Edge Finishing of Large Turbine Casings Using Defined Multiedge And Abrasive Tools In Automated Cells

Abstract

Abstract Automate finishing processes is a global challenge in several industrial sectors. Concretely, when dealing with aero-engine components, only simple finishing processes were automated nowadays. Most of the high-added value components manufactured are finished hand working, using deburring and polishing manual techniques. The driver of the proposed work is to achieve the necessary knowledge to introduce in a production line a complete and finishing process for automated robotic deburring applications with low machinability materials (Inconel 718 in the case of study) on aero-engine casings with complex geometries: extruded casting bosses, internal features, etc. For this purpose, a three-step methodology is presented and analysed, providing a feasible workflow combining multi-edge solid tools and flexible abrasive tools to automate finishing operations taking account all the process drawbacks and peculiarities. Results show that using the correct techniques, processes and parameters, an automated finishing process that reduces operating time can be implemented in production lines.
