I believe that ECM was used to make the one piece main upper surface on
747 wings. I saw one in the Boeing Wichita plant back in about 1982 on a
tour. Don't know if its still used. I think also I have seen that Rolls
Royce have used it for forming turbine blades in the UK.

I'm a student of manufacturing engineering in the last term. My
graduating
project is about ECM. So, I'm gathering information about the
electrochemical machines.
I need to find some information such as proper ECM machine, power
supply,
process parameter control system, and electrolyte preparation, feed
and
purification system and the other practical and experimental
information.
Therefore, if possible please assist me in the mentioned subjects.


If you are aware of companies with ECM technology and / or aware of
application ECM is being applied please respond.
