Myths Debunked

Most industrial gas turbine engine manufacturers have yet to catch onto the successes now enjoyed by other precision manufacturers, and are still wasting too much time and money on obsolete 20th-century inspection methods and equipment.

Whichever manufacturers
are the quickest to adopt modern 21st-century quality inspection methods will gain enormous advantage and likely come to dominate their market, as we have seen in other industries.

Level 3 Inspection is issuing a series of educational emails intended to address a few of the cherished myths and assumptions that have kept the industrial gas turbine
industry in the comfortable past — till now.

Myth #1

"We've always used CMM's! They're the best inspection tool on the market!"


The Truth

CMM’s are all too common among industrial gas turbine engine manufacturers and in their supply chain ... but CMM's are no longer the best option.



CMM's Mislead You!

A CMM's accuracy depends on at least three factors — repeatable fixturing properly used, diligent operator experience, and reliable sequence programming — any of which can introduce or compound errors.  Moreover, CMM's generally collect far too few measurement points to provide discernible surface profiles and are not generally easy to confidently interpret.  Instead of fully visualized surface profiles, CMM’s produce tabulated data from a relatively small number of test points, from which it’s impossible to reliably discern meaningful shapes and patterns.

3D surface digitization through White Light Scanning (WLS), when correctly implemented, overcomes all of these problems. When followed by Computer Aided Inspection (CAI), it offers a wide spectrum of tangible advantages to any manufacturing process, including visualization of entire part geometry for greater understanding, with accuracy, comprehensiveness, automation, and speed.



White Light Scanning (WLS) is now Fast and Automated!

Traditionally, white light scanners have required years of experience in order to yield useful data.  Many industrial gas turbine engine manufacturers have spent substantial capital on WLS equipment that does not provide the results, understanding and confidence they sought to gain. Expertise in this new field provides tremendous advantages.

With the SiS™, the CAI industry leaders at L3I have brought their decades of application experience to bear on this problem.  For the first time, WLS and CAI reports containing thorough, accurate and useful 3D digitized surface plots can be generated in just minutes by an in-house shop-floor technician with minimal training. The inspection process variables have been systemized and automated, for speed and confidence.

The SiS™ is now available to be custom-configured to meet the needs of forward-thinking industrial gas turbine engine manufacturers and of their supply chain.  Call us today to learn how to get your SiS solution on its way.
