To achieve intelligential precision machining of arbitrary space orbit

a eddy current sensor with waterproof type and no contact is designed in view of sheet metal

and eddy current sensor is applied to water jet cutting robot system.Eddy current sensor research from the mathematical model

performance of the sensor coil parameters is analyzed

the shape of coil section is inverse trapezoid and the design of an effective optimization method is advanced

the linear measurement range of sensor is improved.Experimental results show that the cutting error of this system is small

the speed of response is quick

the pointing precision and the production efficiency are high

and system work is stable.
