Authors Axel Friese, Jurgen Lohmar, Frank Wustefeld Kugelstrahlzentrum Aachen GmbH, Aachen, Germany Introduction Shot peen forming is above all carried out in the aeronautic and aerospace industry for the production of complex integral structures in fuselage and wing components (= Partial Forging Process / Shot as a Tool). Particularly in the aeronautics industry, development engineers and designers intensively work on complex, single-axis or multiple-axis curved geometries, varying panel thicknesses and/or stringer stiffenings. The aim here is to optimize weight and hence to save on aircraft operating costs, as well as to optimize production processes (= Design for Manufacturing Feasibility). A further important customer requirement comes from production managers: completely controlled, documented and reproducible processes with practical flexibility in design are a prerequisite for the industrial series production of carrier rocket structures or airplane components such as fuselage and wing panels (= State-of-the-art Industrial Processes). Appropriate documentation for today's market should include the component data and the influences of forming on the material as well as all process data relevant to the customer (= Complete Transparency and Constant Quality Control). The KSA - Kugelstrahlzentrum Aachen GmbH (Aachen Shot Peening Centre) uses modern modelling and facility technologies which facilitate controlled shot peening with complete process control and automation (= KSA - Controlled Shot Peening). The following describes the procedure for implementing controlled shot peening. We will use examples from our current work to show that this highly-automated process can be employed both for producing components on a contract basis as well as for series production at the customer's own plant.
