Our proposed technique can potentially be used to optimize any drilling process, requiring the use of small drill bits, through direct temperature measurement at the drill bit instead of relying on indirect parameters (speed of rotation, applied force) in order to avoid an overheating as it is currently done nowadays.Temperature monitoringdrill bitsynchronous detectionfibre Bragg gratingtext::conference output::conference proceedings::conference paper
