A method and apparatus for monitoring the useful life of machine tools. A controller continuously monitors the amount of time a particular tool has been used as well as the materials the tool has been used to machine. A useful lifetime of the tool is estimated based on the characteristics of the tool. When the amount of time the tool has been used, adjusted based on the materials used, reaches the useful life span of the tool, the controller directs the machine to remove the tool from service and retrieve a duplicate tool for further machine operations.
