Sliding force modeling for simulation of abrasive processes
The process forces during machining with abrasives is critical for efficiency of the process and quality of the final product. The forces arise from different mechanisms like sliding, plowing and cutting. Although material removal occurs mostly by chip formation, a considerable portion of grinding energy goes to sliding between workpiece and dulled abrasive particles. This project aims to create a sliding force model to accurately predict forces with changing contact conditions in an abrasive process simulation.
Keywords: Abrasives, Machining process, Geometric simulation, Force modeling
In this project the student will create a sliding force model for a software tool simulating the kinematics and geometric interactions of an abrasive process. The new model will complement the existing force model for material removal and will link the process forces to the wear of abrasive particles. The model needs to be based on geometric properties from the interaction of abrasive grain and workpiece to capture the changes on abrasive tool during the process. Later, the student will implement the model to the simulation in Python code and test the compatibility with other models in the simulation. Finally, the code implementation will be tested for efficiency, accuracy of the results and prediction of wear behavior.
