IBRs are typically machined using High-Temperature Alloys or Titanium. IBR ( Integrally Bladed Rotor) or blisk, is a component comprising both rotor disk and blades. It consists of a single part, instead of an assembly of a disk and individual, removable blades to increase the power density and performance of the engine. Since the 1980’s, its use has continuously increased in major applications for both compressors and fan blade rotors. IBRs can be produced with several different manufacturing processes, including CNC milling. The measurement and inspection of IBRs is crucial for guaranteeing engine performance and safety and are carried out at the end of the manufacturing process. Usually, IBRs are produced from hard-to-cut titanium (Ti) or nickel-based alloys (Ni-alloys) and the milling cutters used need to meet stringent productive machining requirements
