Handling special alloys in cutting operations is a demanding task due to the heat generated during the process. High temperature induces stresses on the tool which is the main cause of tool failure and the production of scrap parts. To assess and overcome this major issue, project Sm@rtEdge aims to develop a sensor for continuous monitoring of the temperature on the tool cutting edge during machine operations. A solution that allows process optimization trough increase tool lifetime and scrap reduction, by performing cutting operations within the correct temperature range, in order to improve the sustainability of the process on the machinability of special/hard-to-machine alloys.
MAIN OBJECTIVE: To strengthen research, technological development and innovation.
Development and design of a wear resistant thin film sensor for smart monitoring of machining operations, in-situ. The goal is to achieve a continuous wireless monitoring of the temperature during a machining operation with a sensor system deposited on the cutting edge of the tool which have dielectric, sensor and wear resistant properties.
Integration of a new PVD nitride multilayer system with the cutting tool allows the evaluation of the temperature on cutting edge up to 900ºC, maintaining structural and mechanical properties at high temperatures, which combined with wireless data transmission, is a breakthrough for smart machining and autonomous production.
