A measurement system analysis (MSA) is a thorough assessment of a measurement process, and typically includes a specially designed experiment that seeks to identify the components of variation in that measurement process. Just as processes that produce a product may vary, the process of obtaining measurements and data may also have variation ...
Test automation is a big part of a test engineer's job. The whole intention of automating the test is as follows: Enforce test steps to be followed within specifications and correct timing. Eliminate manual command and data inputs. Automate data gathering. Enforce test process flow.
Industrial CT scanners use X-rays to image an object from many angles, building up a 3D image to compare to a specification. [6] CT scans can be used to analyse the internal geometry of parts because the X-rays penetrate the object being scanned. Higher resolution CT scans can also check for cavities, cracks, and other undesirable features ...
Probing systems for microscale metrology applications are another emerging area. [6] [7] There are several commercially available coordinate measuring machines that have a microprobe integrated into the system, several specialty systems at government laboratories, and any number of university-built metrology platforms for microscale metrology ...
As the output of 3D scanning processes, point clouds are used for many purposes, including to create 3D computer-aided design (CAD) or geographic information systems (GIS) models for manufactured parts, for metrology and quality inspection, and for a multitude of visualizing, animating, rendering, and mass customization applications.
A structured-light 3D scanner is a device used to capture the three-dimensional shape of an object by projecting light patterns—such as grids or stripes, onto its surface. [1] The deformation of these patterns is recorded by cameras and processed using specialized algorithms to generate a detailed 3D model .
An Automated Optical Inspection device. Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew).
