Abstract

Procédé d'usinage par électro-érosion, par pénétration progressive d'une électrode de forme prédéterminée dans une pièce à usiner, pour y pratiquer une empreinte également de forme prédéterminée. L'électrode 3 est déformée par rapport à la forme de l'empreinte 1 que l'on désire Cette déformation est un rétrécissement croissant à partir du point situé au fond de l'empreinte, pour tenir compte de l'élargissement 1a que donnerait une électrode 3a conforme à l'empreinte 1. Application à toute opération d'usinage par électro-érosion.Method of machining by electro-erosion, by progressive penetration of an electrode of predetermined shape into a workpiece, in order to make an impression there also of predetermined shape. The electrode 3 is deformed with respect to the shape of the impression 1 that is desired This deformation is an increasing narrowing from the point located at the bottom of the impression, to take into account the enlargement 1a that a electrode 3a conforms to the impression 1. Application to any machining operation by electro-erosion.
