he development of laser technology and laser type were introduced.Each module’s function of the control circuit and the mechanical transmission mechanism of the laser engraving machine based on Arduino platform were described.The GRBL Controller control software operating process was described briefly.The mechanism of blue violet laser vaporization carved wood and bamboo and combustion process was analyzed.And the best process scheme was gotten.Practice has proved that the engraving machine based on Arduino platform is small in size,easy to carry,covers a small area,has compact structure.It has a good application value in the field of intelligent manufacturing in the future.
