Definitely powder mixing is one of the significant factor, however Pulse current and Pulse duration are the factor that influence the responses most.

Thanks!

But i want to know which factors of dielectric was improved on adding additive in EDM oil.

Is there is any change in viscosity or dielectric strength or any other factor that changed which improve maintainability.

It was established that when the plasma channel formed the conductivity increase with powders.

Powder as an additive is a means often used to increase the removal of material, but also to increase the surface quality or working accuracy. In my view is difficult to describe by a factor for a physical characteristic. For example, a splitting of the discharge can occur with certain powder grains, which are used per discharge base point smaller pulse energies. This lead to a significant improvement of the surface quality and machining accuracy. This same action can also lead to process stability when the mean gap width is in the order of magnitude of the powder grains. The addition of solid additives also has the disadvantage that the additives must be filtered out prior to the dielectrikum-regeneration, the additive must be re-introduced back to the processing. This results in the effect that the additives (solid) are only used when no other solutions are feasible, desired, or the surface quality may be produced by any other method.

For the simulation, it would be useful to the channel splitting is performed by a different distribution channel discharges with different initial diameters and different energy inputs.

Thanks for the reply

It is helpful for me to simulate the spark generated in the gap.
