With accuracy of +/-0.0001″ the cut piece virtually disappears into the main block body. Watch the video below to see further explanation and demos including lining up (or not) grain in material and how quickly air reacts with the shape falling into place – amazing!
Out of his wealth of tool and die making experiences, Carl Sommer, an award-winning teacher, shares about EDM machining accuracy and heat expansion. Wire EDM can cut with accuracies of +/-.0001″. Sommer demonstrates what .0001″ is and how heat affects tolerances, and then how accurate wire EDM can machine parts.
Sommer, president of Reliable EDM, started in the machining trade in Brooklyn, N.Y. He has worked as a tool and diemaker, machinist, foreman, tool designer, and operations manager for a large tool, die, and stamping company.
