Machining Friction Angle in Merchant Force Circle Formulas

Machining friction angle is termed as the angle between the tool and chip, which resists the flow of the chip along the rake face of the tool. And is denoted by β^'. Machining Friction Angle is usually measured using the Degree for Angle. Note that the value of Machining Friction Angle is always positive.
