Abstract
A method and apparatus for controlling a cutting machine for automatically cutting material according to a standard pattern with an assigned name which has been placed on the material and machine-readable coding placed on the pattern that is represents of the name. Contour data are stored in a CNC-control pattern memory, which enable the cutting machine to cut along a contour defined by the pattern, when the pattern name is received. Coding is automatically detected on the pattern, and if present, the coding is read to determine the pattern name and its position on the cutting machine. The pattern name, and lateral and angular displacement data indicating of the position of the pattern are automatically supplied to control the cutting machine. The apparatus comprises detecting and reading systems including an optical detector on the cutting machine producing a video output signal; a digital image memory; and an image decoding system. The digital image memory includes an input circuit for receiving the video output signal, comparing the video output signal against an adjustable threshold to produce binary video data, and generating a sync signal.
