8. Usoro mgbako nke square edere na okirikiri
① See okirikiri (D) ka ịchọta akụkụ nke ọzọ nke square (S elu)
S=0.7071D bụ dayameta × 0.7071
② Chọta okirikiri (D) site n'akụkụ nke ọzọ nke square (S elu)
D = 1.414S akụkụ nke ọzọ × 1.414
9. Ngụkọta usoro maka square megidere akụkụ na-emegide akụkụ na oyi isiokwu usoro
① Chọta akụkụ na-abụghị (e) site na akụkụ nke ọzọ (S) nke square mpụta
e = 1.4s bụ akụkụ nke ọzọ (s) × 1.4 paramita
② Chọta akụkụ na-emegide (e) nke akụkụ (s) nke ọzọ nke square dị n'ime
e = 1.45s bụ akụkụ nke ọzọ (s) × 1.45 ọnụọgụ
10. Usoro mgbako olu hexagon
s20.866 × H / m / k pụtara n'akụkụ akụkụ × akụkụ dị n'akụkụ × 0.866 × ịdị elu ma ọ bụ ọkpụrụkpụ.
11. Usoro mgbako maka mkpịrị (cone) olu

12. Usoro mgbako maka olu okirikiri (dị ka isi okirikiri)
3.1416h2 (Rh/3) bụ 3.1416 × ịdị elu × ịdị elu × (radius - ịdị elu ÷ 3).
13. Usoro mgbako maka machining akụkụ nke esịtidem eri taps
1. Ngụkọta mgbata isi dayameta D0
D0=D＋(0.866025P/8)×(0.5~1.3) bụ isi nha nke mgbata nnukwu dayameta eri + 0.866025 pitch÷8×0.5~1.3.
Rịba ama: Nhọrọ nke 0.5 ~ 1.3 kwesịrị ikpebi dịka ọkwa ọkwa si dị. Ka ọnụ ahịa pitch buru ibu, ka ekwesịrị iji ọnụọgụ ọnụọgụ dị ntakịrị. N'aka nke ọzọ, ka ọnụ ahịa pitch dị ntakịrị, nnukwu ọnụọgụ kwekọrọ kwesịrị ịdị.
2. Ngụkọta dayameta ụda mgbata (D2)
D2=(3×0.866025P)/8, ya bụ, kpatụ dayameta=3×0.866025×pitch÷8
3. Ngụkọta dayameta mgbata (D1)
D1=(5×0.866025P)/8 bụ mgbata dayameta = 5×0.866025×pitch÷8
Iri na anọ,
Usoro mgbako nke ogologo ihe maka isi oyi na-akpụ ụdị dị iche iche
Usoro olu nke okirikiri mara amara bụ dayameta × dayameta × 0.7854 × ogologo ma ọ bụ radius × radius × 3.1416 × ogologo. Ya bụ, d2×0.7854×L ma ọ bụ R2×3.1416×L
Mgbe ị na-agbakọ, olu X÷diameter ÷ dayameta ÷ 0.7854 ma ọ bụ X÷radius÷radius÷3.1416 nke ihe achọrọ bụ ogologo ihe ahụ.
Usoro kọlụm = X/(3.1416R2) ma ọ bụ X/0.7854d2
N'ime usoro ahụ, X na-anọchi anya uru olu nke ihe achọrọ;
