1) In an orthogonal cutting operation, the cutting tool has a rake angle = 15°. The chip thickness
before the cut = 0.20 mm and the chip thickness after the cut tc = 0.8 mm. If the cutting
force and thrust force are measured during an orthogonal cutting operation with values, Fc =
2000 N and Ft = 1890 N. The width of the orthogonal cutting operation w = 2.5 mm.
Determine:
The Shear Angle
The Shear Strain
The Shear Strength of the material
The Force of Friction
The friction angle
