An algorithm for generating tool positions for three-axis mill cutter paths on parametric surfaces is presented. The novelty of this algorithm is in its use of a surface subdivision technique as an alternative to the traditional APT-style iterative approaches based on local tangent-plane extensions. The algorithm presented provides global interference checking and does not exhibit the convergence problems of the traditional approaches
