Abstract
An apparatus is provided for electrical erosion by electrical discharges across the gap between an electrode and workpiece being eroded. A sensor means provides information regarding the electrical condition in the gap.
Claims13
Apparatus for working electrically conductive materials by electrical erosion, comprising an electrode adapted to be placed next to an electrically conductive workpiece to be machined, leaving a gap across which electrical discharges may occur, means for applying a voltage between the electrode and workpiece to cause electrical discharges to occur, and sensor means for detecting the positions at which electrical discharges are occurring along the gap to give an indication of the relative orientation of the electrode and workpiece with respect to each other.
Apparatus for working electrically conductive materials by electrical erosion, comprising an electrode adapted to be placed next to an electrically conductive workpiece to be machined, leaving a gap across which electrical discharges may occur, means for applying a voltage between the electrode and workpiece to cause electrical discharges to occur, means for giving an indication of the discharge voltage of the electrical discharges to provide control information for controlling the texturing conditions in the gap, and said giving means comprising a sample and hold circuit to sample the discharge voltage of the electrical discharges.
