Abstract
Abstract This paper addresses the research and development of a Computer-Aided Manufacturing (CAM) software package used for fabricating Profiled-Edge Lamination (PEL) tooling. Background research in PEL tooling is reviewed and possible applications for PEL tooling in seven different manufacturing processes are examined. The general PEL tooling process is outlined and the fundamental role that the CAM software plays in this process are discussed. The CAM software is used to create and simulate appropriate line-of-sight cutting trajectories for an Abrasive Water Jet (AWJ) cutting machine. Using this CAM software, PEL cutting trajectories and the resulting PEL tool shape can be compared with the original CAD tool shape. After the tool shape is evaluated, the CAM software exports CNC G-code to an AWJ cutting machine for cutting individual laminations. Four algorithms have been developed to create suitable cutting trajectories for PELs. Each algorithm is evaluated through simulation using the benchmark tool shape. As a result of this evaluation, one particular algorithm was found to be the most promising because it 1) successfully produces sharp edges with no loss of original shape, 2) allows unlimited tool orientation, and 3) better handles complicated tooling geometries. Finally, future work to validate the cutting trajectory algorithms is outlined.
