Report

High-precision parametric Scan-to-CAD reconstruction of an automotive Inline-4 (I4) Cast Turbo Exhaust Manifold. This model was reverse-engineered from high-density 3D scan data in Geomagic Design X, accurately recovering design intent, restoring worn/cast nominal dimensions, and establishing precise geometric relationships for downstream engineering and performance fabrication. Engineering Highlights & Geometry Scope: • 4-into-2 Divided Runner Routing: Accurately captured smooth, aerodynamic internal exhaust gas paths pairing cylinders 1-4 and 2-3 for balanced twin-scroll turbocharger spooling. • Precision Machined Flanges: Reconstructed true planar cylinder head mounting faces (with standard 2-bolt port patterns) and the dual-port turbine inlet flange. • Auxiliary Flanges & Features: Modeled the integrated 2-bolt EGR (Exhaust Gas Recirculation) port, heat shield mounting bosses, and structural cast stiffening ribs. • Manufacturing & DFM Intent: Uniform wall thicknesses and smooth transition fillets developed to match industrial casting and CNC port-matching standards. Software & Deliverables: • Software Used: Geomagic Design X, SolidWorks • Available Formats: STEP (AP214 / AP242), Parasolid (.x_t), IGES, STL mesh, and native parametric feature trees.
