CNC nkịtị ngụkọta oge usoro

1. Ngụkọta ọrụ trigonometric

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

2. Ngụkọta nke ịkpụ ọsọ
Vc=(π*D*S)/1000
Vc: ọsọ ahịrị (m/min)

π: pi (3.14159)

D: dayameta ngwá ọrụ (mm)
S: ọsọ (rpm)

3. Ngụkọta ọnụọgụ ndepụta (ọnụahịa F)
F=S*Z*Fz
F: Ọnụ ego nri (mm/min)

S: ọsọ (rpm)

Z: ọnụọgụ agụba
Fz: (Nri nri n'ezie kwa ihu)

4. Ngụkọta nke ihe fọdụrụ n'ịdị elu
Scallop=(ae * ae)/8R
Scallop: elu ihe fọdụrụ (mm)

ihe: XY pitch (mm)

R ngwá ọrụ radius (mm)

5. Ngụkọta nke oghere mgbapụ ihe
Φ=√2R2

X, Y=D/4
Φ: dayameta oghere mgbapụ (mm)

R ngwá ọrụ radius (mm)

D: dayameta ngwá ọrụ (mm)

Isii, ngụkọta nke ego nke ihe onwunwe
Q=(ae*ap*F)/1000
: Ọnụ ego nri (cm3/min)

ihe: XY pitch (mm)

ap: mpi Z (mm)

7. Ngụkọta ndepụta kwa agụba
Fz=hm * √(D/ap)
Fz: Nri etinyere n'otu agụba hm: Ozizi ndepụta n'otu agụba ap: Z pitch(mm)
D: dayameta agụba (mm)

8. Die onu nhazi usoro
Omimi nhazi nke mbepụ ọnụ = ọkpụrụkpụ efere – mbepụ ọnụ ọnụ elu + nkuku n'ọnụ (0.3D)
D pụtara dayameta ngwá ọrụ

9. Usoro oge igwu mmiri
T(min)=L(min)/N(rpm)*f(mm/rev)
= πDL/1000vf
L: Ogologo oghere

N: Ọnụọgụ mgbanwe

f: Ọnụ ego nri
D: dayameta egwu egwu

v: igbubi ọsọ

Kpọọ ọnụ ọgụgụ tebụl fz

dayameta mm

0.05-0.15

6.4-12.8

0.10-0.25

12.8-25

0.175-0.375

0,376-0,625

10. Usoro nchịkọta nke ezé tube
1 inch = 25.4mm = 8 isi

Iri na otu, ike inyinya (nkpu egbe)
W=Md*N/97.410
W: ike achọrọ (KW)
Md: Torque (kg-cm)
N: ọnụọgụ mgbanwe (rpm)

12. Usoro mgbako torque bụ nke a:
Md=1/20*f*ps*r2
f bụ ọnụ ọgụgụ ndepụta mm/ntụgharị anya
r bụ radius nke egwu egwu (mm)
α: oke nguzogide ps. Na obere ndepụta, nchara n'ozuzu bụ 500kg / m㎡; ihe nkedo n'ozuzu bụ 300kg / m㎡;
