Ifomula yokubala eqhelekileyo ye-CNC

1. Ukubalwa kwemisebenzi yetrigonometric

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

2. Ukubalwa kwesantya sokusika
Vc=(π*D*S)/1000
Vc: isantya somgca (m/min)

IP: pi (3.14159)

D: Idayimitha yesixhobo (mm)
S: isantya (rpm)

3. Ubalo lwemali yokutya (ixabiso lika-F)
F=S*Z*Fz
F: Isixa sesondlo (mm/min)

S: isantya (rpm)

Z: inani leeblades
Fz: (ukutya okukwenyani ngokomphetho)

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

ee: XY inothi (mm)

Iradiyasi yesixhobo se-R (mm)

5. Ukubalwa komngxuma wokuphuma kwezinto
Φ=√2R2

X, Y=D/4
Φ: Idayamitha yomngxuma wokuphuma (mm)

Iradiyasi yesixhobo se-R (mm)

D: Idayimitha yesixhobo (mm)

Isithandathu, ukubalwa kobuninzi bezinto eziphathekayo
Q=(ae*ap*F)/1000
Ｑ: Imali yesondlo (cm3/min)

ee: XY inothi (mm)

ap: Z pitch (mm)

7. Ukubalwa kwefidi ngeblade nganye
Fz=hm * √(D/ap )
Fz: Ukutya okuphunyeziweyo ngencakuba nganye hm: Ukutya kwethiyori ngencakuba nganye ap: Z pitch(mm)
D: Idayamitha yencakuba (mm)

8. Die edge processing method
Ubunzulu bokucutshungulwa komphetho = ubukhulu bepleyiti - ubude bomda wokusika + ingcebiso yobhola (0.3D)
U-D uthetha i-diameter yesixhobo

9. Ifomula yexesha lokomba
T(min)=L(min)/N(rpm)*f(mm/rev)
=πDL/1000vf
L: Ubude bomngxuma

N: Inani leenguqu

f: I-coefficient yemali yokutya
D: Idayamitha yokubhola

v: isantya sokusika

Dmba i-coefficient table fz

ububanzi mm

Yondla 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 kwe25

0.376~0,625

10. Ifomula yokubala yamazinyo ityhubhu
1 intshi = 25.4mm = 8 amanqaku

Ishumi elinanye, amandla ehashe (ukudubula umpu)
W=Md*N/97.410
W: amandla afunekayo (KW)
Md: Torque (kg-cm)
N: inani lohlaziyo (rpm)

12. Ifomula yokubala itorque ihamba ngolu hlobo lulandelayo:
Md=1/20*f*ps*r2
f lizinga le feed mm/rev coefficient
r yiradiyasi yentwana yokomba (mm)
α: ukusika ukuxhathisa ratio ps.Kwisondlo esincinci, intsimbi jikelele yi-500kg / m㎡;intsimbi eqhelekileyo yi-300kg/m㎡;
