Abstract:By combing the laser technology with modern control theory and microcomputer technology, and by means of the z-axial follow-up system using a MCS-51 type single-chip microcomputer as backbone controller and the corresponding data-processing control software, a kind of adaptive control system suitable for laser cutting was designed. This control system lays a theoretic foundation for the wide use of laser processing.
