Method and device for cutting sharp corners in an electrode workpiece by erosive discharge

摘要

The method consists in performing, over a path (25) before the apex (24) of a corner, a gradual slowing in the machining speed by progressively decreasing the frequency of the discharge between the electrode wire (1) and the electrode workpiece (4), and in continuing the machining at a reduced speed over a path (26) after machining of the apex (24).
