CNC qaacidada xisaabinta guud

1. Xisaabinta hawlaha trigonometric

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

2. Xisaabinta xawaaraha goynta
Vc=(π*D*S)/1000
Vc: Xawaaraha khadka (m/min)

π: pi (3.14159)

D: dhexroorka qalabka (mm)
S: xawaaraha (rpm)

3. Xisaabinta qadarka quudinta (qiimaha F)
F=S*Z*Fz
F: Qadarka quudinta (mm/min)

S: xawaaraha (rpm)

Z: tirada daab
Fz: (quudinta dhabta ah geeskiiba)

4. Xisaabinta dhererka walxaha haraaga ah
Scallop=(ae*ae)/8R
Dhafka: dhererka walxaha haraaga ah (mm)

ae: garoonka XY (mm)

Radius qalab R (mm)

5. Xisaabinta godka fakashada walxaha
Φ=√2R2

X, Y=D/4
Φ: dhexroorka godka baxsadka (mm)

Radius qalab R (mm)

D: dhexroorka qalabka (mm)

Lix, xisaabinta tirada alaabta
Q=(ae*ap*F)/1000
: Qadarka quudinta (cm3/min)

ae: garoonka XY (mm)

ap: booska Z (mm)

7. Xisaabinta quudinta daabkiiba
Fz=hm * √(D/ap)
Fz: Quudinta la hirgaliyay midkiiba hm: quudinta aragtida halkii daab ap: garoonka Z (mm)
D: dhexroorka daabka (mm)

8. Habka habaynta cidhifyada
Goynta qoto dheer ee habaynta cidhifka = dhumucda saxanka - goynta dhererka cidhifka + caarada dalool (0.3D)
D macnaheedu waa dhexroorka qalabka

9. Qaaciddada wakhtiga qodista
T(min)=L(min)/N(rpm)*f(mm/rev)
= πDL/1000vf
L: Dhererka daloolka

N: Tirada kacaanka

f: Qiyaasta qadarka quudinta
D: Dhexroor qodista

v: xawaaraha goynta

Qodista miiska isku-dhafka fz

dhexroor mm

Quudi 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

ka weyn 25

0.376 ~ 0.625

10. Xisaabinta caanaha ilka tuubada
1 inji = 25.4mm = 8 dhibcood

Kow iyo toban, xoog faras (qoryaha layli)
W=Md*N/97.410
W: awooda loo baahan yahay (KW)
Md: Torque (kg-cm)
N: tirada kacaanka (rpm)

12. Habka xisaabinta torque waa sida soo socota:
Md=1/20*f*ps*r2
f waa qiyaasta quudinta mm/rev coefficient
r waa radius birta laydhka (mm)
α: goynta saamiga iska caabinta ps.Quudinta yar yar, birta guud waa 500kg / m㎡;birta guud ee kabka waa 300kg/m㎡;
