CNC tātai tātai noa

1. Te tātai i ngā mahi pākoki

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

2. Te tatauranga o te tere tapahi
Vc=(π*D*S)/1000
Vc: tere raina (m/mene)

π: pi (3.14159)

D: taputapu diameter (mm)
S: tere (rpm)

3. Te tatau i te nui o te kai (F uara)
F=S*Z*Fz
F: Rahi whangai (mm/min)

S: tere (rpm)

Z: te maha o nga matatahi
Fz: (whangai tūturu mo ia tapa)

4. Te tātaitanga o te teitei rawa o te toenga
Scallop=(ae*ae)/8R
Mahunga: teitei rawa te toenga (mm)

ae: XY pitch (mm)

R pūtoro taputapu (mm)

5. Te tataunga o te kohao mawhiti rawa
Φ=√2R2

X, Y=D/4
Φ: te whanui o te poka mawhiti (mm)

R pūtoro taputapu (mm)

D: taputapu diameter (mm)

Ono, te tatauranga o te nui o te rauemi
Q=(ae*ap*F)/1000
Ｑ: Te rahinga whangai (cm3/min)

ae: XY pitch (mm)

ap: Z pitch (mm)

7. Te tatau o te kai mo ia mata
Fz=hm * √(D/ap )
Fz: Whāngai whakatinana mō ia mata hm: whāngai ariā mō ia mata ap: Z pitch(mm)
D: diameter mata (mm)

8. Tikanga tukatuka mata mate
Te hohonu o te tukatuka mata tapahi = te matotoru pereti – te teitei o te mata tapahi + te pito wiri (0.3D)
D te tikanga o te diameter taputapu

9. Te tātai wā keri
T(min)=L(min)/N(rpm)*f(mm/whakamuri)
=πDL/1000vf
L: Te roa o te poka

N: Te maha o nga hurihanga

f: Whakarea rahinga whangai
D: Drill diameter

v: tere tapahi

ripanga whakarea Drill fz

0.376~0.625

10. Te tātai tātai o ngā niho ngongo
1 inihi = 25.4mm = 8 tohu

Tekau ma tahi, horsepower (gun drill)
W=Md*N/97.410
W: hiko e hiahiatia ana (KW)
Md: Toru (kg-cm)
N: te maha o nga hurihanga (rpm)

12. Ko te tātai tātai taipana e whai ake nei:
Md=1/20*f*ps*r2
Ko te f ko te reeti whangai mm/rev whakarea
r ko te pūtoro o te moka wiri (mm)
α: tapahi ōwehenga ātete ps. I roto i te kai iti, te maitai whānui ko 500kg/m㎡; ko te rino maka whanui he 300kg/m㎡;
