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.

A device for monitoring the condition of an electrode received in a nose-guide of an electro-discharge machine, the device comprising an electrode detector operable to produce a position signal indicative of the position of an end region of the electrode with respect to 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 or whether retraction of the electrode into the nose-guide has occurred by detecting retraction of the electrode to a predetermined retracted position within the nose-guide.
A method of monitoring the condition of an electrode in the nose-guide of an electro-discharge machine comprising monitoring the position of an end region of the electrode in the nose-guide and determining when retraction of the electrode from an operating position to a predetermined retracted position within the nose-guide has occurred.
