ABSTRACT:
An electric control system for a numerically-controlled form-cutting machine is disclosed. The form-cutting machine has two drive motors for moving a cutting tool respectively in an X direction and a Y direction. The control system comprises X-channel and Y-channel program-encoding means for encoding a program for numerically controlling the motion of the cutting tool in the X and Y directions respectively. The control system further comprises a magnetic-tape unit, for example, a cassette recorder, which can record the encoded programs on two tracks of magnetic tape. The control system further comprises X-channel and Y-channel program-decoding means for converting the signals played back from the magnetic-tape unit into signals suitable for controlling the motion of the cutting tool. The control system also includes conductive means interconnecting the components of the system.
