Surface Integrity – Consideration of further manufacturing processes (milling & grinding)

How to achieve a standardized evaluation of surface integrity for different machining processes?

Challenge and Motivation

  • Surface integrity parameters determine functionality and life cycle of turbomachinery components.
  • The final surface rim zone is affected by each machining step along the manufacturing process chain.


  • Extension of the database with further experimental results.
  • Analysis of the main drivers for generating the required rim-zone quality.
