push touchscreen buttons to initiate the 3D scanning and inspection. Their Virtual Measuring Room (VMR) software accomplishes programming of the inspection routines, both online and offline. VMR aids in collision avoidance and pro- vides feedback to ensure part-feature inspection coverage. “This software also has a module specifically designed for blades, blisks, and stators for inspection analysis,” he said.
Stresses of Aircraft Production Ramp-ups As commercial aircraft manufactur- ers step up production, there are some lesser-known requirements they need to keep in mind. “One thing that is impor- tant is CAD model verification. If you are inspecting a part by relating your mea- surements to the CAD model, that model better be correct,” advised David Olson marketing and sales director for Verisurf (Anaheim, CA). This is especially impor- tant from his perspective, since Veri- surf’s comprehensive quality planning and reporting package is built on Model Based Definition. Such data is intimately tied to a correct CAD model. In the speed and rush of high-manufacturing volumes, with multiple variants of parts on the same line, it is a caution worth observing. Verisurf provides a handy tool in its software to validate any CAD model back to the original source, producing a report that can be included with, for example, First Article Inspections. Just as importantly, as aircraft production ramps up so, too, does the volume of metrology tasks that are re- quired. These will need to be performed by trained metrologists. The growth in new technologies, such as parts made of CFRP, is requiring new skills,too. “It is important now to train the next genera- tion of metrologists,” said Olson. In re- sponse, the company developed on-line training in its virtual Verisurf University.
“This is important to us. We consider it our responsibility to help train the next generation of metrologists,” he said. Interestingly, the plethora of new metrology devices such as scanners that can collect vast volumes of 3D point cloud
