35 wire EDM Fundamentals Revolutionizing MachiningWire Electrical Discharge Machining (EDM) is one of the greatest innovations affecting the tooling and machining industry. This process has brought dramatic improvements to industry in accuracy, quality, productivity, and earnings.

Now, with the aid of a computer and wire EDM machines, extremely complicated shapes can be cut automatically, precisely, and economically, even in materials as hard as carbide. See Figure 2 EDM BeginningsIn 1969, the Swiss firm Agie produced the world's first wire EDM machine. Typically, these first machines in the early '70s were extremely slow, cutting about 2 square inches an hour (21 mm2/min.)
