Detection of Roughing Tool Defects in Broaching of Fir-Tree Slots for Aerospace Engines Using Process Monitoring Systems

Fir-tree slots provide the form-fit connection between turbine disks and blades in aerospace engines and therefore constitute highly stressed geometries in safety-critical components. These slots are manufactured by broaching, a machining process performed near the end of the manufacturing chain for turbine disks made...
