Abstract
Electrode tools for electroerosion (EDM) where a cavity or a relief is machined by hollowing out the part at great speed and in successive layers or slices by means of a rotating electrode tool of a simple shape which is independent of the cavity to be eroded, called “EDM slices milling”.
Claims5
A method for use of an electrode-tool on a machine for EDM slices milling, wherein said machine is programmed in such a manner that a tip of said electrode tool moves parallel to a plane of a slice of material of a workpiece to be eroded, comprising the steps of:
- simulating a variation of material removal and machining speed along programmed tool paths, by representing a non-cylindrically shaped tip of said electrode tool as having a cylindrical shape;
- and
- removing material by machining adjacent grooves in said slice of material of said workpiece, according to a sweeping motion.
