Assessment of surface geometrical structure of hard to machine aerospace alloys after abrasive electro-discharge grinding (AEDG) and polishing

Abstract

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.
