Abstract
An electrical discharge machining assembly has a fixture that retains an electrode. The fixture has clamps to apply a clamping force to the electrode. A threaded member adjusts the compression of a spring to change the clamping force for each clamp. For each clamp, the spring applies a force to a clamp lever pivotably attached to the fixture. Pivoting of the clamp lever moves a lower portion of each clamp lever closer to the fixture clamping the electrode to the fixture body. A clamp release is located proximate to the fixture to rotate the clamp levers in an opposite direction releasing the clamping pressure and the electrode.
