An electrical discharge machine. Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). [1]
A continuous electric spark discharge may be drawn between probe and tissue, especially at the highest settings of power, although this is not necessary for the device to function. The amount of output power is adjustable, and the device is equipped with different tips, electrodes and forceps , depending on the electrosurgical requirement.
A second category consists of machine-based works: he has devised a number of conceptually-challenging art-making machines, like the SCUMAK (Auto Sculpture Maker), 1998, PMU (Painting Manufacturing Unit), 1999–2000, [8] and the Erosion Machine, 2005. Bridging the gap between the naturalistic and mechanized works, Paine also creates large ...

Typical water jet cutting machines have a working envelope as small as a few square feet, or up to hundreds of square feet. Ultra-high-pressure water pumps are available from as low as 40,000 psi (280 MPa) up to 100,000 psi (690 MPa). [44] There has also been a growth in small, desktop-sized machines that operate at pressures under 10kpsi.
Spark plasma sintering, also known as plasma pressure compaction (P2C) sintering, equipment are commercially available now and are no longer limited to laboratory research work. Products like body armor, rocket nozzles, carbon fiber composites and several other hybrid materials can be produced in commercial scale using these equipment.
The Spark Arrester Guide is used by field inspectors and consumers to verify product certification status. Manufacturers pursuing spark arrester qualification in the United States should consult the USDA Forest Service's "Manufacturer's Submission Procedure" for both general purpose [6] and small engine [7] spark arresters.
The steel must be hardened but softer than the flint-like material striking off the spark. [12] Old files, leaf and coil springs, and rusty gardening tools are often repurposed as strikers. Besides flint, other hard, non-porous rocks that can take a sharp edge can be used, such as chert, quartz, agate, jasper or chalcedony. [2]
