The present study proposed a novel strategy for removing the adhesion layer from the tool surface and recovering the cutting tool performance without detaching the cutting tool from the machine tool; namely, an on-machine tool resharpening process. To achieve efficient removal of the aluminum adhesion layer from the tool surface, the phenomenon of liquid metal embrittlement (LME), which is defined as a brittle fracture, or loss in ductility, of a ductile material in the presence of a liquid metal was employed. A series of milling experiments clearly showed that the developed strategy employing liquid gallium successfully removes the aluminum adhesion from the tool surface without damage to the tool substrate, and the resharpened tool shows excellent cutting performance nearly equivalent to its virgin state.

本研究提出了一种新的策略，用于从工具表面去除粘附层并恢复切割工具性能，而无需从机床上脱离切割工具。也就是说，这是一个机上的工具重新安装过程。为了有效地从工具表面从工具表面取出铝粘附层，采用了液态金属含量（LME）的现象，该现象被定义为在存在液体金属的情况下定义为易延展材料的脆性断裂或延展性损失。一系列的铣削实验清楚地表明，采用液体着甘油的开发策略成功地去除了工具表面的铝粘附力而不会损坏工具基板，而重新培养的工具显示出极好的切割性能，几乎等同于其处女状态。
