In Problem 21.1, suppose the rake angle were changed to α = 0°. Assuming that the friction-angle remains the same, determine
(a) the shear plane angle,
(b) the chip thickness, and
(c) the shear strain for the operation.
Problem 21.1
In an orthogonal cutting operation, the tool has a rake angle = 15°. The chip thickness before the cut = 0.30 mm, and the cut yields a deformed chip thick-ness = 0.65 mm. Calculate
(a) the shear plane angle and
(b) the shear strain for the operation.
