Currently, inaccuracies in machine tools are often not detected until after they have produced nonconforming parts, causing reworking or scrap—which, for high-value aerospace parts—means significant lost costs. Additionally, low-value parts are often inspected less frequently, allowing many nonconforming parts to be produced before the issue is detected.
The alternative to relying on part inspection is to run frequent tests on the manufacturing equipment itself, but established calibration and health-check processes can be lengthy. While costly, emerging rapid and automated verification (RAV) processes enable machine tools to check their performance automatically in just a few minutes throughout the day, allowing machines to operate without human intervention for long periods of time. This SAE EDGE™ Research Report discusses the challenges and advantages of several key RAV solutions, from cost-effective artifact probing, to inertial measurement, and noncontact triple-probing.
NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. SAE EDGE™ Research Reports are not intended to resolve the issues they identify or close any topic to further scrutiny.
