Manufacturing Analysis and Process Optimization of Welded Parts

Berndt, Stephanie

Abstract Details

2013, MS, University of Cincinnati, Engineering and Applied Science: Mechanical Engineering.
This research focuses on improving the manufacturability and optimizing and estimating process time for plate cutting and welding processes. To this end, three distinct tools have been developed in this work: (1) Design for Manufacturability Anlaysis, (2) Optimal machine (cutting) time and (3) Accurate labor time estimation of welding process. This research extracts features from an AutoCAD dxf and applies sheet metal design for manufacturability rules to ensure cost effective and efficient assembly and manufacturing starting at the design phase. During the next phase of the manufacturing process, the tool path planning involved in manufacturing during the laser cutting process is optimized. An accurate time estimate is calculated by adapting a traveling salesman problem and determining the shortest laser traversal route by using a genetic algorithm. Finally, a weld time estimation program was developed to accurately estimate the weld assembly time by performing a comparative analysis of historical data. This research contributes in developing the most efficient means of welded parts manufacturing while estimating process time.
