Abstract
A computer-numerically-controlled (CNC) machine is configured to (i) measure a power of a beam of electromagnetic energy at a location between a source of the electromagnetic energy and a destination in the CNC machine, the beam of electromagnetic energy traveling from the source to the destination being susceptible to one or more interferences, and the one or more interferences being capable of altering the power of the beam of electromagnetic energy by at least diverting, away from an intended path for the beam of electromagnetic energy, at least a portion of the beam of electromagnetic energy, (ii) detect, based at least on the measured power of the beam of electromagnetic energy being less than a threshold value, an interference of the beam of electromagnetic energy, and (iii) in response to detecting the interference of the beam of electromagnetic energy, perform one or more actions.
