PURPOSE:To prevent uneven processing of a work and to reduce the processing time, by classifying a simultaneous processing pattern and controlling the processing start timing of each tool rest according to the simultaneous processing pattern. CONSTITUTION:The processing with turrets I 16 and II18 is started independently, the turret 16 starts processing at a time t1 of processing patterns A-F and the turret 18 is started at a time t2. A control circuit of the numerical control processing is provided with a CPU24, and a simultaneous processing pattern storage circuit 26 storing processing patterns A-F is connected to the CPU24. A stand-by signal 100 of the processing patterns E, F processed after the end of the processing patterns A-D is applied to a synchronism control circuit 28 from the circuit 26 and a delay time signal 102 is applied to a delay circuit 30. Further, the circuits 28, 30 and turret I and II shift registers 50, 52 are controlled with the CPU24 and the processing timing is processed at a logical circuit and servocontrollers 58, 60 is processed to prevent uneven processing. |
