Description
Summary:Combining Additive Manufacturing (AM) and traditional machining processes is essential to meet components functional requirements. However significant differences arise in machining AM and wrought parts. Previous works highlighted the increasing of tool wear and worse surface finish. In this paper cutting forces are investigated as an indicator of material machinability. Milling cutting force coefficients are identified using mechanistic approach, comparing AISI-H13 wrought and AM specimen. Cutting force behaviour was investigated for two AM technologies: laser deposition (LENS) and wire-arc additive manufacturing (WAAM). Results show a general increase of cutting forces and coefficients of both AM materials, suggesting AM parts reduced machinability. Therefore, different cutting parameters should be selected for the AM material to achieve a sustainable production.
