A study of turbomachinery components machining and repairing methodologies

Purpose This paper discusses research on machining and repairing of turbomachinery components which are generally complex geometries and made up of difficult to machine materials (nickel super alloys or titanium alloys). Design/methodology/approach The approaches, methods and methodologies used for machining and repairing of blades are reviewed as well as the comparisons between them are made. Findings Particularly, the most recent blade machining and repair techniques using high flexible machine tools and industrial robots, are mentioned. Practical implications The limitation of the approaches, methods and methodologies are given and supported by real practical application examples. Originality/value This paper presents a state of the art review of research in machining and repairing of turbomachinery components, which have been mainly done in the last decade. The paper act as a reference, gathering the works about turbomachinery components from a manufacturing point of view.
