1. A computer-implemented method for generating a milling path for a bone, the computer-implemented method comprising:
obtaining a virtual model of the bone, a resection volume defined relative to the virtual model of the bone, and a reference guide defined with respect to the resection volume;
producing a plurality of section planes being successively arranged along the reference guide, and each section plane intersecting the reference guide and intersecting the resection volume;
generating a section path within each section plane and being defined relative to the resection volume;
generating transition segments for connecting section paths of section planes; and
combining the section paths and the transition segments to generate the milling path.
