Tsarin lissafin gama gari na CNC

1. Lissafin ayyukan trigonometric

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

2. Lissafin saurin yankewa
Vc=(π*D*S)/1000
Vc: saurin layi (m/min)

π: pi (3.14159)

D: diamita na kayan aiki (mm)
S: gudun (rpm)

3. Lissafin adadin abinci (darajar F)
F=S*Z*Fz
F: Adadin ciyarwa (mm/min)

S: gudun (rpm)

Z: adadin ruwan wukake
Fz: (ainihin ciyarwa a kowane gefe)

4. Lissafi na ragowar kayan tsawo
Scallop = (ae * ae)/8R
Scallop: ragowar kayan tsawo (mm)

ae: XY farar (mm)

R kayan aiki radius (mm)

5. Lissafin ramin tserewa kayan aiki
Φ=√2R2

X, Y=D/4
Φ: Diamita na tserewa (mm)

R kayan aiki radius (mm)

D: diamita na kayan aiki (mm)

Shida, lissafin adadin kayan
Q=(ae*ap*F)/1000
: Adadin ciyarwa (cm3/min)

ae: XY farar (mm)

ap: Zurfin Z (mm)

7. Lissafin ciyarwa kowace ruwa
Fz=hm* √(D/ap)
Fz: Aiwatar da ciyarwa kowane ruwa hm: Bayanin ka'idar akan kowane ruwa ap: Z farar (mm)
D: diamita na ruwa (mm)

8. Hanyar sarrafa baki
Zurfin aikin yankan gefen = kauri farantin - yanke tsayin tsayi + tukwici (0.3D)
D yana nufin diamita na kayan aiki

9. Tsarin lokacin hakowa
T(min)=L(min)/N(rpm)*f(mm/rev)
= DL/1000vf
L: Tsawon rami

N: Adadin juyin juya hali

f: Yawan adadin ciyarwa
D: Haɗa diamita

v: saurin yankewa

1 inch = 25.4mm = maki 8

Goma sha ɗaya, ƙarfin doki (bindigo)
W=Md*N/97.410
W: ikon da ake buƙata (KW)
Md: Torque (kg-cm)
N: adadin juyi (rpm)

12. Tsarin lissafin magudanar ruwa shine kamar haka.
Md=1/20*f*ps*r2
f shine ƙimar ciyarwar mm/rev coefficient
r shine radius na rawar rawar soja (mm)
α: yankan juriya rabo ps.A cikin ƙaramin abinci, babban ƙarfe shine 500kg / m㎡;Babban simintin ƙarfe shine 300kg/m㎡;
