本文提出了一种新型的智能车削刀具使用嵌入式压电传感器的实时测量切削力精密车削操作。创新是建立在刀柄中的压电传感器阵列，以获得智能车削刀具，这是强大的，工业上可行的和可改装的，并集成了足够的测量精度和过程中的传感能力。在设计中，四片压电传感器作为一个阵列集成到特殊设计的刀柄，直接产生电荷的切削力。利用测量解耦算法，对四个电荷输出信号进行放大、采集和解耦处理，推导出切削力。使用精心设计的切削试验进行刀具校准和性能测试，以工业可行的方式进一步评估和验证刀具设计。
This article presents a novel smart turning tool using the embedded piezoelectric sensors for real-time measurement of cutting forces in precision turning operations. The innovation is built with piezoelectric sensor array in the tool shank so as to obtain a smart turning tool, which is robust, industrial feasible and refittable and integrated with adequate measurement accuracy and in-process sensing capability. In the design, four pieces of piezoelectric sensors as an array are integrated into the specially designed tool shank, which directly generate charges under cutting forces. The four charge output signals can be amplified, acquired and processed through decoupling to deduce out the cutting forces with measurement decoupling algorithms. The tool calibration and performance testing are carried out using well-designed cutting trials to further evaluate and validate the tool design in an industrial feasible manner.
