RESUMO

This dissertation concerns the performance evaluation of machine-tool with architectures based on planar parallel kinematic structures. The text starts analyzing two distinct types of parallel architectures, their mobility, feasible schemes of actuation and presents their kinematic and dynamic models. From this point, simulations are described to figure out some characteristics of chosen architectures, in eight different models, focused on execution of tool trajectories in plane motion (2D). The model selection and the discussion about obtained results are guided by performance indexes from the literature and others either proposed or adapted. The work also discusses the best solutions, for pre-defined tool trajectories and important points for mechanisms with parallel structures.
