“…According to the smart machining-monitoring technologies provided by leading machining companies [ 9 , 10 , 11 , 12 ], monitoring of milling-processes and cutter-conditions (such as cutter-wear conditions and cutter-breaking occurrence) can produce many significant benefits such as improving machining automation, preventing machining failures, decreasing machine downtime, and reducing maintenance costs. More recently, wireless sensing technology has been widely used in industrial and medical applications [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Specifically for the machining and manufacturing industries, researchers have demonstrated novel wireless sensing applications for real-time machining monitoring [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ].…”
