Verifying Assemblies Using CT Scans and Geomagic Solutions

Rus Emerick, Global Process Owner for 3D Imaging at Schneider Electric, spends a lot of time thinking about tolerances. Starting with tolerances of individual parts, his brain moves swiftly on to the effect of chains of tolerances that, once you get to 4, 5 or more parts in an assembly, could cumulatively affect the reliability of the products being made at any of their manufacturing and design sites in 22 countries around the world. But how can the consistency of assemblies be verified before and during production? Using traditional destructive testing was proving inefficient, slow and often did not help the team verify consistency in the parts and assemblies. Dynamic tolerance analysis of these assembled parts was even more of a challenge. Money was being wasted. There had to be a better solution and Emerick knew that 3D data would continue to provide the answers he needed.

Schneider Electric ( has been in operation for more than 170 years, evolving through iron and steel, heavy equipment and into electrical and automation management products. Products and services cover electrical distribution, industrial automation, critical power & cooling, building management and security, with manufacturing plants at key manufacturing centers across the world.

Emerick, a specialist in process improvement, is something of a trailblazer in the organization, finding and implementing solutions that are designed to improve 6 Sigma practices, working with production teams on supporting lean manufacturing techniques in an effort to reduce costs and waste in the engineering-to-production workflow. His work is to design processes that can be methodically implemented across each of the manufacturing plants, allowing best practices to become standard at each site. His focus is on verification of products using 3D data. For 10 years, he has worked very successfully with automated inspection in the production lines, using Laser Designs’ Surveyor 3D scanners and Geomagic® Control™ (formerly Geomagic Qualify®) to measure, inspect and report on products. Since the demand for better, more efficient manufacturing never lets up, so Emerick keeps the pressure on his team, some 125 strong, to find new, faster and better ways for 3D data to improve product quality.
