PURPOSE:To require no spare tool of the same shape and size as a standard tool and to require no special auxiliary unit by storing in memory the inherent tool correction data on all tools including spare tools respectively in a numerically controlled unit. CONSTITUTION:A machine tool control unit 2 is operated to control a machine tool by receiving the data of a numerically controlled paper tape 1a of a numerically controlled unit 1. Various programs for operating the machine tool is stored in the tape 1a, and designation of tools and correction of tool sizes have been programmed. A tool life monitoring unit 3 checks the usage time of tools after receiving a tool number signal S1 from the unit, and outputs a tool number signal S2, the unit 2 outputs a completion signal to the tool life monitoring unit 3, then the unit 1 reads out and executes the next block of the program after receiving a completion signal S4 from the unit 3. |
