Technological and Operational Aspects of Integrated Bladed Rotors Manufacture

摘要

This paper examines technological and operational aspects that influence the selection of manufacturing process structure for integrated bladed rotors. On one hand the choice of rough manufacturing process technologies is highly important as it determines the main portion of the cycle time and as a result greatly affects the overall unit cost. On the other hand the finishing processes greatly influences the operational parameters of the blisk in service as the final geometry, surface roughness and boundary layer properties are formed at this stage. This research provides ways to build a solid framework for selecting optimal technologies and tools at each stage of blisk manufacturing based on a set of key parameters that include geometric requirements specified by the drawings, properties of the stock material, production volume and operational requirements.
