The loads acting on a workpiece during machining processes determine the modification of the surface of the final workpiece and, thus, its functional properties. In this work, a method that uses thermocouples to measure the temperature in precision fly-cutting machining with high spatial and temporal resolution is presented. Experiments were conducted for various materials and machining parameters. We compare experimental measurement data with results from modern and advanced machining process simulation and find a good match between experimental and simulation results. Therefore, the simulation is validated by experimental data and can be used to calculate realistic internal loads of machining processes.
加工过程中作用在工件上的载荷决定了最终工件表面的改性，进而决定了其功能特性。在这项工作中，提出了一种利用热电偶在精密飞刀切削加工中以高空间和时间分辨率测量温度的方法。针对各种材料和加工参数进行了实验。我们将实验测量数据与现代先进加工过程模拟的结果进行比较，发现实验结果与模拟结果吻合良好。因此，该模拟通过实验数据得到了验证，可用于计算加工过程中实际的内部载荷。
