Wire electrical discharge machining (WEDM) is a key technological process for the production of parts from semi-finished products to the final heat treatment as it also enables the machining of very hard material. The quality of an electro-erosive machined surface is a very important factor with regard to the consequent functionality and life cycle of the manufactured part. The occurrence of cracks or burned cavities is therefore an acceptable defect of the sub-surface area, which along with residual stress may lead to the destruction of the machining. This study deals with the influence of the cut direction through a semi-finished product on the occurrence of defects (cracks, burned cavities) regarding the influence of setting up the parameters of the machine (gap voltage, pulse on and off time, wire feed and discharge current) and the type of heat treatment of the material. In order to study the surface and sub-surface area of the machined samples, electron microscopy was used, including the use of the local EDX chemical analysis.
