提出了一种高精度、固有频率好、交叉干扰可接受的高速车削加工用高性能三轴切削力传感器。从环理论中汲取灵感，选用八角形环作为传感器的敏感元件。为了获得三轴切削力分量和抑制交叉干扰，提出了一种新型的两个相互垂直的八角形环结构，并专门组织了三个惠斯通全桥电路。首先，对新研制的传感器进行了静态标定测试；测试结果表明，该传感器在0.38% ~ 0.83%的范围内具有良好的测量精度。其次，进行了冲击模态试验，确定了传感器在三轴方向（1147 Hz、1122 Hz和2035 Hz）的固有频率，表明所设计的传感器可用于高速车床主轴转速不超过17205转/分钟的连续切削工况下的切削力测量。最后，通过在车削过程中的应用，验证了该传感器在实时测量切削力方面的性能；实测的切削力与切削参数的变化具有较好的一致性。因此，所研制的传感器具有良好的性能，在车削过程中实时测量切削力方面具有很大的潜力。
This paper presents a high performance triaxial cutting force sensor with excellent accuracy, favorable natural frequency and acceptable cross-interference for high speed turning process. Octagonal ring is selected as sensitive element of the designed sensor, which is drawn inspiration from ring theory. A novel structure of two mutual-perpendicular octagonal rings is proposed and three Wheatstone full bridge circuits are specially organized in order to obtain triaxial cutting force components and restrain cross-interference. Firstly, the newly developed sensor is tested in static calibration; test results indicate that the sensor possesses outstanding accuracy in the range of 0.38%–0.83%. Secondly, impacting modal tests are conducted to identify the natural frequencies of the sensor in triaxial directions (i.e., 1147 Hz, 1122 Hz and 2035 Hz), which implies that the devised sensor can be used for cutting force measurement in a high speed lathe when the spindle speed does not exceed 17,205 rev/min in continuous cutting condition. Finally, an application of the sensor in turning process is operated to show its performance for real-time cutting force measurement; the measured cutting forces demonstrate a good accordance with the variation of cutting parameters. Thus, the developed sensor possesses perfect properties and it gains great potential for real-time cutting force measurement in turning.
