ABSTRACT
In high-precision product industries, controlling residual stress-induced distortions in large, thin-walled components is critical in order to produce high-quality light-weight components. Understanding the residual stress history is key to deal with this problem. In this study, the residual stress history from start to end of multi-step machining is measured and investigated in order to better understand the influence of machining strategies on the part distortions. The multi-step machining process is utilized to investigate the relation between residual stress history, the machininginduced residual stress and the part distortion. An analytical model is used for reference and comparison with experiments. The experimental work is performed using multi-step milling process as experimental set-up, X-Ray diffraction to measure residual stresses, and CMM to measure the profile and the distortion of the thin structure.
