Abstract: An NC lathe includes an energization signal switching unit for switching an energization signal set for each electric device between an energization required state and an energization non-required state, a prohibition signal switching unit for switching an energization prohibition signal set for each electric device between a prohibited state and a permitted state, a signal determination unit that determines whether or not each electric device is in a power saving state in which the energization signal for the electric device is in the energization required state and the energization prohibition signal is in the prohibited state, and a saving calculation unit that determines a cumulative duration of the power saving state, computes a device-specific power saving for each electric device on the basis of the cumulative duration, and calculates a power saving by adding together the device-specific power savings.
