(USCS units) A turning operation is performed using a rake angle of 15°. Cutting speed = 200 ft/min, feed= 0.012 in/rev, and depth of cut = 0.100 in. The chip thickness ratio measured after the cut = 0.48.

Low carbon steel having a tensile strength of 450 MPa and a shear strength of 270 MPa is cut in a turning operation with a cutting speed of 2500 mm/s. The feed is 0.15 mm/rev, and the depth of cut is 0.25 cm. The rake angle of the tool is 12° in the direction of chip flow. The resulting chip ratio is 0.55.
