CNC isanzwe yo kubara

1. Kubara imikorere ya trigonometric

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

2. Kubara umuvuduko wo guca
Vc = (π * D * S) / 1000
Vc: umuvuduko wumurongo (m / min)

π: pi (3.14159)

D: diameter igikoresho (mm)
S: umuvuduko (rpm)

3. Kubara ingano y'ibiryo (F agaciro)
F = S * Z * Fz
F: Amafaranga yo kugaburira (mm / min)

S: umuvuduko (rpm)

Z: umubare wibyuma
Fz: (ibiryo nyabyo kuruhande)

4. Kubara uburebure bwibikoresho bisigaye
Scallop = (ae * ae) / 8R
Igicucu: uburebure bwibikoresho bisigaye (mm)

ae: Ikibanza cya XY (mm)

R igikoresho cya radiyo (mm)

5. Kubara umwobo wo guhunga
Φ = √2R2

X, Y = D / 4
: Guhunga umwobo wa diameter (mm)

R igikoresho cya radiyo (mm)

D: diameter igikoresho (mm)

Gatandatu, kubara umubare wibikoresho
Q = (ae * ap * F) / 1000
.: Kugaburira amafaranga (cm3 / min)

ae: Ikibanza cya XY (mm)

ap: Z ikibanza (mm)

7. Kubara ibiryo kuri buri cyuma
Fz = hm * √ (D / ap)
Fz: Ibiryo byashyizwe mubikorwa kuri hm: Ibiryo bya Theoretical kuri blade ap: Z ikibanza (mm)
D: diameter ya blade (mm)

8. Gupfa uburyo bwo gutunganya
Gukata inkombe yo gutunganya ubujyakuzimu = uburebure bw'isahani - gukata uburebure bwa metero + umwitozo (0.3D)
D bisobanura igikoresho cya diameter

9. Igihe cyo gucukura
T (min) = L (min) / N (rpm) * f (mm / rev)
= πDL / 1000vf
L: Uburebure

N: Umubare wa revolisiyo

f: Kugaburira amafaranga coefficient
D: Dimetero

v: kugabanya umuvuduko

Imyitozo ya coefficient kumeza fz

diameter mm

Kugaburira mm / rev

1.6 ~ 3.2

0.025 ~ 0.075

3.2 ~ 6.4

0.05 ~ 0.15

6.4 ~ 12.8

0.10 ~ 0.25

12.8 ~ 25

0.175 ~ 0.375

hejuru ya 25

0.376 ~ 0.625

10. Ibiharuro byo kubara amenyo yigituba
1 cm = 25.4mm = amanota 8

Cumi n'umwe, imbaraga zifarashi (imyitozo y'imbunda)
W = Md * N / 97.410
W: imbaraga zisabwa (KW)
Md: Torque (kg-cm)
N: umubare wimpinduramatwara (rpm)

12. Inzira yo kubara ya torque niyi ikurikira:
Md = 1/20 * f * ps * r2
f ni igipimo cyo kugaburira mm / rev coefficient
r ni radiyo ya bito bito (mm)
α: kugabanya igipimo cyo kurwanya ps. Mu biryo bito, ibyuma rusange ni 500kg / m㎡; icyuma rusange gikozwe ni 300kg / m㎡;
