摘要：
Heat is easy to aggregate during drilling carbon fiber epoxy (C/E) composites because of the materials' anisotropy and the low thermal conductivity. It can result in a high temperature gradient which has a significant effect on the quality of the workpiece and the tool wear. In this paper, a drilling temperature field model of the unidirectional composites is developed. Based on the finite difference method (FDM) the temperature distribution and changes are simulated. Experiments of measuring the drilling temperature at the exit of the hole are carried out, and the results show that the temperature distribution is in agreement with the temperature field model.
