This study presents an in-process analysis of strain rate and strain in the primary shear zone using high speed Digital Image Correlation (DIC) techniques. The comparison between measured and computed results demonstrates the suitability of DIC techniques and the robustness of the modeling approaches.
In the last eight decades, considerable modelling and computational efforts have been made to predict the strain rate during cutting with the aim of optimizing machining processes. However, the validation of these modelling approaches on a local scale remains excessively limited due to the lack of in-situ measurements and the faulty existing quick-stop tests. This work presents the in-process analysis of the strain rate and strain in the primary shear zone using high speed Digital Image Correlation (DIC) techniques. The comparison of measured and computed results shows the suitability of the DIC techniques and the robustness of the modelling approaches. (c) 2021 CIRP. Published by Elsevier Ltd.
