Abstract
A new eddy current sensor with planar coils designed for noncontact distance measurement was applied in the inter electrode gap detection in the electrochemical machining (ECM). The sensor consists of two micro electroforming planar coils (driver coil and sensitive coil) stacked on the magnetic core. The magnetic model of the detection principle was built, and a new micro motion system was developed as a test and machining platform also. The size of the sensor was: Φ5 mm × 1.5 mm. The results show that the sensor is compact enough to nondestructively assess the electrode gap distance and could be easily integrated into a tool cathode for real-time electrolytic machining gap detection.
设计用于非接触式距离测量的新型平面线圈涡流传感器被应用于电化学加工（ECM）中的电极间隙检测。传感器由叠加在磁芯上的两个微型电铸平面线圈（驱动线圈和敏感线圈）组成。我们建立了检测原理的磁性模型，并开发了一个新的微型运动系统作为测试和加工平台。传感器的尺寸为Φ5 mm × 1.5 mm。结果表明，该传感器结构紧凑，可无损评估电极间隙距离，并可轻松集成到工具阴极中，用于实时电解加工间隙检测。
期刊介绍：
The aim of the Journal of Mechanical Science and Technology is to provide an international forum for the publication and dissemination of original work that contributes to the understanding of the main and related disciplines of mechanical engineering, either empirical or theoretical. The Journal covers the whole spectrum of mechanical engineering, which includes, but is not limited to, Materials and Design Engineering, Production Engineering and Fusion Technology, Dynamics, Vibration and Control, Thermal Engineering and Fluids Engineering.
Manuscripts may fall into several categories including full articles, solicited reviews or commentary, and unsolicited reviews or commentary related to the core of mechanical engineering.
