CNC Knowledge: The triangle functions which must be included by digital control must be understood

Doing CNC is more or less, and the drawing is incomplete. , brothers who cannot learn well.

The relationship between the angle function

(Sinoid) sin θ = bate A / Linging C

(Yu xian) cosθ = neighbor b / linging c

(Positive cut) tanθ = concrete a / neighbor B

Passion A = Linging C * Sinθ

Better a = neighbor b * tanθ

Quartier B = Linging C * Cosθ

B = Division A / Tanθ neighbor

Landscape C = Division A / Sinθ

Landscape C = district b / cosθ

Example: known as oblique edge c = 20, angle θ = 35 degrees, see opposite A and neighbor B

Passion -Edge A = slope edge c * sinθ = 20 * sin (35) = 20 * 0.573576 = 11.471

Quartier B = Lingcie C * cosθ = 20 * cos (35) = 20 * 0.81915 = 16.383

The relationship between the conicity of the tower and the function of the triangle

Piccorcinity ratio t = (large diameter d-divide d) / (length l)

Tanθ = (large diameter d-small diameter d) / (2 * length l)

D = D + 2 * L * Tanθ

D = D – 2 * L * Tanθ

θ = tan – ((dd) / 2l)
