Machining of an integrally bladed stainless steel wheel by high rate anodic dissolution is discussed. The use of sodium chloride leads to spark-free machining but suffers from the disadvantage of heavily reduced blade profile. Sodium nitrate, on the other hand, leads to a sharp profile but has a tendency to spark. A method of overcoming the problem of sparking is discussed. Design of tool in relation to the machining of integrally bladed wheel is described.
