A method for forming a piece of a sheet metal is performed by positioning a consumable body, made of metal, proximate to the piece of the sheet metal. The consumable body is rapidly vaporized, and the gas pressure generated thereby is directed into the piece of the sheet metal.

Depending upon the type of stationary body, the piece of sheet metal is deformed into a predetermined shape or is welded onto the stationary body. The vaporization is accomplished by passing a high current of electricity into the consumable body. The effect of the vaporized metal may be augmented by additional components in the consumable body.

When violinist Anne Akiko Meyers embarked on a new interpretation of Philip Glass' "Metamorphosis ," the composer directed her to his longtime collaborator Michael Reisman. Turns out Reisman was already collaborating with Meyers in her new release in an arrangement of Arvo Pärt's "Fratres." These two meditative pieces on Meyers' album Mirror in Mirror (itself a reference to Pärt) contribute to a whole characterized by haunting beauty—featuring lullabies and sunken ships. "You have to create this beautiful sonic world full of color and movement and breath, and to make it sing, yet while sculpting these long, slow notes," says Meyers of Reisman's adaptation. "It felt to me like color coating a glacier." Listen to the full conversation between Of Note's Katy Henriksen and violinist Anne Akiko Meyers by clicking on the streaming link above.

If you're designing metal parts, you'll need to do things differently than you would for other materials and processes. This course shows how to use Autodesk Fusion 360—the affordable cloud-powered CAD and CAM tool that works like more expensive, industry-focused tools—to build effective designs specifically for subtractive manufacturing in metal. Thom Tremblay shows how to build solid designs, simulate how the model will hold up to the stress of production and use, render the design for presentation, and finalize it for manufacturing. The workflows showcased in this course are tailored to help the nonprofessional CAD user, and the maker, to be more effective and quickly have access to the tools that a few years ago were only available to the few and at an astronomical price.
