The word “sensor” typically refers to a device that converts a change in a physical stimulus into output parameters that can be read by human or an electronic instrument. As an example, a thermocouple that converts the difference in temperature at a reference point and the measurement point into an electrical voltage forms a temperature sensor. The output of a sensor contains information about the state of a physical object (e.g., a machine tool) or a process (e.g., metal forming). Such information can be processed for improved observability in manufacturing machines and processes (Dornfeld 1992; Altintas and Park 2004; Gao et al. 2008; Altintas and Jin 2011), leading to better control and decision-making (Toenshoff and Inasaki 2000).
With the advancement of microelectronics and information technology over the past decades, the definition of “sensor” has been broadened by including the concept of “sensor nodes” or “sensing...
