Abstract

The present work investigates the characteristics of aluminium alloy 6061-T6 in the microcutting process of single point diamond turning. The machined surface and chips are studied based on the back-scattered election (BSE) images captured by scanning electron microscope (SEM). The characteristics can be identified as the grey specks and black pits residing in both chips and machined surface. A two-dimensional thermo-mechanical coupled finite element model is proposed to estimate the heat generation during the microcutting process. An analysis indicates that the characteristic specks and pits are induced by the elevated temperature incurred by plastic work and friction from the tool-work interaction.
