IGES Efficiency Evaluation

Abstract

This report describes the IGES Efficiency Study, a joint effort of Weapons Engineering Division (WED) and Materials Fabrication Division (MFD). The goal of the study was to quantify the impact of accurate geometry in design, manufacturing and inspection of mechanical parts. Two parts were designed, manufactured and inspected; and hemispherical and non-hemispherical part. Each part was designed in WED using CAD. Then three sources of numerical control (NC) tool paths and inspection probable paths were received in MFD: (1) an unchecked CAD/IGES database, (2) a guaranteed CAD/IGES database, (3) an electronic Hewlett-Packard Graphics Language (HPGL) file representing the CAD drawing.
