Abstract
This work focuses on the prediction of phase transformations and shape deviations for drilling of demonstrator workpieces. In a first step, a 2D chip formation simulation was developed with all physical effects. Based on this simulation a simplified workpiece geometry with only one drilling hole was 3D modeled and tested for its predictive capability of phase transformations and shape deviations. Therefore, the feed rate, the rotation of the drilling tool and the material removal were considered for the process kinematics. Using these results the modeling approach was optimized and transferred into a simulation model with a demonstrator workpiece to minimize shape deviations and control phase transformations using different compensation strategies. The simulations were validated by experiments.
