Abstract
Local and global evaluation methods for shape errors of free-form surfaces are presented. The local evaluation methods use the changes of principal cu rvatures between the original CAD data and actual surfaces. The global eval uation methods use the aggregate normal vectors for the characterization of portions of surfaces. Both methods are applied for the evaluation of sheet metal formed by using numerical simulation data and coordinate measurement data. (C) 1999 Elsevier Science Ltd. All rights reserved.
