Abstract Automated tape placement (ATP) is an important automated process adopted for the fabrication of large composite components. Trajectory planning key link ATP, which directly affects precision and efficiency layup quality final products. Presently, most existing trajectory optimization methods ATP focus on smooth surfaces. Nevertheless, as commercial CAD/CAM software generally uses NURBS (Non-uniform Rational B-Splines) modelling, difficulty finding solution low associated with calculation are inevitable. The discrete provide alternatives designing trajectories, whereas their accuracy seldom analysed. Furthermore, a path algorithm eliminating gap problems while preventing wrinkles models rarely reported. In this paper, adjustment trajectories considered triangular meshes. First, mesh reconstructed Nagata patch to recover original geometry good accuracy. Then, numerical method tracing desired paths set provided computation validated. Next, two methodologies proposed improve tapes avoiding wrinkles. Finally, presented strategies examined hyperbolic surface freeform some results delivered.
