PURPOSE:To enhance the activity rate of machinary and as well to obtain a stable machining accuracy, by automatically carrying out refusing operation and run-in operation during the period until starting of the next machining operation after completion of the present machining operation, and as well by lasting the run-in operation until starting of the next machining operation. CONSTITUTION:When an unmanned operation switch is turned on in order to turn into a night-time unmanned machining operation from a day-time machining operation, data from an input circuit 53 are calculated in a CPU 54, and a value on a memory 55 is delivered to an output circuit 57 to display an integrated time on a display counter. Since an NC starting button is operated, the CPU 54 counts time in association with a clock-input circuit 56 when it is the time for initiating the night machining operation, and stores the counted value into the memory 55. Simultaneously, the value in the memory 55 is delivered to the circuit 57 to display the integrated time on the display counter. Further, the machining is progressed while date on a paper tape is decoded, and when a completion signal is decoded, the NC starting button is turned off so that a refusing operation program on the paper tape is carried out. Then, the run-in operation is carried out. |
