Airfoil blades, essential components of turbines and jet engines, require extreme precision in their geometry to ensure optimal aerodynamic performance, structural integrity, and energy efficiency. Accurate inspection of airfoils is paramount, and Coordinate Measuring Machines (CMMs) have become the gold standard for achieving this. This article outlines the critical steps, methods, and tools involved in inspecting airfoil blades on a CMM, including alignment, probing strategies, and feature evaluation.
