An on-line monitoring system for controlling the thickness and the flatness of NdFeB (Neodymium Ferrite Boron) laminate components during the skiving process is reported. The on-line monitoring system mainly consists of a non-contact eddy-sensor, a preamplifier, an A/D conversion card and a computer. The detailed description of the system with respect to the connection between the probe and the grinder is provided. Practical on-line measurement and data acquisition experiments are carried out. Experimental results indicate that the system principle is feasible and the accuracy is up to μm order. The monitoring system can be used to improve conventional grinders that are widely employed currently in China.
