© 2019 The Authors. Published by Elsevier B.V.Current methods used to generate toolpath in 5-axis machining, multiply the program lines when the precision is sought, producing a deficient approach to the points and a highly variable feed rates. These factors cause geometric imprecision and poor surface finishes. In this work, a new method for approximating trajectories through circular arcs between selected points has been developed. It has been checked through the machining of an elliptical toroid surface and its results have been compared with those produced by other CAM strategy. The part produced by the new method shows a considerable improvement in the surface roughness.
