As machining speed is increased and processing time is decreased, transient or instantaneous power measurement has become necessary. Instantaneous power must be measured by measuring the voltage and current of a balanced three-phase alternating-current power supply directly. Taking a moving average before power calculation can provide power waveforms less affected by measurement noise even in machines incorporating inverter control. This paper introduces an appropriate instantaneous power measuring method and a data processing method by showing examples in which these methods were successfully applied to drilling.
