm (koodu)
Ọmụmaatụ 1: (1/4-30)
1/4×25.4＝6.35( dayameta eze)
25.4÷30＝0.846 (anya eze)
Mgbe ahụ 1 / 4-30 gbanwere n'ime ezé metric kwesịrị ịbụ: M6.35 × 0.846
Ihe atụ 2: (3/16-32)
3/16×25.4＝4.76 ( dayameta eze)
25.4÷32＝0.79 (anya eze)
Mgbe ahụ 3 / 16-32 gbanwere n'ime ezé metric kwesịrị ịbụ: M4.76 × 0.79
3. Usoro izugbe maka ịtụgharị eze Briten ka ọ bụrụ eze metric:
Ọnụọgụgụ ÷ denominator × 25.4 = dayameta eze dị n'elu (nke dị n'elu)
Ọmụmaatụ 1: (3/8-24)
3÷8×25.4＝9.525(eze elu dayameta)
25.4÷241.058 (metric pitch)
Mgbe ahụ 3 / 8-24 ghọrọ metric ezé kwesịrị: M9.525 × 1.058
4. Usoro maka ịtụgharị ezé America ka ọ bụrụ ezé metric:
Ọmụmaatụ: 6-32
6-32 (0.06+0.013)/koodu × 6 0.138
0.138×25.4＝3.505 (mpụta dayameta nke eze)
25.4÷32＝0.635 (ebe eze dị anya)
Mgbe ahụ 6-32 ghọrọ metric ezé kwesịrị: M3.505 × 0.635
1. Usoro mgbako nke oghere dị n'ime dayameta:
Dayameta mpụta nke eze - 1/2 × pitch eze kwesịrị ịbụ:
M3.505 - 1/2 × 0.635 3.19
Mgbe ahụ n'ime dayameta nke 6-32 kwesịrị ịbụ 3.19
2. Extrusion waya imetụ oghere ime oghere algọridim:
Usoro mgbako dị mfe nke dayameta oghere dị ala 1:
Dayameta dị n'elu eze - (nkwụ eze × 0.4250.475)/ koodu = dayameta oghere dị ala
Ọmụmaatụ 1: M6×1.0
M6- (1.0×0.425)=5.575 (oghere kacha ala)
M6-(1.0×0.475)=5.525(kacha nta)
Ọmụmaatụ 2: Usoro ngụkọ dị mfe maka dayameta dị n'ime oghere nke waya ịcha ji metụrụ:
M6 - (1.0×0.85)=5.15 (kachasị)
M6 - (1.0 × 0.95) 5.05 (nke kacha nta)
M6 - (Isi eze × 0.860.96) / koodu = oghere dị ala
Ọmụmaatụ 3: M6×1.0＝6-1.0＝5.0+0.05＝5.05
5. Usoro dị mfe maka ịgbakọ dayameta mpụta nke ezé pịa:
1. Dayameta - 0.01 × 0.645 × pitch (mkpa ịgafe na kwụsị)
Ọmụmaatụ 1: M3×0.5＝3-0.01×0.645×0.5＝2.58 (mpụta dayameta)
Ọmụmaatụ 2: M6 × 1.0＝6-0.1×0.645×1.0＝5.25 ( dayameta mpụta)
6. Usoro mgbako maka metric eze na-atụgharị dayameta: (Ngụkọta nha nha zuru oke)
Ọmụmaatụ 1: M3 × 0.5＝3-0.6495×0.5＝2.68 ( dayameta elu tupu atụgharị)
Ọmụmaatụ 2: M6 × 1.0＝6-0.6495×1.0＝5.35 ( dayameta nke mpụta tupu atụgharị)
7. Embossed elu dayameta omimi (mpụta dayameta)
Dayameta dị n'èzí ÷25.4× pitch eze = Dayameta dị n'èzí tupu a na-eme ya
Ọmụmaatụ: 4.1÷25.4×0.8 (ifuru pitch)=0.13 Omimi embossing kwesịrị ịbụ 0.13
8. Usoro ntụgharị diagonal maka ihe polygonal:
1. Square: dayameta diagonal × 1.414 = dayameta diagonal
2. Pentagon: dayameta diagonal × 1.2361 = dayameta nke dayameta
3. Hexagon: Dayameta nke akụkụ ndị ọzọ × 1.1547 = Dayameta nke akụkụ dị iche
Usoro 2: 1. Nkuku anọ: dayameta diagonal ÷ 0.71 = dayameta diagonal
2. Hexagon: dayameta diagonal ÷ 0.866 = dayameta diagonal
9. Ngwá ọrụ ọkpụrụkpụ (ịcha mma):
Dayameta ihe dị n'elu:10+0.7 uru ntụaka
10. Usoro mgbako nke taper:
Usoro 1: (Obere dayameta isi - Obere dayameta isi) ÷ (2 × ngụkọta ogologo ogologo nke taper) = ogo
Ha nhata na ịchọta uru ọrụ trigonometric
Usoro 2: Dị Mfe
(Obere dayameta isi - Obere dayameta isi) ÷ 28.7 ÷ Ogologo ogologo = ogo
