During turning a steel round of 160 mm diameter at 560 rpm employing a feed of 0.32 mm/rev and depth of cut as 4 mm by a ceramic insert having nomenclature 0, -10, 6, 6, 15, 75, 0 (mm), the following observation were made. Cutting force 1600 N, Thrust force = 828 N and chip thickness= 1 mm Using merchant circle Diagram (MCD), compute: (i) Friction force on tool rake face and corresponding normal reaction, (ii) Shear force and corresponding normal face, (iii) Co- efficient of friction between tool-chip inter faces, (iv) Cutting power and specific cutting 10 energy.
