Question
7.6 An orthogonal machining operation is performed on a mild steel-part 5 mm
wide. The tool cutting depth is 0.25 mm, thickness of the chip is 0.35 mm and
the tool rake angle is 10°. From a tool post dynamometer the cutting force is
measured as 1900 N. Determine the shear angle, the friction coefficient between
the chip and tool face, and estimate the shear strength of the workpiece
material.
