Abstract:
In the scope of Industry 5.0 applied to the cutting tools industry, the advent of smart cutting tools consisting in the integration of sensors in cutting tools to monitor, and thus help control and adjust in real time different aspects of a machining process, arises as a unique opportunity to achieve unprecedent levels of operational efficiency and productivity. Therefore, this work focuses on the incorporation of temperature sensors in WC-Co cutting tools for measuring cutting temperature, through the fabrication of 3D printed K-type embedded thermocouples by multi-material laser powder bed fusion. The thermocouples powder composition was prepared through high-energy ball milling and properly characterized to guarantee the characteristics for laser powder bed fusion. Validation in an industrial environment during turning of different alloys revealed that the developed 3D printed embedded thermocouples can measure precisely and accurately cutting temperature in real time, as well as withstand the demanding turning process.
