Numerically controlled cutting control device and numerically controlled cutting control method

The invention relates to a digital control cutting control device, comprising a digital control cutting machine, which is used to drive moving mechanisms in X and Y axes of the digital control cutting machine; a laser marking machine, which is used to generate marking machine control files and cutting command files, and automatically marks and lines out according to the marking machine control files. The invention also relates to a digital control cutting control method, comprising a laser marking machine storing and operating marking machine controlling files. At the same time, the digital control cutting machine stores and operates the cutting command files. The digital control cutting machine drives the moving mechanisms in X and Y axes according to the cutting command files so as to drive a laser marking head to a target area, and sends out informing signals to the laser marking machine. The laser marking machine responds to the informing signals to automatically mark and line out from the garget area, implementing the marking machine control files. With advantages of reliable, visual and fast marking and accurate lining without damaging steel plates, the invention can automatically line out on parts.
