Abstract

PURPOSE:To improve the rate of operation of a tool, by dividing tools in a magazine into plural groups, both preparing plural tools of the same kind and setting a usable time of the tool at each group, and selecting a different tool when the usable time reaches zero. CONSTITUTION:A control circuit 11 performs access of a tool usage time memory 15 in accordance with counting of a tool usage time counting timer 12, for instance, at every one minute, to read contents (tool life time) of an address, subtract 1 from its value and store the content again to said address. Simultaneously, the control circuit 11 feeds the subtraction result to a control panel control circuit 20 together with a tool-in-use/group number 14, and the control circuit 20 displays a tool number, group number and subtraction result in each display unit of a display unit 19. A life of the tool is indicated by an NC device 10, if the life is detected to 0, a tool magazine control circuit 16 drives a motor 17 to select a tool, directed by the control circuit 11, and set the tool to a main spindle.
