Cutting force is a significant indicator for in-process monitoring of cutting status. Although dynamometers are widely used in cutting force measurement, they are not suitable for nano-cutting due to insufficient sensitivities and low integrating possibilities. This paper presents a smart tool holder composed by piezoelectric ceramics and a flexible hinge, which could be integrated with a fast tool servo (FTS), for three-axial cutting force measurements in micro/nano-cutting. An algorithm was developed for enabling its quasi-static force measurement. Experiments were performed to verify the capabilities of cutting force measurement, demonstrating a high measurement sensitivity for indicating the micro/nano-cutting status.

切削力是切削状态在线监测的重要指标。虽然测功机广泛用于切削力测量，但由于灵敏度不足和集成可能性低，它们不适合纳米切削。本文提出了一种由压电陶瓷和柔性铰链组成的智能刀架，可与快速刀具伺服 (FTS) 集成，用于微/纳米切削中的三轴切削力测量。开发了一种算法以实现准静态力测量。进行了实验以验证切削力测量的能力，展示了指示微/纳米切削状态的高测量灵敏度。
