MEASUREMENT IN AEROSPACE


Aubrey reports that ShapeGrabber’s desktop Ai310 system is a popular choice among aerospace users, though the company delivers larger systems as well. Due to the very high point density (a few million points is typical) the measurements can easily be compared directly to the 3D CAD model, which is increasingly being demanded by users. Moreover, the setup does not require programming knowledge. “The fi rst time the part is measured, the steps are automatically recorded. So the next time, the operator just loads the part and runs the previ- ously recorded steps, and the inspection report is automati- cally generated,” said Aubrey. Scan volumes and accuracies are dependent on the choice of scanhead installed. The company offers vari- ous scanheads to more easily satisfy the various needs of customers. The most accurate system boasts a resolution of 2 µm with a 50-mm fi eld of view; the largest scan volume scanhead has a fi eld of view of 630 mm with a resolution of 40 µm. ShapeGrabber provides accuracy numbers to the ISO 10360-8 international standard, according to Aubrey.


How does he see the future? “Our customers will always


want more speed and accuracy,” he said. Faster measure- ment means better return on investment. Although the cur- rent accuracies satisfy a large number of applications, he sees greater accuracies as opening more opportunities for 3D scanning. Aubrey said his company will continue refi n- ing its systems because customers want to replace slower methods now in use with noncontact measurement. “The trend...for dimensional metrology equipment is continuing towards speedier, more portable, and easier to use solutions,” said senior research analyst Aravind Govindan of Frost and Sullivan (Mountain View, CA). Noting that the tried and true CMM still retains 50–60% of the market share, the fi rm’s research sees that share changing as customers choose the speed of nontraditional optical, white light, and laser scanning metrology. “These technologies are improving as well,” he said. “Additionally, many users are willing to trade some accuracy for speed and usability.”

Frost and Sullivan has also found that noncontact technology is gaining greater acceptance in Tier Two and Tier Three companies. “We see the adoption rate faster in these companies because of the cost-effectiveness of the solutions and the value they bring,” Govindan said.
