Abstract
The invention relates to electrochemical machining of metal pieces, and, in particular, rings of bearings, in a controlled way. To achieve this process, parameters, such as current, are actively controlled. This allows the raceway to be completed sooner and with a smoother, more circular surface. In addition the active control makes the formation of more complex forms possible and is suitable for the cheap manufacture of trilobed raceways.
