本文采用红外热成像技术检测了切削刀具温度分布,给出了多种工件材料、刀具材料及切削速度等条件下切削刀具的温度场;还研究了后刀面磨损量与刀具最高温度值及其分布特征之间的关系。试验表明:此技术可以快速、直观、非接触、较精确地在线实时无损监测切削温度,为选择最佳切削工艺参数、提高零件表面质量及刀具寿命提供依据。
In this paper, the temperature distribution of the cutting tool is detected by the infrared thermal imaging technology, and the temperature field of the cutting tool under a variety of workpiece materials, tool materials and cutting speed is given. The relationship between the flank wear and the maximum tool temperature The relationship between distribution features. The experimental results show that this technique can monitor the cutting temperature in real time and non-destructively on-line, in a fast, intuitive, non-contact and accurate way, and provide the basis for choosing the best cutting process parameters, improving the surface quality and tool life.
