The WIZblade 3-D laser inspection system from Nextec Laser Metrology aids in high-speed measurement of aerospace jet engine blades as well as industrial turbine and compressor blades. The system overcomes the challenges of free-form blade measurement and inspection, significantly reducing inspection time while enhancing accuracy and sampling rates. It has allowed customers to decrease the turbine blade inspection process from 8 h to 55 min a day. The large dynamic range and high accuracy of the probe simplify setup of the alignment loop and airfoil cross-section path and allow collection of hundreds of points rapidly and accurately, without noise. Single-point precision is 12 µm, and feature precision is 2 µm. The system compares all dimensional components to the original CAD model, revealing both form and dimensional deviations within the manufacturing process.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
