A single machining program including turning and milling program steps together with a turning mode command or a milling mode command is stored in a program memory. When the turning mode command is read out from the program, a numerical control apparatus analyzes the program according to a G code architecture for lathe by numerical controller &num;1 for turning to control servo motors and a spindle motor. When the milling mode command is read out from the program, the apparatus analyzes the program according to the G code architecture for milling by a numerical controller &num;2 for milling to control the servo motors and the spindle motor.

Numerical control apparatus

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.
