In this article the results concerned influence of processing conditions of the wire electrical discharge machining and vibro‐abrasive machining on the surface layer and morphology of samples made of hard machinable materials used in aircraft industry like: Titanium 5553 β, Inconel 617, Hastelloy X and Magnesium AZ31 have been presented. For this purpose the cubic and cylindrical samples made of hard machinable alloys have been prepared using optimal electric parameters of wire‐cut electrical discharge machining and finally they have been polished using circular vibratory finishing technology and different ceramic shaped stones.

In the article selected investigation results of surface morphology and geometrical structure after abrasive electro-discharge grinding (AEDG) and final polishing of samples made of hard machinable alloys used in aerospace industry has been presented. The machining parameters of samples have been determined and their surface geometrical structures after each stage of machining using 3D profiling have been estimated. Surface texture of samples has been assessed basing on microscope images.
