摘要
基于ANSYS有限元分析软件建立Al2O3陶瓷激光铣削模型,利用APDL语言对激光铣削过程中的温度场动态分布进行模拟,分析激光功率和扫描速度对铣削宽度和铣削深度的影响,并进行激光铣削试验。结果表明:数值模拟所得的铣削宽度和深度与试验结果一致性较好,所建立的有限元模型可以较为准确地预测Al2O3陶瓷激光铣削效果。激光铣削宽度和深度随激光功率的增大而增大,随扫描速度的增大而减小,且较扫描速度而言,激光功率对铣削效果的影响更为显著。
A model of laser milling on Al2O3 eramic was established based on ANSYS finite element software.Laser milling process was analyzed by APDL code,and the dynamic distribution of the temperature field during the milling process was studied.The influence of the laser power and scanning velocity on the milling width and depth were investigated.According to the numerical simulation,the relevant parameters were used in the laser milling experiment.It indicated that the numerical simulation results were consistent with the experiment,the effect of laser milling on Al2O3 ceramic could be accurately predicted by the established model.The width and depth of laser milling were increased by laser power and decreased by the scanning velocity.Compared with the scanning velocity,laser power had more important influence on laser milling.
