In an orthogonal cutting operation, the 0.250 in wide tool has a rake angle of 6 degrees. The lathe is set so the chip thickness before the cut is 0.011 in. After the cut,t he deformed chip thickness is measured to be 0.027 in. Calculate (a) the shear plane angle and (b) the shear strain for the operation. I really dont know where to begin other then to say I am now neck deep in a class that had no math prerequisite. I dont have much math knowledge beyond minor algebra. Even with the help of the tutoring center here in my university and living with the book in front of my face I really dont understand what I am supposed to be doing here.
