Abstract
A process for producing a pattern in the surface coating of an electrode used in an electrochemical machining process comprises the steps of providing a cylinder having a body composed of an electrically conductive material and a surface coating of an electrically insulating material and exposing the surface coating of the cylinder to a source of light in accordance with the pattern. Locators(s) may optionally be formed on the surface of the cylinder to assist in positioning the electrode in a predrilled hole.
Claims19
A process for patterning a shaped-tube electrochemical machining (STEM) tool comprising;
- providing an electrically conductive STEM cylinder coated by an electrically insulating coating;
- and
- exposing the insulating coating to a source of collimated light in accordance with a pattern defining raised areas to be formed on an internal surface of a predrilled hole in a workpiece.
A process for patterning a shaped-tube electrochemical machining (STEM) tool comprising;
- providing an electrically conductive STEM cylinder coated by an electrically insulating coating;
- and
- laser ablating the insulating coating in accordance with a pattern defining raised areas to be formed on an internal surface of a predrilled hole in a workpiece.
