In an orthogonal turning operation, it has been observed that the friction force acting at the chip tool interface. is 402.5 N and friction force is also perpendicular to the cutting velocity vector. The feed velocity is negligibly small which respect to cutting velocity The ratio of friction force to normal, force is 1. The uncut chip thickness is 0.2 mm and chip thickness is 0.4 mm and the cutting velocity is 2 m/s. Find the rate of heat generation at the primary shear plane in watts [up to 1 decimal place]
