Abstract: Metrology plays a critical role in ensuring dimensional accuracy, quality assurance, and process control in manufacturing environments. However, conventional metrology inspection tables are often expensive, bulky, and inaccessible to small-scale industries, educational workshops, and local fabrication units with limited financial resources. This research presents the design and fabrication of a low-cost metrology inspection table intended to meet essential inspection requirements while maintaining acceptable accuracy, rigidity, and usability. The proposed inspection table is developed using locally available materials such as mild steel structural sections and a precision-ground granite or steel top, combined with a simple leveling and vibration-damping mechanism. Design considerations focus on flatness, load-bearing capacity, thermal stability, and ergonomic accessibility to support common metrology instruments including height gauges, dial indicators, surface roughness testers, and coordinate measurement accessories. Fabrication processes involve conventional machining, welding, and surface finishing techniques that are readily available in small workshops, thereby reducing dependency on specialized manufacturing facilities. Performance evaluation is conducted through flatness measurement, deflection analysis under static loading, and repeatability assessment during dimensional inspection tasks. The results indicate that the developed inspection table achieves satisfactory flatness and structural stiffness for routine inspection operations, with performance comparable to entry-level commercial systems at a significantly reduced cost. The total fabrication cost is found to be substantially lower than imported metrology tables, making the solution economically viable for small-scale industries. The research demonstrates that careful design optimization and appropriate material selection can bridge the gap between affordability and functional accuracy. The developed low-cost metrology inspection table offers a practical solution for improving quality control practices in resource-constrained manufacturing environments, while also serving as an effective educational tool in technical training institutions and vocational laboratories.
