This study presents the design and finite element analysis (FEA) of a gantry-type inspection machine frame actuated by three linear motor axes-two along the Y-axis direction and one wall-mounted X-axis supported through precision brackets. The frame is intended for top-surface inspection applications that demand high structural rigidity and vibration stability. The mechanical design was evaluated using ANSYS Workbench 18.0 through both static structural and modal analyses. The simulation results show a maximum deformation of 4.47 μm, a peak von Mises stress of 3.35 N/mm², and a first natural frequency of 49.90 Hz under combined static and dynamic loading. The outcomes confirm that the developed structure exhibits sufficient stiffness, strength, and dynamic robustness, making it suitable for integration into high-precision inspection systems.
