Novel Approach for 3D Simulation of a Cutting Process with Adaptive Remeshing Technique

This paper presents an approach of a 3D cutting simulation with a continuous adaptive remeshing technique. Such a method allows the investigation of cutting processes without losing precious information. Furthermore, the developed 3D remeshing technique represents a possibility to investigate the effects caused by the secondary cutting edge in detail for more complex cutting processes. When a 3D model is builtup to simulate the cutting process, an accurate meshing of the workpiece and the cutting edge is applied, which means that a large number of elements is generated. The presented remeshing method is applied only locally at regions, where distorted elements are located. This leads to a significant reduction of the calculation times compared to other remeshing techniques.
