There are pockets of Valisys users here at Boeing. The product has been in use for over 10 years here. I work in the Renton Division and was the team leader for piloting and testing across 3 Divisions of BCAG. We HAVE had very good success deploying and using Valisys here. I would say that there's nothing at the moment that captures the intent of ASME Y14.5 like the Valisys analyze engine. The product also offers us the ability to eliminate the "targeted coding" that comes with using the DMIS language, for every different machine type. It DOES require a rethinking of those persons who are used to a more traditional, "sequential" style of CMM programming, and therein lies the problem for most users. I've heard comments from detractors of Valisys that state that "you have to be a P.H.D. to use it..." IF that's the case, then I take it as a compliment to my programming staff, who are NOT college scholars. We've asked for better graphical tools and more "ease of use" enhancements to be sure, so there is definately room for improvement in the product across the board. We have concerns about the operability with V5 CATIA (the cad system of choice here at Boeing - for the most part currently running at V4 level). While Valisys is currently a company-wide standard, there are products out there competing heavily for Boeing's business. They offer NT based solutions which possess some nifty graphical tools. For now, and for my operation, I consider Valisys to be the cream of the crop, because we use it for more than just CMM programming. It will be very interesting to see what transpires in the near future with the migration to V5 CATIA and DELIMIA's upstart Inspection program. We've provided extensive requirements to DELMIA and it will be anyone's guess as to whether they can truly compete in functionality.
