  Variation Systems Analysis

  Jan 1990 - Sept 1999

  Consultant Engineer

  Dimensional Engineering Consultant Provided automotive and aerospace clients with dimensional engineering expertise to improve quality and reduce build variation. Created 3-D tolerance models and GD&T (Geometric Dimensioning and Tolerancing) documents. Developed measurement plans. Analyzed CMM data to resolve manufacturing build issues.- Improved the flight performance of the Northrop Grumman's Gulfstream V by integrating a tolerance model with a finite element stress model to predict wing twist variation and recommended design improvements.- Improved body fit quality for Chrysler's minivan by using a portable CMM to measure the tooling locators in the body shop during program launch.- Successfully tested and help improve the beta version of CATIA VSA 3-D software while modeling the Jeep Liberty body and closure fits.- Improved the dimensional fit of the GM midsize deck lid to the body using a kinetic tolerance model that simulated the motion of the six bar hinge.

  General Motors

  Oct 1999 - Jan 2009

  Dimensional EngineeringDeveloped dimensional strategies for body structures and closures. Ensured that dimensional strategies and enablers were incorporated into advanced vehicle programs. Evaluated product design and manufacturing requirements and reported predicted performance of dimensional objectives to the program team. Identified and resolved dimensional issues throughout the product development cycle.- Improved quality by identifying dimensional enablers successfully incorporating them into the advanced product design for next generation midsize car program.- Reduced manufacturing costs and improved quality through team development of new rear opening structure design and build strategy for vehicles with liftgates.- Improved quality by leading team development of dimensional locating strategies for key body assemblies that were posted on the General Motors internal web to serve as templates for all future global programs.
