How to control the movement of the laser head accurately is the core problem of laser marking system. Interpolation and calibration algorithm, which directly affect the quality and results of marking, are the most important part of laser marking system. A marking motion control system is introduced, which makes use of DSP-BF533 as a hardware platform and adopts the optimization of linear interpolation algorithm and the calibration algorithm. The system successfully obtains a satisfactory output of vector graphics based on the marking precision, therefore, enhances the processing precision of marking.
