Description
Summary:The cutting temperature plays an important role in the machining process. Research on the real-time monitoring of cutting temperature and its effect on tool wear still faces many challenges. In this paper, a fiber-optic two-color pyrometer is proposed to obtain temperature of cutting edge during turning at real-time. The effects of the cutting speed, cutting depth and feed rate on the variation of cutting edge temperatures are investigated. Intermittent cutting experiments are performed to verify the effectiveness and dynamic responsiveness. The processed inserts show good durability. The cutting temperature change and its effect on tool wear are also investigated.
