Tool Wear Assessment on Turning Operation by 2D Finite Element Simulation

Tool wear is a critical problem in industrial manufacturing. When tool wear reaches a certain value, it causes a change in the tool geometry. This directly affects the chip formation, cutting force, temperature distribution, machining quality etc. Therefore, prediction of tool wear is of great importance for optimizing the cutting process. In this study, 2D finite element simulation is presented for chip formation analysis considering thermal effects. Boundary conditions are defined as stationary for the workpiece and axial velocity to the tool at cutting direction. Different models are analyzed by changing the tool geometry and the results of the tool wear are discussed.
