Abstract
A method and device for monitoring the condition of an electrode in an electro-discharge machine are disclosed. The device includes an electrode detector operable to produce a position signal indicative of the position of an end region of the electrode in the nose-guide, and a signal processing unit connected to receive a position signal from the electrode detector and operable to determine from the position signal when retraction of the electrode into the nose-guide has occurred. The method monitors the position of the end region of the electrode and determines when retraction of the electrode has occurred.
