The current state of the art shows that the friction behavior during machining is not yet sufficiently understood and that there is still a need for further research. This represents a major obstacle to the successful further development of friction models for chip formation simulations. Therefore, a novel method for the analysis of friction mechanisms in machining via high-speed chip formation recordings is presented in this study. Within the frame of the investigations, a significant influence of the sliding velocity of the chip on the coefficient of friction could be determined over a wide range of different coating properties and cutting velocities.

通过数字粒子图像测速仪（DPIV）确定加工过程中摩擦行为的速度相关性的新方法

现有技术表明，尚未充分理解加工过程中的摩擦性能，并且仍需要进一步的研究。这是成功进一步开发用于切屑形成模拟的摩擦模型的主要障碍。因此，本研究提出了一种通过高速切屑形成记录分析加工中摩擦机理的新方法。在研究的框架内，可以在很宽的不同涂层性能和切削速度范围内确定切屑滑动速度对摩擦系数的重要影响。
