You are performing a machining operation that approximates orthogonal cutting. The chip thickness prior to chip formation is 19.05mm and the chip thickness after separation is 31.75mm. Suppose that the cutting force and thrust force were measured as 1595 N and 1712 N, respectively using a dynamometer. The width of the cut is 2.5 mm. The rake angle, α, is 10 degrees. Calculate the shear strength of the material in MPa.
