Analysis of most competitive process for manufacturing of sealing slots (ECM)
What are the technical capabilities of ECM for manufacturing sealing slots?
Challenge and Motivation
- State of the art manufacturing process: Sinking EDM
- Advantage: High machining accuracy
- Disadvantages: Thermal process, detrimental surface integrity and low material removal rate
- ECM is characterized by high removal rates and achieving a very good surface integrity
Objective
- Investigation of the suitability of ECM to produce sealing slots made of Ni-based alloy.
