with rapid development of photoelectron technology, application area of laser marking machine becomes much wider and marking precision becomes much higher. development of laser industry is presented by 3 factors: firstly, laser technology which is used for processing related materials; secondly, mechanism and controlling system; thirdly, laser processing technique. as laser technology is mature for a long time, people s effective control of laser equipment and laser processing technique become the bottle neck in application of laser marking technology.
at present, there are many manufactures of laser marking machine in china. competition of laser equipment technology has been changed to effective control of laser equipment and processing technique. whether the following questions can be solved or not becomes the key in competition: 3d multi-axis linkage high speed laser scanning vibration of fast impetus scanning format scanning precision malposition of synchronized scanning and to-and-fro scanning complex arithmetic and interpolation of regular graphics.
