    • Abstract
  • In order to the accurate single-layer depth to meet the technologic requirement of 3-D laser carving,experimental study of laser carving was carried out on the surface of Al2O3 ceramic with different laser processing parameters.The effects of parameters on single-layer depth,quality and the mechanisms of laser carving were described.The mathematical model of laser carving depth was established.Through experiments,it was found that the single-layer depth was nearly 0.1mm with a tolerance of less than three-thousandths when the laser power was 12.2A,the scanning speed was 25mm per second and the repeating frequency of laser pulse was 2kHz.At last,a 3-D solid was successfully carved on the surface of ceramic sample based on the experimental results.It was shown from the results that the layered-forming principle could be applied in the field of laser carving and the 3-D laser carving system could directly carve the real 3-D graphics on the surface of ceramic.
