PROBLEM TO BE SOLVED: To provide a numerical value control device capable of continuing a processing operation immediately before specified time when time for stopping the processing operation is specified.SOLUTION: The numerical value control device includes a stop time input unit for receiving specified time, a processing time prediction unit for predicting the processing time of a processing program in view of the block execution order of the processing program and the acceleration/deceleration time of the drive unit of a machine, an operation stop block specification unit for predicting the stop time execution block of the processing program predicted to be engaged in execution at the specified time based on the processing time for each block of the processing program predicted by the processing time prediction unit and capable of safely stopping the processing operation in the reverse order of the block execution order from the stop time execution block, and a program operation control unit for executing control to stop the processing operation at the stop block specified by the operation stop block specification unit.SELECTED DRAWING: Figure 2 |
