Recently I got a question on micro EDM of CFRP where micro channels were fabricated using copper tool. The question was as follows:

"The process parameters have been optimized in this study. But what about the experimental validation? Can it be possible to run the experiment at the obtained optimal conditions? If yes, then it should have been validated with experimental findings. Otherwise, what is the use of this optimal condition?"

The optimal values of feed rate and tool speed are 5.89 micron/s and 577.08 rpm respectively. I am unsure if those values can be set as input in a micro-EDM (Hyper 15) machine. And if not, then what will be the appropriate way to respond to the question as mentioned above?
