Consider the following statements with respect to the relief angle of cutting tool: 1. This affects the direction of chip flow. 2. This reduces excessive friction between the tool and workpiece 3. This affects tool life 4. This allows better access of coolant at the tool workpiece interface Which of the statements given above are correct?

Linked Data: In a orthogonal cutting experiment, an HSS tool having the following tool signature in the orthogonal reference system (ORS) has been used : 0−10−7−710−75−1 Given: Width of cut =3.6mm Shear strength of workpiece material =460N/mm2; Depth of cut =0.25mm Coefficient of friction at chip tool interface =0.7 Minimum power requirement (in kW) at a cutting speed of 150m/mm is
