Abstract
An electrochemical machining process is disclosed for forming multiple raised areas having multiple heights in a wall of predrilled holes within a workpiece. Positioned within each hole is an electrode coated with an insulating material in a pattern defining the raised areas to be formed in the wall of each respective hole. An electric current is applied from a power supply to each of the electrodes. A resistor is positioned between the power supply and at least one of the electrodes to vary the voltage passing through the electrode to vary the amount of material removed within that respective hole.

An electrochemical machining process for forming multiple raised areas having multiple heights in a wall of predrilled holes within a workpiece comprising:
- positioning in each hole an electrode coated with an insulating material in a pattern defining the raised areas to be formed in the wall of each respective hole, and
- applying an electric current from a power supply to each of said electrodes wherein a resistor is disposed between said power supply and at least one of said electrodes to vary the voltage passing through said at least one electrode and correspondingly vary the amount of material removed within that respective hole.
An electrochemical machining process for forming multiple raised areas having multiple heights in a wall of predrilled holes within a workpiece comprising:
- positioning in each hole an electrode coated with an insulating material in a pattern defining the raised areas to be formed in the wall of each respective hole, and
- applying an electric current from a power supply to each of said electrodes wherein a switch is disposed between said power supply and at least one of said electrodes to vary the time said electric current is applied to said respective hole and correspondingly vary the amount of material removed within that respective hole.
