Feem ntau siv (xov) cov qauv siv rau CNC machining, yooj yim thiab yooj yim to taub

3. Cov qauv dav dav rau kev hloov cov hniav British rau hauv cov hniav metric:

Tus lej ÷ denominator × 25.4 = tus hniav sab nraud (ib yam li saum toj no)

Piv txwv 1: (3/8-24)

3 × 8 × 25.4 × 9.525 (tus hniav sab nraud)

25.4 ÷ 24 × 1.058 (Metric suab)

Tom qab ntawd 3/8-24 hloov mus rau metric hniav yuav tsum yog: M9.525 × 1.058

4. Cov mis rau hloov cov hniav Asmeskas rau cov hniav metric:

Piv txwv li: 6-32

6-32 (0.06+0.013)/code × 6＝0.138

0.138 × 25.4 × 3.505 (txoj kab uas hla ntawm tus hniav)

25.4 ÷ 32 ＝ 0.635 (hmoov nrug)

Tom qab ntawd 6-32 hloov mus rau hauv metric hniav yuav tsum yog: M3.505 × 0.635

1. Kev suav cov mis ntawm lub qhov puab txoj kab uas hla:

Sab nraud txoj kab uas hla ntawm cov hniav - 1/2 × cov hniav yuav tsum yog:

M3.505－1/2 × 0.635＝3.19

Tom qab ntawd lub puab kab ntawm 6-32 yuav tsum yog 3.19

2. Extrusion hlau tapping puab qhov algorithm:

Yooj yim xam cov mis ntawm qis qhov taub 1:

Hniav sab nraud - (cov hniav pitch × 0.4250.475) / code = qis qhov taub

Piv txwv 1: M6 × 1.0

M6-(1.0 × 0.425) = 5.575 (qhov siab tshaj qhov qis dua)

M6-(1.0 × 0.475) = 5.525 (tsawg kawg)

Piv txwv 2: Cov mis laij lej yooj yim rau lub puab txoj kab uas hla ntawm lub qhov tapped los ntawm kev txiav hlau:

M6 - (1.0 × 0.85) = 5.15 (qhov siab tshaj)

M6 - (1.0 × 0.95) × 5.05 (tsawg kawg)

M6－(Tooth pitch × 0.860.96)/code=lower aperture

Piv txwv 3: M6 × 1.0＝6-1.0＝5.0+0.05＝5.05

5. Cov qauv yooj yim rau kev xam cov kab sab nraud ntawm cov hniav xovxwm:

1. Txoj kab uas hla - 0.01 × 0.645 × suab (yuav tsum dhau thiab nres)

Piv txwv 1: M3 × 0.5＝3-0.01 × 0.645 × 0.5＝2.58 (sab nraud txoj kab uas hla)

Piv txwv 2: M6 × 1.0＝6-0.1 × 0.645 × 1.0＝5.25 (sab nraud txoj kab uas hla)

6. Kev suav cov mis rau metric hniav dov txoj kab uas hla: (Full tooth calculation)

Piv txwv 1: M3 × 0.5＝3-0.6495 × 0.5＝2.68 (txoj kab uas hla ua ntej tig)

Piv txwv 2: M6 × 1.0＝6-0.6495 × 1.0＝5.35 (txoj kab uas hla ua ntej tig)

7. Embossed sab nraud qhov tob (sab nraud txoj kab uas hla)

Sab nraud txoj kab uas hla ÷ 25.4 × Hniav pitch = Sab nraud txoj kab uas hla ua ntej embossing

Piv txwv li: 4.1÷25.4 × 0.8 (paj suab) = 0.13 Qhov tob embossing yuav tsum yog 0.13

8. Diagonal conversion formula rau polygonal ntaub ntawv:

1. Square: kab pheeb ces kaum × 1.414 = kab pheeb ces kaum

2. Pentagon: kab pheeb ces kaum × 1.2361 = Diagonal txoj kab uas hla

3. Hexagon: Diameter ntawm opposite sab × 1.1547 = Txoj kab uas hla ntawm opposite fab

Formula 2: 1. Plaub fab: kab pheeb ces kaum ÷ 0.71 = kab pheeb ces kaum

2. Hexagon: kab pheeb ces kaum ÷ 0.866 = kab pheeb ces kaum

9. Cov cuab yeej thickness (txiav riam):

Cov khoom siv sab nraud ÷ 10 + 0.7 siv tus nqi

10. Kev suav cov qauv ntawm taper:

Formula 1: (Lub taub hau loj - Lub taub hau me me) ÷ (2 × tag nrho ntev ntawm taper) = Degrees

Yog sib npaug los nrhiav tus nqi trigonometric muaj nuj nqi

Formula 2: Yooj yim

(Lub taub hau loj - Lub taub hau me me) ÷ 28.7 ÷ Tag nrho ntev = Degrees
