Following data were collected from an orthogonal machining test on steel:
Cutting speed = 18 meters / minute
Rake angle = 20 degrees
Clearance angle = 10 degrees
Width of cut = 3.2 mm
Un-deformed chip thickness = 0.10 mm
Deformed chip thickness = 0.25 mm
Cutting force in the cutting velocity direction = 80 kgf
Normal force in a direction normal to cutting velocity = 50 kgf
Draw the circle diagram of force and evaluate the following:
Shear angle; Shear strain; Friction co-efficient against chip flow; Friction force on the rake face.
