为了提供一种对车间条件具有良好适应性的切削力信号获取方法，研制了一种基于特殊处理的标准刀柄和光纤传感器的切削力测量装置。刀柄的处理方式是，在切割过程中，其后部将出现与切削力F-z成正比的位移。然后，安装在刀架上的光纤传感器检测作为切削力测量的位移。使用该装置不需要额外的安装空间，并且不影响换刀操作的便利性。此外，由于测量是在刀柄的后部进行的，因此可以避免切屑和冷却液的干扰。对该装置进行了标定试验和实际切割试验。结果表明，该装置具有良好的静、动态性能，其输出信号的频谱特征对刀具状态敏感。
With a view to providing a way of obtaining cutting force signals which possess good adaptability to workshop conditions, a cutting force measuring device based on a specially treated standard tool shank and an optical fibre sensor is developed. The tool shank is treated in such a way that during a cutting process a displacement proportional to cutting force F-z will occur at its rear part. The displacement is then detected as a measure of the cutting force by the optical fibre sensor which is mounted on the tool post. With this device no undue extra space is required for the installation and the convenience of the tool changing operation is unaffected. Besides, as the measurement is done at the rear of the tool shank, disturbances from chip and coolant may be avoided. A calibration test and real cutting tests of the device are carried out. The results show that the device possesses satisfactory static and dynamic performances and the spectrum feature of its output signal is sensitive to tool condition.
