摘要： A data input-output device for an interactive numerical controller includes a key board having a set of numerical keys arranged to input data used for machining operations of a machine tool into a memory device, a first group of selection keys in the form of normal operation keys arranged to correct the input data in accordance with a workpiece to be machined, a second group of selection keys in the form of set-up change keys arranged to change process management data of the machining operations, a mode switch arranged to instruct the operation of the numerical controller, and a permission switch arranged to be turned on only by using an authorized key, and a central processing unit programmed to disable data input by manipulation of the second group of selection keys in a condition where the first group of selection keys is being manipulated and to permit the data input by manipulation of the second group of selection keys in a condition where the permission switch is turned on after the mode switch has been set in an input position under an inoperative condition of the first group of selection keys.
