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.

Objective

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