This Wire Electrical Discharge Machining Animated GIF (and Video) is Mesmerizing!
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.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
