From ‘Impossible’ to Remarkable: Leonardo cuts production time from 20 weeks to 3 days for tiltrotor blades

Global industrial group, Leonardo, has experienced a remarkable leap in its production of complex carbon-fibre tiltrotor blades for one of its leading helicopter programmes after advanced CNC metrology solutions from MSP cut production time from 20 weeks to 3 days.
As part of this, Leonardo has also seen their part alignment process reduced from days to 5 minutes, their estimated scrap rate reduced from 95% to 0% and their reliance on using fixtures for part alignment processes eliminated.
Faced with the challenge of producing large, twisted composite blades that were deemed ‘impossible to manufacture’ by simulation software due to varying levels of distortion and a thin tip making them hard to fixture, Leonardo turned to MSP’s PerfectPart suite of metrology products.
David Madigan, Tooling Design Engineer at Leonardo, explained: “To align our parts, we would normally probe and measure parts using the CAD, but as the composite blades are often all different and never conform to this data, we had to find another way”.
Originally, Leonardo considered tackling the problem themselves using traditional manufacturing methods, but this was predicated to create a 18-20 week lead time and, therefore, deemed as an unsuitable solution.
Help came in the form of MSP’s NC-Checker and NC-PartLocator, from the MSP PerfectPart metrology suite of products, both of which are designed to give manufacturers error-free and right-first-time part production.

MSP PerfectPart cut the production time of Leonardo’s tiltrotor blades from 20 weeks to 3 days.
NC-Checker was introduced as a standard operating procedure at Leonardo for its ability to assess the geometric performance of a CNC machine tool to check it is capable of machining parts to tolerance.
David stated: “The tiltrotor blades are low-volume and high-value, so you don’t want to risk scrapping any. NC-Checker allows us to monitor the machine tool in a simple way and gives us the confidence that no error on the machine will negatively impact the parts. Before we machine a blade, it is a stipulation that the software is run. Then, if something does go wrong, the first question is ‘Well, did you run NC-Checker?”.
NC-PartLocator was introduced to solve Leonardo’s main challenge of accurately aligning the blades despite the unknown amounts of distortion. NC-PartLocator is different to traditional part alignment methods. The software uses 5-axis probing to measure a part on the machine and generate an accurate best fit alignment in 6-degrees of freedom.
Most importantly in Leonardo’s case, the software compensates for any discrepancy between the physical part location and the nominal machining program to show where the part ‘really is’ on the machine. The updated alignment is automatically uploaded to the controller and any misalignment errors are automatically removed.
David admitted the product shocked him: “NC-PartLocator’s alignment results can be quite surprising. The software often shows that the blade should be somewhere else entirely, even when it doesn’t look any different on the surface”.
It’s also aided David’s fixturing routine: “I designed the fixtures based on the fact that you move the machine to the part instead of moving the part. All I needed to do was hold the part in position so it could be probed. It didn’t matter that the blades were all variable and the position wasn’t correct as I knew NC-PartLocator would compensate for that.
“It’s night and day compared to traditional methods”.

And the results certainly show this difference. Using MSP as part of its processes, Leonardo has cut its estimated 20-week production time and 95% scrap rate to a stable 3-day production time with a potential for 0% scrap rate.
From parts that were deemed ‘impossible to manufacture’ to a manufacturing process that takes 3 days, Leonardo’s transformation is an example of how powerful advanced manufacturing metrology can be for composite and complex machining issues.
