In this work, temperature distribution of aluminium alloy (Al 6061-T6) during the cold forging process is studied with the support of inverse analysis. The values of friction at die-work interface, Taylor-Quinney coefficient and interface heat transfer coefficient (IHTC) are estimated using the inverse method with the help of finite element method (FEM) and experiments on a cylindrical specimen. These values are used to predict the temperature distributions during forging of workpieces of different geometries i.e., hollow cylinder and frustum of cone specimens. Taylor-Quinney coefficient may differ considerably depending on the material and processing condition. Hence, it is recommended to obtain the proper value from an inverse procedure as proposed in this work. Transient analysis of a frustum of cone specimen during the cold forging process is carried out and the temperature contours are presented. A good agreement is seen between the FEM simulation and experimental results.
