About the Project

Micro-cutting is increasingly used to modify the surface properties of functional surfaces as well as in the generation of mechanical systems for Micro Electro Mechanical Systems (MEMS). In the later, the quality of the generated surface can have a significant impact on the functional performance of the produced system. This is also influenced by the mechanics of deformation at the tool-workpiece interface which is related to the microcutting tool geometries and associated features. The size of the removed material during this process is in the same order as the microstructural constituents of most of metallic materials, therefore the mechanics of deformation during the chip separation and the produced surfaces are significantly affected due to this size scale. This highlights the importance of the performance of the cutting tools developed for microcutting and the interaction of the cutting edges with the deforming materials. 

Therefore, in order to develop a predictive tool to simulate material deformation as well as cutting tool interactions during microcutting, a comprehensive knowledge on mechanics of deformation during micro cutting is required to understand these interactions. This will enhance the development of new cutting tools as well as provide better prediction of functional performance in micro mechanical systems
