Alternative Machining Processes for Disk Roughing
Which machining strategy is the most suitable for roughing profiled grooves in turbine disks?
Challenge and Motivation
- Broaching with high speed steel is still state of the art for roughing and finishing of fir-trees and dovetails into turbine disks.
- Disadvantages of the broaching process are high tool costs, special machine tools and inflexible slot geometries.
- Identification of alternative processes for roughing of profiled grooves.
- Technical and economic evaluation of the strategies.
