High speed, high precision blade inspection

Turbine blade inspection, in both production and MRO conditions, presents a number of challenges including varying curved geometries as well as the high accuracy and precision requirements of aerospace application components.

WIZblade is a turnkey inspection system developed specifically for rapid high precision measuring of both aerospace jet engine blades and industrial turbine and compressor blades. WIZblade alignment, inspection and analysis are performed automatically during production and measurement of both unfinished (forged or cast) and finished (machined) blades. Its innovative on-line technology surpasses prior contact technology reliant upon precision fixtures, expensive tailored jigs and templates, or mechanical slow touch trigger and scanning probes. Instead, Wizblade uses the real-time adaptive control WIZprobe, Nextec’s advanced non-contact optical laser-scanning sensor for accurate geometric 3D measurements.

WIZblade | System Description

The WIZblade turn-key production-floor blade scanning solution comes with easy-to-use software for fast and accurate measuring and quality control of blades in repeatable measurements, inclusive of shiny and/or colored blade parts.

The automated laser WIZblade CMM relies upon the WIZprobe optical laser-scanning sensor instead of the conventional mechanical probe to measure blades. It has all the software functionality of WIZinspect plus many additional software modules dedicated for blades. To accommodate variance in blade geometry and size, the system comes with a variety of 3-axis motion platforms and optional rotary tables. WIZinspect has been designed with the flexibility to meet the needs of an array of blade manufacturers, designs and standards.
