Claim:
1. A power-supply management device, comprising: a power-supply-connecting/disconnecting section configured to connect/disconnect power supply to a plurality of electric-powered sections provided in a machine tool, the electric-powered sections operating in processing of a material held in the machine tool; and a comparator configured to compare a powered-on state of each electric-powered section during the processing of the material, and detect an electric-powered section which does not need to be powered-on, wherein the power-supply-connecting/disconnecting section is configured to disconnect the power supply to the electric-powered section which does not need to be powered-on during the processing of the machine tool based on information from the comparator, the comparator is configured to compare the powered-on state between synchronizations of each of the electric-powered sections in response to a detection of a synchronization command of a control program, and detect the electric-powered section which does not need to be powered-on when each of the electric-powered sections is powered-on before and after the synchronization, the comparator is configured to compare an amount of time each of the electric-powered sections has been powered-on between the synchronizations, and determine an electric-powered section, except an electric-powered section having a maximum powered-on time between the synchronizations, as an electric-powered section which does not need to be powered-on, and the power-supply-connecting/disconnecting section is configured to disconnect the power supply to the electric-powered section which does not need to be powered on after the end of an operation between the synchronizations.
