ABSTRACT:
A programmed electrode wear compensation device and method for 3D EDM scanning apparatus has a compensation device which receives raw data about a working path of a working apparatus from a CAD/CAM device, calculates therefrom compensated data which take into account electrode wear and transmits the compensated data to a control device which controls the working apparatus, so that smoothness and shape of a machined surface are maintained during electric discharge.
