High temperatures during cutting have a negative effect on tool life and the condition of the workpiece. Furthermore, the monitoring of the temperatures during the cutting process poses a significant challenge. This thesis focuses on measuring the maximum chip temperature and observing the distribution of temperature on the chips using a high-speed infrared thermal camera. Additionally, it studies the formation and the shape of the chips and it investigates the effects of cutting speed and cooling methods on temperature, formation, and shape of the chips. It was observed that higher cutting speeds generally result in higher chip temperatures. In our case, the MQL technology showed poor performance compared to dry turning. The thesis also includes the analysis of chip formation, shape, and temperature distribution which was further compared to chip color.
