Large deformation is a major deformation operation in many metal-forming processes, such as forging, rolling, extrusion, stamping and fine-blanking. It is difficult to study the deformation changes in these processes in a practical way, through the measurement of forces, due to the severe and localized nature of plastic deformation such as in the fine-blanking operation. Therefore, the forces analysis of most metal-forming processes cannot be carried out successfully by experiments. Thus, this paper aims to present the development of an effective process of forces measurement in fine-blanking process. Also, the effect of blank geometry and material properties on forming force in fine-blanking process was studied by theoretical formulation and experimental approach. Tensile strength and initial blank thickness were considered in this research. The obtained results indicated that by increasing the initial blank thickness and the tensile strength, the forces in fine-blanking process is increased.
