Latest Patents

One of her latest patents is for an ECM trepan of bars. This apparatus features a stationary cathode tool with a passage and a drive mechanism that moves a bar-shaped workpiece through the passage while simultaneously rotating it. Electrolyte flows from a manifold at one end of the cathodic tool to another, establishing an electric current in the electrolyte. The internal shape of the cathodic tool wall transitions from a circular entry opening to a lobed exit opening, creating helical lobes in the workpiece. Another significant patent involves a progressive cavity pump/motor stator, which utilizes electrochemical machining to generate helical lobe profiles. This process includes bonding a thin, elastomeric liner to the stator or rotor, enhancing the bonding through electrical etching during machining.
