@chetan…yeah i am also doing the same…PN rao is good for manufacturing…and chetan there is one mistake in that book..average cutting shear strain = cot(shear angle)+ tan(shear angle – rake angle)….but in that book its given average cutting shear strain = cot(shear angle-rake angle)+ tan(rake angle)…so those who r studying from pn rao must note this…!!!
