Visualizations from A Mesh-Free Multi-Physics Approach to Modeling Deep-Hole Drilling and Predicting Chip Jamming and Drill Failure

The related dissertation introduces a novel mesh-free multi-physics modeling approach that couples Smoothed Particle Hydrodynamics (SPH) and the Discrete Element Method to simulate transient chip evacuation and investigate failure mechanisms such as chip jamming and drill breakage.

This modeling approach enables the detailed representation of dynamic interfaces and boundary conditions inherent in DHD, which are otherwise difficult to capture using traditional mesh-based methods. Video Context The presented mesh-free modeling approach allows the transient investigation of the chip evacuation in DHD. The dissertation demonstrates the approach capabilities for investigating the impact of drill geometry, metalworking fluid (MWF) characteristics, borehole filling states, and MWF supply levels on the chip evacuation efficiency.
