Sustainable Cutting Fluid Usage in Bandsawing of Additively Manufactured 316L Stainless Steel: Surface Integrity Evaluation
摘要
Metal additive manufacturing (MAM) components often require postprocessing for end applications. Bandsawing is an alternative process established in industry to remove parts from the build plate in wire arc additive manufacturing (WAAM). The removal of WAAM components from the build plate by bandsawing shows high potential, especially in the sustainable manufacturing of large-scale MAM parts. This work aims to study the influence of cooling conditions on the surface integrity of band sawed WAAM and conventionally manufactured 316L stainless steel. Sustainable cutting fluid strategies could impact surface integrity and their effectiveness in bandsawing MAM parts. The investigated cooling strategies are compressed air, minimum quantity cooling (MQC), and flood cooling. The surface integrity metrics of the band-sawed surfaces have been evaluated. The work aims to gain a deeper understanding of bandsawing AM components for industrial applications. Overall, the sustainable cutting fluid solution, MQC, has a similar effect on the surface roughness, microstructure, and cutting forces, compared to flood cooling.
