“…The knowledge of the state of the subsurface layer is a key aspect necessary to determine and assess the proper functionality of a manufactured component and its expected service life. In fact, if there are defects in the subsurface area in the form of cracks, such as X210Cr12 steel and their various heat treatments [11] or in the form of burnt cavities, such as Creusabro 4800 [29], Hardox 400, or Hadfield steel [21], it is very likely that the correct functionality or service life of a component will not be maintained. For this reason, it is always necessary to know whether it is necessary to optimize the machine setting parameters, the cutting direction of the semi-product or other aspects to eliminate these subsurface defects or not.…”

“…The analysis of the subsurface layer was performed on pre-prepared metallographic preparations of all samples using electron microscopy. This analysis is crucial because in many materials, extensive defects in the form of cracks or burnt cavities have been found in this way, e.g., in the Mouralova study [6,7,10], that significantly affect the correct and required functionality of the component and its service life during subsequent use. The cross-sections were observed on a Lyra3 device using a backscattered electron (BSE) detector, each with a magnification of 1000× and then 2500× and 4000×.…”

“…The machining length in the form of cutting speed can be reduced primarily by the suitable optimization of the machine parameters settings, while also taking into account the resulting quality of the machined surface and also the dimensional accuracy. To optimize the WEDM process for different materials, many extensivedesigns of experiments and studies have been performed, e.g., optimizing the machining of Creusabro [6], Hardox [7] or Hadfield steels [8] and aluminium alloys 7475-T7351 [9], or finding the occurrence of subsurface defects depending on their lifetime [10]. The aim of this study was to present the results of a detailed and extensive optimization process for machining the Nimonic C 263 super alloy using WEDM, and no such extensive experiment has been performed with this material in similar studies.…”

“…Die-sinking EDM is a technological process where it is necessary to ensure machining efficiency and maximize the material removal rate while maintaining excellent surface and subsurface quality. To investigate in detail all the input factors affecting the erosion process of various types of steel, extensive research has been conducted including the influence of the cutting orientation of the semi-product, depending on its heat treatment for X210Cr12 steel [21], Hadfield machinability analysis [22], Creusabro [23], and Hardox steel [24] by using the design of experimentsand analysis of durability due to the occurrence of surface and subsurface defects [25]. The purpose of this study was a complex analysis of EDM-machined surfaces of individual experimental samples concerning the state of the subsurface area and formed defects.…”
