PURPOSE:To facilitate an easy programming job by including a new flag point instruction to an NC data and defining a unit between the NC data and the next NC data when a process operation mode is started for execution of the numerical control. CONSTITUTION:A numerical controller NC contains a processor 101, a RAM103, an operating board 105, etc. and controls a machine tool 110 via a pulse distributor 107, etc. Here a flag point instruction is put into the working program positions corresponding to the start and end points of each process together with an ON/OFF switch which allows the cycle continuation. Then this switch is set under a cycle continuation OFF state, and a process operation mode is secured. Then it is checked whether the read NC data is equal to a flag point instruction or not. If the flag point instruction is decided, an automatic operation is discontinued until a cycle start button is pushed (started) in a process operation mode. Then the next start is applied, the automatic operation is executed and stopped repetitively until the next flag point instruction is read out. |
