I have another head scratcher apprenticeship question.
I am being asked to explain the application of dielectric fluids with regard to a range of different materials.
I understand the general purpose of the dielectric (for the spark to happen, to flush eroded material away and to cool), but I have no experience or knowledge of the various dielectrics with different materials. I only use DI water with carbide.
I'm not having much luck searching the internet either. The only thing I have found is that ferrous materials corrode during machining in DI water. I don't think this qualifies as "a range of different materials".
Please help, (again)
