Improving Reliability of GD&T Evaluations Using Portable Measuring Systems

Scott Sandwith, John Palmateer

GD&T is an engineering drawing language establishing consistent communication between design intent, manufacturing, and inspection. Book examples of the inspection are often illustrated by fitting parts within physical gages, and using dimensional...

Low-cost Photogrammetric Control for Automated Trimming of Composite Preforms

T.Legleu2, M.Mainwaring1, A.Metherell1, A.Ola1, V.Pawar2, C.Richards2, S.Robson2, B.Sargeant2, P.Saunders1 and R.Smith2

Trimming of composite preforms requires the accurate cutting of 2D and 3D high value components as part of a wider manufacturing chain. The operation needs to be performed rapidly and reliably with a fast high quality cut to avoid process bottlenecks and...

NPL Training –Structured approach to skills development for Science and Engineering

Keith Bevan

This presentation is delivered by Keith Bevan from The National Physical Laboratory and current CMSC Vice Chair looks at tools and techniques to support skills development, delivery, and evaluation. This structured approach supports the methodology needed...

Status Report for the Advanced Photon Source Upgrade Project

W. Jansma, S. Jarvis

The Advanced Photon Source (APS) is a third generation synchrotron X-ray facility located at Argonne National Laboratory that has been in operation since 1996. Over the next few years, the APS will undergo a massive upgrade that will replace the current...

Reverse Engineering Has Become An Integral Part of Modern Product Design

Gregory George

Every time you capture physical reality to use as part of your digital design process, you are engaging in reverse engineering. Whether you call it reverse engineering or something else, you are almost certainly, measuring physical parts and using those...

Modern Radar Metrology

Robert W. Strauten

The advancements in laser tracker technology have allowed portability of measurement solutions from system assembly through field installation and deployment. Accurate characterization of radar angular orientation and centering is paramount in optimizing...

LOW-COST ON-LINE PHOTOGRAMMETRIC 6DoF AT 100Hz TRACKING 10ms-1 MOTION ACROSS MULTIPLE OBJECTS

S.Robson, B.Sargeant, R. Smith, S. Kyle and M. Shortis

Low-cost camera systems based on off-the-shelf imaging components are seeing increasingly widespread use for metrology orientated research purposes such as robotics, part alignment and inspection. This presentation describes a system under continuing...

The Adaptive Measurement Template

Gerd Schwaderer

Measuring distorted parts automatically without local coordinate systems and manual interaction using scanning and adaptive measurement templates. Larger deformations in the range of the wall thickness or initial size of measurement area per geometry...

Surface Damage Catalog for Contact-measuring Space Flight Optics using a Coordinate Measuring Machine

Joshua Berrier

Autonomous Large Scale Weld Distortion Monitoring

Steve Seiler, Justin Novak

This paper will detail the development, testing, and integration efforts associated with a Near Real Time Weld Distortion Metrology System installed at Newport News Shipbuilding. This system was developed as a collaborative effort between Metrologists at...
