In-Process Deformation Measurement of Thin-walled Workpieces

During the finish milling process of thin-walled workpieces, deformations occur due to the mechanical and thermal influences. The measuring method outlined in this publication allows an accurate assignment of these deformations to their respective cause in size and form, due to the high temporal and spatial resolution of the used optical measurement system. Furthermore, dividing the dis-placement into its mechanical and thermal proportion allows a fully decoupled validation of process models. Especially the simula-tion results of thermal models, which are mainly validated by measured temperature fields, can be further ensured.
