Abstract The friction at chip-tool interface can considerably affect the chip formation and consumed energy during cutting of superalloys. However, it is difficult to deliver the lubricant to the chip-tool interface to reduce the friction effect. Thus, this paper proposed a novel solution of insert design by locating macro-channels on the rake face which connect with the micro-channels for irrigating the coolant into the chip-tool interface, while considering the cooling and lubricating efficiency. A significant reduction of tool wear, cutting force and specific cutting energy has been demonstrated, while an improved chip fragmentation as well as microstructure has also been achieved.

在切屑刀具接口处具有多通道冲洗的新型切削刀片：建模、设计和实验

摘要 切屑-刀具界面的摩擦对高温合金切削过程中切屑的形成和消耗的能量有很大影响。然而，很难将润滑剂输送到切屑-刀具界面以减少摩擦效应。因此，本文提出了一种新的刀片设计解决方案，通过在前刀面上定位宏通道，与微通道连接，将冷却液注入切屑刀具界面，同时考虑冷却和润滑效率。已经证明刀具磨损、切削力和比切削能量显着降低，同时还实现了切屑碎片和微观结构的改善。
