ABSTRACT:
In a numerical control machine tool, the time that the tool or bit actually operates is counted in the control device of the numerical control system. The present time control data collection system comprises a data memory having a plurality of flags, the condition of each of which reflects the actual operation of the related tool or bit, a real time clock which provides signals at predetermined intervals, and means for counting the real time clock on the condition that the particular flag in said memory is on. The counted value is displayed either directly, or the fact that the counted value exceeds the predetermined reference value is indicated. The present system can also be implemented using a programmed micro-computer.
