The present investigation was set up to examine both predicted and experimental values of forces, power, press work and friction in drawing cups from low carbon steel blanks using the same die set but in different uncoated and TiN coated conditions. The results showed a good agreement between predicted and experimental values. In addition, the findings demonstrated that the TiN coated tools reduced the friction at a tool – blank – die – interface (by about 5%), which in turn reduced the forces, power and work (by about 7%) and improved the final product quality, when compared to the performance of uncoated tools.
