红外热成像技术检测金属切削过程温度场分布

Determination the Distribution of Tool-chip Interface Temperature Using Infrared Thermography Technique

通过采用红外热成像技术检测了切削过程中刀/屑接触面温度分布,试验表明,刀/屑接触面上的最高温度随着切削速度和进给速度的提高而升高,刀具前角大小对切削温度影响较小。证实了红外热成像技术在检测金属切削过程中温度分布的可行性,为选择最佳切削工艺参数提供了可靠的依据。

The distribution of tool-chip interface temperature is determined by using infrared thermography method. The experiments resuhs showed that the maximum tool - chip interface temperature increases with increasing cutting speeds feed speeds, and the relationship between the maximum tool - chip interface temperature and the rake angle is not distinctive. The experiments also confirmed that infrared thermography method can be used to determine the distribution of tool-chip interface temperature accuracy.
