Abstract


Additive Manufacturing (AM), particularly the Fused Deposition Modelling (FDM) technique, is gaining traction in industrial applications due to its versatility and cost-effectiveness. However, components produced by FDM often presents poor dimensional accuracy, geometric deviations, and inferior surface quality. This study investigates the effects of lathe turning post-processing on enhancing these properties. Using a Taguchi design of experiments, critical manufacturing parameters affecting dimensional accuracy and surface roughness were analysed. Results lead to significant improvements in dimensional precision and surface quality post-turning. Optimal finishing conditions identified include a spindle speed of 1200 RPM, cutting depth of 0.3 mm, and feed rate of 0.1 mm/rev, offering valuable insights into the hybrid AM-finishing approach.
