When the internal synchronized pulse generation circuit 2 is selected in response to the operation, the numerical control device according to this embodiment is set to automatic operation mode, and the synchronization pulses supplied from the internal synchronization pulse generation circuit 2 are switched through the switching circuit. The signal is supplied to the interpolation circuit 4. The interpolation circuit 4 performs interpolation calculations in synchronization with the synchronization pulses, forms distribution pulses to be supplied to each axis (not shown) of the numerical control device based on the results, and supplies these to each axis.
