Minimum shear strain in turning with a zero orthogonal rake angle cutter
Question: Determine the theoretically minimum possible shear strain in orthogonal turning with a cutting tool of zero orthogonal rake angle. [ESE 2009] Solution: Metal cutting processes are employed to remove excess material from workpiece to impart desired shape and finish. This material removal takes place by shearing when a wedge shaped cutting tool compresses a layer of workpiece material. The cutting strain developed due to shearing is termed as shear
