Development of an Advanced Machine Tool for Combined Forming-Strengthening Process for Production of Load Bearing Aircraft Panels

Article Preview

Abstract:

This paper presents the development of a machine tool which combines the forming and the surface strengthening processes for large scale aircraft parts together. The developed machine tool produces the required part shape not by bending but by combination of differential compressive plastic stresses induced by shot peening to different areas of the part in a predetermined sequence. It has a total mass under 4200kg and is capable of forming and strengthening panels of 15x1.5x0.02m3 in size. The machine tool has been successfully applied for production of honeycomb wing panels of Be-200 multipurpose amphibious aircraft made of aluminum alloy.
