Analysis of Part Distortion due to Residual Stress in Milling (study)

© Fraunhofer IPT

How can part distortion of a thin-walled component be analyzed during milling?


Challenge and Motivation

  • Residual stresses can lead to significant dimensional errors through part distortion.
  • A study by Boeing, based on four aircraft programs, estimated the rework and scrap costs related to parts distortion comes to in excess of 290 million dollars.


  • Identification of common methods to analyze part distortion due to residual stress in milling.
  • Experimental demonstration of part distortion during milling.
  • Modelling and simulation of part distortion in milling.
