Question

If the principal cutting edge angle, the orthogonal rake and the inclination angle are known

Answer 1

Orthogonal Rake Angle (γO)—It is the angle of orientation of tool's rake surface from the reference plane (πR) and measured on orthogonal plane (πO). Inclination Angle (λ)—It is the angle of inclinationof tool's principal cutting edge from the reference plane (πR) and measured on cutting plane (πC).
