Abstract

The work presented in this paper is concerned with the design and development of an efficient computer software package for off- line programming of robots for spray coating. The developed package (called CA- COATS) allows the spray torch to track a path, maintaining the specified spraying distance and proper orientation relative to the part surface at all points, and thus ensuring uniform coating thickness. This software package is done off- line and is complete in itself, eliminating the need for another computer-aided design database of the base surface (although the package can be made to interface with such a database if so desired). Because the algorithm has no iteration, it is computationally efficient. With minor modifications, this package can also be extended to waterjet coating- removal systems.
