Evaluation of traditional and additive manufacturing methods of centrifugal pump casing with regard to circular economy

Abstract

This thesis examines the integration of high-speed machining (HSM) and additive manufacturing (AM) technologies in the production of industrial pump components, with a specific focus on the DCN-19Е centrifugal pump casing. The work presents a detailed comparison of these manufacturing methods in the context of the Circular Economy (CE), emphasising sustainability and efficiency. Key aspects include the optimisation of machining processes, toolpath generation and the use of advanced CAM systems such as Autodesk Fusion and Netfabb. The study highlights the potential of AM for rapid prototyping and low-volume production, while also addressing the limitations of each method in terms of energy consumption, material waste and economic viability. The findings contribute to the wider discourse on sustainable manufacturing practices and provide insights into the practical applications and performance evaluation of HSM and AM in the context of modern industrial production.
