Abstract

This paper is focused on the prediction of tool wear in turning. More in detail both 2D and 3D numerical simulations were performed in order to compare the numerical predictions with reliable data from experimental tests. The latter were carried out in orthogonal cutting conditions machining disks of AISI 1020 mild steel with uncoated carbide tools. The results showed a good agreement between the already assessed 2D simulation, the novel 3D simulative models and the experiments. As a consequence, a new strategy in cutting investigations could be made of different subsequent numerical phases: 2D analysis could be used in order to set up reliable models based on orthogonal cutting and, furthermore, fully 3D applications could be extended to real and complex cases.
