Optimized Blisk Series Production by Use of Tool Path Compensation Methods

© Fraunhofer IPT

Do tool path compensation methods improve product quality and process stability in Blisk production?


Challenge and Motivation

  • Many different influences such as wear, tool and workpiece deflection cause geometric form errors during milling.
  • These geometrical errors reduce the process capability and lead to tolerance violations.


  • Application of cutting simulation to compensate geometrical deviations in the process planning.
  • Evaluation of the method in the use case of 5-axis milling of downscaled Blisk’s.
