What is Orthogonal Rake Angle?
A cutting plane is one that is perpendicular to the reference plane and contains the principal cutting edge of the turning tool. Another imaginary plane, which is perpendicular to both the reference plane and the cutting plane, is called the orthogonal plane. Therefore, the cutting plane, reference plane, and orthogonal plane are mutually perpendicular. The rake angle measured on this orthogonal plane is called the orthogonal rake angle.
How to Calculate Orthogonal Rake Angle?
Orthogonal Rake Angle calculator uses Orthogonal Rake Angle = arctan((tan(Side Rake Angle of Tool)*sin(Approach or Entering Angle))+(tan(Back Rake Angle)*cos(Approach or Entering Angle))) to calculate the Orthogonal Rake Angle, Orthogonal Rake Angle is the angle of inclination of the tool’s rake surface from the reference plane and measured on the orthogonal plane. Orthogonal Rake Angle is denoted by α symbol.
How to calculate Orthogonal Rake Angle using this online calculator? To use this online calculator for Orthogonal Rake Angle, enter Side Rake Angle of Tool (αsr), Approach or Entering Angle (λ) & Back Rake Angle (αb) and hit the calculate button. Here is how the Orthogonal Rake Angle calculation can be explained with given input values -> 2334.012 = arctan((tan(0.159926264689462)*sin(0.2617993877991))+(tan(0.635074700252309)*cos(0.2617993877991))).
