Characteristics of the surface layer (SL) depend on different factors including phenomena that occur during its creation. They vary depending on the manufacturing technology that is used. Appropriately selected machining parameters make it possible to provide a surface with the required characteristics. This study presents a methodology, results and analysis of experimental tests carried out by electromachining and milling to determine the impact of the applied parameters on selected characteristics of the surface geometric structure (SGS). A comparison of those characteristics was performed for items made with the use of these technologies. Machining guidelines for devices operating under variable heat loading have been proposed.
