Abstract:
Net power consumed by one or more tools, continuously or intermittently is totalized and compared with a predetermined energy limit characterizing the life expectancy of a tool for optimum and safe use on a machine tool. Digital and computer techniques are used in order to keep track of the usage of the various tools within their respective life expectancies.
