A novel approach to optimal robot manipulator motion planning for Solid Freeform Fabrication (SFF) by thermal spraying is presented. In this approach, given the desired spatial geometry of the object, the motion of the spray gun relative to the forming platform is synthesized for minimal masking requirements considering the probabilistic nature of the thermal spraying process. The work being presented is part of an effort to develop a comprehensive geometric design methodology and the associated CAD/CAM software for SFF by thermal spraying. The software package, once fully developed, will interactively guide the designer to design parts such that they are manufacturable with minimal masking. The material build-up rate can be planned to achieve the desired distribution of the physical/material properties within the object volume. Examples of optimal motion planning for the generation of basic solid objects and computer simulation of the effectiveness of the developed methodology are presented and a number of related issues are discussed.
