Wire Edm Cutting Speed Table

Whereas the diameter of a cutting tool determines the offset in milling the edm controller applies a cutter comp based on the diameter of the wire.

Wire edm cutting speed table.

Most machines can cut tapers of 20 30 degrees depending on workpiece thickness. Repeatability and longer tooling life are must haves with component miniaturization and increasing production volumes. He machine is built on the proven makino uj series wire edm platform that utilizes a stationary table design and is held to an even higher construction accuracy specification. Table travels wire edm s have u v travels for providing the movement to cut tapers.

Today some edm manufacturers boast advertised first pass cutting speeds using large diameter coated wires in excess of forty inch hour which is a far cry from the twelve inch hour of the 1980s or the twenty inch hour of the early 1990s. That s why fanuc has developed a next generation robocut wire cutting machine. The α cib series comprises three versatile all rounders including the first model with an 800 mm table. Moreover this increased power capacity allows the wire to cut efficiently at lower wire speeds relative to the feed rate.

Where wire edm is concerned accuracy has traditionally come at the cost of speed. Wire can take as much as 60 amps without breaking. The shape being cut is a cat figure again found from open clip art converted to dxf with inkscape and. The system consists of a.

Cutting parameters cutting speed feed normal cutting parameter recommendations for bds bd and fb inserts for typical mold steels 1 2311 1 2344 1 2711 1 2714 etc table 1 cutting conditions for using steel shank holders.

A typical 0 010 brass wire will break at higher power levels which is why standard wire edm generators typically top out around 30 amps. The wire edm in figure 1 represents current technology. For example if a 0 010 inch diameter brass wire is used the cutter comp will approach 0 005 inches plus a spark gap as the wire gets closer and closer to the part surface and possibly finish at.
