ABSTRACT:
Life of a tool used in a machining center having various sorts of tools can be detected by steps that a tool selection code at every execution of NC program is detected and the current-use tool number is stored, the machining distance of each tool is calculated, the machining distance is accumulated per each tool, the cumulative machining distance is compared with predetermined machining life distance to indicate the life of each tool, and then the life of each tool is determined on the basis of a result obtained in the comparing step.
