Alternative Process Chains for Profiled-Slot Manufacturing

© WZL der RWTH Aachen

Which potential can be achieved in identified process chains for Profiled Slot Manufacturing?


Challenge and Motivation

  • Broaching with high speed steel is still state of the art for finishing of fir-trees and dovetails in turbine disks.
  • Disadvantages of the broaching process are high tool costs, special machine tools and inflexible slot geometries.


  • Identification of alternative processes for finishing of profiled grooves.
  • Technical and economic evaluation of the strategies and the process chains.
