In industry the key to excellent products is continual process improvement. Although process improvement is a timely procedure, results can be actualized through quality management and engineering concepts. This paper will analyze the production start-up of a copier frame and will further utilize process improvement strategies to improve the production process. The improvement strategies will include frame redesign, avoidance of material warpage due to welding, total quality management, as well as statistical process control guidelines. The frame redesign will look at eliminating unnecessary piece parts and reducing the overall production time and cost of the frame. This analysis will be conducted with the aid of Boothroyd and Dewhurst's (BDI) Design for Assembly (DFA) software. Next finite element analysis (FEA) and heat transfer techniques will be utilized to examine the warpage that the frames experience from welding. Algor SuperSap will be the software package utilized for the FEA. Finally, total quality management (TQM) and statistical process control (SQC) procedures will be examined. The best practices for this application have been implemented or will be recommended for future implementation.
