Abstract: Modern manufacturers use CAD, CAM, CNC automation, quality systems and PLM platforms that often operate as isolated data silos, causing duplicated effort, delayed change propagation and weak traceability. This paper presents an integrated smart-manufacturing framework that links CAD, CAM, automation and data acquisition, inspection and Product Lifecycle Management (PLM) through a continuous digital thread. The framework is demonstrated in two case studies: (i) CNC machining of a bearing housing, covering CAD release, CAM tool-path simulation, sensor-based data logging and inspection linked to drawing revisions; and (ii) a Cortona3D workstation-planning study, in which a Siemens Teamcenter bill of materials drives interactive 3D work instructions for a motorcycle assembly and maintenance process. Compared with manual work planning, the integrated approach reduced work-instruction authoring time by about 75–80% (40–60 h to 8–12 h), first-time-through assembly defects from 8.5% to 1.8%, and operator training from 5 to 1.5 days, while enabling real-time propagation of engineering changes. The results indicate that connecting design, manufacturing and lifecycle data improves productivity, quality and traceability, and offers a scalable route to Industry 4.0 adoption for small and medium-sized enterprises (SMEs).
