    • A numerical control apparatus enables a tool to move parallel or vertical to a designated shape to easily carry out a machining of a prototype using general-purpose machine tools. A graphic storing device displays guidance information on a display unit through a graphic control circuit and also stores a designated shape such as an oblique straight line or a circular arc entered by the operator through a keyboard in an interactive fashion. On the detection of a pulse signal HP from a manual pulse generator, an interpolation device reads a changeover signal H/V for commanding one of the parallel movement or the vertical movement of the tool from a changeover device. Then, the interpolation device outputs an interpolated pulse signal CP corresponding to the pulse signal HP and changeover signal H/V in accordance with the designated shape stored in the graphic storing device and supplies the interpolated pulse signal HP to an axis control circuit.

    • A numerical control apparatus in which tool feed can be stopped at the same time as machining is completed. An interpolating device in a numerical control apparatus interpolates a pulse signal HP supplied from a manual pulse generator and outputs an interpolated pulse signal CP so that the tool is moved along a designated shape prestored in a graphic data memory device. An axis control circuit generates speed commands for respective axes in response to the interpolated pulse signal CP and sends the generated commands to a servo amplifier. The servo amplifier delivers a drive current I to energize servomotors mounted on a machine tool. A load determination device detects the drive current I from the servo amplifier and determines whether the detected current I decreases at a given ratio. When the drive current I decreases, for example, by 5%, a drive stop signal S is supplied. The interpolating device stops outputting the interpolated pulse signal CP in response to the drive stop signal S, and the tool feed is stopped accordingly.

    • A numerical control apparatus for controlling a machine tool to simply and accurately cyclically machine a workpiece. When the operator enters graphic data such as circular or rectangular graphic data in an interactive fashion from a keyboard or the like according to guidance information displayed on a display unit, a graphic data memory device stores the entered graphic data. A converting device calculates a machining path for cyclically machining a workpiece based on the graphic data and converts the machining path into NC commands, which are then stored in an NC command memory device. An interpolating device outputs an interpolated pulse signal to move the machine tool along the cyclic machining path based on a pulse signal from a manual pulse generator or a jog feed button on a machine control console. By freely operating the machine control console, the operator can easily and accurately effect cyclic machining on a workpiece while confirming a machined status.
