An on-line measurement system which is composed by standard sphere ,support rob and under-tested electrode was proposed. The usage of this measurement system is introduced along with its measure error analysis. The result of WEDG experiment shows that this measurement system can survey online-fabricated electrode accurately and effectively. It shows that the relative error between the on-line measurement system and the non contacting optical measurement system is less than 5 %. This measurement system provides a novel way for the survey of online fabricated electrodes in micro EDM.
