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: Inombolo yama-revolution
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㎡;
