ICTM Aachen – International Center for Turbomachinery ManufacturingMachining distortion in turning caused by residual stresses
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.
Objective
- Analysis of the machining distortion caused by residual stresses in turning of demonstrator turbine discs.
