Friction drilling process is a circular hole making in a sheet materials. It is a novel method using the principle of hot forming. The process involves penetrate a rotating conical tool through a sheet metal work piece. The heat generated from the frictional force due to axial and rotational forces between the interface of tool and work piece. Is to soften the work piece material, causing that tool to penetrate and deform the work material in to bushing shape in a single step without generating chips. In this paper investigates large Elastic strain, stress and work material deformation in friction drilling. The friction drilling process will develop high temperatures and deformation of the work material is very high. Which are difficult to measure experimentally. So, modeling and simulation is a necessary tool to understand the material flow. In which explicit dynamic analysis of a friction drilling with HSS, Tungsten (WC) tools and A7075-T6 as work piece is done using Ansys work bench. The modeling of the friction drilling tools and work piece will develop in PRO/E. The simulation of the friction drilling is used to analyze the stress, strain and deformation of the work piece.
