This article explores the practical implementation of Geometric Dimensioning and Tolerancing (GD&T) according to the ISO GPS standards, focusing on the functional definition and consistent application of Datum Reference Frames (DRFs). DRFs, derived from a component’s functional geometry and assembly sequence, constrain six degrees of freedom to ensure stable alignment and reproducibility during production and assembly.

The development of medical devices presents unique technical, regulatory, and economic challenges, requiring a multidisciplinary approach to ensure patient safety, reliability, and market competitiveness. Medical devices span a wide spectrum—from drug delivery systems to surgical robots—and must meet stringent functional, material, and regulatory requirements. A critical and often underestimated factor influencing their performance and manufacturability is mechanical variation, the inevitable deviation from nominal design that occurs during production.

Dimensional management in modern manufacturing demands more than just accurate geometric tolerances—it requires data consistency, traceability, and automation across the entire product lifecycle. Traditional practices like annotated PDFs and Excel-based inspection plans introduce risk and inefficiency by detaching product and manufacturing information (PMI) from the 3D model. Siemens’ NX Inspector addresses this challenge through the introduction of Model-Based Characteristics (MBC)—standards-compliant, machine-readable data objects that convert each PMI requirement into a uniquely identified, traceable element within the CAD environment.

A collaborative project between Nissan Technical Centre Europe, RBF Morph, and the University of Rome “Tor Vergata” showcases how multi-physics optimization is revolutionizing automotive wheel design, particularly for electric vehicles (EVs). By integrating styling, structural analysis, and aerodynamics within a unified workflow enabled by advanced mesh morphing technology (rbfCAE), designers can optimize wheels for lightweight, strength, and aerodynamic efficiency without compromising aesthetics.

Designing efficient, grease-lubricated gearboxes—particularly for high-load applications like steering drives—presents unique engineering challenges. SPN Schwaben Präzision, in collaboration with EnginSoft GmbH, uses advanced simulation tools to optimize gearbox lubrication, focusing on lifetime performance and minimal maintenance. Grease offers advantages such as long-term stability and effective adhesion but requires precise control of quantity and targeted distribution to prevent wear or overheating.

Fatigue design of large welded structures presents significant challenges due to complex geometries and variable loading conditions, especially in industries such as offshore engineering. While nominal stress-based methods remain widely used, they often fall short when applied to intricate welded details. This study investigates the use of MAGNA FEMFAT, a commercial fatigue analysis tool, to evaluate the fatigue strength of large welded K-nodes typically found in small offshore platforms.

ECM Technologies has significantly streamlined the design, installation, and commissioning of its large-scale heat treatment systems for the automotive industry by using digital twin technology and Rockwell Automation’s Emulate3D software. Faced with tight timelines and software compatibility challenges during a major project in Mexico, ECM used virtual models to simulate and test their systems in parallel with production. This approach reduced commissioning time by 50%.
