Hoʻohana maʻamau (thread) helu helu no ka CNC machining, maʻalahi a maʻalahi hoʻi e hoʻomaopopo

3. ʻO ke kumu maʻamau no ka hoʻololi ʻana i nā niho Pelekania i niho metric:

Ka helu ÷ lihilihi × 25.4 = niho anawaena waho (e like me ka luna)

Laʻana 1: (3/8-24)

3÷8×25.4＝9.525(anawaena niho waho)

25.4÷24＝1.058 (kiʻi kiko)

A laila ʻo 3/8-24 i hoʻololi ʻia i nā niho metric: M9.525×1.058

4. ʻO ke kumu no ka hoʻololi ʻana i nā niho ʻAmelika i nā niho metric:

Laʻana: 6-32

6-32 (0.06+0.013)/code×6＝0.138

0.138×25.4＝3.505 (ka anawaena o waho o ka niho)

25.4÷32＝0.635 (ka mamao niho)

A laila ʻo 6-32 i hoʻololi ʻia i nā niho metric: M3.505×0.635

1. Ka helu ana o ka puka anawaena o loko:

ʻO ke anawaena o waho o ka niho - 1/2 × ka pitch niho:

M3.505－1/2×0.635＝3.19

A laila, ʻo ke anawaena o loko o 6-32 he 3.19

2. Extrusion uea paʻi i loko puka algorithm:

Ka helu maʻalahi o ka anawaena puka haʻahaʻa 1:

Ke anawaena o waho o ka niho - (piʻi niho × 0.4250.475)/code = anawaena puka haʻahaʻa

Laʻana 1: M6×1.0

M6-(1.0×0.425)=5.575 (ka puka haʻahaʻa kiʻekiʻe loa)

M6-(1.0×0.475)=5.525(ka liʻiliʻi)

Laʻana 2: ʻO ka helu helu maʻalahi no ke anawaena o loko o ka lua i paʻi ʻia e ka uwea ʻoki:

M6－(1.0×0.85)=5.15 (ʻoi loa)

M6－(1.0×0.95)＝5.05(ka liʻiliʻi)

M6－(Ke kani niho×0.860.96)/code=puka haʻahaʻa

Laʻana 3: M6×1.0＝6-1.0＝5.0+0.05＝5.05

5. ʻO ke kumu maʻalahi no ka helu ʻana i ke anawaena o waho o nā niho paʻi:

1. Anawaena - 0.01 × 0.645 × pitch (pono e hele a kū)

Laʻana 1: M3×0.5＝3-0.01×0.645×0.5＝2.58 (anawaena waho)

Laʻana 2: M6×1.0＝6-0.1×0.645×1.0＝5.25 (anawaena waho)

6. Ka helu helu no ka anawaena o ka niho metric: (Ka helu niho piha)

Laʻana 1: M3×0.5＝3-0.6495×0.5＝2.68 (anawaena waho ma mua o ka huli ʻana)

Laʻana 2: M6×1.0＝6-0.6495×1.0＝5.35 (anawaena waho ma mua o ka huli ʻana)

7. Ka hohonu anawaena o waho (ka anawaena o waho)

Ka anawaena ÷ 25.4×Kuhi niho=Ka anawaena o waho ma mua o ka hili ʻana

Laʻana: 4.1÷25.4×0.8 (pua pua)=0.13 0.13 ka hohonu o ka embossing.

8. Ke kumu hoʻololi diagonal no nā mea polygonal:

1. Ka huinaha: diagonal anawaena × 1.414 = diagonal anawaena

2. Pentagon: Diagonal anawaena × 1.2361 = Diagonal anawaena

3. Hexagon: Anawaena o na aoao kuee × 1.1547 = Anawaena o na kihi kue.

Kumu 2: 1. ʻEhā kihi: diagonal anawaena ÷ 0.71 = diagonal anawaena

2. Hexagon: anawaena diagonal ÷ 0.866 = anawaena diagonal

9. Mānoanoa mea hana (ʻoki pahi):

Ke anawaena o waho ÷ 10+0.7 waiwai kuhikuhi

10. Ka helu helu o ka taper:

Kumu 1: (Anawaena poʻo nui - Anawaena poʻo liʻiliʻi) ÷ (2 × ka lōʻihi o ka liʻiliʻi) = Degere

Ua like ia me ka imi ana i ka waiwai hana trigonometric

Kumu 2: Maʻalahi

(Ke anawaena poʻo nui - Ke anawaena poʻo liʻiliʻi) ÷ 28.7 ÷ Ka lōʻihi piha = Degere
