Measuring Airfoil Blades on a Coordinate Measuring Machine

Airfoil blades are precision components found in gas turbines and jet engines, where they convert thermal or kinetic energy into mechanical motion. Due to their aerodynamic and thermal demands, the geometry of an airfoil must be meticulously controlled. Inspection using Coordinate Measuring Machines (CMMs) enables high-accuracy assessment of geometric features such as camber, twist, thickness, and chord length. Combined with CAD-based evaluation and mathematical analysis, this method forms a comprehensive quality control process.
