Mechanik nr 12/2019 - Obróbka - inne rodzaje

ABSTRACT: Perspectives of applications WEDM for cutting titanium alloys are presented. There is space to explore how application of proper time parameters and the material of wire electrode for WEDM of titanium alloys affects the surface roughness, structure, the stress and the chemical composition of the formed surface layer.

KEYWORDS: WEDM, titanium alloys, heat affected zone
