ʻO ke kumu helu helu maʻamau CNC

1. Heluhelu i na hana trigonometric

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

2. Ka helu ʻana i ka wikiwiki ʻoki
Vc=(π*D*S)/1000
Vc: ka māmā laina (m/min)

π: pi (3.14159)

D: anawaena mea hana (mm)
S: ka māmā holo (rpm)

3. Ka helu ʻana o ka nui hānai (waiwai F)
F=S*Z*Fz
F: Ka nui hānai (mm/min)

S: ka māmā holo (rpm)

Z: ka helu o nā lau
Fz: (hānai maoli no kēlā me kēia lihi)

4. Heluhelu i ke koena mea kiekie
Scallop=(ae*ae)/8R
Scallop: koena mea kiʻekiʻe (mm)

ae: XY pitch (mm)

R radius mea hana (mm)

5. Ka helu ʻana o ka lua pakele waiwai
Φ=√2R2

X, Y=D/4
Φ: ke anawaena puka pakele (mm)

R radius mea hana (mm)

D: anawaena mea hana (mm)

ʻEono, ka helu ʻana i ka nui o nā mea
Q=(ae*ap*F)/1000
Ｑ: Ka nui hānai (cm3/min)

ae: XY pitch (mm)

ap: Z pitch (mm)

7. Ka helu ʻana i ka ʻai no kēlā me kēia lau
Fz=hm * √(D/ap )
Fz: Hānai i hoʻokō ʻia no kēlā me kēia lau hm: Hānai manaʻo no kēlā me kēia lau ap: Z pitch(mm)
D: anawaena maka (mm)

8. Ke ano hana lihi make
ʻO ka hohonu o ka ʻoki ʻoki ʻana = ka mānoanoa o ka pā – ke kiʻekiʻe o ka ʻoki ʻoki a me ke kihi drill (0.3D)
ʻO D ke anawaena mea hana

9. ʻO ke ʻano o ka manawa wili
T(min)=L(min)/N(rpm)*f(mm/rev)
=πDL/1000vf
L: Ka lōʻihi o ka puka

N: Ka helu o nā kipi

f: Ka helu helu hānai
D: wili anawaena

v: ʻoki māmā

Pākaukau hoʻopaʻa wili fz

anawaena mm

Hānai 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

ma luna o 25

0.376~0.625

10. Ka helu helu o na niho paipu
1 iniha = 25.4mm = 8 helu

He ʻumikūmākahi, horsepower (gun drill)
W=Md*N/97.410
W: mana koi (KW)
Md: Torque (kg-cm)
N: helu o nā hoʻololi (rpm)

12. Penei ke ano o ka helu torque.
Md=1/20*f*ps*r2
ʻO f ka helu hānai mm/rev coefficient
r ka radius o ka bit drill (mm)
α: ʻoki kūʻē lākiō ps. Ma ka hānai liʻiliʻi, ʻo ke kila maʻamau he 500kg/m㎡; ʻo ka hao nui he 300kg/m㎡;
