CNC sib piv cov qauv

1. Kev suav ntawm cov haujlwm trigonometric

1.tgθ=b/a ctgθ=a/b
2. Sinθ=b/c Cos=a/c

2. Kev suav ntawm kev txiav ceev
Vc=(π*D*S)/1000
Vc: kab ceev (m / min)

π: pi (3.14159)

D: Tool diameter (mm)
S: ceev (rpm)

3. Kev xam tus nqi pub (F tus nqi)
F = S * Z * Fz
F: Pub tus nqi (mm/min)

S: ceev (rpm)

Z: tus naj npawb ntawm cov hniav
Fz: (qhov tseeb pub ib ntug)

4. Kev suav cov khoom seem ntawm qhov siab
Scallop=(ae*ae)/8R
Scallop: residual khoom qhov siab (mm)

Ae: XY suab (mm)

R cuab tam radius (mm)

5. Kev suav cov khoom khiav tawm qhov
Φ = √2R2

X, Y = D/4
Φ: khiav qhov taub (mm)

R cuab tam radius (mm)

D: Tool diameter (mm)

Rau, kev suav ntawm cov khoom siv
Q=(ae*ap*F)/1000
Q: Pub tus nqi (cm3 / min)

Ae: XY suab (mm)

ap: Z suab (mm)

7. Kev suav pub rau ib rab hniav
Fz=hm * √(D/ap)
Fz: Implemented feed per blade hm: Theoretical feed per blade ap: Z pitch(mm)
D: hniav taub (mm)

8. Tuag ntug txheej txheem
Txiav ntug ua qhov tob = phaj thickness - txiav ntug qhov siab + laum taub (0.3D)
D txhais tau tias lub cuab tam txoj kab uas hla

9. Drilling lub sij hawm formula
T(min) = L(min)/N(rpm)*f(mm/rev)
= πDL/1000vf
L: Qhov ntev

N: Number of revolutions

f: Pub tus nqi coefficient
D: Laum txoj kab uas hla

v: txiav ceev

Laum coefficient rooj fz

txoj kab uas hla mm

Pub mm/rev

1.6 ~ 3.2 hli

0.025 ~ 0.075 hli

3.2-6.4

0.05-0.15 Nws

6.4-12.8 Nws

0.10-0.25 Nws

12.8-25.0 Nws

0.175 ~ 0.375 hli

tshaj 25

0.376 ~ 0.625 hli

10. Kev suav cov qauv ntawm cov hniav hniav
1 nti = 25.4mm = 8 points

Kaum ib, horsepower ( phom laum)
W=Md*N/97.410
W: xav tau lub zog (KW)
Md: Torque (kg-cm)
N: tus naj npawb ntawm kev hloov pauv (rpm)

12. Cov mis laij lej torque yog raws li hauv qab no:
Md=1/20*f*ps*r2
f yog tus nqi pub mm/rev coefficient
r yog lub vojvoog ntawm lub laum me ntsis (mm)
α: txiav kuj piv ps. Hauv kev pub me me, cov hlau dav dav yog 500kg / m㎡; cam khwb cia hlau dav dav yog 300kg / m㎡;
