CNC calculi communis formula

1. Calculus functionum trigonometricarum

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

2. Calculus incisionis celeritas
Vc=(π*D*S)/1000
Vc: linea celeritas (m/min)

π: pi (3.14159)

D: instrumentum diametri (mm)
S: celeritas (rpm)

3. Calculus feed moles (F valorem)
F=S*Z*Fz
F: Pasce moles (mm/min)

S: celeritas (rpm)

Z: foliorum numerus
Fz: (re feed per ora)

4. Calculus de residua materia altitudinis
Scallop=(ae*ae)/8R
Scallop: materia altitudo RELICTUM (mm)

ae: XY picis (mm).

R instrumentum radii (mm)

5. Calculus materialium effugium foraminis
Φ=√2R2

X, Y=D/4
Φ: diametri effugium (mm)

R instrumentum radii (mm)

D: instrumentum diametri (mm)

Sex, calculus materiae
Q=(ae*ap*F)/1000
Ｑ: Pasce moles (cm3/min)

ae: XY picis (mm).

ap: Z picis (mm).

7. Calculus feed per ferrum
Fz=hm * √(D/ap )
Fz: Implemented feed per ferrum hm: Theoretical feed per ferrum ap: Z pice (mm)
D: diametri lamina (mm)

8. Die ore processus modum
Agmen processus profundum = lamina crassitudine - acies altitudinis + terebro tip (0.3D)
D instrumentum diam

9. EXERCITATIO tempus formulae
T(min)=L(min)/N(rpm)*f(mm/rev)
= πDL/1000vf
L: foramen longitudinis

N: Number revolutionum

f: Pasce moles coefficientis

10. Formulae calculi tubi dentium
1 inch = 25.4mm = 8 puncta

XI, horsepower (gun terebro)
W=Md*N/97.410
W: potentia requiritur (KW)
Md: Torque (kg-cm)
N: revolutionum numerus (rpm)

12. Aureus calculi formula talis est;
Md=1/20*f*ps*r2
fis est feed rate mm/rev coefficiens
r est aliquantulus radii terebro (mm)
α : secans resistentiam proportionis ps.In parvis pascuis, chalybs generalis 500kg/m㎡ est;ferrum emissum generale est 300kg/m㎡;
