CNC fua fa'atatau masani

1. Fa'atatauga o galuega fa'atatauga

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

2. Fuafuaina o le saosaoa tipi
Vc=(π*D*S)/1000
Vc: laina saoasaoa (m/min)

π: pi (3.14159)

D: le lautele o meafaigaluega (mm)
S: saoasaoa (rpm)

3. Fuafuaga o le aofa'i o fafaga (tau F)
F=S*Z*Fz
F: Aofa'i fafaga (mm/min)

S: saoasaoa (rpm)

Z: numera o lau
Fz: (fafaga moni i le pito)

4. Fuafuaga o mea maualuga o totoe
Scallop=(ae*ae)/8R
Scallop: maualuga meafaitino totoe (mm)

ae: XY maualuga (mm)

R fua o meafaigaluega (mm)

5. Fuafuaga o mea e sao ai pu
Φ=√2R2

X, Y=D/4
Φ: le lautele o le pu sola (mm)

R fua o meafaigaluega (mm)

D: le lautele o meafaigaluega (mm)

Ono, o le fuafuaina o le aofaʻi o meafaitino
Q=(ae*ap*F)/1000
Ｑ: Aofaiga o fafaga (cm3/min)

ae: XY maualuga (mm)

ap: Z maualuga (mm)

7. Fa'atatauga o mea'ai ile lau
Fz=hm * √(D/ap )
Fz: Fafaga fa'atino ile lau hm: Fafaga fa'ata'ita'i ile lau ap: Z pitch(mm)
D: le lautele o lau (mm)

8. Oti pito faiga faiga
O'o'o le fa'agaoioiga mata'i = mafiafia ipu – maualuga pito pito + pito vili (0.3D)
D o lona uiga o le lautele o meafaigaluega

9. Fuafua taimi viliina
T(min)=L(min)/N(rpm)*f(mm/rev)
=πDL/1000vf
L: Umi ole pu

N: Numera o suiga

f: Fa'aputu aofa'i o fafaga
D: vili le lautele

v: tipi saosaoa

Laulau fa'atatau fa'avili fz

12.8–25

0.175~0.375

sili atu i le 25

0.376~0.625

10. Fuafuaga fa'atatau o nifo fa'agaau
1 inisi = 25.4mm = 8 points

Sefulutasi, solofanua malosi (fana fana)
W=Md*N/97.410
W: mana mana'omia (KW)
Md: Tosi (kg-cm)
N: numera o ta'amilosaga (rpm)

12. O le fua fa'atatau o le torque e fa'apea:
Md=1/20*f*ps*r2
f o le fua fafaga mm/rev coefficient
r o le laina o le vili (mm)
α: tipi le fua faatatau ps.I fafaga laiti, o le uamea lautele o 500kg/m㎡;o le u'amea lafo lautele e 300kg/m㎡;
