Optimization design for eddy current sensor of water cutting robot

To realize intelligence of precise processing for random space orbit and in view of metal plate, a waterproofing and non-contact eddy current sensor is designed and applied into water jet cutting robot system in this paper. This paper studies mathematical model of eddy current sensor and analyzes influence of coil parameters on sensor performance. The section shape of coil is designed to be an inverse trapezoid. Based on these, an effective optimization design method is proposed in this paper. This method enlarges linear measurement range of sensor. The actual production process verifies that the system has small cutting error, fast response, high location precision and high production efficiency, and the system operation is stable and reliable.
