渦電流式変位センサを用いたボーリング加工面の機上計測に関する研究

抄録

Eddy current sensors are generally used for measurement of flat surfaces. However, they have not been applied to cylindrical inner diameter surfaces such as after boring, and it is not known how concave surfaces affect the measurement. In this study, the effects of the material and inner diameter of the workpiece on the measurement accuracy in inner diameter turning were investigated from the perspective of experiments in which an eddy current sensor was actually mounted on a machine for measurement and FEM analysis. As a result, it was found that changes in the curvature of the inner surface affected the dimensional measurement.
