Development of a hybrid modeling for the analysis of the coating influence on machining process
Abstract
The wear resistance of cutting tools has been often enhanced using single or multilayered coatings on their surface. During machining processes, the extreme thermomechanical loading which generated at the tool–chip interface greatly affects the cutting tool zone. The study of the coating behaviour leads to a better understanding of its impact on the overall structure. For this purpose, the MAX-FEM model has been extended in order to describe the behaviour of such structures, ensuring accurate results without special mesh refinement. The ability of the proposed numerical scheme is demonstrated by solving a 2D heat conduction problem. The effectiveness of the model has been tested in terms of convergence and computational time, and systematically compared to a classical finite elements solution. A discussion about the model limitations was also made.
