Abstract
The paper presents an innovative method for improving the shape precision of deep cylindrical holes, made by using WEDM (wire electrical discharge machining) technology.
Following the presentation of some general aspects, the mathematical model of the deformation of the middle fibre of the wire electrodes employed in the WEDM manufacturing process is presented in detail. This deformation generates significant distortions in shape, especially when the depth of the holes executed is significant. These distortions can be balanced out by sloping the wire electrode at a convenient angle during the manufacturing process. The principle of improving the shape precision, together with some experimental results, are presented next.
