Abstract
This study worked to find differences between the measurements of what parts should be and what they actually were. When a part is manufactured, it is given a nominal measurement which provides the exact geometric numbers representing that section of the part. The true measurements of parts are almost never exactly the same as the nominal measurement, due to varying production issues during component manufacture. A Hexagon Laser Scanner (LS) was used to create computer generated figures of the parts, while Siemens NX, CATIA V5, Creo, Solidworks, and Inventor softwares were used to create Computer-Aided Design (CAD) models of the parts. A Hexagon Coordinate Measuring Machine (CMM) evaluated accurate dimensions for each part. The tolerances between the nominal measurements of the parts and the measurements found by the CMM were determined. This study served to find differences in parts between their design and manufactured artifact, by creating multiple versions of computer-generated models and operating a CMM on the parts themselves. It is important to accurately assess graphics standards for the betterment of products in industry.
