CNC Common Calculation formula

1. Kuwerengera kwa ntchito za trigonometric

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

2. Mawerengedwe a kudula liwiro
Vc=(π*D*S)/1000
Vc: liwiro la mzere (m/min)

π: pi (3.14159)

D: chida awiri (mm)
S: liwiro (rpm)

3. Kuwerengera kuchuluka kwa chakudya (mtengo wa F)
F=S*Z*Fz
F: Kuchuluka kwa chakudya (mm/mphindi)

S: liwiro (rpm)

Z: chiwerengero cha masamba
Fz: (chakudya chenicheni pamphepete)

4. Kuwerengera kutalika kwa zinthu zotsalira
Scallop=(ae*ae)/8R
Scallop: kutalika kwa zinthu zotsalira (mm)

ae: XY phula (mm)

R chida utali (mm)

5. Mawerengedwe a chuma kuthawa dzenje
Φ=√2R2

X, Y=D/4
Φ: kutalika kwa dzenje (mm)

R chida utali (mm)

D: chida awiri (mm)

Chachisanu ndi chimodzi, kuwerengera kuchuluka kwa zinthu
Q=(ae*ap*F)/1000
Ｑ: Kuchuluka kwa chakudya (cm3/min)

ae: XY phula (mm)

ap: Z phula (mm)

7. Kuwerengera chakudya pa tsamba
Fz=hm * √(D/ap )
Fz: Chakudya chokhazikitsidwa pa tsamba hm: Chakudya chongoyerekeza pa tsamba ap: Z pitch(mm)
D: m'mimba mwake (mm)

8. Die m'mphepete processing njira
Kudula m'mphepete mwakuya = makulidwe a mbale - kutalika kwa m'mphepete + kubowola nsonga (0.3D)
D amatanthawuza kutalika kwa chida

9. Kubowola nthawi formula
T(min)=L(mphindi)/N(rpm)*f(mm/rev)
=πDL/1000vf
L: Kutalika kwa dzenje

N: Chiwerengero cha zosintha

f: Kuchulukitsa kuchuluka kwa chakudya
D: Kubowola m'mimba mwake

v :kudula liwiro

Dulani tebulo la coefficient fz

awiri mm

Kudyetsa 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

pa 25

0.376-0.625

10. Kuwerengera chilinganizo cha mano chubu
1 inchi = 25.4mm = 8 mfundo

Khumi ndi chimodzi, mphamvu zamahatchi (kubowola mfuti)
W=Md*N/97.410
W: mphamvu yofunikira (KW)
Md: Torque (kg-cm)
N: chiwerengero cha kusintha (rpm)

12. Njira yowerengera torque ili motere:
Md=1/20*f*ps*r2
f ndiye kuchuluka kwa ma feed mm/rev coefficient
r ndiye kutalika kwa kubowola (mm)
α: kudula kukana chiŵerengero ps.Mu chakudya yaing'ono, zitsulo ambiri ndi 500kg/m㎡;wamba kuponyedwa chitsulo ndi 300kg/m㎡;
