PURPOSE:To read out time data of operation and working of a machine tool in accordance with a sequence program of a PC by adding a present time memory and an interval timer. CONSTITUTION:When the machine tool is operated in the memory mode, a present time memory 5 receives the start ime of memory mode operation from an interval memory 3 and stores it is an STM. When the program of memory mode operated is terminated, the machine tool terminates the memory mode operation, and the present time memory 5 receives the end time from the interval timer 3 and stores it, and a CPU1 subtracts the time stored in the STM from the end time, and operated time data is stored in the present time memory 5 as an SAM1. When the program of operation is continued in the memory mode furthermore, the operation start time and the end time are stored in the present time memory 5 similarly, and the subtraction is performed by the CPU1, and the result is added to the SAM1 stored already in the memory to obtain an integral value. This value is read out properly. |
