Abstract
Segmented object manufacturing (SOM) is a hybrid foam 3D printer for plastic foams especially Expandable Polystyrene (EPS), which uses a novel visible slicing route. SOM has three subsystems include machining, slicing, and gluing systems; among these, the machining system contributes more in process time and surface quality. SOM is not yet commercialized because of poor product surface quality and high process time. In this work, efforts are made to reduce the cycle time and to improve the surface quality by optimizing the machining system. Taguchi method is used to design the experiments and parametric analysis of cutting speed, linear feed, step-over, and step-down is performed to get a good surface finish. As a result, surface roughness reduced from 78.30 to 47.70 µm, at the same time tool path also modified to accommodate the optimized parameters by doing so, process time reduced from 42 to 18 min due to optimized tool path.
