Machining distortion in turning caused by residual stresses

© Fraunhofer IPT

What are the mechanisms of part distortion in turning turbine discs?

Challenge and Motivation

  • Machining distortion caused by residual stresses is one of the major challenges in the manufacturing of thin-walled turbine discs made of high-temperature materials.
  • There is a lack of studies trying to quantify the influence of residual stresses on the machining distortion.


  • Analysis of the machining distortion caused by residual stresses in turning of demonstrator turbine discs.
