The purpose of MGIMS project is to develop and test thin film microsensors for temperature, tool wear and heat flux measurements in machining processes (grinding, turning). Our objective is to have a deep insight on the temperature distribution at micrometric and submicrometric levels so it is necessary to be as close as possible to the interface. Moreover, it is necessary to quantify the wear due to the material removal process and then accurately localize the new formed interface between the worn surface of the tool and the workpiece. For this purpose, temperature and wear sensors at microscale have to be used in parallel because one needs to quantify simultaneously the temperature and the reduction of the cutting edge. Thin films micro sensors are a good solution for such problem as they 1) thanks to their low dimensions allow to obtain measurements very close to the interface and to understand tool-workpiece interactions, 2) are reusable when the cutting edge is reduced thanks to the possibility of multiplying the number of sensors and optimizing their location on the cutting edge, 3) reduce the intrusive nature of sensors and 4) make their production noticeably easier.
