Mokhoa o tloaelehileng oa ho bala oa CNC

1. Palo ea mesebetsi ea trigonometric

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

2. Palo ea lebelo la ho itšeha
Vc=(π*D*S)/1000
Vc: lebelo la mohala (m/min)

π: pi (3.14159)

D: bophara ba sesebelisoa (mm)
S: lebelo (rpm)

3. Palo ea palo ea lijo (boleng ba F)
F=S*Z*Fz
F: Chelete ea lijo (mm/min)

S: lebelo (rpm)

Z: palo ea li-blades
Fz: (phepelo ea 'nete ka lehlakoreng le leng)

4. Palo ea bolelele ba thepa e setseng
Scallop=(ae*ae)/8R
Scallop: bolelele ba thepa e setseng (mm)

ae: XY molumo (mm)

R sebaka sa lisebelisoa (mm)

5. Palo ea thepa ea ho phonyoha lesoba
Φ=√2R2

X, Y=D/4
Φ: bophara ba lesoba la ho baleha (mm)

R sebaka sa lisebelisoa (mm)

D: bophara ba sesebelisoa (mm)

Botšelela, palo ea palo ea lintho tse bonahalang
Q=(ae*ap*F)/1000
Ｑ: Chelete ea lijo (cm3/min)

ae: XY molumo (mm)

ap: Z molumo (mm)

7. Palo ea lijo ka lehare
Fz=hm * √(D/ap )
Fz: Phepelo e kentsoeng ka lehare hm: Phepelo ea khopolo-taba ka lehare ap: Z pitch(mm)
D: bophara ba lehare (mm)

8. Mokhoa oa ho sebetsa ka thata
Botebo bo tebileng ba ho sebetsa = botenya ba poleiti - bophahamo bo sehiloeng + ntlha ea ho phunya (0.3D)
D e bolela bophara ba sesebelisoa

9. Foromo ea nako ea ho cheka
T(mots)=L(mots)/N(rpm)*f(mm/rev)
=πDL/1000vf
L: Bolelele ba lesoba

N: Palo ea liphetohelo

f: Fepa palo ea coefficient
D: Bophahamo ba ho cheka

v: lebelo le sehang

Eketsa tafole ea coefficient fz

bophara mm

Fepa 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

lilemo tse fetang 25

0.376~0.625

10. Mokhoa oa ho bala oa meno a tube
1 inch = 25.4mm = lintlha tse 8

Leshome le motso o mong, matla a lipere (ho phunya lithunya)
W=Md*N/97.410
W: matla a hlokahalang (KW)
Md: Torque (kg-cm)
N: palo ea liphetohelo (rpm)

12. Foromo ea lipalo tsa torque e tjena:
Md=1/20*f*ps*r2
f ke sekhahla sa phepelo mm/rev coefficient
r ke sebaka sa sebaka sa ho phunya (mm)
α: ho itšeha karo-karolelano ea ps. Lijong tse nyane, tšepe e akaretsang ke 500kg/m㎡; tšepe ea tšepe e akaretsang ke 300kg/m㎡;

Lisebelisoa tsa Xinfa CNC li na le boleng bo botle le ho tšoarella ho matla, bakeng sa lintlha, ka kopo sheba: https://www.xinfatools.com/cnc-tools/
