Ifomula yokubala evamile ye-CNC

1. Ukubalwa kwemisebenzi ye-trigonometric

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

2. Ukubalwa kwejubane lokusika
Vc=(π*D*S)/1000
Vc: isivinini somugqa (m/min)

π: pi (3.14159)

D: Ububanzi bethuluzi (mm)
S: isivinini (rpm)

3. Ukubalwa kwenani lokuphakelayo (inani lika-F)
F=S*Z*Fz
F: Inani lokuphakelayo (mm/min)

S: isivinini (rpm)

Z: inani lama-blades
Fz: (okuphakelayo kwangempela ngomphetho ngamunye)

4. Ukubalwa kobude bezinto ezisele
Scallop=(ae*ae)/8R
I-Scallop: ubude bezinto ezisele (mm)

ae: XY pitch (mm)

Irediyasi yethuluzi lika-R (mm)

5. Ukubalwa kwembobo yokuphunyuka kwezinto
Φ=√2R2

X, Y=D/4
Φ: ububanzi bembobo yokuphunyuka (mm)

Irediyasi yethuluzi lika-R (mm)

D: Ububanzi bethuluzi (mm)

Isithupha, ukubalwa kwenani lempahla
Q=(ae*ap*F)/1000
Ｑ: Inani lokuphakelayo (cm3/min)

ae: XY pitch (mm)

i-ap: i-Z pitch (mm)

7. Ukubalwa kokuphakelayo ngeblade ngayinye
Fz=hm * √(D/ap )
Fz: Okuphakelayo okusetshenzisiwe blade ngayinye hm: Isiphakeli sethiyori ngeblade ngayinye ap: Z pitch(mm)
D: ububanzi be-blade (mm)

8. Indlela yokucubungula i-Die edge
Ukujula kokucubungula onqenqemeni = ukujiya kwepuleti - ukuphakama konqenqemeni + ithiphu lokubhoboza (0.3D)
U-D usho ububanzi bethuluzi

9. Ifomula yesikhathi sokumba
T(min)=L(min)/N(rpm)*f(mm/rev)
=πDL/1000vf
L: Ubude bembobo

N: Inani lamavukelambuso

f: I-coefficient yenani lokuphakelayo
D: I-diameter yokubhoboza

v: ijubane lokusika

Dweba ithebula le-coefficient fz

ububanzi mm

Okuphakelayo 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

ngaphezulu kwama-25

0.376~0.625

10. Ifomula yokubala yamazinyo eshubhu
1 intshi = 25.4mm = 8 amaphuzu

Ishumi nanye, amandla amahhashi (ukudubula isibhamu)
W=Md*N/97.410
W: amandla adingekayo (KW)
Md: Torque (kg-cm)
N: inombolo yama-revolution (rpm)

12. Ifomula yokubala yetorque imi kanje:
Md=1/20*f*ps*r2
f isilinganiso sokuphakelayo mm/rev coefficient
r irediyasi ye-drill bit (mm)
α: ukusika ukumelana nesilinganiso ps.Ekuphakeleni okuncane, insimbi ejwayelekile ingu-500kg/m㎡;insimbi evamile yokusansimbi ingu-300kg/m㎡;

Amathuluzi e-Xinfa CNC anekhwalithi enhle kakhulu nokuqina okuqinile, ukuze uthole imininingwane, sicela uhlole: https://www.xinfatools.com/cnc-tools/
