Orthogonal cutting is a type of metal cutting in which the cutting edge of the wedge-shaped cutting tool is perpendicular to the direction of tool motion.
Friction force is given as, F = Fc sinα + Ft cosα
Normal force is given as, N = Fc cos α – Ft sin α
Shear Force is given as, Fs = Fc cos ϕ - FT sin ϕ
Calculation:
GIven:
Rake angle (α) = 0°, Fc = 500 N, Ft = 250 N
F = Fc sinα + Ft cosα
F = 500 sin0 + 250 cos0 = 250 N
N = Fc cos α – Ft sin α = 500 cos 0 = 500 N
Coefficient of friction (μ) = F/N = 250/500 = 0.5Last updated on Jun 13, 2025
